BACKGROUND OF THE INVENTION

Increasingly, consumers demand impactful and long-lasting fragrance on their laundry, even weeks after washing. It is also desirable to enhance consumer experience by releasing fragrance at different consumer contact points, such as point of purchase, when opening the door of a washing machine or dryer, as well as during the storage, ironing and wearing of clothing. Laundry care products, such as detergents, fabric conditioner compositions and scent booster compositions enable consumers to enjoy the magical fragrance experience during these different stages of the laundry care process.

Fabric conditioner compositions are water-based textile conditioning compositions primarily intended to be added to a washing machine during the rinse-cycle of a clothes-washing process. The major component of a fabric conditioner composition is a cationic surfactant, which softens textiles and offers static control. Apart from this surfactant, they typically contain minor amounts of other materials, such as emulsifiers. It is known to add cellulase enzymes to fabric conditioner compositions. In particular, enzymes have been employed to improve the condition of textiles (e.g. reduce pilling), and as well to improve water-absorbency of textiles. It is also conventional for fabric conditioner compositions to include aesthetic additives, such as colours and perfumes.

With consumer demand for smaller dosage formats (e.g. unit dosage forms) and the general public interest in reducing the consumption of the planet’s resources in order to satisfy our consumer product needs, there is a desire to reduce the solids content in these products. In order to achieve this, it is necessary to reduce levels of the major component used in these products, more particularly cationic surfactants, whilst still delivering excellent conditioning performance and textile care. Although it is conventional to think of perfume as merely an aesthetic ingredient, in fact it is not used in consumer products simply to ensure the products and textiles treated with exhibit a pleasant smell. Consumers actually benefit from additional value brought to their consumer products by perfume design. The ability of a perfume to enhance the attributes of a consumer product has been known to manufacturers of consumer products for decades. The pleasant odour remaining on a shirt after ironing informs the wearer that not only is it clean and fresh, but it is almost new again. The user of a deodorant stays “fresh” even after a hard day at the office. The floor cleaner has not only cleaned the floor, but the room remains “clean” after many hours.

Skilled perfumers can achieve both desirable hedonics, as well as all manner of such secondary functional benefits because they understand how perfumes interact with the complex chemistry used in consumer products, as well as the chemistry of the targeted substrates. For example, it is generally known that the softness of laundered garments is achieved by delivering a cationic surfactant to the surface of the fabric. It is also known that perfume ingredients associate with surfactant aggregates and absorption of perfume is concomitant with the deposition of cationic surfactants on a textile. In this way, cationic surfactants actually promote perfume deposition and therefore perfume impact on freshly laundered fabrics. Furthermore, if the perfumer uses perfume ingredients that are empirically known to deposit well on fabrics, then the initial deposition on wet fabric can be translated into improved perfume tenacity and odour impact during dry down and subsequently during storage and use by consumers. Conversely, reducing the level of cationic surfactants may reduce the deposition of perfume and limit its olfactive performance on both wet and dry stages of the washing cycle.

As the consumer product industry undertakes the task of modifying laundry care products to reduce reliance on unsustainable petrochemical materials, such as cationic surfactants, in order to satisfy customer demand for sustainable products, perfumers need to adjust and adapt their perfume design principles to balance hedonic and functional effects having regard to the new realities of consumer product chemistry. More particularly, perfumers need to counteract any attenuation or modulation of olfactive signal from a perfume delivered from a consumer product containing reduced levels of surfactant, and in particular of cationic surfactant.

There remains a need to optimize perfume design to create, modify, improve or augment the olfactive impression of one or more perfume ingredients in a perfume composition when deposited onto a textile from a laundry care product, such as a fabric conditioner, and particularly such products containing reduced levels of cationic surfactant.

SUMMARY OF THE INVENTION

The applicant found that the odour impression of a perfume composition delivered onto a textile from a laundry care product can be modulated depending on whether and to what extent the textile is treated or has been treated with cellulase enzymes. More particularly, the applicant found that in products containing a cellulase enzyme, and particularly those containing reduced levels of cationic surfactant, certain perfume ingredients deposited more preferentially on textiles treated with those products, compared with similar products that did not contain cellulase enzymes. The surprising discovery that the affinity of certain perfume ingredients for a textile surface can change depending on whether or not the textile has been treated with a cellulase enzyme, provides the skilled perfumer with a means to alter the olfactive impression of a perfume deposited onto a textile. Accordingly, through the judicious selection of perfume ingredients that exhibit a heightened affinity for cellulase-treated textile, it is possible to change the olfactive impression of a perfume to create new hedonics that particularly can create, modify, improve or augment fresh, floral, sweet, creamy and oriental notes; or to create new functional effects, such as improving or increasing the bloom intensity or room-filling intensity of a perfume.

More particularly, the applicant found a group of perfume ingredients that exhibited a particularly pronounced modulation of olfactive impression when deposited on cellulase-treated textiles, so much so that the olfactive impression is detectable by human subjects exhibiting normal olfactive acuity. Still more particularly, the applicant has found that there was a relationship between the propensity of a perfume ingredient to deposit preferentially on enzyme-treated cotton-containing textiles, compared to untreated cotton-containing textiles and the molecular features of these ingredients.

In particular, the applicant has found that the deposition of perfumery ingredients on cellulase- treated cotton is governed by two contributions: a first contribution which is reflected by a high ClogP value, and a second contribution, which is referred to herein as an ingredient’s Affinity Factor and is associated with the presence of electron-rich chemical functionalities, such as aromatic rings; nitrogen-containing functionality, including N-atoms in a heterocycle, nitrile, amine, oxime, and amide; carbonyl functionality; carbon-carbon double or triple bonds; and secondary or tertiary hydroxyl functionality. Thus, ingredients having a high ClogP or ingredients having the chemical functionalities mentioned hereinabove, or ingredients that are both high ClogP and possessing the aforementioned chemical functionality, particularly when those ingredients have a molecular weight Mw of 200 g/mol or higher, exhibit enhanced deposition on treated textiles compared with how they deposit on untreated cotton-containing textiles.

Accordingly, the invention provides in a first aspect a laundry care product comprising a cationic surfactant, a cellulase enzyme and a perfume composition, wherein the perfume composition comprises: at least one ingredient having a ClogP of 3 or greater ingredient; and/or at least one ingredient having an Affinity Factor A that is equal to or greater than 3 wherein the Affinity Factor A is given by the following formula (Equation 1):

A = 2(Ar) +nN+nstOH+nAld+nLac+nKet+nDB+0.5(nEst) wherein

- Ar refers to an aromatic ring, and takes the value of 2 if one or more aromatic ring is present in the ingredient, or zero if the ingredient contains no aromatic rings; nN refers to a nitrogen-containing functional group, including N-atom in a heterocycle, a nitrile, an amine, an amide, or an oxime, and takes the value of the number of such functional groups contained in the ingredient; nstOH refers to secondary or tertiary hydroxyl functional group, and takes the value of the number of such functional groups contained in the ingredient; nAld refers to aldehyde or alpha-beta unsaturated aldehyde functionality, and takes the value of the number of such functional groups in the ingredient; nLac refers to a lactone functional group, and takes the value of the number of lactone or also pyranone functional groups in the ingredient; nKet refers to a ketone functional group, and takes the value of the number of ketone or alpha-beta unsaturated ketone functional groups in the ingredient; nEst refers to an ester functional group, and takes the value of the number of ester or alpha-beta unsaturated ester functional groups in the ingredient; and nDB refers to double or triple carbon-carbon bonds and takes the value of the number of double or triple bonds in the ingredient, with the proviso that if the double bond is present in any of the foregoing functional groups or is present in aromatic unsaturation, then it is not taken into consideration in determining the value of nDB.

ClogP is the calculated octanol/water partition coefficient. In the context of the present invention, ClogP is calculated by using the calculation software embedded in ChemDraw professional software version 18.1 .0.535. ChemDraw is part of the ChemOffice software platform commercialized by Perkin Elmer.

The invention provides in a second aspect a method of creating, modifying, improving or augmenting the olfactive impression of one or more perfume ingredients in a perfume composition deposited on a textile, the method comprising the step of the simultaneous, sequential or separate treatment of the textile with a perfume composition as defined herein and a cellulase enzyme.

The invention provides in a third aspect the use of an enzyme having cellulase activity in a laundry care product for creating, modifying, improving or augmenting the olfactive impression of one or more perfume ingredients in a perfume composition as defined herein, deposited on a textile from a laundry care product.

The embodiments, examples and preferences provided in relation to any one or more of the stated aspects of the present invention will be further described herein and apply equally to all aspects of the present invention. Any combination of the embodiments, examples and preferences described herein below in all possible variations thereof is encompassed by the present invention unless otherwise indicated herein, or otherwise clearly contradicted by context.

DEFINITIONS

Bloom: The term is a measure of intensity of a perfume signal that is assessed by skilled evaluators immediately on opening the window of a wash machine (so-called “out of the machine” stage) and at a distance of from 0.5 to 2 meters from the window. Assessment is made according to a standardized procedure, an example of which is further described in Example 3, below.

Cellulase: The term “cellulolytic enzyme” or “cellulase” or “enzyme having cellulase activity” means one or more (e.g., several) enzymes that catalyze the decomposition of cellulosic material by hydrolysis of beta-1 , 4-glycosidic bonds. Such enzymes include endoglucanase(s), cellobiohydrolase(s), beta-glucosidase(s), or combinations thereof. The two basic approaches for measuring cellulolytic activity include: (1) measuring the total cellulolytic activity, and (2) measuring the individual cellulolytic activities (endoglucanases, cellobiohydrolases, and betaglucosidases) as reviewed in Zhang et al., Outlook for cellulase improvement: Screening and selection strategies, 2006, Biotechnology Advances 24: 452-481. Total cellulolytic activity is usually measured using insoluble substrates, including Whatman N°1 filter paper, microcrystalline cellulose, bacterial cellulose, algal cellulose, cotton, pretreated lignocellulose, etc. The most common total cellulolytic activity assay is the filter paper assay using Whatman N°1 filter paper as the substrate. The assay was established by the International Union of Pure and Applied Chemistry (IUPAC) (Ghose, 1987, Measurement of cellulase activities, Pure Appl. Chem. 59: 257-68).

For purposes of the present invention, cellulolytic enzyme activity may be determined by measuring the increase in hydrolysis of a cellulosic material by cellulolytic enzyme(s) under the following conditions: 1-50 mg of cellulolytic enzyme protein/g of cellulose in PCS (or other pretreated cellulosic material) for 3-7 days at a suitable temperature, e.g., 50°C, 55°C, or 60°C, compared to a control hydrolysis without addition of cellulolytic enzyme protein. Typical conditions are 1 ml reactions, washed or unwashed PCS, 5% insoluble solids, 50 mM sodium acetate pH 5, 1 mM MnS04, 50°C, 55°C, or 60°C, 72 hours, sugar analysis by AMINEX® HPX- 87H column (Bio-Rad Laboratories, Inc., Hercules, CA, USA).

The cellulases applied in the present invention may be expressed with or without signal peptide or with part of the signal peptide depending on the actual expression conditions.

Fabric softener: A Fabric softener (also referred to herein as fabric conditioner, fabric conditioner composition or solely softener) is a composition that is typically applied to laundry during the rinse cycle in a washing machine or when washing by hand. Fabric softeners coat the surface of a fabric with chemical compounds that are electrically charged, neutralizing the charge of the fabric and causing threads to "stand up" from the surface so the fabric feels softer and makes it fluffier. Fabric softeners are available as solutions and solids and may also be impregnated in dryer sheets used in a clothes dryer.

Fabric softener agent: A fabric softener agent (or a softener agent) is an ingredient that is comprised in fabric softener compositions such as chemical compounds that are electrically charged. These compounds cause threads in the fabric to lift up from the surface of the textile and thereby give the fabric a softer feel of the textile. In one embodiment the fabric softener agent is one or more cationic softeners. The softener will usually comprise from about from about 0.5% to about 40% by weigh of a cationic surfactant, for example from about 0.5% to about 30%, in particular from about 1% to about 20%, from about 3% to about 10%, such as from about 3% to about 5%, from about 8% to about 12% or from about 10% to about 12%. Non-limiting examples of cationic surfactants include bis(Acyloxyethyl)hydroxyethyl Methylammonium Methosulphate, Dipalmoylethyl hydroxyethylmonium methosulfate, dihydrogenated tallow hydroxyethylmonium methosulfate, distearoylethyl hydroxyethylmonium methosulfate, dioleoyl ethyl hydroxyethylmonium methosulfate alkyl quaternary ammonium compounds, alkoxylated quaternary ammonium (AQA) compounds, other ester quats, and combinations thereof. The cationic softeners bind by electrostatic attraction to the negatively charged groups on the surface of the textile and neutralize their charge and thereby impart lubricity.

Fragment: The term “fragment” means a polypeptide having one or more (e.g., several) amino acids absent from the amino and/or carboxyl terminus of a mature polypeptide main; wherein the fragment has enzyme activity. In one aspect, a fragment contains at least 85%, e.g., at least 90% or at least 95% of the amino acid residues of the mature polypeptide of an enzyme.

Family GH45 cellulase: the term “family GH45 cellulase” as used herein, refers to Glycosyl hydrolases are enzymes that catalyze the hydrolysis of the glycosyl bond. There are over 100 classes of Glycosyl hydrolases which have been classified, see Henrissat et al. (1991) A classification of glycosyl hydrolases based on amino-acid sequence similarities', J. Biochem. 280: 309-316 and the CAZY website at www.cazy.org. The glycoside hydrolases of family 45 (GH45) have so far been identified as endoglucanase (EC 3.2.1.4). Within the definition falls enzymes which are commonly known as “cellulases”. Such enzymes comprise also enzymes that may be known as endoglucanases.

Laundry Care Product: The term “laundry care product” refers to products, particularly detergent and surfactant products that are used to create an effect on a treated textile including stain or soil removal; bleaching, disinfecting, softening or conditioning; or to impart colour or a pleasant fragrance. The term includes, but is not limited to fabric softeners and scent-boosters.

Room-Filling: The term refers to a measure of intensity that is assessed by skilled evaluators at a defined time (for example between 15 and 60 minutes) after the fabric has been put to line drying, at a distance of from 0.5 to 2 meters from the line. Assessment is made according to a standardized procedure, an example of which is further described in Example 3, below.

Rinse cycle: The term “rinse cycle” is defined herein as a rinsing operation wherein textile is exposed to water for a period of time by circulating the water and optionally mechanically treat the textile in order to rinse the textile and finally the superfluous water is removed. A rinse cycle may be repeated one, two, three, four, five or even six times at the same or at different temperatures.

Scent booster: A scent booster is a composition that is applied to textiles during the laundry process to impart a long-lasting fragrance impression to textiles particularly during dry stages such as storage, ironing or wearing of clothing. Scent boosters typically comprise free and/or encapsulated fragrance oil entrained in a solid matrix material. Typically, a scent booster is presented in a granular or pastille format.

Sequence identity: The relatedness between two amino acid sequences or between two nucleotide sequences is described by the parameter “sequence identity”.

For purposes of the present invention, the sequence identity between two amino acid sequences is determined using the Needleman-Wunsch algorithm (Needleman and Wunsch, 1970, J. Mol. Biol. 48: 443-453) as implemented in the Needle program of the EMBOSS package (EMBOSS: The European Molecular Biology Open Software Suite, Rice et al., 2000, Trends Genet. 16: 276- 277), preferably version 5.0.0 or later. The parameters used are gap open penalty of 10, gap extension penalty of 0.5, and the EBLOSUM62 (EMBOSS version of BLOSUM62) substitution matrix. The output of Needle labeled “longest identity” (obtained using the -nobrief option) is used as the percent identity and is calculated as follows:

(Identical Residues x 100)/(Length of Alignment - Total Number of Gaps in Alignment) Signal peptide: A "signal peptide" is a sequence of amino acids attached to the N-terminal portion of a protein, which facilitates the secretion of the protein outside the cell. The mature form of an extracellular protein will often lack the signal peptide, which may be cleaved off during the secretion process.

Textile: The term “textile” as it is used herein refers to any textile material including yarns, yarn intermediates, fibers, non-woven materials, natural materials, synthetic materials, and any other textile material, fabrics made of these materials and products made from fabrics (e.g., garments and other articles). The textile or fabric may be in the form of knits, wovens, denims, non-wovens, felts, yarns, and towelling. The textile may be cellulose based such as natural cellulosics, including cotton, flax/linen, jute, ramie, sisal or coir or manmade cellulosics (e.g. originating from wood pulp) including viscose/rayon, cellulose acetate fibers (tricell), lyocell or blends thereof. The textile or fabric may also be blends of cellulose based and non-cellulose based fibers. Examples of blends are blends of cotton and/or rayon/viscose with one or more companion material such as wool, synthetic fiber (e.g. polyamide fiber, acrylic fiber, polyester fiber, polyvinyl chloride fiber, polyurethane fiber, polyurea fiber, aramid fiber), and/or cellulose-containing fiber (e.g. rayon/viscose, ramie, flax/linen, jute, cellulose acetate fiber, lyocell). Fabric may be conventional washable laundry, for example stained household laundry. When the term fabric or garment is used it is intended to include the broader term textiles as well.

The textile contemplated in the present invention may be any pure form, such as 100% cotton, 100% polyester or the like, or it may be any blend of different types of textile, such as 50% cotton and 50% polyester. Thus, in one embodiment, the textile is a mixture of at least 50% polyester and at least 20% cotton.

The textile may have been pre-washed (treated) in a laundering process. The laundering process may be done at various temperatures depending on the textile, the level of dirt on the textile, or any other aspect that may be dependent on the temperature. The invention is not limited to any specific temperature. Thus, in one embodiment, the pre-washing has been done at a temperature of at least 5°C, such as at least 10 °C, at least 15 °C, at least 20 °C, at least 25 °C, at least 30 °C, at least 35 °C, at least 40 °C, at least 45 °C, or at least 50 °C, or at least 60 °C.

Variant: The term “variant” means a polypeptide having enzyme activity comprising an alteration, i.e., a substitution, insertion, and/or deletion, at one or more (e.g., several) positions. A substitution means replacement of the amino acid occupying a position with a different amino acid; a deletion means removal of the amino acid occupying a position; and an insertion means adding an amino acid adjacent to and immediately following the amino acid occupying a position. Wash cycle: The term “wash cycle” is defined herein as a washing operation wherein textile is exposed to the wash liquor for a period of time by circulating the wash liquor and textile in a washing machine. A wash cycle may be repeated one, two, three, four, five or even six times at the same or at different temperatures. The wash cycle if often followed by a rinse cycle and finally a centrifugation cycle where water is removed from the textile. It is known for the skilled person to determine which is the wash cycle during laundry wash.

Wash liquor: The term “wash liquor” is intended to mean the solution or mixture of water and detergents optionally including enzymes used for laundry.

DETAILED DESCRIPTION OF THE INVENTION

The present invention relates to the use of perfume compositions and cellulase enzymes in combination to create, modify, improve or augment the olfactive impression of one or more perfume ingredients deposited onto a textile treated with a cellulase enzyme, as well as the design of perfume compositions for use in laundry care products containing cellulase enzymes, and particularly those laundry care products containing reduced levels of cationic surfactants. The applicants have found that by treating textiles with cellulase enzymes and specifically designed perfume compositions in laundry care products, the olfactive impression of one or more perfume ingredients in the perfume composition can be modulated in a manner that is detectable by people with normal olfactive acuity during all stages of the laundry process, as well as during storage and subsequent use. Still more particularly, the modulation effect of the olfactive impression increases over multiple wash-cycles using a cellulase enzyme.

Conversely, perfume compositions not constructed in accordance with the present invention do not exhibit the aforementioned synergies with cellulase enzymes, or at least not to any extent that would be perceivable by a person with normal olfactive acuity.

The invention also relates to a method for improving the condition of a textile comprising contacting the textile surface with a cellulase enzyme, and particularly a cellulase enzyme in combination with a cationic surfactant. In particular, in relation to fabric conditioner compositions, the applicants found that despite reducing the level of cationic surfactant employed in a fabric conditioner composition, conditioning and anti-static properties remain unaffected, but anti-pilling properties were nevertheless improved over multiple wash-cycles, by adding effective levels of a cellulase enzyme to the composition.

In accordance with the first aspect of the present invention, perfume ingredients meeting one or both contributions referred to hereinabove, exhibit an increased propensity to deposit preferentially on enzyme-treated cotton-containing textile. Furthermore, the higher the ClogP of an ingredient, and/or the higher its Affinity Factor, the higher will be the differential of deposition between untreated cotton-containing textiles and cotton-containing textiles treated with cellulase enzymes.

In particular embodiments of the invention, the perfume composition contains at least one ingredient meeting both contributions, that is a ClogP of 3 or greater, or more particularly 3.5 or greater, or still more particularly 4 or greater, and an Affinity Factor equal to or greater than 3, greater than 3.5, greater than 4, greater than 4.5, greater than 5, or greater than 5.5. In more particular embodiments, the perfume composition contains at least one ingredient meeting both contributions, and more particularly still the composition contains at least one ingredient meeting both contributions and having a molecular weight Mw of 200 g/mol or higher.

In certain embodiments of the present invention, perfume compositions useful in laundry care products according to the invention include independently at least 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12 , 13, 14, 15, 16, 17, 18, 19, 20, 21 , 22, 23, 24 or 25 or more perfume ingredients that meet the ClogP contribution referred to above, and/or at least 1 , 2, 3, 4, 5, 6, 7, 8, 9, 10, 11 , 12 , 13, 14, 15, 16, 17, 18, 19, 20, 21 , 22, 23, 24 or 25 or more perfume ingredients that meet the Affinity Factor contribution referred to above, it being understood that such perfume ingredients may fulfil one or both of the ClogP and Affinity Factor contributions.

The perfume ingredients referred to herein above, may represent the total perfume ingredient content in the perfume composition, or they may form only part of the perfume composition, in which case the perfume composition comprises other perfume ingredients that do not comply with the ClogP and Affinity Factor contributions, but which nevertheless are used by the skilled perfumer to complement the total perfume composition having regard to the particular hedonic or functional effect that is desired to be achieved.

In particular embodiments of the present invention the perfume ingredients conforming to one or both of the ClogP and Affinity Factor contributions represent 100 wt% of the total perfume composition, or less, for example, 90 wt% or less, 80 wt% or less, 70 wt% or less, 60 wt% or less, 50 wt% or less, 40 wt% or less, 30 wt% or less, 20 wt% or less, 10 wt % or less, 5 wt% or less, 2 wt% or less, or 1 wt% or less of the total pefume composition employed in the present invention. It being understood that when calculating the number of perfume ingredients in a perfume composition, or their percentage contribution to the total perfume composition, for any given perfume ingredient, if it satisfies both the ClogP and Affinity Factor contribution, its contribution (both number and percentage) is nevertheless only counted once.

The perfume composition useful in the present invention may be employed at a level selected by a skilled person to create a desired hedonic and/or functional effect. Typically, however, this might be in the range of 0.05 to 10 wt%, more particular 0.05 to 2.5 wt%, more particularly from 0.1 to 1.5 wt.-%, still more particularly from 0.2 to 1 wt.-%, based on the weight of the laundry care product.

Some or all of the perfume ingredients of the perfume composition employed in the laundry care product according to the invention may be encapsulated. Any media useful in the encapsulation of perfume compositions described in the art, may be employed in the present invention. Non-limiting examples of encapsulating media useful in the present invention are disclosed in the following prior art references: US 2003/215417; US 2003/216488; US 2003/158344; US 2003/165692; US 2004/071742; US 2004/071746; US 2004/072719; US 2004/072720; EP 1 ,393,706; US 2003/203829; US 2003/195133; US 2004/087477; US 2004/0106536; US 6,645,479; and US 6,200,949.

Encapsulated perfume compositions may be prepared using a range of conventional methods known to those skilled in the art for making shell capsules, such as interfacial polymerization, and polycondensation. Non-limiting examples of materials suitable for making shell of the microcapsule include urea-formaldehyde, melamine-formaldehyde, phenol-formaldehyde, gelatin, polyurethane, polyamides and the like.

Cationic surfactants present in laundry care products of the present invention are derived from non-renewable petrochemical resources. Accordingly, another advantage of the present invention resides in the discovery that the laundry care products can be rendered more sustainable by reducing the cationic surfactant load. The inventors achieved this by with the addition of a cellulase enzyme.

In contrast to many cationic surfactants used in laundry care products, cellulase enzymes can be obtained from renewable agricultural sources, naturally found in the environment and readily biodegradable. The replacement of cationic surfactants by cellulase enzymes addresses the United Nations’ Sustainable Development Goals, in particular Goal 12 “Responsible consumption and production”: replacing cationic surfactants with cellulase enzymes allows the producer - and thus the end user - to move from a potential fossil feedstock to a renewable feedstock and reduce the volume of persistent chemicals emitted to the environment.

Enzymes useful in exercise of the present invention are cellulase enzymes, in particular the family of GH45 cellulase enzymes. It has not previously been shown that using a cellulase enzyme, such as a family of GH45 cellulase enzymes, together with selected perfume ingredients, can be employed to modulate the olfactive impression of a perfume composition deposited onto a textile from a laundry care product.

In one embodiment, the enzyme is a cellulase having at least 60% sequence identity to SEQ ID NO: 1 , SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, or SEQ ID NO: 8, SEQ ID NO: 9. SEQ ID NO: 10, or SEQ ID NO: 11.

The cellulase may be anyone having at least 60% sequence identity to SEQ ID NO: 1 , SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, or SEQ ID NO: 8, SEQ ID NO: 9. SEQ ID NO: 10, or SEQ ID NO: 11 , preferably the cellulase has at least 65%, such as 70%, such as 75%, such as 80%, such as 85%, such as 90%, such as 91 %, such as 92%, such as 93%, such as 94%, such as 95%, such as 96%, such as 97%, such as 98%, such as 99%, or such as 100%, sequence identity to SEQ ID NO: 1 , SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, or SEQ ID NO: 8, SEQ ID NO: 9. SEQ ID NO: 10, or SEQ ID NO: 11 , or a fragment of SEQ ID NO: 1 , SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, or SEQ ID NO: 8, SEQ ID NO: 9. SEQ ID NO: 10, or SEQ ID NO: 11 , having cellulase activity.

Further suitable cellulases include those of bacterial or fungal origin. Chemically modified or protein engineered mutants are included. Suitable cellulases include cellulases from the genera Bacillus, Pseudomonas, Humicola, Fusarium, Thielavia, Acremonium, e.g., the fungal cellulases produced from Humicola insolens, Myceliophthora thermophila and Fusarium oxysporum disclosed in US 4,435,307, US 5,648,263, US 5,691 ,178, US 5,776,757 and WO 89/09259.

Additional suitable cellulases are the alkaline or neutral cellulases having colour care benefits. Examples of such cellulases are cellulases described in EP 0 495 257, EP 0 531 372, WO 96/11262, WO 96/29397, WO 98/08940. Other examples are cellulase variants such as those described in WO 94/07998, EP 0 531 315, US 5,457,046, US 5,686,593, US 5,763,254, WO 95/24471 , WO 98/12307 and W099/001544.

Other cellulases are endo-beta-1 , 4-glucanase enzyme having a sequence of at least 97% identity to the amino acid sequence of position 1 to position 773 of SEQ ID NO:2 of WO 2002/099091 or a family 44 xyloglucanase, which a xyloglucanase enzyme having a sequence of at least 60% identity to positions 40-559 of SEQ ID NO: 2 of WO 2001/062903.

The second and third aspects of the invention relates to a method of creating, modifying, improving or augmenting the olfactive impression of one or more perfume ingredients of a perfume composition deposited on a textile, the method comprising the step of the simultaneous, sequential or separate treatment of the textile with a perfume composition as defined herein and a cellulase enzyme, as well as the use of perfume compositions and cellulase enzymes in such methods.

The method relies upon the selection of certain perfume ingredients based on one or both of the two contributions referred to herein above related to the ClogP and the Affinity Factor A of the ingredients. These contributions provide a useful tool for perfumers to create perfume compositions for use in laundry care products containing a cellulase enzyme, and particularly those products containing a reduced level of cationic surfactant. In such products, the perfumer can take advantage of observed synergies between cellulase enzymes and certain perfume ingredients by combining both the perfume and cellulase enzyme in the same product.

In an alternative embodiment, the perfume composition and the cellulase enzyme may be applied to a textile separately and sequentially from different laundry care products. In such embodiment of the present invention, a first laundry care product, such as a detergent or a fabric conditioner, may contain a cellulase enzyme and a perfume composition that has not been designed in accordance with the present invention, and a second laundry care product, such as a scent booster, may contain a perfume composition as defined herein that contains perfume ingredients designed to deliver an olfactive impression when delivered onto a textile that is compatible with the perfume of the first laundry care product.

Such an embodiment might be useful or desirable when the perfume employed in the first laundry care product delivers a desirable olfactive impression to a consumer when smelled “neat”, that is, when smelled from the bottle or when poured into a machine to start a wash cycle, but the perfume signal is subsequently distorted when deposited on textile treated with a cellulase enzyme during one or more wash cycles. In such cases, a perfume composition designed according to the invention in a second laundry care product can be used to balance the olfactive impression delivered onto textile by the first laundry care product, whilst retaining the neat perfume rendition of that first laundry care product.

Such second laundry care products, containing perfume compositions designed in accordance with the present invention and which may or may not contain cellulase enzymes form another aspect of the invention.

In particular embodiments of the various aspects of the invention, the olfactive impression created, modified, improved or augmented may be related to the delivery onto a treated textile of a fresh note, a floral note, a sweet note, a creamy note or an oriental note; and/or it is related to increased bloom intensity or room-filling intensity.

The invention will be further explained and illustrated with reference to the following non-limiting examples.

EXPERIMENTAL

Example 1 : Perfume

The perfume of Table 1 was prepared by mixing all perfume ingredients at the indicated levels.

Table 1 : Perfume composition

Example 2: Washing, rinsing and olfactive evaluation procedures

In a first step, two loads of cotton fabrics consisting of 5 small cotton terry towels, 5 t-shirts 95% cotton 15% Lycra and 5 t-shirts 100% cotton were subjected to 20 laundering cycles, using 65 g of an unperfumed generic liguid high duty laundry care detergent, for 45 minutes at a temperature of 40°C. The loads were dried each time in a tumble dryer operating at 70 °C. The aim of this step was to age the fabric.

In a second step, each load was subjected to an additional 20 laundering cycles, including this time a rinsing cycle with an unperfumed dilute fabric conditioner having a dry matter content of 4.54 wt.-%, based on the total weight of the conditioner. In one load (A), the conditioner was used as such, whereas in the other load (B), 0.1 wt.-% of cellulase was added, based on the total weight of the conditioner. The aim of this step was to prepare two batches of cotton fabric, one having undergone a conventional laundering history, the other having undergone an enzymatic treatment.

For perfume ingredient deposition studies, 0.7 parts of the perfume of Table 1 was admixed with 99.3 parts of the dilute, unperfumed laundry care liguid conditioner. The mixture was allowed to macerate for 3 days before further use. Lot A was laundered again with no cellulase added to the conditioner, whereas Lot B was also laundered again, but with a conditioner comprising 0.1 wt % of cellulase having SEQ ID NO: 4, based on the total weight of the conditioner.

Both wash and rinse cycles were performed in a European front-loaded wash machine. The wash and rinse cycles were carried out during 50 minutes at 40 °C, followed by spin drying at 1000 rpm.

For the evaluation of the bloom “out of the machine", the machine was disposed in a 10 m ³ booth with an air flow of 25 air exchanges per hour. The panelists were instructed to enter the booth in pairs and one panelist to open the machine door. The panelists stand back against the booth door and the intensity of the odor at this location was assessed at the moment the odor was first detected.

For the evaluation of the “room filling" intensity, the washed fabrics were immediately transferred to a line drying set-up disposed in the booth. The air exchange was stopped and the fabric let for drying for 30 minutes. The panelists were instructed to assess through the porthole of the booth.

The olfactive evaluation was performed by a panel of 5 expert panelists.

The odor intensity was scored on a scale of 1-5 (1 = barely noticeable, 2 = weak, 3 = medium, 4 = strong and 5 = very strong). Simultaneously, qualitative description of the odor was recorded. These results are reported on Table 2.

Table 2: Perfume performance assessment

As is apparent from Table 2, the presence of the enzyme enhances the perception of the perfume and reinforce the caring impression of the conditioner. The significant increases of bloom and room filling intensity observed in the presence of the enzyme confirms that high performance perfume ingredients deposit better onto a cotton surface treated with cellulase.

Example 3: Measuring the deposition of perfume oil on textile

The analytical measurement was performed on the 100% terry towels. Pentane extraction was performed with a Speed Extractor (Buchi) to measure the perfume deposition on the garments. A known amount of material from the washed garments was placed in the SpeedExtractor. The solvent (pentane) under pressure was used to extract the material. Methyl decanoate (50pL of 10000ppm solution or 0.5mg) was used as internal standard.

Extracted samples were injected according to the “Splitless” Method in a GC/MS/FID (Agilent GC 7890A - MS5975C) for perfume identification and quantification with the internal standard.

Table 3 shows the amount of perfume ingredients deposited on the fabric of loads A and B:

Table 3: Deposition of perfume ingredients. (*) Deposition enhancement confirmed by olfactive evaluation.

The results of Table 3 demonstrate that there is a significant increase in deposition of perfume oil on textile as a result of the use of a cellulase enzyme for perfume ingredients having ClogP higher than 4, except for diphenyl oxide and aldehyde C 12 MNA. However, these discrepancies are attributed to analytical experimental issues related to the very high volatility of these ingredients. Olfactive evaluation confirms the better rendition of the fresh amber odor of ALDEHYDE C 12 MNA and long-lasting floral-rosy odor od DIPHENYL OXIDE on dry fabric treated with cellulase.
