Description:
FRAGRANCE COMPOSITION

FIELD OF THE INVENTION

The invention is directed to an ethanol-free fragrance composition. The composition can be in concentrated and ready-to-use (RTU) forms.

All publications, patents, patent applications, and other references cited in this application are incorporated herein by reference in their entirety for all purposes and to the same extent as if each individual publication, patent, patent application or other reference was specifically and individually indicated to be incorporated by reference in its entirety for all purposes. Citation of a reference herein shall not be construed as an admission that such is prior art to the present invention.

BACKGROUND OF THE INVENTION

Fragrance compositions typically use an alcohol, such as ethanol, as a solvent because the fragrance component, such as an essential oil, dissolve well in alcohol. But ethanol is a harsh chemical and classified as a volatile organic compound ("VOC"); a compound defined, for example, by the Environmental Protection Agency, or by EC Directive 1999/13/EC (Solvent Emissions Directive) as an organic compound having a vapour pressure of 0.01 kPa or more at 293.15 K (20°C), or having a corresponding volatility under particular conditions of use.

The replacement of ethanol is very challenging for the perfumer due to the beneficial attributes of this ingredient in perfume formulations. Indeed ethanol is an ideal solvent for perfumery ingredients, e.g. it evaporates rapidly and does not hedonically interfere with the odor of the perfume in applications. Another key characteristic of ethanol is its wetting power, which allows good spreadability of the perfume on the skin and in turn controls the diffusion of the perfume at a later step. The fast evaporation of ethanol also adds a somewhat refreshing aspect to the formulation; a characteristic that is highly appreciated by the customer.

Water-based fragrance formulations are an alternative to ethanol-based compositions. But water-based formulations also suffer from a number of disadvantages. These disadvantages include, for example, restrictions in fragrance creation due to water solubility issues of perfuming ingredients; limitations on the amount of fragrance that can be employed due to fragrance solubility or solubilization issues; the need of large amounts of solubilizers and surfactants that raise safety, environmental and regulatory issues; undesirable skin feel such as tackiness and oilyness; unacceptable fragrance performance such as spray atomization or diffusion through delivery devices such as wicks or reeds; and surface staining upon application.

Therefore, a need exists in the art for novel, ethanol-free fragrance formulations that are sustainable, non-irritating, cost-effective, and formulated without the need of external mixing forces to disperse or dissolve the fragrance in the formulation, such as high shear, high pressure or phase inversion temperature (PIT).

SUMMARY OF THE INVENTION

The present invention is directed to an ethanol-free fragrance composition, comprising:

A. 0.1% to 95% by weight fragrance selected from the group consisting of fragrance ingredients, flavor ingredients, essential oils, natural extracts, or a mixture thereof, and optionally fragrance miscible or partial miscible cosmetic ingredients selected from the group consisting of emollients, humectants, cooling agents, vitamins, antioxidants, dyes, pigments, preservatives, UV-blockers and specialty ingredients selected from the group consisting of malodor counteracting ingredients or insect repelling agents;

B. a phase transfer carrier at a weight ratio of 1 :9 to 1 : 1 versus total amount of fragrance and capable of self-segregating in water into organized clusters;

C. an ethanol-free water modulator at a weight concentration of 5-95% of said fragrance composition, comprising: (i) an interfacial modulator at weight ratio 1 :5 to 10: 1 versus total amount of fragrance, comprised of a miscible or partial miscible antimicrobial composition or a mixture thereof, and (ii) a water disrupting solvent at a weight concentration 10-90%o versus total amount of water modulator, comprised of one or more water miscible, or partial miscible, hydrotropic or hydrophilic solvent, or mixture of such solvents, having surface tension values less than 60 mN/m measured at 20-25°C and atmospheric pressure 760 mm Hg; and

D. optionally, up to 20% by weight water versus total amount of functional fragrance. The invention is also directed to consumer articles or products comprising the ethanol- free fragrance composition and methods of using the composition.

DETAILED DESCRIPTION OF THE INVENTION

The invention provides for an ethanol-free, clear or translucent, temperature stable, fragrance composition, alternative referred to herein as the "composition," "formulation" or the "functional fragrance." The inventors unexpectedly discovered that the functional fragrance (alternatively referred to herein as "fragrance," "parfume" or "perfume") in the composition self- transfers into water, either by direct dilution or by dispersion, through a dual solvency- solubilization mechanism without the need of applying external forces such as high shear mixing, high pressure, or PIT.

In an embodiment of the invention, the functional fragrance comprises (i) 0.1 to 95% by weight fragrance, also referred in the invention as perfume or parfume, which fragrance contains at least 0.1% by weight one or more fragrance ingredients, flavor ingredients, essential oils, natural extracts, or a mixture thereof, and optionally fragrance miscible cosmetic ingredients such as emollients, humectants, cooling agents, antioxidants, antibacterial agents, dyes, UV- blockers, or specialty ingredients such as malodor neutralizing, counteracting ingredients or insect repelling agents, (ii) a phase transfer carrier at a weight ratio 1 :9 to 1 :1 versus total amount of fragrance, (iii) an ethanol-free, water modulator at the weight concentration 5-95% versus fragrance composition, and (iv) optionally, up to 20% by weight water.

The aforementioned phase transfer carrier can include, for example, at least one, or more, associative ionic, non-ionic amphiphilic molecules, or a mixture thereof. The phase transfer carrier is capable of self-segregating in water into organized clusters or aggregates such as micelles or to self-structure into water-dispersible lamellar, cubical, or hexagonal crystal liquid morphologies.

The ethanol-free water modulator of the invention can be, for example, of two parts: (i) an interfacial modulator at a weight ratio 1 :5 to 10: 1 versus total amount of fragrance, which is a fragrance miscible or partial miscible antimicrobial composition, and (ii) a water disrupting solvent at a weight concentration of 1-95% versus total amount of water modulator, which is comprised of at least one or more, water miscible, or partial miscible, hydrotropic or hydrophilic solvent, or mixture of such solvents, having surface tension values less than 60 mN/m while, surface tension values measured under normal conditions, where herein normal conditions mean room temperature 20-25°C and atmospheric pressure 760 mm Hg.

The water-based products or articles created by the incorporation of the functional fragrance of the invention, also alternatively referred to herein as the "perfuming compositions", benefit from the presence of the interfacial modulator for at least two reasons: (i) unexpectedly, and surprisingly, the interfacial modulator allows for the lowering of the amount of the phase transfer carrier, while also allowing for the customization of the using level of fragrance into perfuming composition; and (ii) the perfuming compositions containing this interfacial modulator self-preserve in water, with no need to add extra antimicrobial agents.

Embodiments of the invention include, for example, any article or product associated with the functional fragrance, obtained by direct use of the said functional fragrance, or simply by dilution with water or dispersion in water. Other embodiments of the invention include methods of manufacturing such an article or product. Moreover, the functional fragrance of this invention can be directly diluted with water, or can be dispersed in water by gentle mixing, with no need to apply any external mixing force such as high pressure, high shear, or temperature phase inversion (PIT), to form a low viscosity, sprayable, or capillary wicking product or article.

The ethanol-free, self-water-transfer fragrance composition of the invention can be formulated under no restriction rules into skin, hair, home care and environmentally-safe products or articles, and allows the customization of the fragrance level in products or articles. A further feature of the present invention is that the herein protected functional fragrance has a high flash point, which makes it safe in handling and transportation; low viscosity; and excellent clarity and stability over wide temperature ranges. Further, the functional fragrance of the invention can accept certain amounts of functionalized oil- or water-soluble cosmetic ingredients, such as antioxidants, moisturizers, emollients, vitamins, UV stabilizers, dyes, or specialty ingredients such as malodor counteracting ingredients or insect or animal repelling agents. The perfuming products created based on the functional fragrance of this invention are safer, greener and have better performance characteristics than most petrochemical solvent based similar products or articles such as perfumes, cosmetic formulations, air fresheners, household products, I&I products. The instant invention is distinguishable over other formulations in the art because of at least two aspects: a formulation aspect and a processing aspect. The formulation aspect is related to the fragrance formulation strategy, which is a novel, two-part fragrance formulation strategy to build a self-water-transferable functional fragrance. The first part includes, for example, a fragrance oil and "phase transfer carrier", while the second part is comprised of a "water modulator". When the two parts are mixed together, the result is the functional fragrance. This fragrance formulation strategy leads to an unexpected dual solvency-solubilization mechanism which allows for the direct transfer of functional fragrance into water, to form a single-phase, isotropic, clear or translucent, temperature stable perfuming product or article, without the need to apply external mixing forces, such as high shear, high pressure or PIT. The processing aspect relates to the processing of the functional fragrance by direct dilution with water or by dispersion in water by gentle mixing with no need to apply external forces such as high shear, high pressure, and phase inversion temperature.

In one embodiment, a key element of the invention is the antimicrobial interfacial modulator. The antimicrobial modulator of the invention functions to: (i) formulate fragrances with unusual and unexpected properties when are transferred in water, and (ii) transfers fragrances in water, or to handle the fragrances and water mixing process in unusual and unexpected ways. By employing the antimicrobial modulator, the inventors were able to: (i) handle the fragrance as a fragrance "concentrate", referred to herein as a functional fragrance, which self-disperses in water or is a self-water dilutable fragrance; (ii) dilute the functional fragrance or disperse the functional fragrance in water to form a RTU clear or translucent, single- phase, temperature stable perfuming products or articles that display unusual low viscosity, sprayable, spreadable, skin feeling, skin benefits, hair deposition or capillary wicking properties with no need to apply external mixing forces such as high shear, high pressure or PIT; and (iii) reduce the level of phase transfer carrier needed to transfer the fragrance in water at desired and customized levels, with no ingredient restrictions in fragrance creation and limited restrictions in selection of optional fragrance miscible ingredients; (iv) formulate stable perfuming products or articles with no need to add extra antimicrobial agents.
