VISCOELASTIC COSMETIC COMPOSITIONS

FIELD OF THE DISCLOSURE

The present disclosure relates to viscoelastic cosmetic compositions. The compositions exhibit unique viscoelastic foaming properties and are particularly useful as cleansing and shaving compositions. Methods for making and using the viscloelastic compositions are also described.

BACKGROUND

Surfactants are widely used in aqueous based personal care, household, and industrial products. They are typically used as wetting agents, detergents, and emulsifiers. In personal care cleansing products (e.g., shampoos, body washes, facial cleansers, liquid hand soaps, etc.) the surfactant is often the most important component because it provides many of the cleansing attributes of the composition.

Although in principle any surfactant class {e.g., cationic, anionic, nonionic, amphoteric) is suitable in cleansing or cleaning applications, in practice most personal care cleansers and household cleaning products are formulated with anionic surfactants or with a combination of an anionic surfactant as the primary detersive agent with one or more secondary surfactants selected from the other surfactant classes. Anionic surfactants are often used as detersive agents in cleansers and cleaning products because of their excellent cleaning and foaming properties. From the consumer's perspective, the amount and stability of the foam directly relates to the perceived cleaning efficiency of the composition. Generally speaking, the larger the volume of foam produced and the more stable the foam, the more efficient is the perceived cleaning action of the composition. This presents a potential problem in low-surfactant formulations, as foam volume tends to decrease with decreasing surfactant concentration.

Anionic surfactants, especially sulfate-based surfactants, are popular because of their effectiveness in cleansing. Nonetheless, over-use of these surfactants can cause needless drying to the face and scalp, and contribute to color fading and drying of hair. Cationic conditioning agents can provide conditioning benefits to the hair, which can compensate for the drying caused by anionic surfactants. Nonetheless, it is difficult to incorporate cationic conditioning agents into cleansing compositions comprising anionic surfactants. The cationic conditioning agents have a tendency to interact with the anionic surfactants to form water- insoluble complexes that prevent the respective components from functioning properly, and disrupt the stability of the compositions.

SUMMARY OF THE DISCLOSURE

The present disclosure relates to viscoelastic compositions for use as cosmetics. The compositions exhibit unique viscoelastic foaming properties and are particularly useful as cleansing and shaving compositions. Viscoelasticity is the property of materials that exhibit both viscous and elastic characteristics when undergoing deformation. Viscous materials resist shear flow and strain linearly with time when a stress is applied. Elastic materials strain when stretched and quickly return to their original state once the stress is removed. Viscoelastic materials have elements of both of these properties and, as such, exhibit time-dependent strain. Due to their viscoelastic properties, the compositions of the instant disclosure exhibit a unique "memory foam-like" behavior that consumers find especially distinctive.

The constituents of the compositions are also unique because fatty dialkylamine compounds (such as stearamidopropyl dimethylamine) are combined with anionic surfactants (such as anionic sulfate surfactants). Fatty dialkylamine compounds are not typically combined with anionic surfactants because they can negatively interact with one another to form a water-insoluble complex. It was discovered, however, that by combining the fatty dialkylamine compounds with one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids, the fatty dialkylamine compounds become "neutralized," and can successfully be combined with anionic surfactants to form a stable composition having both cleansing and foaming properties. After "neutralization," the fatty dialkylamine compounds exhibit a cationic charge and therefore have properties similar to a cationic surfactant. This allows the fatty dialkylamine compounds to provide conditioning and discipline benefits to the hair.

The compositions of the instant disclosure typically include: (a) water; (b) one or more surfactants; (c) one or more amino silicones; (d) one or more cationic conditioning agents; (e) one or more fatty dialkylamines; and (f) one or more non- polymeric, mono-, di-, and/or tri-carboxylic acids. With respect to the one or more surfactants, at least one anionic surfactant is typically included. One or more amphoteric surfactants are also useful in the compositions and may be combined with one or more anionic surfactants. For example, betaine surfactants are sometimes used and may be combined with one or more sulfate surfactants. Many fatty dialkylamines may be used in the compositions. In some cases, the fatty dialkylamines may be fatty dimethylamines. Non-limiting examples include dimethyl lauramine, dimethyl behenamine, dimethyl cocamine, dimethyl myristamine, dimethyl palmitamine, dimethyl stearamine, dimethyl tallowamine, dimethyl soyamine, and mixtures thereof. Fatty dialkylamines include fatty amidoamine compounds and their salts. Non-limiting examples include oleamidopropyl dimethylamine, stearamidopropyl dimethylamine, isostearamidopropyl dimethylamine, stearamidoethyl dimethylamine, lauramidopropyl dimethylamine, myristamidopropyl dimethylamine, behenamidopropyl dimethylamine, dilinoleamidopropyl dimethylamine, palmitamidopropyl dimethylamine, etc. In some cases the compositions of the instant disclosure include at least stearamidopropyl dimethylamine.

Non-polymeric, mono-, di-, and/or tri-carboxylic acids are used to "neutralize" the fatty dialkylamines. In some cases, the one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids include at least one dicarboxylic acid. Non- limiting examples include oxalic acid, malonic acid, malic acid, glutaric acid, citraconic acid, succinic acid, adipic acid, tartaric acid, fumaric acid, maleic acid, sebacic acid, azelaic acid, dodecanedioic acid, phthalic acid, isophthalic acid, terephthalic acid, 2,6-naphthalene dicarboxylic acid, and mixtures thereof. In particular, tartaric acid is useful, especially in combination with fatty dimethylamines such as, for example, stearamidopropyl dimethylamine.

Polyalkylene glycols can optionally be incorporated into the compositions of the instant disclosure. Examples of polyalkylene glycols include polyethylene glycols (PEGs) and polypropylene glycols (PPGs). In some cases, appropriate polyalkylene glycols are solid (or semi-solid) at 25°C. The optional addition of polyalkylene glycols does not materially influence the viscolastic properties of the compositions. Nonetheless, polyalkylene glycols can be used as an emollient and aqueous thicker. In some cases, the inclusion of polyalkylene glycols can be used to increase the firmness of the foam.

The compositions may be formulated into a variety of cosmetic compositions in which a creamy, foamed, viscoelastic texture is desired. For example, due to the use of certain anionic surfactants, the compositions are well suited for cleansing. Thus, the compositions may be cleansing compositions for the body, face, and/or hair. In particular, the instant disclosure relates to shampoo compositions. The addition of cationic conditioning agents provides conditioning benefits to the hair, which many consumers find desirable. The cleansing compositions may be applied to the body or hair and subsequently rinsed from the body or hair.

Shampoos according to the instant disclosure can be repeatedly used to cleanse hair without forming build-up on the hair. Instrumental testing revealed that after shampooing hair swatches multiple times (3 times), no build up on the hair swatches was detected. Furthermore, hair treated with the compositions was smooth to the touch, was supple, was easily untangles with the hands, and exhibited especially good manageability. These benefits are especially useful for individuals with curly hair.

Due to their unique foaming properties, the instant compositions are useful as shaving compositions, e.g., shaving creams, shaving foams, combination shaving and cleansing compositions, etc. Shaving compositions are applied to an area of the body comprising hair and removed from the body together with the hair by a blade, such as a razor, in methods for shaving or removing hair from the body.

The compositions may be formulated into a variety of cosmetic compositions in which a creamy, foamed, viscoelastic texture is desired. For example, due to the use of certain anionic surfactants, the compositions are well suited for cleansing. Thus, the compositions may be cleansing compositions for the body, face, and/or hair. In particular, the instant disclosure relates to shampoo compositions. The addition of cationic conditioning agents provides conditioning benefits to the hair, which many consumers find desirable. The cleansing compositions may be applied to the body or hair and subsequently rinsed from the body or hair.

Due to their unique foaming properties, the instant compositions are useful as shaving compositions, e.g., shaving creams, shaving foams, combination shaving and cleansing compositions, etc. The compositions may be applied to an area of the body comprising hair and removed from the body together with the hair by a blade, such as a razor, in methods for shaving or removing hair from the body.

In view of the unique properties of the instant compositions, the compositions are particularly well suited for use as a cleansing composition, a shaving cream, a body wash, a face wash, a shampoo, a conditioning shampoo, a hair treatment composition, and a hair conditioning composition.

The disclosure further relates to methods for making the cosmetic compositions of the instant disclosure. Typically, the methods involve neutralizing one or more fatty dialkylamines with one more non-polymeric, mono-, di-, and/or tricarboxylic acids, and then adding this mixture comprising the neutralized fatty dialkylamines to the remaining constituents of the cosmetic composition. One or more cationic conditioning agents may optionally be combined with the combination of the one or more fatty dialkylamines and the one more non-polymeric, mono-, di-, and/or tri-carboxylic acids prior to combination with the remaining components of the cosmetic composition. Additionally, the combination comprising the one or more fatty dialkylamines and the one more non-polymeric, mono-, di-, and/or tri-carboxylic acids may be heated prior to combination with the remaining components of the cosmetic composition. For example, the combination may be heated to a temperature of about 40°C to about 75°C, preferably about 50°C to about 70°C, or more preferably about 55°C to about 70°C. Furthermore, if a polyalkylene glycol is used in the composition, it can optionally be added to the combination of the one or more fatty dialkylamines and the one more non-polymeric, mono-, di-, and/or tricarboxylic acids, before this combination is added to the other components of the cosmetic composition.

Typically, one or more surfactants, one or more amino silicones, water, and optionally, one or more cationic conditioning agents are mixed separately from the neutralized fatty dialkylamines prior to combination with the neutralized fatty dialkylamines. After mixing with the neutralized fatty dialkylamines, in some instances, one or more surfactants (for example, one or more betaine surfactants) may be added and mixed. Finally, pH adjusters and/or viscosity modifiers may be incorporated into the final composition, as desired.

The compositions may be packaged in a variety of different containers, such as, for example, a ready-to-use container. Due to the compositions' somewhat thick and gel-like consistency, non-limiting examples of useful packaging include tubes, jars, caps, unit dose packages, and bottles, including squeezable tubes and bottles. The packaging may be configured so that it can be attached to a wall, such as a wall in a bathroom, including walls of a shower or tub. For example, the packaging can be a container that is configured to attach to a wall, such that when pressure is applied to the container, the composition contained therein is expelled from one or more openings in the bottom of the container. This type of packing and configuration is convenient for consumers.

More exhaustive but non-limiting lists of components useful in the cleansing compositions disclosed herein are provided below.

13, more preferably a number from 1 to 10 and most preferably a number from 0 to 8.

In general, the lower the number of carbon atoms in the R group of the phosphate esters, the more irritating to the skin and the less soluble in water the phosphate ester becomes.

The total amount of the mono-, di-, and/or tri-carboxylic acids can vary depending on the type of composition. For example a restructuring composition that is added to chemical treatment composition will typically have a higher amount of the one or more mono-, di-, and/or tri-carboxylic acids because the one more mono-, di-, and/or tri-carboxylic acids become more diluted when the restructuring composition is combined with a chemical treatment composition.

The total amount of mono-, di-, and/or tri-carboxylic acids in a restructuring composition is typically about 1 to about 50 wt.%, based on the total weight of the restructuring composition. In some cases, the total amount of the one or more mono-, di-, and/or tri-carboxylic acids in a restructuring composition is about 1 to about 40 wt.%, about 1 to about 30 wt.%, about 1 to about 25 wt.%, about 1 to about 20 wt.%, about 5 to about 50 wt.%, about 5 to about 40 wt.%, about 5 to about 30 wt.%, about 5 to about 25 wt.%, or about 5 to about 20 wt.%.

When mixed with a hair treatment composition or when the hair restructuring components are already formulated as part of a chemical hair treatment formulation, the total amount of mono-, di-, and/or tri-carboxylic acids will typically be less than the total amount in a restructuring composition. For example, the total amount of mono-, di-, and/or tri-carboxylic acids in a chemical hair treatment composition may be about 0.01 to about 10 wt.%, about 0.01 to about 5 wt.%, about 0.01 to about 4 wt.%, about 0.01 to about 3 wt.%, about 0.1 to about 10 wt.%, about 0.1 to about 5 wt.%, about 0.1 to about 4 wt.%, about 0.1 to about 3 wt.%, about 0.5 to about 4 wt.%, or about 0.5 to about 3 wt.%, based on the total weight of the chemical hair treatment composition.

POLYALKYLENE GLYCOLS

Examples of polyalkylene glycols include polyethylene glycols (PEGs) and polypropylene glycols (PPGs). A general formula for polyalkylene glycols follows: H(OR)nOH, wherein R is an alkyl group and n>10. A general formula for polyethylene glycols is H(OCH2CH2)nOH, wherein n is >2. A general formula for polypropylene glycol is H(OCH2CH2CH2)nOH, wherein n is >2. Block polymers of polyalkylene glycols, and more particularly, block polymers of polyethylene glycol and polypropylene glycols may be used. Even more particularly, polyethylene-90 or polyethylene-180 may commonly be used. Polyoxyethylene glycols can also be employed.

Solid polyethylene glycols, polypropylene glycols and derivatives thereof are solid (or semi-solid) at 25°C and may be used. The solid polyethylene glycols are typically made from at least 16 units of ethylene glycol and have the general formula HO-(CH2-O-CH2-O) _y ~H with y being a number of at least 16, e.g. from 20 to 220 or from 40 to 150. The molecular weight (weight average) is above 720, e.g. from 720 to 100000, or from 950 or 1500 or 2000 or 2700 to 30000. Non- limiting examples of solid polyethylene glycols include PEG-20, PEG-32, PEG-40, PEG-45, PEG-55, PEG-60, PEG-75, PEG-90 and PEG-100. Suitable trade products are for example Polyglykol 3000 of Clariant with an average molecular weight of 2700 to 3000 or Polyglykol 4000 with an average molecular weight of 3700 to 4500.

THICKENING AGENTS

Consumers expect of their cleansing products have an aesthetically pleasing viscosity. Formulations that flow with a watery consistency are aesthetically unpopular to consumers with expectations of rich and creamy products. While low viscosity products may be effective for their intended purpose, they are perceived to be of low quality by the consumer. Formulations that flow with a watery consistency run off when applied.

As used herein, the term "thickening agent" means compounds which, by their presence, increase the viscosity of the composition into which they are introduced. For examples, the viscosity may be measured using a cone/plate viscometer, a Haake R600 rheometer, or the like. The thickening agent may be referred to interchangeably herein as thickener or rheology modifier. Thickening agents are also sometimes referred to as gellifying agents and/or viscosity modifying agents.

In certain embodiments, the thickening agent may be chosen from those conventionally used in cosmetics, such as polymers of natural origin and synthetic polymers, for example, nonionic, anionic, cationic, amphiphilic, or amphoteric polymers, and other known rheology modifiers, such as cellulose-based thickeners.

Many thickeners are water-soluble, and increase the viscosity of water or form an aqueous gel when the cosmetic composition of the invention is dispersed/dissolved in water. The aqueous solution may be heated and cooled, or neutralized, for forming the gel, if necessary. The thickener may be dispersed/dissolved in an aqueous solvent that is soluble in water, e.g., ethyl alcohol when it is dispersed/dissolved in water.

In some cases, the thickening agents can be anionic thickening agents. Anionic thickening agents may be chosen from hydrophilic thickeners. Non-limiting examples of hydrophilic thickeners include homopolymers or copolymers of acrylic or methacrylic acids or the salts thereof and the esters thereof, such as those sold under the tradenames Versicol F® or Versicol K® by the company Allied Colloid, or under the tradename Ultrahold 8® by the company Ciba-Geigy; polyacrylates and polymethacrylates such as copolymers of (meth)acrylic acid, copolymers of (meth)acrylic acid, methylacrylate and dimethyl meta-isopropenyl benzyl isocyanate of ethoxylated alcohols such as methylacrylate and dimethyl meta-isopropenyl benzyl isocyanate of ethoxylated alcohol (INCI name: Polyacrylate-3) sold under the tradename Viscophobe® DB 1000 from The Dow Chemical Company, those sold under the tradenames Lubrajel and Norgel by the company Guardian, or under the tradename Hispajel by the company Hispano Chimica; and polyacrylic acids of Synthalen® K type, copolymers of acrylic acid and of acrylamide sold in the form of the sodium salt thereof, such as those sold under the tradenames Reten® by Hercules, sodium polymethacrylate such as those sold under the tradename Darvan® 7 by the company Vanderbilt, and the sodium salts of polyhydroxycarboxylic acids such as those sold under the tradename Hydagen F® by the company Henkel, and polyacrylic acid/alkyl acrylate copolymers of PemulenTM type.

In certain cases, the at least one thickening agent is chosen from copolymers resulting from the polymerization of at least one monomer (a) chosen from carboxylic acids possessing α,β-ethylenically unsaturated groups or their esters, with at least one monomer (b) possessing ethylenically unsaturated groups and comprising a hydrophobic group.

The thickening agents may also be chosen from hydrophilic thickeners, for example cellulose polymers and gums, modified or unmodified carboxyvinyl polymers, such as those sold under the tradename Carbopol® (CTFA name: carbomer) by the company Goodrich, polyacrylamides, copolymers of acrylic acid and of acrylamide sold in the form of the sodium salt thereof, such as those sold under the tradenames Reten® by Hercules, and the sodium salts of polyhydroxycarboxylic acids such as those sold under the tradename Hydagen F® by the company Henkel, optionally crosslinked and/or neutralized 2-acrylamido-2- methylpropanesulphonic acid polymers and copolymers, for instance poly(2- acrylamido-2-methylpropanesulphonic acid) such as those sold under the tradename Hostacerin® AMPS (CTFA name: ammonium polyacryldimethyltauramide) by the company Clariant, crosslinked anionic copolymers of acrylamide and of AMPS, e.g. in the form of a water-in-oil emulsion, such as those sold under the tradename Simugel™ 600 (CTFA name: Acrylamide/Sodium acryloyldimethyltaurate copolymer/lsohexadecane/Polysorbate 80) by the company Seppic, polyacrylic acid/alkyl acrylate copolymers of PemulenTM type, and mixtures thereof.

In some cases, the thickening agent may be chosen from nonionic homopolymers or copolymers containing ethylenically unsaturated monomers of the amide type, for example, the polyacrylamide products sold under the tradenames Cyanamer® P250 by the company CYTEC.

The thickening agents may be chosen from polymers of natural origin and may include thickening polymers comprising at least one sugar unit, for instance nonionic guar gums, optionally modified with C1 -C6 hydroxyalkyl groups; biopolysaccharide gums of microbial origin, such as scleroglucan gum (also known as sclerotium gum) or xanthan gum; gums derived from plant exudates, such as gum arabic, ghatti gum, karaya gum, gum tragacanth, carrageenan gum, agar gum, carob gum, ceratonia siliqua gum or cyamopsis tetragonoloba (guar) gum; pectins; alginates; starches; hydroxy(C1 -C6)alkylcelluloses; or carboxy(C1 -C6)alkylcelluloses.

Inventive formulations A and B were prepared by adding the polyquaternium-10 to water and mixing, followed by the addition and mixing of tartaric acid and stearamidopropyl dimethylamine. This combination was heated to 65 ^Q C and mixed until the solids were melted. After the heating was stopped, a quaternary ammonium compound(s) (e.g., Polyquaternium-7 and/or Polyquaternium-10) was added and mixed, followed by the addition of PEG-90M (for Formulation A).

In a separate container, carbomer was added to water and mixed until the solids were completely dispersed. Sodium laureth sulfate and sodium lauryl sulfate were then added and mixed. Subsequently, salicylic acid, sodium benzoate, and amodimethicone (provided by the supplier as a blend with small amounts of nonionic and cationic surfactants), and fragrance were added and mixed until solubilized. The first mixture comprising tartaric acid and the stearamidopropyl dimethylamine was combined with the second mixture comprising the anionic surfactants (sodium laureth sulfate and sodium lauryl sulfate). Finally, coco-betaine and other desired additives or miscellaneous ingredients such as sodium chloride, were added and mixed until solubilized. The final pH may be adjusted with an acid such as salicylic acid or additional amount of tartaric acid and/or sodium hydroxide, and the viscosity may be adjusted with sodium hydroxide and/or hexylene glycol.

Although the commercial benchmark (Formulation C) has slightly different amounts of sulfate surfactants and coco-betaine, and includes dimethicone instead of amodimethicone, these differences do not appreciably account for the difference in the compositions' properties, in particular the difference in the compositions' viscoelastic properties, rheology characteristics, and foam characteristics (which are described in more detail in the subsequent Examples). It has been surprisingly discovered that the combination of the fatty dialkylamine (stearamidopropyl dimethylamine) and the non-polymeric, mono-, di-, and/or tricarboxylic acid (tartaric acid) in Formulations A and B results is critical difference between these formulations and Formulation C. The tartaric acid neutralizes the stearamidopropyl dimethylamine. Without wishing to be bound by any particular theory, it is believed that the neutralized fatty dialkylamine behaves as a cationic surfactant that interacts with anionic surfactants to create a strong surfactant web that imparts the strong viscoelastic properties to the instant compositions. In addition, it is believed that the neutralization of the fatty dialkylamine enabled the inventors to prepare a stable composition that contains both a cationic surfactant and an anionic surfactant

Although salicylic acid is a mono-, di-, and/or tri-carboxylic acid, it was not actually used to "neutralize the" the stearamidopropyl dimethylamine. In the instant examples, it was added after the stearamidopropyl dimethylamine was neutralized, and used as a preservative. The neutralization step was carried out by adding the polyquaternium-10 to water and mixing, followed by the addition and mixing of tartaric acid and stearamidopropyl dimethylamine. The neutralization step is carried out at an acidic pH (below 7), for example, at a pH of about 2.5 to about 5, about 3 to about 4.5, or about 3 to about 3.5. After the neutralization step is complete, the pH can be raised as additional components of the formulation are combined.

Example 2

(Properties)

The physico-chemical properties of the inventive shampoos (Formulations A and B in Example 1 ) were characterized by rheological measurements. Foams generated from these shampoos were characterized by measurements of aeration rate, texturometry and binocular magnifier, and compared to a comparative commercial benchmark shampoo (Formulation C in Example 1 ). The rheological measurements show that the inventive shampoos (Formulations A and B) exhibit a pseudo-maxwellian behavior and have profiles of surfactant solutions (wormlike micelles) with a relaxation time much longer than the comparative commercial benchmark shampoo (7 times longer). From a rheological point of view, the addition of PEG-90M had no effect. The aeration rate measurements and binocular magnifier of the three shampoos were similar, however the firmness of the inventive shampoos were higher than the comparative commercial benchmark shampoo, with Inventive Formulation A (with PEG-90M) displaying higher firmness than Inventive Formulation B.

Rheology Characteristics

The rheological characteristics were measured using a MCR 502 from ANTON PAAR rotational rheometer, equipped with an air-cooled Peltier plate to regulate the temperature. A cone and plate geometry 50 mm / angle 1 ° (sandblasted stainless steel at 5 μιη) was used with anti-evaporation device to avoid evaporation during measurements. The rheology characteristics are shown by the viscoelastic spectrum from 0.1 to 100 Hz at 25.0°C (with a deformation of 0.1 %) in FIG. 1 and the flow curve from 0.1 to 1000s ¹ at 25.0°C in FIG. 2.

FIG. 1 shows that the three shampoos (Formulations A and B, and the comparative commercial benchmark (Formulation (C)) display similar typical behavior for pseudo-maxwellian fluids (elastic plateau of G' at high frequency, crossing point between G' and G", and liquid behavior at low frequency) which is the signature of wormlike micelles. The two inventive shampoos (Formulations A and B) present a similar profile and a similar, very high relaxation time, which was 7 times longer than the comparative commercial benchmark shampoo. The viscoelastic moduli G' and G" of viscoelastic inventive shampoos are higher too. Note that the viscoelastic spectra do not detect the presence of polymer PEG-90M, which indicates that the PEG-90M does not influence the viscoelastic properties of the compositions. A comparison of the viscoelastric spectra show that the inventive shampoos (Formulations A and B) exhibit significantly more viscoelastic (memory-foam-like) behavior than the commercial benchmark. This is shown by the longer, extended plateau of the lines for Formulations A and B. The lines representing Formulations A and B have an early onset of the plateau and have an overall more "flat" profile than the commercial benchmark shampoo.

FIG. 2 shows that all three shampoos (Formulations A and B, and the comparative commercial benchmark) reach a pseudo-Newtonian plateau at low shear rate (wormlike micelles). The slipping transition of the inventive shampoos (Formulations A and B), due to the alignment of the micelles, occurs at much lower values of shear rate in comparison to the comparative commercial benchmark shampoo.

Foam Characteristics

Foams were generated from all shampoos listed in Example 1 (Formulations A, B, and C) that had been diluted three times with tap water. Samples were foamed in a 500 ml plastic beaker using a Philips hand blender (700 watt) equipped with a whisk. This blender has 5 speed levels; speed #2 was used. The samples were whipped for two minutes to generate foam.

A polycarbonate cylinder (height 70 mm and diameter 50 mm), was filled with the foam and weighed. The air fraction φ is expressed as percent, as follows:

where mt is the mass of foam in grams and m _w is the mass of the same volume of water. To determine m _w , prior to the experiment the crystallizer was weighted once empty and once filled with water. Densities of the diluted shampoos are assumed to be the same as the density of tap water for this analysis. The aeration rate for Formulation A, B, and C are shown in FIG. 3. The aeration rate represents the volume fraction of air in the foam. Values reported are mean values calculated for two replicates and error bars correspond to standard deviation. The inventive viscoelactic shampoos (Formulations A and B) display similar values for aeration rate, which are similar to the aeration rate for the comparative commercial benchmark formulation (Formulation C).

Foam texture is analyzed with a Stable Micro System TA.XT.plus texture analyzer equipped with a force sensor able to detect forces up to 50 N. The probe used is a polycarbonate disk of thickness 5 mm and diameter 45 mm. It is connected to the force sensor with a metal rod. The foam container is a polycarbonate cylinder of height 70 mm and diameter 50 mm. A force is measured versus time during back-extrusion: the probe gets through the foam and gets out of the foam. The parameters used are as follows: velocity of the probe is 40 mm/s before, during and after penetration, and penetration depth is 40 mm. The graph force versus time allows extracting parameters of interest: the firmness corresponds to the highest force value measured during penetration of the probe. Firmness of foams generated with the Philips hand blender from viscoelastic shampoo formulae are plotted in FIG. 4. It corresponds to average values calculated for two replicates and error bars are standard deviation. Formulation B displays lower firmness than Formulation A (with PEG-90M). Both inventive shampoos (Formulations A and B) presented higher firmness than the comparative commercial benchmark shampoo (Formulation C).
