Description

A COSMETIC COMPOSITION COMPRISING AT LEAST ONE ELASTOMERIC ANIONIC POLYURETHANE AND AT LEAST ONE NON-IONIC THICKENER

FIELD OF THE INVENTION

[001] The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one elastomeric film-forming polymer. It also relates to the use of this composition for the formulation of products for shaping, conditioning or care of the hair, for example, for the formulation of hair-styling products. [002] The present disclosure also relates to a method of conditioning, shaping or caring of the hair using this composition.

[003] Fixing of the hairstyle is an important element of styling, and involves the maintenance of shape. According to the present disclosure, the term "styling composition" refers to any type of hair-dressing composition that can be used for effecting styling.

TECHNOLOGICAL BACKGROUND

[004] Among the hair care products for hair fixing that are most widely available on the cosmetics market, mention may be made of spray compositions in aerosols or pump-action bottles such as lacquers, sprays or mousses, essentially constituted of a solution that is generally alcoholic or aqueous-alcoholic and of a film-forming polymer that is water-soluble or alcohol-soluble, mixed with various cosmetic additives, or alternatively mention may be made of products that are to be applied by hand, such as gels and waxes.

[005] However, these hair styling formulations, such as the aerosol sprays and lacquers may not always give the hairstyle satisfactory resistance to the various natural everyday movements such as walking, movements of the head or gusts of wind. Moreover, these compositions may give the hair a sensation of stiffness, the so-called "helmet effect". Styling products also include the styling shampoos, which offer the advantage of combining washing of the hair while permitting shaping of the hair during drying, saving time for the increasingly busy user. [006] The polymers used conventionally for the formulation of hair styling products are cationic, anionic, amphoteric or non-ionic film-forming polymers, which may lead to the formation of films that are hard and brittle to a varying degree.

[007] When the polymer is too brittle, the percentage elongation at break measured on the film is low, i.e. generally less than 2%, and the hairstyle is not long- lasting.

[008] To overcome this problem, these polymers have already been mixed with plasticizers, obtaining films that are more flexible and are not brittle. These films are deformable and plastic, and after deformation, they only regain their initial form to a slight extent. Although the lasting properties of the hairstyle are improved, they still may not be satisfactory, since the form of the hairstyle changes, under the action of the stresses.

[009] Therefore cosmetic compositions are being sought for the care and/or fixing of the hairstyle which give the hair, in addition to long-lasting fixing, good cosmetic properties, notably conditioning of the hair conferring good disentangling, softness and a pleasant, non-sticky appearance, as well as ease of use and low risk in use.

[010] One approach for achieving this objective is polyurethane technology. The polyurethanes have a characteristic of being very elastic and therefore of forming a stretchable film, which can withstand mechanical stresses. On the hair, this can translate into the formation of a homogeneous, non-brittle sheathing along the fibre. [011] The problems associated with this polyurethane technology are that the polyurethanes are very hydrophobic and therefore are not dispersible as such in water, or they are often in the form of opaque white latices. In this case, when included in any cosmetic formula, on application there may be formation of a white deposit on the hair, which is unacceptable for the consumer. In contrast to the conventional polyurethanes, the polyurethanes according to the present disclosure are dispersible in water, giving clear or translucent solutions.

[012] However, certain polyurethanes are non-thickening. In this case they may be combined with thickening polymers in the formulations so that they can be manipulated easily and deposited on the hair without running.

[013] The use of water-soluble or water-dispersible polymers as thickening agent for aqueous media, and optionally crosslinked polymers such as polycarboxyvinylic acids and CARBOPOL® Polymers, said polymers having a considerable chain length and a high molecular weight, is known. [014] Now, in certain cases, the anionic thickeners are incompatible with the polyurethanes, and may lead to compositions that are unsatisfactory for the consumer.

[015] It was discovered, unexpectedly, that by combining particular anionic polyurethanes with non-ionic thickeners it can be possible to obtain thickened compositions, such as gels, that are translucent, or even transparent, having sufficient viscosity and an appearance that is satisfactory for the consumer, while solving at least one of the drawbacks listed above. When applied to the hair, these thickened compositions lead to flexible, long-lasting fixing.

DESCRIPTION OF THE INVENTION

[016] The present disclosure relates to a cosmetic composition comprising, in a cosmetically acceptable medium, at least one elastomeric anionic film-forming polyurethane (A) and at least one non-ionic thickening polymer, wherein the at least one elastomeric anionic film-forming polyurethane (A) comprises:

(i) at least one side chain comprising at least one ethylene oxide unit, wherein the at least one side chain - represents from 12 to 80% by weight of polyurethane (A), and

- has a molecular weight ranging from 1000 g/mol to 30,000 g/mol; and (ii) one main chain comprising units derived from:

- a polypropylene glycol (PPG) and optionally a second non-ionic polyol,

- a dihydroxy-carboxylic acid, and - at least one di-isocyanate; and optionally

- a chain extender organic polyamine comprising an average of at least two primary amine groups.

[017] This composition may be used to obtain a flexible, non-brittle film on human keratinous fibers, which may allow the human keratinous fibers to move perfectly.

[018] In addition, the composition according to the present disclosure may be used for conditioning the human keratinous fibers.

[019] Another aspect of the present disclosure relates to a method of shaping or maintaining the hairstyle comprising applying the disclosed composition to human keratinous fibers.

DETAILED DESCRIPTION OF THE EMBODIMENTS OF THE INVENTION THE CHEMISTRY OF FILM-FORMING ELASTOMERIC POLYURETHANE [020] The at least one elastomeric anionic film-forming polyurethane (A) may be prepared according to the method described in International Patent Application Publication Nos: WO2006/124250 and WO03/087183. [021] In at least one embodiment, the at least one elastomeric anionic film- forming polyurethane (A) comprises

(i) at least one side chain comprising at least one ethylene oxide unit, wherein the at least one side chain

- represents from 12 to 80% by weight of polyurethane (A), and - has a molecular weight ranging from 1000 g/mol to 30,000 g/mol; and

(ii) one main chain comprising units derived from:

- a polypropylene glycol (PPG) and optionally a second non-ionic polyol,

- a dihydroxy-carboxylic acid such as a dimethylolpropionic acid (DMPA),

- at least one di-isocyanate, for instance, a isophorone diisocyanate; and - a chain extender organic polyamine having an average of at least 2 primary amine groups.

[022] The at least one elastomeric anionic film-forming polyurethane (A) is soluble or dispersible, either in an aqueous medium (100% water), or in a water/ethanol solvent mixture containing at most 30 wt.% of ethanol. For example, at least 10 g of polymer (A) is soluble or dispersible in 90 grams of water or of water/ethanol mixture.

[023] The at least one elastomeric anionic film-forming polyurethane (A) can be partially or totally neutralized or over-neutralized with inorganic or organic bases, for instance, with soda and/or triethylamine, in an amount making it possible to obtain, for example, a degree of neutralization of the anionic functions of the polymer ranging from 0 to 150%, such as ranging from 50 to 100%. The "degree of neutralization to 150%" is obtained with an amount of inorganic or organic base equal to 1.5 times the amount of base required to obtain the degree of neutralization to 100%.

[024] The result of this is that the at least one elastomeric anionic film-forming polyurethane (A) is a salt composed of two parts: one anionic polyurethane and a cationic ion, metallic or organic.

MECHANICAL PROFILE OF THE FILM-FORMING ELASTOMERIC POLYURETHANE

[025] In at least one embodiment, in the compositions according to the present disclosure, the film obtained by drying the at least one elastomeric anionic film-forming polyurethane (A) at room temperature (24°C ± 2°C) and at a relative humidity of 48% ± 5%, has a mechanical profile comprising:

(a) an elongation at break (ε_b) greater than or equal to 730% ± 5 % (e.g. - 5% of 730% represents 694%).

(b) an instantaneous recovery (R₁) greater than or equal to 70% ± 5%, after elongation of 150%; and

(c) a recovery (R300) at 300 seconds greater than 80% ± 5%. MEASUREMENT OF THE PARAMETERS

[026] For the purpose of the present disclosure, the expression, "film obtained by drying at room temperature (24°C ± 2°C) and at a relative humidity of 48% ± 5%" means the film obtained, in these conditions, from a mixture comprising 6% of active substance (a.s.) of the elastomeric anionic film-forming polyurethane (A), in a solvent (S). The amount of active substance is understood as being relative to the total weight of solvent (S) and the amount of mixture is suitable for obtaining, in a Teflon matrix, a film with thickness of 500 μm ± 50 μm, after drying the mixture, said drying being continued until there is no longer any change in weight of the film, which represents approximately 10 days.

[027] The solvent (S) is a mixture ethanol/water comprising less than 30 % by weight of water. [028] For the purpose of the present disclosure, the expression "elongation at break" and the "degree of recovery" are evaluated via the tests described below.

[029] To measure the instantaneous recovery and the recovery at 300 seconds, the polymer film obtained is cut into test pieces of rectangular shape, 80 mm long and 15 mm wide. [030] To measure the elongation, the polymer film obtained is cut into dumbbell- shaped test pieces.

[031] The tests are performed on apparatus marketed under the name LLOYD or marketed under the name ZWICK in the same conditions of temperature and of humidity as for drying, i.e. a temperature of 24°C ± 2°C and a relative humidity of 48% ± 5%.

[032] The test pieces are stretched at a speed of 20 mm/min and the distance between the jaws is 50 mm ± 1 mm.

[033] The elongation at break represents the ratio of the maximum elongation of the film before it breaks to its initial length measured before undergoing deformation. [034] The procedure for determining the instantaneous recovery (R₁) is as follows:

- stretch the test piece 150% (ε_max) i.e. 1.5 times its initial length (I₀),

- release the stress, imposing a return speed equal to the pulling speed, i.e.

20 mm/min, and measure the percentage elongation of the test piece, after returning to zero load (ε,). [035] The % instantaneous recovery (R₁) is given by the following formula:

Ri = ((εmax - ε,)/ε_max) x 100

[036] To determine the recovery at 300 seconds, it is held at zero stress for an additional 300 seconds, the test piece having undergone the preceding operations, and its percentage elongation is measured (ε₃oo_s)-

[037] The recovery at 300 seconds as a percentage (R3oos) is given by the following formula:

R300S = ((ε_max - ε3oos)/ε_max) x 100

[038] In the compositions according to the present disclosure, the at least one elastomeric anionic film-forming polyurethane (A) may be present in a total amount ranging from 0.05 to 20 wt.%, for instance, ranging from 0.1 to 15 wt.% or ranging from 1 to 10 wt.% relative to the total weight of the composition.

NON-IONIC THICKENING POLYMER [039] According to the present disclosure, any type of non-ionic thickening polymer, whether associative or non-associative, can be used.

[040] In one embodiment, the at least one non-ionic thickening polymer is chosen from associative thickening polymers. They may include at least one hydrophilic sequence and at least one hydrophobic sequence. [041 ] The at least one hydrophobic sequence may be chosen from alkyl, alkenyl, alkaryl or aralkyl chains having from 8 to 30 carbon atoms.

[042] The at least one hydrophilic sequence may be chosen from polyethylene oxide, a polysaccharide, a polyamide such as polyacrylamide, a polyester and mixtures thereof, for example, a polyethylene oxide having from 2 to 500 mol of ethylene oxides. [043] The bond or bonds between hydrophilic sequence and hydrophobic sequence may be chosen from, without imposing any limitation, ester, ether, urea, amide, and urethane type and mixtures thereof.

1 ) Non-associative thickening polymer

[044] For the purpose of the present disclosure, the expression "non-associative polymer" means a polymer not containing simultaneously at least one C8-C30 fatty chain and at least one hydrophilic unit.

[045] The non-associative non-ionic polymers according to the present disclosure can be of natural or synthetic origin. [046] They may be selected from:

- non-ionic homopolymers and copolymers containing monomers with an ethylenic unsaturation of the ester and/or amide type,

- homo- or copolymers of vinyl pyrrolidone, - polysaccharides.

[054] The modified non-ionic guar gums may be modified with C₁-C₆ hydroxyalkyl groups. [055] Among the hydroxyalkyl groups, we may mention for example the hydroxymethyl, hydroxyethyl, hydroxypropyl and hydroxybutyl groups.

[056] These guar gums are well known to one of ordinary skill in the art and can, for example, be prepared by reacting the corresponding oxides of alkenes, for example propylene oxides, with guar gum so as to obtain a guar gum modified with hydroxypropyl groups.

[057] The degree of hydroxyalkylation, which corresponds to the number of molecules of alkylene oxide consumed by the number of free hydroxyl functions present on the guar gum, may range from 0.4 to 1.2. [058] These non-ionic guar gums, optionally modified with hydroxyalkyl groups, are for example sold under the trade names JAGUAR HP8, JAGUAR HP60 and JAGUAR HP120, JAGUAR DC 293 and JAGUAR HP 105 by the company RHODIA CHIMIE or under the name GALACTASOL 4H4FD2 by the company AQUALON.

[068] The polyether polyurethanes have at least two lipophilic hydrocarbon chains, having from 6 to 30 carbon atoms, separated by a hydrophilic sequence, and the hydrocarbon chains can be pendant chains or chains at the end of a hydrophilic sequence. For instance, it is possible for at least one pendant chains to be provided. Moreover, the polymer can have a hydrocarbon chain at one end or at both ends of a hydrophilic sequence.

[069] The polyether polyurethanes can be multiblock copolymers such as in the form of triblock copolymers. The hydrophobic sequences can be at each end of the chain (for example: triblock copolymer with central hydrophilic sequence) or distributed both at the ends and in the chain (multiblock copolymer, for example). These same polymers can also be as grafts or star-shaped.

[070] The non-ionic fatty-chain polyether polyurethanes may be triblock copolymers wherein the hydrophilic sequence is chosen from polyoxyethylenated chains having from 50 to 1000 oxyethylenated groups.
