Patent Application
20060110353
Disclosed herein is a composition for cosmetic treatment of keratin materials, packaged in an aerosol device comprising (a) at least one propellant and (b) a hairstyling composition comprising at least one high molecular weight polyurethane in a cosmetically acceptable medium comprising water. Also disclosed herein is an aerosol device comprising at least one propellant and at least one high molecular weight polyurethane, and also to a method of styling the hair using such a device.
As used herein, a “high molecular weight polyurethane” is a polyurethane having a number-average molecular weight ranging from 400 000 to 5 000 000.
Hairstyling compositions packaged in the form of an aerosol spray generally contain a large alcohol fraction. Now, cosmetic products with a high alcohol content are subject to specific monitoring, especially in the United States, following the recent sensitization of public opinion to the ecological problems resulting from the emission of volatile organic products into the atmosphere.
One solution for decreasing the amount of alcohol is replacement with an equivalent amount of water. This introduction of large amounts of water into aerosol sprays intended for fixing the hair, such as lacquers, results, however, in a considerable unwanted deformation of the hair and in degradation of the cosmetic properties. Moreover, most propellants of hydrocarbon type are incompatible with water and their use in compositions with a high water content is, as a result, generally impossible. Once applied to the hair, the fixative compounds should allow the hair to be fixed.
The polymers presently in use as fixatives in styling compositions do not allow the shape of the hairstyle to be retained when it comes into contact with water for a prolonged period, such as, for example, when contacted with rain, perspiration, or during bathing: bathing in the sea or in a swimming pool.
Surprisingly, the inventors have discovered that the use of a cosmetic treatment composition packaged in an aerosol device comprising (a) at least one propellant and (b) a hairstyling composition comprising at least one polyurethane having a molecular number-average molecular weight ranging from 400 000 to 5 000 000, in a cosmetically acceptable medium comprising water, allows hairstyles to be fixed and shaped and also allows the shape of the hairstyles to be retained when they come into contact with liquid water for a prolonged period.
As used herein, this phenomenon is referred to as “water resistance”.
As used herein, “prolonged period” means contact with water for a minimum period of one minute, for example, 10 minutes and further, for example, 20 minutes.
The compositions disclosed herein also may make it possible to obtain a hairstyle resistant to atmospheric humidity.
The compositions disclosed herein may allow effective fixative and effective holding of the hair, in other words a styling effect that lasts throughout the day, or even for several days, which exhibits good water resistance, for example, resistance to repeated bathing, wherein these compositions may also be removed by shampooing.
The compositions disclosed herein also may make it possible to impart good cosmetic properties.
The present disclosure therefore provides a cosmetic treatment composition packaged in an aerosol device comprising (a) at least one propellant and (b) a hairstyling composition comprising at least one polyurethane having a number-average molecular weight ranging from 400 000 to 5 000 000, in a cosmetically acceptable medium comprising water.
Also disclosed herein is a method for styling the hair comprising spraying the mixture comprised in an aerosol device comprising a composition for cosmetic treatment of keratin materials, packaged in an aerosol device comprising (a) at least one propellant and (b) a hairstyling composition comprising at least one polyurethane having a number-average molecular weight ranging from 400 000 to 5 000 000 g/mol, in a cosmetically acceptable medium comprising water over the hair that has been shaped and in allowing the hair thus treated to dry.
Also disclosed herein is a process for treating the hair comprising spraying to said hair a mixture comprised in an aerosol device comprising a composition for cosmetic treatment of keratin materials, packaged in an aerosol device comprising (a) at least one propellant and (b) a hairstyling composition comprising at least one polyurethane having a number-average molecular weight ranging from 400 000 to 5 000 000 g/mol, in a cosmetically acceptable medium comprising water wherein the hair is fixed and shaped and retains the shape of hairstyles when said hair comes into contact with water for a prolonged period. According to this embodiment, the process for treating the hair comprising spraying the hair with a mixture comprised in an aerosol device comprising the composition as disclosed herein may make it possible to obtain a hairstyle (shaping of the hair) resistant to water.
Hairstyling Composition
As used herein, “polyurethane” means polycondensates comprising at least one polyurethane sequence. They are described, for example, in European Patent Nos. EP 0 751 162, EP 0 637 600, EP 0 656 021, EP 0 619 111 and EP 0 648 485, French Patent No. FR 2 743 297, and in PCT Publication No. WO 94/03510.
The polyurethanes disclosed herein may be soluble in the cosmetically acceptable aqueous medium, for example, after neutralization with an organic or inorganic base, or else may form a dispersion in said medium. In that case the dispersion may comprise at least 0.05% of surfactant, allowing the non-associative polyurethane to be dispersed and to be held in dispersion.
In one embodiment, the dispersion described herein may comprise a surfactant, for example, a nonionic surfactant. The average size of the particles of the non-associative polyurethane in the dispersion may range from 0.1 to 1 micrometer.
For example, the polyurethane may be formed by an arrangement of blocks, this arrangement being obtained, for example, from:
The at least one compound (1) may be chosen from diols, diamines, polyesterols, polyetherols and mixtures thereof.
The at least one compound (1) may be, for example, linear polyethylene glycols and polypropylene glycols, for example, those obtained by reacting ethylene oxide or propylene oxide with water or reacting diethylene or dipropylene glycol in the presence of sodium hydroxide as catalyst. These polyalkylene glycols generally have a molecular mass ranging from 600 to 20 000.

Polyhydric alcohols appropriate for preparing the polyesters include, for example, ethylene glycol, propylene 1,2-glycol, 1,4-butanediol, neopentyl glycol and hexanediol. It is also possible to use amino alcohols, for example ethanolamine. Appropriate diamines for preparing the amide-polyesters are ethylenediamine and hexamethylenediamine.
Appropriate polyacetals may be prepared, for example, from 1,4-butanediol or hexanediol and formaldehyde. Appropriate polythioethers may be prepared, for example, by a condensation reaction of thioglycols, alone or in combination with other glycols such as ethylene glycol, propylene 1,2-glycol or with other polyhydroxy compounds. Polyhydroxy compounds already comprising urethane groups, natural polyols, which may additionally be modified, for example castor oil and carbohydrates, may also be used.
For example, the at least one compound (1) may be a polyesterol, for example, a polyester-diol formed by the reaction of at least one (di)-polyol (1a) and at least one acid (1b).

For example, the at least one compound (2) is useful as a coupling block. The at least one compound (2) may include at least one poly(α,α-dihydroxy carboxylic acid).
The at least one compound (2) may be chosen from 2,2-di(hydroxymethyl)acetic acid, 2,2-dihydroxymethylpropionic acid, 2,2-dihydroxymethylbutyric acid and 2,2-dihydroxymethylpentanoic acid.

The polyurethane may be formed with the aid of at least one additional compound (4) serving generally to extend its chain. The at least one compound (4) may be selected, for example, from saturated or unsaturated glycols such as ethylene glycol, diethylene glycol, neopentyl glycol, and triethylene glycol; amino alcohols such as ethanolamine, propanolamine and butanolamine; heterocyclic, aromatic, cycloaliphatic and aliphatic primary amines; diamines; carboxylic acids such as aliphatic, aromatic and heterocyclic carboxylic acids, for instance oxalic, succinic, glutaric, adipic, sebacic and terephthalic acids; and aminocarboxylic acids. For example, the at least one compounds (4) may be aliphatic diols.
The polyurethanes may, for example, be formed from at least one additional compound (5) having a silicone skeleton, such as polysiloxanes, polyalkylsiloxanes or polyarylsiloxanes, for example, polyethylsiloxanes, polymethylsiloxanes and polyphenylsiloxanes, optionally comprising hydrocarbon chains grafted on the silicon atoms.
