Description

COMPOSITION PAR ?, STYLE HAIR ECHNICAL FIELD The present invention relates to a composition for styling hair that provides a flexible film texture and good combing retention. In particular, the invention relates to a composition for styling hair in the form of a foam.

BACKGROUND OF THE INVENTION The desire to make the hair retain a particular shape is widely maintained. The most common methodology to achieve this is the application of a composition to moistened hair, or after washing with shampoo and / or conditioning, or to stylized and dry hair. These styling compositions provide temporary fixation benefits and can be removed with water or by shampooing. The materials used in the compositions to provide the fixing benefits have generally been resins and have been applied in the form of foams, gels, lotions or sprays. Additionally, these styling compositions are formulated for additional purposes, such as shampooing, conditioning, treatment, dyeing and combinations of P96-the same. A main desire of the consumer with respect to the performance of styling compositions has been the ability to retain the hair. Frequent good retention has been associated with strong and prolonged hair styling and / or fixation. However, it has also been observed that styling compositions having a retention capacity exceeding a certain magnitude can also give the hair a harsh feeling, making combing difficult, as well as being difficult to remove by shampooing. In addition, in recent years, some customers have expressed a desire to have hair styling products that allow the rearrangement of hair without compromising the capacity of hair retention. Since styling compositions with good retention capacity commonly provide a rigid film texture, it was difficult to provide a flexible film texture composition that would allow rearrangement of the hair. In this way, there is a desire to have hair styling compositions that have good retention without compromising the ability to rearrange the hair, can provide a soft and supple feeling to the hair, and can be easily removed.

P964 of the hair in the wash with shampoo. It is also desirable to have a composition for styling the hair in the form of a foam that provides foams having improved stability at rest but which undergoes rapid crushing to form creamy liquids under shear stress.

SUMMARY OF THE NONVENTION Thus, the present invention provides a composition for styling hair, comprising, by weight: (a) up to about 10% of at least one organic adhesive polymer; (b) up to about 5% of at least one surfactant comprising an ethoxylated alcohol having a chain length of up to about 16 carbon atoms and an ethoxylation degree of from about 3 to about 20 ethoxy groups per mole; and (c) a solvent. The composition for hair styling according to the invention can be in any form suitable for application to hair, such as for example foams, gels, lotions or sprays. However, it is preferred that the composition be in the form of a foam also comprising a propellant.

DETAILED DESCRIPTION The organic polymer (a) is present in the composition in an amount of up to about 10% by weight, preferably from about 1 to 3% by weight and more preferably from about 2 to 2.5% by weight. The polymer can be any polymer for conventional organic styling, which include: cationic, anionic, amphoteric and neutral polymers. Cationic polymers are preferred, anionic and amphoteric. The ethoxylated alcohol (b) is present in an amount of up to about 5% by weight, more preferably, from about 0.1% to about 1.0% by weight. The ethoxylated alcohol can be used as the sole surfactant or in conjunction with a co-surfactant. In accordance with the present invention, it has been found that improved foams are provided by incorporating a small amount of an ethoxylated alcohol into a styling composition, including a styling polymer. The styling polymer is also incorporated in a small amount with respect to conventional compositions for styling hair.

It is known that surfactants stabilize liquid walls or lamellae within foam structures. In accordance with the invention, it has been found that the use of ethoxylated alcohols have a specific chain length and a specific degree of ethoxylation leads to improved stability of the lamellae. In addition, under shear conditions, the foam quickly collapses to leave a creamy lime that can be quickly applied to the hair for styling. The chain length of the major alcohol and the degree of ethoxylation can be adjusted within the specified ranges to influence the ability of the surfactant to stabilize the lamellae under different shear conditions.

In general, it will be applied to the hair, from approximately 0.5g to approximately 30g of the product, depending on the particular product formulation, the type of dispenser, the length of the hair and the type of hair style. The present invention is further illustrated with reference to the following Examples. Hair styling compositions are formulated as foams by conventional techniques known in the art. All the examples provided foams that were stable at rest for a long period of time but that, when subjected to shear stress, underwent rapid crushing to form creamy liquids that could be easily and effectively worked on the hair.

P964 n DOBANOL 91-8: - C9-11 Pareth 8 provided by Shell m DMDM hydantoin: - dimethylol dimethyl hydantoin í3i Fragrance Takasago 6397: - perfume supplied by Takasago The Examples showed that the relative proportions of the polymer and the ethoxylated alcohol can be adjusted to provide optimum foam properties. Specifically, the foams resulting from the compositions of the Examples, showed that increasing the polymer level from 2.0% (Example 1) to 2.25% (Example 2) and 2.5% (Example 3) and maintaining at the same time the same level of Ethoxylated alcohol, provides a higher viscosity construction and poorer performance speed. In addition, increasing the level of ethoxylated alcohol from 0.25% (Example 4) to 0.5% (Example 5) 0.75% (Example 6) and 1.0% (Example 7) while maintaining the same polymer level results in a characteristic of rubber and increased stiffness in the foam and the foam becomes harder to break under shear stress.
