Abstract

The disclosure relates to a cosmetic composition for the hair, packaged in an aerosol device, comprising polyols in high concentration together with anionic fixing polymers. It further relates to a cosmetic method for the hair comprising the application of this composition to the hair, and to its use for imparting a waxy effect to the hair.

Description

This application claims benefit of U.S. Provisional Application No. 60/434,677, filed Dec. 20, 2002.[0001]

The present disclosure relates to a cosmetic composition for the hair, packaged in an aerosol device, comprising polyols in high concentration together with anionic fixing polymers. It further relates to a cosmetic method for the hair comprising the application of this composition to the hair, and to its use for imparting a waxy effect to the hair.

For the purposes of the present disclosure, “cosmetic compositions for the hair” are understood as meaning hair fixing and/or holding compositions, hair care compositions, hair conditioning compositions, such as compositions for imparting softness to the hair, or hair make-up compositions.

“Composition with a waxy effect” is understood as meaning a pasty composition for holding and/or fixing the individual hairs together by means of a certain slicking or greasing effect without the hardening effect of fixing sprays, while at the same time preserving the natural gloss of the hair.

The cosmetic composition for hair according to the disclosure can be used in a rinsed or leave-in application.

Hair styling compositions, such as lacquers and sprays, packaged in the form of an aerosol spray can be generally made up of a liquid phase comprising at least one film-forming polymer in a cosmetically acceptable alcoholic or aqueous-alcoholic medium, and a propellant, which can be a gas liquefied under reduced pressure or dissolved in the liquid phase.

The majority of hair styling products with a waxy effect are presented in the form of a more or less viscous paste which is applied to the hair by hand. In general, these products are packaged in tubes or in containers fitted with a lid.

It would be desirable to present this type of hair styling product in packaging that is easier to use.

In the hair product art, attempts are being made to manufacture aerosol lacquers containing reduced amounts of volatile organic compounds, such as ethanol, essentially for ecological reasons, while at the same time preserving good hair shaping and holding properties. A problem that may be posed by the search for such a product is to find cosmetic compositions that impart a waxy effect to the hair without exhibiting the disadvantages expressed above.

Surprisingly and unexpectedly, it has been discovered by the present inventors that it is possible to impart a waxy effect to the hair without detracting from its cosmetic properties, such as its natural softness, by using polyols in high concentration combined with anionic fixing polymers, packaged in aerosol form.

The present disclosure thus relates to a cosmetic composition for the hair, packaged in an aerosol device, comprising:

a) at least one anionic fixing polymer, present in an amount ranging from 0.5% to 10% by weight, based on the total weight of the aerosol composition,

b) at least one polyol with a molecular weight less than 500, present in an amount greater than 15% by weight, based on the total weight of the aerosol composition,

c) an aqueous-alcoholic or aqueous medium comprising at least 10% by weight of water, based on the total weight of the aerosol composition, and

d) at least one propellant gas present in an amount greater than or equal to 30% by weight, based on the total weight of the aerosol composition.

The present disclosure also relates to a hair styling method using the composition disclosed herein, packaged in an aerosol device.

Additional characteristics, features and advantages of the disclosure are discussed in the description and the various Examples which follow.

This disclosed combination of anionic fixing polymers and polyols affords aerosols with a low VOC content, for example, a VOC content less than or equal to 55%.

Without being bound by theory, it is believed by the present inventors that the waxy effect of the compositions disclosed herein is obtained by combining at least one polyol with a molecular weight below 500, in high concentration, with one or more anionic fixing polymers. The polyols provide the “slicking” or “greasy” aspect of waxes and the associated anionic fixing polymers provide the “stiffening of the grease”, which enables the hair to be shaped and held in the desired configuration; waxes are completely absent from the formulation.

Anionic Fixing Polymer

The anionic fixing polymers useful in the compositions disclosed herein are polymers comprising groups chosen from derivatives of carboxylic, sulphonic and phosphoric acid groups, and have a number-average molecular weight ranging from 500 to 5,000,000.
