## Background
This application claims benefit of U.S. Provisional Application No. 61/298,283, filed Jan. 26, 2010. This application also claims benefit of priority under 35 U.S.C. §119 to French Patent Application No. 0959486, filed Dec. 23, 2009.


Disclosed herein is a cosmetic composition for cleansing and conditioning keratin fibres, for example human keratin fibers such as the hair, comprising, in a cosmetically acceptable medium, at least one organosilicon compound, at least one anionic surfactant chosen from sulfate and sulfonate anionic surfactants, at least one carboxylic anionic surfactant and at least one amphoteric surfactant. Also disclosed herein is a cosmetic process for treating keratin fibres employing the cosmetic composition.
It may be common practice to use detergent compositions (such as shampoos) based, for example, on standard surfactants such as anionic, nonionic and/or amphoteric type, further such as anionic type, for cleansing and/or washing keratin materials such as the hair. These compositions can be applied to wet hair and the lather generated by massaging or frictioning with the hands makes it possible, after rinsing with water, to remove the diverse types of soiling initially present on the hair or the skin.
These detergent compositions can have good washing power, but their intrinsic cosmetic properties however may remain quite poor, for example, due to the fact that the relatively aggressive nature of such a cleansing treatment may in the long term give rise to more or less pronounced damage on hair fibers, associated, for example, with the gradual removal of the fats or proteins contained in or at their surface.
Thus, to improve the cosmetic properties of the above detergent compositions, and, for example, of those that can be applied to sensitized hair (i.e. hair that may be damaged or embrittled by the action of external atmospheric agents such as light and/or bad weather, and/or mechanical or chemical treatments such as blow-drying, combing, dyeing, bleaching, permanent-waving and/or relaxing), it may now become common practice to introduce into these compositions at least one additional cosmetic agent known as conditioning agent, which may be intended mainly to repair or limit the harmful or undesirable effects caused by the various treatments and/or attacking factors to which the hair fibers may be more or less repeatedly subjected. The at least one conditioning agent may, of course, also improve the cosmetic behaviour of natural hair.
With this aim, it may have already been proposed to use cosmetically active organic compounds such as cationic polymers and silicones as conditioning agents in detergent cosmetic compositions such as shampoos, to give the hair at least one satisfactory cosmetic property, for example, chosen from improved sheen, softness, suppleness, lightness, a natural feel and improved disentangling.
However, those compounds in cosmetic washing and hair-conditioning compositions may not give the hair satisfactory and/or long-lasting styling properties. For example, these compositions may generally afford styling effects, such as hair hold, body and/or manageability effects, which may remain insufficient and which may have a tendency to fade out after washing the hair with a standard shampoo.
Now, it can be found that consumers may be increasingly in search of washing compositions that can be not only capable of appropriately conditioning the hair, but also capable of affording satisfactory and long-lasting styling effects.
Thus, compositions for washing and conditioning the hair that comprise at least one organosilicon compound, such as 3-aminopropyltriethoxysilane, may have been developed in order to be able to satisfy these requirements. These washing compositions may make it possible to condition the hair, such as by giving it a satisfactory soft feel, while at the same time imparting pronounced and long-lasting styling effects.
Furthermore, these compositions can be beneficial since they may facilitate the shaping of fine hair and may give beneficial styling effects to wavy or curly hair, for example, by improving the fashioning and control of the curls.
However, washing compositions comprising such organosilicon compounds may have the drawback of changing substantially over time under normal storage conditions as a function of the temperature, for example, in terms of their viscosity and/or their visual aspect. In other words, these compositions may not be stable, which can be reflected by a cloudy visual aspect and/or by an unsatisfactory texture on storage.
For example, it has been found that organosilicon compounds, such as 3-aminopropyltriethoxysilane, can be chemically incompatible with essentially all the surfactants, such as anionic surfactants, which may be present in washing compositions, leading to the stability problems encountered.
Moreover, it may have been observed that the introduction of certain organosilicon compounds, for example, amino derivatives such as 3-aminopropyl-triethoxysilane, into washing compositions that, for example, have a pH ranging from 4 to 7, may also give rise to stability problems due to the alkaline nature of these compounds.
It can be beneficial to develop cosmetic compositions for cleansing and conditioning keratin fibers, comprising at least one organosilicon compound, wherein these compositions do not have at least one of the drawbacks described above, e.g. being stable over time and/or allowing hair to be conditioned satisfactorily while at the same time affording long-lasting, and/or powerful styling effects, for example, in terms of volume, body and/or texturizing of the hair.
Provided herein are detergent and conditioning compositions for keratin fibres, which can have at least one of the beneficial properties discussed above, comprising at least one organosilicon compound as defined hereinbelow, at least one anionic surfactant chosen from sulfate and sulfonate anionic surfactants, at least one carboxylic anionic surfactant different from the preceding ones, chosen from alkyl ether carboxylic acids and salts thereof, and at least one amphoteric surfactant.
For example, the use of at least one amphoteric surfactant and of at least one carboxylic anionic surfactant chosen from alkyl ether carboxylic acids and salts thereof, in cosmetic compositions comprising at least one organosilicon compounds and at least one anionic surfactants chosen from sulfate and sulfonate anionic surfactants, can make it possible to render them stable on storage both at room temperature (20-25° C.) and at 45° C., for example, in terms of their visual aspect and/or their viscosity.
As disclosed herein, the term “stable” means that the visual aspect and/or viscosity of these compositions do not change substantially over time under storage test conditions, for example at room temperature (20° C.-25° C.) and/or at 45° C. and/or at 4° C. for two months following their manufacture.
Furthermore, the compositions disclosed herein may lead to satisfactory treatment of the hair, thus giving it a satisfactory soft feel, improved disentangling, softness and/or suppleness.
Moreover, the compositions disclosed herein may afford powerful styling effects, for example, in terms of their provision of volume, body and/or manageability, and/or do so in a lasting manner.
Furthermore, the compositions disclosed herein may facilitate the shaping of the hair, for example, of fine hair, and/or may give improved styling effects to curly hair, for example, in terms of the fashioning and/or control of the curls, and/or do so in a lasting manner.
Provided herein is a cosmetic composition for washing and conditioning keratin fibres, for example, human keratin fibers such as the hair, comprising, in a cosmetically acceptable medium:
(i) at least one organosilicon compound chosen from silanes comprising one silicon atom and siloxanes comprising two or three silicon atoms, wherein the at least one organosilicon compound comprises at least one basic chemical functional group and at least one group chosen from hydroxyl and hydrolysable groups per molecule;
