Description

COSMETIC COMPOSITION CONTAINING A NON-AMINO SILICONE, A LIQUID FATTY ESTER AND AN AMINO SILICONE, PROCESS AND USE The present invention relates to novel cosmetic compositions comprising one or more non-amino silicones, one or more particular liquid fatty esters and one or more particular amino silicones.

It is well known that hair which has been sensitized (i.e. damaged and/or embrittled) to varying degrees under the action of atmospheric agents or under the action of mechanical or chemical treatments, such as dyeing, bleaching and/or permanent-waving, is often difficult to disentangle and to style, and lacks softness.

It has already been recommended to use conditioners, in particular cationic or amphoteric polymers, fatty acid esters or volatile or non-volatile non-amino silicones in compositions for washing or caring for keratin materials such as the hair, in order to facilitate disentangling of the hair and to give it softness and manageability. However, the cosmetic advantages mentioned above are also unfortunately accompanied, on dried hair, by certain cosmetic effects considered to be undesirable, namely lankness of the hairstyle (lack of lightness of the hair) and lack of smoothness (hair not uniform from the root to the end). Amino silicones are generally used in cosmetic compositions as conditioners for improving the softness and the disentangling of the hair. However, it has been noted that, owing to their strong affinity to the hair, some of these amino silicones become deposited thereon to a large extent during repeated use, and lead to adverse effects such as an unpleasant laden feel, stiffening of the hair and interfibre adhesion which has an effect on styling. These drawbacks are accentuated in the case of fine hair, which lacks liveliness and body. Combinations of particular amino silicones, oils comprising ester functions and non-amino silicones are also known in document WO2009/059455. However, these combinations are not entirely satisfactory in particular in terms of sheen, smoothness and softness of the hair. It was therefore necessary to develop a cosmetic composition, in particular a detergent composition, especially a shampoo, which has a satisfactory aesthetic appearance, which is stable and which makes it possible to obtain good cosmetic performance on the keratin materials, namely in particular the hair and the scalp, and more particularly sensitized hair.

The applicant has now discovered that the combination of a non-volatile, non- amino insoluble silicone, of a particular amino silicone and of a particular liquid fatty ester makes it possible to remedy these drawbacks. Indeed, it has been noted that the use of the compositions of the present invention makes it possible to obtain, on keratin materials, in particular the hair, very good cosmetic properties particularly in terms of lightness, disentangling, smooth feel, body and sheen. It has also been noted that the compositions of the invention make it possible to obtain dried hair that looks generally smoother.

When the compositions comprise foaming surfactants, their foaming properties, in particular the initiation of foam, are not degraded.

In addition, the compositions rinse out easily.

The compositions of the invention applied to the skin, in particular in the form of a bubble bath or of a shower gel, give an improvement in the softness of the skin. Thus, according to the present invention, novel cosmetic compositions are now proposed, comprising:

(i) - one or more non-volatile, non-amino polydimethylsiloxanes,

(ii) - one or more acyclic liquid fatty esters of a monoalcohol, and

(iii) - one or more particular amino silicones.

A subject of the invention is also the use of a composition as defined above, for giving the hair sheen, lightness, softness, a smooth feel and/or suppleness.

Another subject of the invention relates to a process for treating keratin materials, such as the hair, characterized in that it consists in applying, to said materials, a cosmetic composition according to the invention.

According to the present invention, the term "keratin materials" is understood to mean the hair, the eyelashes, the eyebrows, the skin, the nails, the mucous membranes or the scalp, and more particularly the hair.

The various subjects of the invention will now be detailed. All the meanings and definitions of the compounds used in the present invention given below are valid for all of the subjects of the invention.

According to the present invention, the term "sensitized hair" is understood to mean hair which has undergone physical external attacks (light, heat, waves, etc.), mechanical attacks (blowdrying, repeated combing or brushing, etc.) or chemical attacks (oxidation dyeing, bleaching, permanent waving, straightening, etc.). The compositions according to the invention are particularly effective on hair sensitized by chemical attacks. The term "at least one" will be understood to mean "one or more", i.e. one, two, three or more.

For the purpose of the present invention, the term "insoluble compound" is intended to mean a compound which, at 25°C and at a concentration greater than or equal to 0.1 % by weight in water, does not form a transparent isotropic solution. For the purpose of the present invention, the term "non-volatile compound" is intended to mean a compound which, at ambient temperature (on average 25°C), is capable of remaining on the hair for several hours. A non-volatile compound has in particular a vapour pressure, at ambient temperature (on average 25°C), of less than 2.66 Pa (0.02 mm of mercury), better still less than 0.13 Pa (0.001 mm of mercury).

The minimum amount of surfactant is then that which is just sufficient to confer a satisfactory foaming and/or detergent power on the final composition.

Thus, according to the invention, the detergent surfactant can represent from 3% to 30% by weight, preferably from 6% to 25% by weight, and even more preferentially from 8% to 20% by weight, of the total weight of the final composition.

The foaming power of the compositions according to the invention, characterized by a foam height, is generally greater than 75 mm; preferably greater than 100 mm measured according to the modified Ross-Miles method (NF T 73-404/ISO696). The modifications of the method are the following:

The measurement is carried out at the temperature of 22°C with osmosed water. The concentration of the solution is 2 g/l. The height of the drop is 1 m. The amount of composition which drops is 200 ml. These 200 ml of composition fall into a graduating cylinder having a diameter of 50 mm and containing 50 ml of the test composition. The measurement is carried out 5 minutes after the flow of the composition is stopped.

In a second preferred variant, when the composition is in the form of a care composition such as an optionally rinse-out conditioner, it advantageously comprises one or more cationic surfactants, the concentration of said surfactants generally ranging from 0.1 to 10% by weight and preferably from 0.5 to 5% by weight, relative to the total weight of the composition. The compositions of the invention can also be in the form of permanent-waving, straightening, dyeing or bleaching compositions, or else in the form of compositions which are rinse-out, to be applied before or after dyeing, bleaching, permanent-waving or straightening or else between the two steps of a permanent- waving or straightening operation.

The compositions according to the invention can be in the form of aqueous or aqueous-alcoholic skincare and/or haircare lotions.

The cosmetic compositions according to the invention can be in the form of a gel, a milk, a cream, an emulsion, a thickened lotion or a mousse, and be used for the skin, the nails, the eyelashes, the lips and more particularly the hair.

The compositions can be packaged in various forms, in particular in vaporizers, pump-dispenser bottles or in aerosol or nonaerosol containers so as to apply the composition in vaporized form or in the form of a mousse. Such packaging forms are indicated, for example, when it is desired to obtain a spray, a lacquer or a mousse for treating the hair.

A subject of the invention is also a process for treating keratin materials such as the skin or the hair, characterized in that it consists in applying, to the keratin materials, a cosmetic composition as defined above, and then in optionally rinsing with water after an optional leave-in time.

In all that follows and in all the aforementioned, the percentages expressed are by weight.
