Description

Cosmetic composition comprising a bis-amino silicone, a cationic surfactant, a fatty alcohol and a fatty alcohol ester, cosmetic treatment method and use

The present invention relates to a cosmetic composition comprising at least one alpha, omega-bis-amino silicone, at least one cationic surfactant, at least one fatty alcohol and at least one particular fatty alcohol ester. The invention also relates to a method for the cosmetic treatment of keratin materials, in particular keratin fibers such as the hair, comprising the application of such a composition as well as the use of such a cosmetic composition for the cosmetic treatment of keratin materials , in particular human keratin fibers such as hair.

Hair is generally damaged and weakened by the action of external atmospheric agents such as light and bad weather, as well as by mechanical or chemical treatments such as brushing, combing, dyeing, bleaching, perms and/or straightening, even repeated washing.

The hair is thus damaged by these various factors and can in the long run become dry, rough, brittle or dull, in particular in fragile places, and more particularly at the level of the ends.

Thus, to remedy these drawbacks, it is usual to have recourse to hair care which uses compositions intended to condition the hair by providing it with satisfactory cosmetic properties, in particular smoothing, shine, softness, suppleness, lightness, a natural feel and good detangling properties.

These hair care compositions, intended to be applied regularly to the hair, can be, for example, conditioners, masks or serums, and can be in the form of gels, hair lotions and conditioning creams. care more or less thick.

It is in particular known to use compositions in the form of oily serums, containing combinations of silicone or non-silicone oils.

However, such compositions still all too often lead to excessive lubrication of the keratin fibres, which results in a greasy or even sticky feel to them, and a heavy, heavy visual appearance.

In addition, the compositions containing oils, once applied to the hair, frequently lead to effects which are not very pleasant to the touch, in particular the hair tends to be rough and/or to "squeal" (that is to say produce a unpleasant sound effect) especially when rubbing the hair together while sliding the fingers along the hair from root to tip.

These compositions are generally difficult to rinse out, and do not make it possible to impart a clean feel while having a smooth or soft feel.

Furthermore, the hair treated with such compositions is not easy or quick to dry.

Finally, the immediate benefits provided by such compositions are not always enough for the most damaged hair.
In addition, they are not long lasting and tend to fade quickly, or even disappear, after just one shampoo.

The present invention aims to provide compositions which do not have the drawbacks mentioned above, and which are capable of conditioning keratin materials, in particular keratin fibers such as the hair, in a more durable manner, in particular resistant to at least one shampoo.

This object is achieved by virtue of the present invention, the subject of which is in particular a cosmetic composition comprising:
(i) one or more alpha, omega-bis-amino silicones,
(ii) one or more cationic surfactants,
(iii) one or more fatty alcohols and

(iv) one or more esters of carboxylic acid(s) and alcohol(s) comprising at least 8 carbon atoms.

The compositions according to the invention make it possible to impart good cosmetic properties to keratin materials, in particular to keratin fibres, in particular to the hair; they are particularly suitable for providing a very good level of care, particularly in terms of providing softness, fluidity, shine, suppleness, coating and smoothness to the touch (smooth touch).

In addition, these properties are provided relatively evenly throughout the hair, from root to tip.

It has also been found that the compositions according to the invention have good qualities for use: they are easy to apply and to distribute on the materials or keratin fibers and, if necessary, they are easily and quickly removed by simply rinsing said keratin materials or fibres.

The hair retains a clean feel (not greasy or heavy), despite being conditioned (treated, including soft, supple and flowing).

Even in the absence of rinsing of the composition, when it is used as a leave-on for example, the fibers remain light, unloaded and non-sticky, and have a clean feel.

In addition, these compositions exhibit good durability of the effects over time (at least for 24 hours) and good persistence of the effects, for example to at least one shampoo.

A subject of the invention is also a process for the cosmetic treatment of keratin materials, in particular keratin fibers, in particular human fibers, such as the hair, comprising the application to said keratin materials of a composition as defined above.

Another object of the present invention relates to the use of the composition as defined above for the cosmetic treatment, in particular the conditioning, of keratin materials, in particular human.
