  The present invention relates to the use of polysaccharide compounds with non-polymeric siloxane graft (s) in cosmetics, and the compositions of the present invention. including them, as well as new polysaccharide compounds with non-polymeric siloxane graft (s) In the field of cosmetics, it is sought in particular to improve the cosmetic properties of keratin materials, such as the hair and the skin, and more particularly sensitized hair, ie hair which is damaged or weakened, especially under the chemical action of atmospheric agents and / or hair treatments such as permanent dyes or discolorations.

  For this purpose, it is usual to use complementary cosmetic agents known as conditioning agents, for example cationic polymers or silicones, intended mainly to repair or limit the harmful or undesirable effects induced by the various treatments or aggressions that are undergone, more or less repeated, the hair fibers. These conditioning agents also improve the cosmetic behavior of natural hair.

  Other conditioning agents, such as the amphoteric polysaccharides described in US 6,066,727, can be used in hair cosmetic compositions.

  However, these conditioning agents are not always very effective as regards the conditioning and persistence of the cosmetic properties. After several uses, the hair is loaded and lacks lightness and flexibility.

  The Applicant has found, surprisingly and unexpectedly, that the use of polysaccharide compounds with non-polymeric siloxane graft (s) in cosmetics makes it possible to overcome the disadvantages described above and to obtain excellent results. cosmetic properties such as an excellent conditioning and protective effect of the hair, a good disentangling of the hair, a softness and a smoothing effect of the keratinous fiber.

  Such compounds and their method of preparation are described in the article Cellulose fiber / poly (ethylene-co-methacrylic acid) composites with ionic interphase of Xiaolin Cai et al, Composites Part A 34 ,. 2003, pages 1075-1084.

  In addition, the use of these polysaccharide compounds with non-polymeric siloxane graft (s) leads to a good remanence of these properties, even after several washes of the hair without observing too much deposit which would lead to hair. loaded, non-malleable and non-flexible.

  These conditioning agents also give the skin cosmetic properties such as good hydration.

  The subject of the present invention is therefore the use of polysaccharide compounds with non-polymeric siloxane graft (s) as described below, in cosmetics, in particular for the cosmetic treatment of keratin materials, such as the care and protecting the hair, styling, perm, straightening, coloring or fading, or cleansing and caring for the skin.

  Another subject of the invention is a cosmetic composition comprising at least one polysaccharide compound with non-polymeric siloxane graft (s) as described below, in a cosmetically acceptable medium.

  It also relates to new compounds as defined below.

  Other objects, features, aspects and advantages of the invention will emerge even more clearly on reading the description and the various examples which follow.

  The polysaccharide compounds with non-polymeric siloxane graft (s) used according to the invention can be obtained by reacting a polysaccharide and a siloxane compound corresponding to formula (I):
