Definitions

• novel cosmetic compositions with improved properties which are intended for both cleaning and conditioning keratin materials, such as the hair, and comprising, in a cosmetically acceptable support, at least one anionic surfactant, at least one other surfactant chosen from amphoteric, nonionic and cationic surfactants, and at least one polysaccharide chosen from starch hydrolyzates and nonionic and anionic fructans.
• compositions in the above-mentioned cosmetic application.
• detergent hair compositions or shampoos based essentially on standard anionic, nonionic and/or amphoteric surfactants, for example, anionic surfactants, to clean and/or wash the hair.
• These compositions may be applied to wet hair and the lather can be generated by massaging or rubbing with the hands. The massaging or rubbing can remove, after rinsing with water, the various types of soiling which may initially be present on the hair.
• these base compositions can have good washing power, but the intrinsic cosmetic properties associated with them can nevertheless remain fairly poor, owing, for example, to the fact that the relatively aggressive nature of such a cleaning treatment can, in the long run, lead to more or less pronounced damage to the hair fiber. This damage can be associated, for example, with the gradual removal of the lipids or proteins contained in or on the surface of this fiber.
• conditioners may, for example, repair or limit the harmful-or undesirable effects induced by the various treatments or aggressions to which the hair fibers may be subjected more or less repeatedly.
• conditioners may, of course, also improve the cosmetic behavior of natural hair.
• the conditioners most commonly used to date in shampoos are, for example, cationic polymers, silicones and/or silicone derivatives, which may give washed, dry or wet hair an ease of disentangling and a softness which may be markedly better than that which can be obtained with corresponding cleaning compositions from which they are absent.
• cationic polymers for this purpose can have at least one drawback.
• some of these polymers can become deposited on the hair in a substantial amount during repeated use, and may lead to at least one of the following undesirable effects: unpleasant, laden feel, stiffening of the hair and adhesion between the fibers, which may affect the styling.
• These drawbacks may be accentuated in the case of fine hair, which can lack liveliness and volume.
• compositions directed toward satisfying such a need are disclosed herein.
• a washing base for example, a washing base comprising at least one anionic surfactant and at least one other surfactant chosen from amphoteric, nonionic and cationic surfactants in a particular ratio, and further comprising at least one particular polysaccharide
