The present invention relates to novel cosmetic compositions comprising a cosmetically acceptable medium at least one ethylenic copolymer dimethicone / dimethicone unsaturation with a viscosity between 106 and 100,106 cP in an aqueous emulsion and at least one non-cellulosic thickener. It is well known that hair that has been sensitized (ie damaged and / or fragile) to varying degrees under the action of atmospheric agents or under the action of mechanical or chemical treatments, such as colorations, discolorations and / or permanent, are often difficult to untangle and comb, 'and they lack softness. In the compositions for the washing or treatment of keratin materials such as hair, the use of conditioning agents, particularly silicones, has already been recommended to facilitate the disentangling of the hair.

REF: 124200 hair and to communicate softness and flexibility. However, the cosmetic advantages mentioned above are accompanied unfortunately also in dried hair, by certain cosmetic effects considered undesirable, namely caking hairstyle (lack of lightness of the hair), lack of smoothness (inhomogeneous hair from root to the tip), an unpleasant touch, loaded, a stiffness of the hair and an interfiber adhesion that affects the hairstyle, in particular in repeated uses. These drawbacks are accentuated in the case of fine hair, which lacks liveliness and volume. In summary, it happens that current cosmetic compositions containing silicones do not completely satisfy. The applicant has now discovered that the association of at least one particular silicone copolymer with a viscosity comprised between 106 and 100.106 cP in aqueous emulsion with non-cellulose thickeners, makes it possible to remedy these drawbacks. Thus, after considerable research conducted in this matter, it has now been discovered by the Applicant that by using the combination of at least one specific silicone copolymer viscosity between 106 and 100'6 cP aqueous emulsion thickeners noncellulosic a compositions in particular for the hair, it is possible to limit, even suppress, the problems generally related to the use of such compositions, namely in particular the caking (touch loaded in repeated applications), the lack of smoothing and softness of the hair, maintaining the other advantageous cosmetic properties that are inherent in compositions based on conditioning agents. This association provides cosmetic properties (smoothing, lightness, softness) without the phenomenon of fat contribution to the keratin fibers. On the other hand, the compositions of the invention applied to the skin, particularly in the form of a foaming bath or shower gel, provide an improvement in the softness of the skin. Thus, according to the present invention will now propose novel cosmetic compositions comprising, in a cosmetically acceptable medium, at least one aqueous emulsion of at least one silicone copolymer as defined below, wherein the copolymer indicated, a viscosity between 106 and 100,106 cP and at least one non-cellulosic thickener.
