A clear, stable, dry-and-non-sticky feeling antiperspirant having an antiperspirant active, a solvent, and a polar silicone emollient. The antiperspirant active is solubilized in the solvent. The polar silicone emollient has an OH group or polyether or mixture thereof. The polyether has an average length of 6 or less of ethylene oxide, propylene oxide or butylenes oxide groups or mixtures thereof. The polar silicone emollient has a chain of dimethyl siloxane groups ranging in an average total length of 8 to 40 silicone atoms. The polar silicone emollient has a linker which is a hydrocarbon chain of 1 to 8 carbons in average length. The polar silicone emollient represents from about 1 % to about 95 %, more specifically from about 5 % to about 70 %, even more specifically from about 10 % to about 40 % by weight of the antiperspirant. The antiperspirant may be contained in a pressurized or non-pressurized container.

L'invention porte sur un anti-transpirant transparent, stable, sec et non collant comportant un agent actif, dissous dans un solvant et un émollient de silicium polaire. Ledit émollient, qui comporte un groupe OH ou polyéther ou son mélange et une chaîne de groupes de diméthyle siloxane d'une longueur totale moyenne de 8 à 40 atomes de silicium, présente un lieur consistant en une chaîne hydrocarbonée d'une longueur moyenne de 1 à 8 atomes de carbone. Le polyéther présente une longueur moyenne d'au plus 6 groupes d'oxyde d'éthylène, de propylène ou de butylène ou de leurs mélanges. L'émollient représente d'environ 1 % à environ 95 % en poids de l'anti-transpirant, et plus spécifiquement d'environ 5 % à environ 70 % et encore plus spécifiquement d'environ 10 % à environ 40 %. L'anti-transpirant peut être conditionné dans un récipient sous pression ou non.
