Abstract:
A high efficacy stick antiperspirant/deodorant free of added stearyl alcohol comprising in weight percent based on the total weight of the composition:(a) 30-70% volatile cyclomethicone; (b) 10-25% of an antiperspirant active; (c) 1-15% of an emollient; (d) 1-14% of polyethylene comprising one or more members selected from the group consisting of homopolymers and copolymers of polyethylene wherein the polyethylene (i) is at least 90% linear; (ii) has a molecular weight in the range of 300-3000; (iii) has a melting point in the range of 50-129 degrees C.; and (iv) has a polymer backbone of CH3CH2â€”(CH2â€”CH2)nâ€”CH2â€”CH3, where n is an average number and is selected to be in the range of 10-106; (e) 0.3-7% of a wax as a co-gellant with the polyethylene wherein the wax has a melting point in the range of 40-97 degrees C.; and (f) 1-30% of an elastomer in cyclomethicone composition comprising a cyclomethicone (and) dimethicone crosspolymer made with an &boxH;Siâ€”H containing polysiloxane and an alpha, omega-diene of formula CH2&boxH;CH(CH2)xCH&boxH;CH2, where x=1-20, to form a gel by crosslinking and addition of &boxH;Siâ€”H across double bonds in the alpha, omega diene, which crosspolymer has a viscosity in the range of 50,000-3,000,000 centipoise; provided that the ratio of wax:polyethylene is in the range of 1:1-1:10.
