Abstract:
A high efficacy stick antiperspirant/deodorant free of added stearyl alcohol and which comprises 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) 1-40% of an elastomer in cyclomethicone composition comprising a dimethicone/vinyldimethicone crosspolymer composition made by reacting (in the presence of a platinum catalyst) a polymethylhydrogensiloxane with an alpha, omega-divinylpolydimethyl siloxane for which the dimethicone/vinyldimethicone crosspolymer composition (1) is used at a concentration of 4-10% in cyclomethicone,(2) has a refractive index in the range of 1.392-1.402 at 25 degrees C., and (3) has a viscosity in the range of 0.013-1Ã—104 Pascal seconds; provided that the ratio of wax:polyethylene is in the range of 1:1-1:10.
