High efficacy antiperspirant stick with concentrated elastomer

摘要

A high efficacy antiperspirant/deodorant stick product may be made by combining (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 (especially 300-1000 and more especially 300-500); (iii) has a melting point in the range of 50-129 degrees C.; and (iv) has a polymer backbone of CH3CH2-(CH2-CH2)n-H, 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 =Si-H containing polysiloxane and an alpha, omega-diene of formula CH2=CH(CH2)xCH=CH2, where x=1-20; provided that the ratio of wax:polyethylene is in the range of 1:1-1:10.
