<p>A two-phase, elastomer-free, low viscosity, high water roll-on antiperspirant and/or deodorant composition comprising: (A) a non-polar phase having a viscosity up to 200 centipoise and comprising: (a) 0.1-40 weight % of a volatile and/or a nonvolatile silicone selected from the group consisting of linear and cyclic organo-substituted polysiloxanes wherein the viscosity is less than 5 centistokes for volatile silicones and in the range of 5-20 contistokes for non-volatile silicones; (b) 0-25 weight % of a straight or branched chain hydrocarbon polymer which has an average molecular weight in the range of 450-6000 daltons; (c) 0-15 weight % of one or more of a selected low viscosity, lipophilic emollient; and (B) a polar phase having a viscosity in the range of 10-2,000 centipoise and comprising: (a) at least 5 weight % of an antiperspirant active; (b) an aqueous component comprising at least 40% water and a sufficient amount of a C2-3 alcohol, a glycol or a polyhydric alcohol so that the antiperspirant active is dissolved in the aqueous component; and (c) a selected thickening agent; wherein the ratio of oil phase to water phase is in the reange of 15:85-40:60; and whereby the composition is able to form a temporarily stabilized emulsion after shaking for a period not exceeding 24 hours.</p> |
