Claims41
A clear personal care composition in the form of a microemulsion, the composition comprising water, a volatile silicone, a silicone polyether having a molecular weight greater than 1,000 and an HLB greater than 4, and one or more alcohols selected from the group consisting of monohydric alcohols and polyhydric alcohols;
- wherein the composition is clear because the composition is in the form of a microemulsion, not because of refractive index matching of a water phase and an oil phase.
A clear personal care composition in the form of a microemulsion, the composition comprising, by weight, 10% to 50% water, 3% to 25% antiperspirant salt (U.S.P.), 10% to 70% volatile silicone, 1% and 90% of one or more alcohols selected from the group consisting of monoalcohols and polyols, and 1% to 20% silicone polyether having a molecular weight between 2,000 and 100,000 daltons and an HLB greater than 4;
- wherein the composition is clear because the composition is in the form of a microemulsion, not because of refractive index matching of a water phase and an oil phase.
A method of making a personal care composition in the form of a microemulsion comprising combining, by weight, 10% to 50% water, 3% to 25% antiperspirant salt (U.S.P.) 10% to 70% volatile silicone, 1% and 90% of one or more alcohols selected from the group consisting of monoalcohols and polyols, and 1% to 20% silicone polyether having a molecular weight between 2,000 and 100,000 daltons and an HLB greater than 4 at room temperature to provide the composition;
- wherein the composition is clear because the composition is in the form of a microemulsion, not because of refractive index matching of a water phase and an oil phase.
