Abstract:
A two-phase roll-on antiperspirant and/or deodorant comprising(a) a clear, translucent or opaque non-polar phase having a viscosity in the range of 20 cps-9,000 cps made by combining: (1) a cross-linked or partially cross-linked non-emulsifying siloxane elastomer in an amount sufficient to provide a non-polar phase having a viscosity in the range of 20-9,000 cps; (2) 0.1-70 weight % of one or more lipophilic emollients selected from the group consisting of: (i) 0.1-40 weight % of a linear or cyclic volatile silicone; (ii) 0.1-20 weight % of a volatile, nonpolar hydrocarbon having from 4-30 carbons; (iii) 0.1-20 weight % of a benzoic acid ester selected from the group consisting of C12-C20 benzoate esters; (iv) 0.01-8 weight % of a propoxylated fatty alcohol having 4-16 carbons and 2-14 moles of propoxylation; and (3) optionally one or more ingredients selected from the group consisting of fragrance; vitamins; and pigments, and coloring agents; and (b) a clear, translucent or opaque polar phase having a viscosity in the range of 20-9,000 cps made by combining: (1) one or more members selected from the group consisting of water, glycols and polyhydric alcohols; and (2) an antiperspirant active salt which is soluble or suspendible in the polar phase; wherein the polar phase (i) comprises a sufficient amount of water, glycols or polyhydric alcohols to dissolve or suspend the antiperspirant active, and (ii) optionally may comprise up to 30 weight % water; up to 16.00 weight % ethyl alcohol; up to 16 weight % isopropyl alcohol; or mixtures or any of the foregoing; (3) 0.1-2.5 weight % of a water soluble cationic derivative selected from the group consisting of hydroxyethyl cellulose and its copolymers; and (c) optionally one or more ingredients selected from the group consisting of (i) &lE;1.0 weight % of mica with an average particle size in the range of 10-125 microns; (ii) an effective amount of a suspending agent; (iii) an antimicrobial agent; (iv) fragrance; (v) 0.05-5.0 weight % of a masking agent; (vi) 0.1-1.0 weight % of a polymer of ethylene oxide; and (vii) a cosmetically acceptable coloring agent.
