LOW-IRRITATION ANTIPERSPIRANT AND DEODORANT COMPOSITIONS

摘要

Disclosed are topical compositions which comprise from about 0.01 % to about 60 % by weight of an antiperspirant and/or deodorant active; from about 1 % to about 60 % by weight of a volatile, nonpolar hydrocarbon liquid having a solubility parameter of less than about 7.5 (cal/cm3)0.5 and a vapor pressur e as measured at 25 ~C of from about 0.01 mmHg to about 6.0 mmHg; and from abo ut 1 % to about 60 % by weight of a skin irritation-mitigating material having a vapor pressure equal to or less than that of the volatile, nonpolar hydrocarbon liquid, preferably a silicone-containing liquid; wherein the weight ratio of the volatile, nonpolar hydrocarbon liquid to the mitigating material is from about 5:1 to about 1:50. It has been found that the volatil e, nonpolar hydrocarbon liquid as defined herein can cause skin irritation when used in an antiperspirant or deodorant composition, when used at relatively low concentrations, but that the skin irritation can be reduced or eliminate d by the addition of a skin irritation-mitigating material, provided the material has the requisite vapor pressure and weight ratio relative to the volatile, nonpolar hydrocarbon liquid.
