Total Claims: 6
Claim 1
Independent Claim
147 words
A roll-on perfume composition comprising based on 100 parts by weight of total composition: (a) from 5 parts to 15 parts of an essential perfume oil, (b) from 25 parts to 40 parts of an alcohol selected from the group consisting of ethanol, propanol, isopropanol, t-butanol, sec-butanol, and n-butanol, (c) from 20 parts to 40 parts of a polyoxyethylene polyoxypropylene block copolymer having a molecular weight of from 6550 to 40,000 represented by the formula: HO(C.sub.2 H.sub.4 O).sub.b (C.sub.3 H.sub.6 O).sub.a (C.sub.2 H.sub.4 O).sub.b H wherein a is an integer such that the hydrophobe represented by (C 3 H 6 O) has a molecular weight of from 3250 to 4000 and b is an integer such that the hydrophile represented by (C 2 H 4 O) constitutes from about 50 to 90 weight percent of the copolymer, and (d) from 5 parts to 50 parts of water.
