Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
124 words
A cosmetic unit dosage form comprising a soft gelatin capsule containing a substantially water-free, liquid blend consisting essentially of: (a) from about 0.5% to about 10% of a fragrance; (b) from about 30% to about 60% a foamable mixture of basic surfactants comprising a (diethanol)amine salt of a fatty alcohol (ethylenoxy)sulfate and a fatty acid (diethanol)-amide; and (c) from about 30% to about 60% an amount of a foamable acidic surfactant comprising fatty alcohol(polyethylenoxy)acetic acid effective to render the liquid blend substantially non-reactive with said gelatin capsule while maintaining the foam-producing ability of the surfactants in aqueous media, said percentages being percentages by weight based on the total weight of the composition, said composition containing not more than 10% by weight of other components.
Claim 2
Dependent Claim
124 words
A cosmetic unit dosage form comprising a soft gelatin capsule containing a substantially water-free, liquid blend consisting essentially of: (a) from about 0.5% to about 10% of a fragrance; (b) from about 30% to about 60% a foamable mixture of basic surfactants comprising a (diethanol)amine salt of a fatty alcohol (ethylenoxy)sulfate and a fatty acid (diethanol)-amide; and (c) from about 30% to about 60% an amount of a foamable acidic surfactant comprising fatty alcohol(polyethylenoxy)acetic acid effective to render the liquid blend substantially non-reactive with said gelatin capsule while maintaining the foam-producing ability of the surfactants in aqueous media, said percentages being percentages by weight based on the total weight of the composition, said composition containing not more than 10% by weight of other components.

Claim 7
Dependent Claim
115 words
A cosmetic unit dosage form comprising a soft gelatin capsule containing a substantially water-free liquid blend consisting essentially of: (a) about 0.5-10% fragrance; (b) about 30-60% of a foamable mixture of basic surfactants comprising a fatty acid (diethanol)-amide and a basic surfactant of the formula: (C.sub.8 -C.sub.22)alkyl(OCH.sub.2 CH.sub.2).sub.n OSO.sub.3 H.HN(CH.sub.2 CH.sub.2 OH).sub.2, wherein n is about 1-5; (c) about 30-60% of a foamable acidic surfactant comprising a surfactant of the general formula: (C.sub.8 -C.sub.22)alkyl(OCH.sub.2 CH.sub.2).sub.m OCH.sub.2 CO.sub.2 H, wherein m is about 3-15; and (d) about 2-5% propylene glycol said percentages being percentages by weight based on the total weight of the composition, said composition containing not more than 10% by weight of other components.
Claim 8
Dependent Claim
115 words
A cosmetic unit dosage form comprising a soft gelatin capsule containing a substantially water-free liquid blend consisting essentially of: (a) about 0.5-10% fragrance; (b) about 30-60% of a foamable mixture of basic surfactants comprising a fatty acid (diethanol)-amide and a basic surfactant of the formula: (C.sub.8 -C.sub.22)alkyl(OCH.sub.2 CH.sub.2).sub.n OSO.sub.3 H.HN(CH.sub.2 CH.sub.2 OH).sub.2, wherein n is about 1-5; (c) about 30-60% of a foamable acidic surfactant comprising a surfactant of the general formula: (C.sub.8 -C.sub.22)alkyl(OCH.sub.2 CH.sub.2).sub.m OCH.sub.2 CO.sub.2 H, wherein m is about 3-15; and (d) about 2-5% propylene glycol said percentages being percentages by weight based on the total weight of the composition, said composition containing not more than 10% by weight of other components.
