Abstract
Abstract A single liquid phase detergent composition, such as a foam bath product, contains a cosmetically acceptable oil as a skin benefit agent and a mixture of anhydrous anionic detergents. In use, when diluted in water, the composition is capable of producing and maintaining a substantial head of foam and is capable of depositing on the skin after immersion a noticeable amount of the oil.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
128 words
A single liquid phase detergent composition comprising: (i) from 15 to 50% by weight of a cosmetically acceptable oil; (ii) from 40 to 75% by weight of an anionic detergent mixture comprising (a) an anhydrous amine salt of a C 8 to C 18 fatty alcohol sulphate containing an average of from 0 to 4 moles of ethylene oxide; and (b) an anhydrous alkyl or alkylaryl substituted ethoxylated oxacarboxylic acid or a sodium or an amine salt thereof having the empirical formula: R--(OCH.sub.2 CH.sub.2).sub.n --OCH.sub.2 COOX where R is C 8 to C 18 alkyl or C 6 to C 12 alkylphenyl; n has an average value of from 1 to 15; and X is hydrogen, sodium or an amine residue; and (iii) from 0 to 5% water.
Claim 2
Dependent Claim
128 words
A single liquid phase detergent composition comprising: (i) from 15 to 50% by weight of a cosmetically acceptable oil; (ii) from 40 to 75% by weight of an anionic detergent mixture comprising (a) an anhydrous amine salt of a C 8 to C 18 fatty alcohol sulphate containing an average of from 0 to 4 moles of ethylene oxide; and (b) an anhydrous alkyl or alkylaryl substituted ethoxylated oxacarboxylic acid or a sodium or an amine salt thereof having the empirical formula: R--(OCH.sub.2 CH.sub.2).sub.n --OCH.sub.2 COOX where R is C 8 to C 18 alkyl or C 6 to C 12 alkylphenyl; n has an average value of from 1 to 15; and X is hydrogen, sodium or an amine residue; and (iii) from 0 to 5% water.
Claim 3
Dependent Claim
17 words
