Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
170 words
A shampoo composition comprising (A) 0.1 to 10 percent by weight of a mixture of mono-, di- and tri-acylated fatty acid esters of sucrose having the formula (1) ##STR24## in which R 1 , R 2 and R 3 represent hydrogen or a straight-chain or branched, saturated or unsaturated acyl group having 8 to 24 carbon atoms and the weight ratio of mono-acylated esters to the sum of di- and tri-acylated esters is 70/30 to 30/70, (B) 0.05 to 5 percent by weight of a nonionic cellulose ether compound having the formula (2) ##STR25## in which R 4 , R 5 and R 6 is a hydrogen atom, (CH 2 CH 2 O) m H in which m is 1 to 5, --CH 3 or --C 3 H 6 OH, and n is 100 to 10,000, (C) 5 to 30 percent by weight of a shampoo base comprising one or more members selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants, and (D) water.
Claim 2
Dependent Claim
170 words
A shampoo composition comprising (A) 0.1 to 10 percent by weight of a mixture of mono-, di- and tri-acylated fatty acid esters of sucrose having the formula (1) ##STR24## in which R 1 , R 2 and R 3 represent hydrogen or a straight-chain or branched, saturated or unsaturated acyl group having 8 to 24 carbon atoms and the weight ratio of mono-acylated esters to the sum of di- and tri-acylated esters is 70/30 to 30/70, (B) 0.05 to 5 percent by weight of a nonionic cellulose ether compound having the formula (2) ##STR25## in which R 4 , R 5 and R 6 is a hydrogen atom, (CH 2 CH 2 O) m H in which m is 1 to 5, --CH 3 or --C 3 H 6 OH, and n is 100 to 10,000, (C) 5 to 30 percent by weight of a shampoo base comprising one or more members selected from the group consisting of anionic surfactants, cationic surfactants, nonionic surfactants and amphoteric surfactants, and (D) water.
Claim 3
Dependent Claim

Claim 9
Dependent Claim
18 words
