Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
97 words
A shampoo composition containing at least two amphoteric surfactants of the general formula (I) where R is a C 8-20 hydrocarbyl group, optionally substituted; R 1 is H or C 1-6 alkyl; B is H, alkyl or substituted alkyl, or a group Q as defined below; Q is an anionic moiety; x is 2 to 6; y is 0 to 5; z is 0 or 1; and n is 0 or 1 (z being 0 when n is 1); the composition containing at least one of surfactant of general formula (1) above in which z is 0
Claim 2
Dependent Claim
97 words
A shampoo composition containing at least two amphoteric surfactants of the general formula (I) where R is a C 8-20 hydrocarbyl group, optionally substituted; R 1 is H or C 1-6 alkyl; B is H, alkyl or substituted alkyl, or a group Q as defined below; Q is an anionic moiety; x is 2 to 6; y is 0 to 5; z is 0 or 1; and n is 0 or 1 (z being 0 when n is 1); the composition containing at least one of surfactant of general formula (1) above in which z is 0
Claim 3
Dependent Claim
27 words
A composition according to claim 1 which contains a first amphoteric surfactant in which z is 0 and a second amphoteric surfactant in which z is 1.
Claim 4
Dependent Claim
39 words
A composition according to claim 1 which contains a first amphoteric surfactant in which z is 1 and y is 0 or 1, and a second amphoteric surfactant in which z is 0 and y is 2 to 5.

Claim 7
Dependent Claim
35 words
A composition according to claim 1 which contains 95-50% of surfactant(s) in which z is 1 and 5-50% of surfactant(s) in which z is 0, by weight based on the total weight of said surfactants.
Claim 8
Dependent Claim
