Patent ID: 8222197

Claim:
A fluid detergent composition comprising: a) from 1% to 70% by weight of a surfactant selected from the group: anionic, nonionic surfactants and mixtures thereof; and b) from 0.01 wt % to 10 wt % of a pH tuneable amido-gellant as an external structuring system having a formula wherein: at least one of L 1 , R 1 or R 2 comprises a pH-sensitive group; L 1 is a backbone moiety having molecular weight from 14 to 500 g/mol; and R 1 is R 3 or R 2 is R 4 or wherein each AA is independently selected from the group consisting of: and R 3 and R 4 independently have the formula: (L′) o -(L″) q -R, wherein: (o+q) is from 1 to 10; L′ and L″ are independently selected from the group consisting of: and R, R′ and R″ are independently selected either from pH-sensitive-groups consisting of: wherein n and m are integers from 1 to 20; or from non-pH-sensitive groups consisting of: such that at least one of R, R′ and R″ comprises a pH-sensitive group; wherein the pH tuneable amido-gellant has a pKa of from 1 to 30.
