Patent ID: 7612136

Claim:
An anionic surfactant concentrate, comprising: (a) a compound according to general formula (III): R 1 —O—[CH 2 —CH 2 O] n -A (III) wherein R 1 represents a saturated or unsaturated, branched C 6-22 radical with an average branching of about 2 to about 8 per radical, A represents —SO 3 M, —PO 3 M, —PO 3 M 2 , —OOCCH 2 CH(SO 3 Na)COO—, or HOOCCH 2 CH(SO 3 Na)COO—, M represents a positive counterion, and n represents a value from 0 to about 100; and (b) a compound according to general formula (IV): wherein R 2 represents a saturated or unsaturated C 8-16 radical, each A represents —SO 3 M, —PO 3 M, —PO 3 M 2 , —OOCCH 2 CH(SO 3 Na)COO—, or HOOCCH 2 CH(SO 3 Na)COO—, M represents a positive counterion, and x and y each represent a value from 0 to about 100, wherein the sum of x and y represents a value of at least 1 to 100.
