Abstract:
A detergent composition comprising a surfactant mixture, the surfactant mixture containing:(a) a nonionic surfactant corresponding to formula (I): R1O(CH2CH2O)nHâ€ƒâ€ƒ(I) â€ƒwherein R1 is a hydrocarbon radical having from about 16 to 18 carbon atoms and n is a number from about 5 to 10, and wherein the nonionic surfactant has an iodine value of from about 20 to 50, and a carbon chain length distribution corresponding to: (i) from about 55 to 65% by weight of C16 saturated; (ii) from about 2 to 10% by weight of C18 saturated; (iii) from about 25 to 30% by weight of C18 monounsaturated; and (iv) from about 1 to 5% by weight of C18 di-unsaturated, with the proviso that the amounts, together with small amounts of shorter-chain and/or longer-chain homologues, added up to 100% by weight; and (b) a co-surfactant selected from the group consisting of an alkyl oligoglycoside, an alkenyl oligoglycoside, an alkyl ether sulfate, and mixtures thereof.
