Liquid detergent compositions |
(57) Aqueous surfactant concentrates comprise water and about 30 to 80% by weight of a
surfactant mixture of (a) at least 50% by weight anionic surfactants based on the
weight of the surfactant mixture, including at least 20% alkyl benzene sulphonate
based on the weight of the surfactant mixture, and (b) at least 2%, based on the weight
of the surfactant mixture, of nonionic ethoxylate having an HLB less than 12, the
water being present in an amount adapted to form a spherulitic or lamellar composition.
Liquid detergents contain water, from 5 to 25% by weight of said surfactant mixture
and enough dissolved electrolyte to form a non-sedimenting spherulitic composition.
