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. |
