Concentrated aqueous surfactants

Abstract From the Canadian patent

Concentrated surfactant compositions comprise water and from 30 to 55% by weight of surfactant based on the total weight of surfactant and water. The surfactant comprises at least 8% based on the total weight of the composition of at least one anionic surfactant which is capable of forming a 20% L1 micellar solution with a cloud point below 0°C such as an alkyl ether sulphate and preferably at least one other surfactant such as sodium alkyl benzene sulphonate soap and or a, nonionic surfactant. In the absence of electrolyte the composition is a viscous, pourable phase with hexagonal symmetry by x-ray diffraction. Electrolyte forms an optically isotropic clear Newtonian liquid detergent …
