ABSTRACT:
A high concentration surfactant slurry, containing at least 50 wt. % of a higher alcohol ethoxylate sulfate salt, is provided. This slurry has incorporated therein a polyoxyethylene alkyl ether having an average molecular weight of about 4,000 to 10,000 and an alkyl group of 8-16 carbon atoms. The slurry has a reduced viscosity and is not affected by the temperature, with the result that it can be handled easily at low temperatures. It also exhibits no phase separation, even when it is stored over a long period of time.
