Abstract
Abstract Mixed complex salts of aluminum sulfate and a neutralized salt of an aliphatic alcohol sulfate are prepared. The mixed complex salts are soluble in aqueous solution and have surface active properties. Ethylene oxide can be introduced into the starting alcohol sulfate to obtain a mixed complex aluminum salt which is completely soluble upon any degree of dilution. Unethoxylated salts become insoluble upon dilution at specific dilution points depending on the cation of the neutralized salt used to form the mixed complex salt.
