  • Process for preparing soap-acyl isethionate compositions
    Patent number: 5041233
    Abstract: A batch and continuous process is disclosed for the production of a composition comprising alkali metal salts of C.sub.8 -C.sub.22 alkyl fatty monocarboxylic acid and C.sub.8 -C.sub.22 acyl isethionate in a ratio of 20:1 to 1:0.98. Both batch and continuous routes require that the saponifying aqueous caustic solution includes sodium hydroxide and sodium isethionate maintained as a hot solution at a temperature of from 180.degree. F. to about 200.degree. F. For the batch route, the sequence of steps require the caustic solution to be added slowly to the fatty acid. In the continuous process, it is advantageous to introduce fatty acid upstream from the point where the caustic solution stream enters the mixing chamber.

  • Acyl isethionate skin cleansing compositions
    Patent number: 4954282
    Abstract: A skin cleansing composition is provided that includes a combination of C.sub.16 -C.sub.18 acyl isethionate ester salts having no more than 25% C.sub.14 or lower acyl groups with at least one co-active surfactant. The weight ratio of acyl isethionate to co-active will range from about 20:1 to about 1:1. Soap is present in an amount no higher than 10% by weight of the composition.
