Abstract
An aqueous foam producing personal cleansing composition is disclosed. The composition, which is normally clear and is essentially free of any amides of diethanolamine, comprises a cloud point depressing agent comprising ammonium chloride. The composition of the present invention is characterized by a low cloud point temperature such that the risk of forming an undesirable precipitate in the composition is reduced. Also disclosed is a method of reducing the cloud point temperature in a normally clear aqueous personal cleansing composition which is essentially free of amides of diethanolamine. The method comprises adding ammonium chloride to the composition.
