ABSTRACT:
A shaving preparation is provided that boils above about 50.degree. C. and that rapidly generates a stable shaving lather when rubbed on the skin. The composition is an aqueous soap (a neutralized fatty acid) solution containing a foam generating ingredient, a non-volatile, water-insoluble organic liquid and free fatty acids. Thus, the fatty acids mixture of this invention consists of both free fatty acids and neutralized fatty acids (soap). An unexpected rise in the boiling point occurs when the total fatty acids present are in an amount greater than 11% by weight and where 50 to 85% by weight of the total fatty acids are neutralized fatty acids.
