Evaluation of the displacement of the superfatting agent in soft soaps

Abstract

The metathesis that occurs in soaps superfatted with fatty acids is studied, verified and evaluated. The analysis deals with soaps in solution (shaving creams), in which the problem is showed clearly due to the hydrolysis of the soap. The study is concern on the main fatty acids of the analyzed samples. Knowing the fatty acids distribution, the expected theoretical concentrations of the fatty acids were estimated and were compared with those found by Gas Chromatography.
