Abstract
The invention discloses process for making bars comprising fatty acid soaps, free fatty acid, polyalkylene glycol and specific salts of protic acid (i.e., having pKa1 less than 6, preferably less than 5.5). Using specific equivalent molar ratios of fatty acid to protic acid salt and specific wt. ratio of PAG and salt of protic acid to free fatty acid, applicants obtain bars having sensory feel of soap and which improve skin condition in Controlled Application Wash Tests.
