Patent number: 4181634Abstract: Mild cleansing compositions comprising at least one detergent and at least one alkyleneoxylated bisquaternaryammonium compound are described. Suitable bisquaternary ammonium compounds are represented by the formula ##STR1## wherein R is an aliphatic radical of from about 10 to about 26 carbon atoms, R' is methyl, ethyl, propyl or R, X is an anion, n is an integer from 2 to 3, and x is an integer of from 1 to about 30. Suitable detergents are anionic or amphoteric detergents. The addition of alkyleneoxylated bisquaternary ammonium compound to anionic and amphoteric detergents reduces the irritant properties of the detergents.Type: GrantFiled: May 5, 1978Date of Patent: January 1, 1980Assignee: Johnson & JohnsonInventors: Robert R.
