Abstract
Abstract A dialkyl quaternary ammonium compound falling within the formula ##STR1## wherein R 1 and R 2 are the same or different straight chain alkyl radicals C n H 2n+1 wherein n is predominantly at least 12, and particularly where n equals predominantly 12-16, unexpectedly prevents Ext. D & C Violet No. 2 dye from staining skin while providing better deposition of the Ext. D & C Violet No. 2 onto human hair and wool to decrease or eliminate hair and wool yellowing. These fatty radicals R 1 and R 2 are generally derived from coconut oil, lauric acid, myristic acid, or palmitic acid and An - is any anion, particularly the halogen ions and particularly the chloride ion.
