  • Hair conditioning composition and method
    Patent number: 4719104
    Abstract: A human hair conditioner and methods are disclosed. The conditioner consists essentially of an aqueous composition containing 0.25-4 percent static-reducing agent, 0.05-1.0 percent cationic film-forming polymer that contains a plurality of quaternary nitrogen atoms, and 0.25-4 percent distearyldimethylammonium salt, wherein the weight ratio of the static-reducing agent to the cationic polymer is about 2:1 to about 20:1.

  • Dye-conditioner composition that is non-staining to skin containing a certified violet dye and a quaternary ammonium compound
    Patent number: 4678475
    Abstract: A dialkyl quaternary ammonium compound falling within the formula ##STR1## wherein R.sup.1 and R.sup.2 are the same or different straight chain alkyl radicals C.sub.n H.sub.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.sup.1 and R.sup.2 are generally derived from coconut oil, lauric acid, myristic acid, or palmitic acid and An.sup.- is any anion, particularly the halogen ions and particularly the chloride ion.
