Abstract
The present invention represents ovicidal/pediculicidal anti-lice active containing compositions containing a combination of alkanol synergizers selected from the group consisting of phenyl C.sub.2 -C.sub.6 alkanols, phenyl C.sub.2 -C.sub.6 diols, and mixtures thereof, with quaternary ammonium salts, long chain (CH.sub.12 -C.sub.22 fatty amines, and mixtures thereof. The compositions include hair care compositions which are storage stable at high temperatures.

A stable ovicidal/pediculicidal active hair conditioning composition comprising:
- (a) from about 0.1% to about 5.0% of a cationic surfactant selected from the group of fatty amines consisting of primary, secondary and tertiary fatty amines having at least one alkyl group with from about 12 to about 22 carbon atoms;
- (b) from about 0.25% to about 5% of an alkanol synergizer selected from the group consisting of phenyl ethanol, phenyl propanol, phenyl ethanediol, and mixtures thereof;
- (c) from about 0.5% to about 5% of naturally and synthetically derived fatty materials selected from the group consisting of acids, alcohols, esters, ethers, ketones, amides, and mixtures thereof having carbon chain lengths of from about 12 to about 22;
- (d) from about 85% to about 95% water.
A hair conditioner form ovicidal/pediculicidal composition comprising:
- (a) from about 0.1% to about 5.0% of a cationic surfactant, the cationic surfactant being a mixture of a fatty amine selected from the group consisting of primary, secondary and tertiary fatty amines having at least one alkyl group with from about 12 to about 22 carbon atoms, and quaternary ammonium salts wherein the quaternary ammonium salts are selected from the group consisting of dicetyl dimethyl ammonium chloride, tricetyl methyl ammonium chloride, ditallow dimethyl ammonium chloride, di(hydrogenated tallow) dimethyl ammonium chloride, stearyl dimethyl benzyl ammonium chloride, cetyl trimethyl ammonium chloride, and mixtures thereof;
- (b) from about 0.25% to about 5% of an alkanol synergizer selected from the group consisting of phenyl ethanol, phenyl propanol, phenyl ethanediol, and mixtures thereof;
- (c) from about 0.5% to about 5% of naturally and synthetically derived fatty materials selected from the group consisting of acids, alcohols, esters, ethers, ketones, amides, and mixtures thereof having carbon chain lengths of from about 12 to about 22;
- and
- (d) from about 85% to about 95% water.
