Low silicone hair conditioning shampoo and non-silicone hair conditioning/style control shampoo
First Claim
1. A hair conditioning shampoo composition comprising, by weight, an aqueous dispersion of:
- a) about 1% to about 16% of a water-insoluble lipid phase comprising a long chain aliphatic alcohol having an average of from about 24 to about 50 carbon atoms and from 0 to about 40 ethoxy units;
b) at least about 0.7% of a water-insoluble, monocationic conditioner compound dissolved in said lipid phase, said monocationic compound being selected from the group consisting of an alkyl amine having a pKa of at least 7.5 selected from the group consisting of distearylamine, distearyl methylamine, behenylamine, behenylmethylamine, behenyldimethylamine, dicetylamine, dicetylmethylamine and tricetylamine;
c) about 3% to about 25% of a water-soluble, anionic, hair cleansing organic surfactant;
d) an amphoteric betaine or sulfobetaine surfactant containing a C8 -C18 alkyl or C8 -C18 alkanolamido C2 -C3 alkylene group in its molecular structure, present in said dispersion at a level of at least 0.75 to 1.25 parts by weight per one part by weight of said anionic surfactant;
e) from 0 to about 6% of a water-insoluble, non-volatile silicone hair conditioning agent; and
f) 0.2% to 3% of at least one hair conditioning, water-soluble, film-forming polycationic polymer;
the weight ratio of said monocationic conditioner compound to said lipid compound in said lipid phase being in the range of from about 5;
1 to about 1;
10 and the molar ratio of anionic surfactant to water-insoluble, monocationic compound being in the range of 2;
1 to 50;

Abstract
A mild, non-irriatating hair conditioning shampoo is disclosed comprising an aqueous dispersion of a water-insoluble lipid phase, an anionic hair cleansing surfactant, an amphoteric surfactant present at a level of at least about 0.75 parts by weight per part by weight of said anionic surfactant, at least one hair conditioning, film forming, polycationic polymer soluble in the aqueous dispersion and 0-6% by weight, based on the weight of the shampoo, of a water-insoluble, non-volatile hair conditioning silicone, the water-insoluble lipid phase comprising at least one lipid soluble, emulsifiable, monocationic, quaternary ammonium compound or amine solubilized in a water-insoluble long chain lipid compound, the weight ratio of monocationic compound to the lipid compound in the lipid phase being in the range of from about 5:1 to about 1:10 and the molar ratio of anionic surfactant to water-insoluble cationic compound is greater than 2:1. The shampoo having no silicone possesses a high degree of style control properties. The shampoo containing silicone has a high degree of hair conditioning properties.
