Abstract

Disclosed are shampoo compositions comprising a silicone emulsion comprising a silicone polymer selected from the group consisting of a polyalkyl siloxane having a molecular weight of at least 20,000, a polyaryl siloxane having a molecular weight of at least 20,000, and amino-substituted siloxane having a molecular weight of at least 5,000, a silicone resin having a molecular weight of at least 5,000, and mixtures thereof, an anionic surfactant, a compatibilizing surfactant, and a cationic surfactant, Wherein the silicone polymer is dispersed as a particle having an average size of not more than 450 nm; a detersive surfactant; a conditioning agent; and water: wherein the composition is substantially free of silicone suspending agents.

Claims

1. A shampoo composition comprising by weight:

(a) a silicone emulsion comprising;

i) from about 0.01% to about 20% of the entire composition a silicone polymer selected from the group consisting of a polyalkyl siloxane having a molecular weight of at least 20,000, a polyaryl siloxane having a molecular weight of at least 20,000, an amino-substituted siloxane having a molecular weight of at least 5,000, a silicone resin having a molecular weight of at least 5,000, and mixtures thereof;

ii) an anionic surfactant;

iii) a compatibilizing surfactant; and

iv) a cationic surfactant;

wherein the silicone polymer is dispersed as a particle having an average size of not more than about 450 nm;

(b) from about 5% to about 50% of a detersive surfactant;

(c) from about 0.1% to about 20% of a conditioning agent; and

(d) water;

wherein the composition is substantially free of acyl derivative silicone suspending agents.

2. The shampoo composition according to claim 1 wherein the silicone polymer is selected from the group consisting of a dimethiconol having a molecular weight of at least 100,000, an amodimethicone having a molecular weight of at least 10,000, and mixtures thereof.

3. The shampoo composition according to claim 1 wherein the silicone emulsion comprises the silicone polymer dispersed as a particle having an average size of from about 150 nm to about 250 nm.
