Abstract
An improved process for making silicone containing shampoo wherein heated premixes are added to a main mix at ambient temperature.
Claims5
A process for making a slicone-containing shampoo composition comprising the steps of:
- (a) preparing a first premix comprising:
- (i) from about 0.5% to about 5% ethylene glycol distearate;
- (ii) from about 1% to about 10% of an anionic surfactant;
- (iii) from about 0.1% to about 5% of a viscosity modifier;
- (iv) from about 0.1% to about 5% cocomonoethanol amide;
- and
- (v) from about 1% to about 10% water;
- (b) preparing a second premix comprising:
- (i) from about 0.01% to about 10% of a silicone conditioning agent;
- (ii) from about 0.1% to about 5% ammonium xylene sulfonate;
- (iii) from about 0.01% to about 5% cetearyl alcohol;
- (iv) from about 0.01% to about 5% tricetyl methyl ammonium chloride;
- (v) from about 1% to about 10% of an anionic surfactant;
- and
- (vi) from 0.3% to about 3% xanthan gum.
- (c) preparing a main mix comprising all other desired ingredients, including adjuvants;
- (d) heating the premixes separately to a temperature of from about 150.degree. F. to about 170.degree. F.;
- (e) injecting the premixes sequentially into the main mix, which is at ambient temperature;
- and
- (f) allowing the composition to cool.
