Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 186 words
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° F. to about 170° F.; (e) injecting the premixes sequentially into the main mix, which is at ambient temperature; and (f) allowing the composition to cool.
Claim 2
Dependent Claim 186 words
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° F. to about 170° F.; (e) injecting the premixes sequentially into the main mix, which is at ambient temperature; and (f) allowing the composition to cool.
Claim 3
Dependent Claim 51 words
A process according to claim 1 wherein the main mix comprises on a total composition basis: (a) from about 5% to about 40% of an anionic surfactant; (b) from 0% up to about 5% perfume; (c) from 0% up to about 5% dye; and (d) from 20% to about 30% water.
Claim 4
Dependent Claim 10 words
A shampoo composition made by the process of claim 1.
Claim 5
Dependent Claim 100 words
A shampoo composition made by the process of claim 1 comprising: (a) from about 5% to about 60% of an anionic surfactant selected from the group consisting of ammonium lauryl sulfate, ammonium laureth sulfate, and mixtures thereof; (b) from about 01% to about 10% polydimethyl siloxane; (c) from about 0.5% to about 5% ethylene glycol distearate; (d) from about 0.1% to about 1% coconut monoethanolamide; (e) from about 1% to about 5% of a hydrotrope; (f) from about 0.01% to about 5% tricetyl methyl ammonium chloride; and (g) from 0.1% to about 5% of an alkyl ethoxylated phosphoric acid monoester.
Claim 6
Dependent Claim 26 words
A shampoo composition according to claim 4 wherein the alkyl ethoxylated phosphoric acid monoester is selected from the group consisting of laureth-3-phosphate, oleth-3-phosphate, laureth-4-phosphate, and laureth-5-phosphate.
