## Abstract

A shampoo composition and a method of making a shampoo composition which delivers both good conditioning benefits and good lather performance. The shampoo composition comprises a dispersed gel network phase comprising: from about 2.8 weight % to about 8 wt % of one or more fatty alcohols; at least 0.01% of one or more secondary surfactants, wherein the secondary surfactant comprises sodium laureth-n sulfate wherein n is from about 0 to about 5; and water; and from about 5% to about 50% of a detersive surfactant; from about 0.02% to about 1.50% of a material selected from the group consisting of structurants, suspending agents and mixtures thereof, from about 0.5 to about 1% of a cationic deposition polymer; and at least 20% of an aqueous carrier.

iii. water; and
b. from about 5% to about 50% of a detersive surfactant, by weight of said shampoo composition;
c. from about 0.5% to about 2% of a co-surfactant; wherein the co-surfactant is selected from a betaine, a sultaine, a cocomonethanolamine, and mixtures thereof; by weight of said shampoo composition
d. from about 0.02% to about 1.50% of a material, by weight of said shampoo composition, selected from the group consisting of structurants, suspending agents and mixtures thereof;
e. from about 0.5 to about 1% of a cationic deposition polymer, by weight of said shampoo composition; wherein the polymer has a about 0.7 meq/g and weight average molecular weight greater than about 1,000,000;
f. at least 20% of an aqueous carrier, by weight of said shampoo composition;
wherein said shampoo composition has:
a. a zero shear viscosity that is greater than 30,000 cps;
b. a bubble count half life that is greater than 120 seconds, as measured by the Kruss DFA100; and
c. a final bubble count per mm2 that is greater than 60.

### Claim 2

A method of making a shampoo composition comprising:
a. forming a dispersed gel network phase by combining
i. from about 3.5 weight % to about 8 wt % of one or more fatty alcohols, by weight of said shampoo composition; wherein the fatty alcohol is selected from cetyl alcohol, stearyl alcohol, or mixtures thereof;
ii. at least 0.01% of one or more secondary surfactants by weight of said shampoo composition, wherein the secondary surfactant comprises sodium laureth-n sulfate wherein n is from about 0 to about 5; and
iii. water; and
b. mixing the dispersed gel network phase into a shampoo base comprising:
i. from about 5% to about 50% of a detersive surfactant by weight of said shampoo composition;
ii from about 0.02% to about 1.50% of hydrogenated castor oil by weight of said shampoo composition;
