Hair care compositions and methods for using the same are disclosed herein. According to one aspect of the disclosure, a hair care composition is provided that includes from about 1 to about 20 wt. % of an anionic surfactant; from about 0.5 to about 5 wt. % of an amphoteric surfactant; from about 0.1 to about 7 wt. % of a nonionic surfactant; from about 0.1 to about 5 wt. % of a thickening agent, wherein the thickening agent is a natural gum; and from about 0.05 to about 4.5 wt. % of a silicone wherein the hair composition is an emulsion and all weight percentages are based on the total weight of the hair care composition. Additionally, the hair care composition may have a weight ratio for the total amount of anionic surfactant to the total amount of amphoteric surfactant that is about 5:1 to about 20:1.

Copolymers are formed of monomers of poly(dimethylsiloxane) and poly(alkylene oxide) of the following formula: A.sub.x-XCH.sub.2CH.sub.2—[B.sub.yC.sub.z].sub.n—X-A.sub.x. In the formula, each X independently represents a —CH.sub.2— group or an oxygen atom, A represents a polydimethylsiloxane derivative, B represents a polyethylene glycol unit, C represents a polypropylene glycol unit, x and n independently represent an integer from 1 to 150, and y and z independently represent an integer from 0 to 150. The copolymers can be used as emulsifiers in personal care compositions.

Multi-functional base emulsions that can be used to form a variety of cosmetic compositions are disclosed. In one aspect, a cosmetic emulsion can include a water phase including about 10% to about 67.5% water by total weight of the cosmetic emulsion. The cosmetic emulsion can also include an oil phase that includes (a) stearalkonium hectorite, and (b) a silicone alkyl polyether selected from the group consisting of: PEG/PPG-18/18 dimethicone, PEG/PPG-20/15 dimethicone, and Lauryl PEG/PPG-18/18 dimethicone.
