Abstract

Abstract A two-phase shampoo composition is made by preparing substantially polar and lipophilic portions of a shampoo composition, and mixing them together. As the result of the mixing, the lipophilic portion becomes emulsified and creamy in appearance, forming a lotion which is stable and which is lighter than the polar phase. The lotion floats on top of the polar phase and a sharp line of demarcation is subsequently exhibited between the phases. Apparently, minor proportions of components of the polar phase are absorbed into the lipophilic phase, forming the stable lotion. The polar phase comprises amphoteric and also, cationic surface active agents, including higher alkyl di-lower alkyl amine oxide, N-higher alkyl beta-alanine, higher fatty acid amido-lower alkyl di-lower alkyl hydroxy-lower alkyl ammonium halide, and higher fatty acid di-lower alkanolamide, with lower alcohol, water, and means to adjust the pH to within the range of about 5 to 9.5. The lotion portion comprises a suitable oil, such as a light mineral oil, plus constituents absorbed from the polar phase to form the lotion. Although mineral oil is an important constituent of the lipophilic phase and increases the stability of the resulting product, as compared to vegetable or animal oils and fats which are sometimes employed in shampoos, small proportions of such oils may often be used, in addition to a major proportion of mineral oil in the lotion phase. The shampoo made is used as a homogeneous temporary emulsion of the lotion and polar phase, created by shaking, and imparts a conditioning action to the hair washed with it, due to the actions of the oil, amphoteric and cationic surface active agents and the conditioners in the formula.
