example 1

[0057] The composition according to the invention is prepared as follows: the following ingredients are added to a container one at a time: polyglyceryl-4 isostearate, cetyl alcohol, stearic acid, magnesium stearate, Oil. The ingredients are then heated to between 60°C and 75°C while stirring. In a separate beaker, add water, thickener, and when hydrated, pH adjuster to obtain a pH of about 6 to about 7. Another thickener, modified hydroxyethyl cellulose, was added to the mixture with stirring. When uniform, add wetting agent and preservative while heating to 60-75°C. The water phase is then added to the oil phase while mixing. The composition was cooled to room temperature.
