example 1

[0052] The composition according to the present invention is prepared as follows: the following ingredients are added to the container one at a time: polyglyceryl-4 isostearate, cetyl alcohol, stearic acid, magnesium stearate, oil. These ingredients are then heated to between 60°C and 75°C while stirring. In a separate beaker, add water, thickener, and pH adjuster when hydrated to obtain a pH of about 6 to about 7. Another thickener, modified hydroxyethyl cellulose is added to the mixture while stirring. When it is uniform, add wetting agent and preservative while heating to 60-75°C. Then the water phase is added to the oil phase while mixing. The composition was cooled to room temperature.
