Abstract
Abstract The present invention relates to a very mild, stable, liquid dispersoidal cleansing composition comprising: 55% to 90% water; 5% to 20% saturated (low IV) higher (high titer) fatty acid potassium soap; 2.5% to 18% of free fatty acids; said soap and said free fatty acids having a ratio of about 1:0.3 to 1:1; and wherein said liquid cleanser has a viscosity of 4,000 cps to about 100,000 cps at about 25 degrees C.; and wherein said liquid cleanser is phase stable. The stable, mild liquid cleanser is preferably contained in a container having a pressure actuated pump. The composition is preferably made by the steps of: 1. heating and mixing an aqueous mixture of said potassium fatty acid soap and said free fatty acid to provide a stable melt; 2. cooling the melt to about room temperature; 3. diluting said cooled melt with water to provide said dispersoidal liquid.
