Abstract

Abstract The present invention relates to liquid dispersoidal cleansing compositions comprising: 55% to 90% water; 5% to 20% saturated (low IV) higher (high titer) fatty acid potassium soap; 3% to 18% of free fatty acids; said soap and said free fatty acids having a ratio of about 1:0.5 to 1:1; and wherein said liquid cleanser has a viscosity of 4,000 cps to about 100,000 cps at about 25 DEG C.; and wherein said liquid cleanser is phase stable.
