Abstract
A very stable mild soap personal cleansing and moisturizing composition comprising: C.sub.8 -C.sub.22 free fatty acid soap, C.sub.8 -C.sub.22 free fatty acid, water, and petrolatum, preferably having a weight average particle size larger than 45 microns.
Claims7
A solid cleansing bar composition, by weight, consisting essentially of:
- (A) 5 parts to 75 parts saturated fatty acid material consisting of a mixture of C.sub.8 -C.sub.22 free fatty acid and C.sub.8 -C.sub.22 fatty acid soap;
- (B) 10 parts to 90 parts water;
- (C) 0.5 parts to 35 parts petrolatum having a particle size distribution of from 5 to 120 microns, at least about 20% of the particles having a particle size greater than 10 microns;
- and
- (D) a mild lathering synthetic surfactant;
- and
- wherein said mild lathering synthetic surfactant and said saturated fatty acid material have a ratio of from about 2:1 to about 1:2.

A method of making a solid cleansing bar composition, by weight, comprising:
- (A) 5 parts to 75 parts saturated fatty acid material consisting of a mixture of C.sub.8 -C.sub.22 free fatty acid and C.sub.8 -C.sub.22 fatty acid soap;
- (B) 10 parts to 90 parts water;
- (C) 0.5 parts to 35 parts petrolatum having a particle size distribution of from 5 to 120 microns, at least about 20% of the particles having a particle size greater than 10 microns;
- and
- (D) a mild lathering synthetic surfactant;
- and
- wherein said mild lathering synthetic surfactant and said saturated fatty material have a ratio of from about 2:1 to about 1:2, said method comprising:
- (1) heating and mixing said free fatty acid to provide a stable melt;
- (2) forming soap in situ by adding aqueous sodium hydroxide to provide a heated mix;
- (3) adding said mild synthetic surfactant to said heated mix;
- (4) adding said petrolatum to said heated mix of (3) using low shear and minimal mixing time to provide a homogeneous mix;
- (5) pouring the heated homogeneous mix of (4) into bar molds and cooling to provide said solid cleansing bar composition.
