Claims12
A personal cleansing bar composition essentially free of raw material malodors comprising:
- A. an odor-controlling amount of intermediate ratio (SiO.sub.2 :Al.sub.2 O.sub.3)Y zeolite;
- B. from about 4% to about 32% of essentially saturated long chain (C.sub.15 -C.sub.22 alkyl) synthetic surfactant selected from the group consisting of:
- alkyl sulfate, acyl isethionate, alkyl sarcosinate, alkyl glyceryl ether sulfonate, and mixtures thereof;
- C. from about 4% to about 30% of paraffin wax having a melting point of from about 130.degree. F./54.degree. C. to about 180.degree. F./82.degree. C.;
- D. from about 20% to about 70% lathering mild synthetic surfactant;
- and wherein said lathering mild synthetic surfactant is selected from C.sub.12 -C.sub.18 acyl isethionate, C.sub.12 -C.sub.14 alkyl glyceryl ether sulfonate, C.sub.12 -C.sub.18 acyl sarcosinate, and mixtures thereof and wherein at least about 10% of said bar is said mild lathering C.sub.12 -C.sub.18 acyl isethionate;
- E. from about 2% to about 30% free fatty acid;
- F. from 0% to about 15% soap;
- G. from about 2% to about 8% sodium isethionate;
- H. from 0% to about 2% sodium chloride;
- I. from about 1.5% to about 10% water;
- and
- J. from 0% to about 5% of a polymer.
