Abstract
The present invention relates to an improved freezer bar soap comprising selected saturated C.sub.14 -C.sub.18 fatty acid soaps and lathering soap selected from lauric, oleic, and other minor selected more soluble soaps. The bars of this invention have improved mildness while maintaining acceptable lathering/sudsing characteristics.
Claims12
A mild, lathering personal cleansing freezer soap bar comprising:
- I. saturated fatty acid soaps selected from the group consisting of:
- myristic, palmitic, and stearic acid soaps and mixtures thereof at a level of from about 65% to about 85% by weight of total fatty acid soap;
- and
- II. from about 15% to about 35% of soap selected from the group consisting of:
- oleic and lauric acid soaps and minor fatty acid soap selected from the group consisting essentially of:
- C.sub.8, C.sub.10, C.sub.18:2 and mixtures thereof;
- wherein said bar contains from about 8% to about 25% of said selected oleic and lauric soap, and minor soaps;
- wherein said oleic soap level is from 0% to about 25% by weight of the bar;
- and
- said lauric soap is from 0% to about 10% by weight of said bar;
- and
- wherein said minor (C.sub.8, C.sub.10, C.sub.18:2) soap level is from 0% to about 5% by weight of said bar;
- and
- wherein said selected lauric/oleic soap to said minor (C.sub.8, C.sub.10, C.sub.18:2) soap have a ratio of from about 1:1 to about 1:0;
- and
- wherein said soap is a mixture of sodium and potassium soap (Na/K);
- and
- wherein said Na/K soap mixture level is from about 90% to about 100% by weight of said total soap;
- and
- wherein said Na/K soap has a ratio of from about 19:1 (95/5) to about 1.5:1 (60/40);
- and
- wherein said freezer soap bar comprises from about 30% to about 70% of total fatty acid soap by weight of said bar;
- and
- III. from about 15% to about 30% of water by weight of said bar.
