Abstract
Personal cleansing bars having a relatively high moisture content are made by forming a soap composition comprised of a neutralized tallow-free fatty acid mixture having an iodine value of less than about 7 and an alkyl polyglycoside of the formula I R.sub.1 O(Z).sub.a I wherein R.sub.1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; Z is saccharide residue having 5 or 6 carbon atoms; a is a number having a value from 1 to about 6. The soap composition is then finished to produce a bar having from about 15% to about 30% by weight of water.

A process for making a personal cleansing bar having a high moisture content comprising the steps of:
- (1) forming a soap composition comprised of from about 80 to about 99% by weight of a neutralized tallow-free fatty acid mixture and from about 1 to about 20% by weight of an alkyl polyglycoside of the formula I
- R.sub.1 O(Z).sub.a I
- wherein R.sub.1 is a monovalent organic radical having from about 6 to about 30 carbon atoms;
- Z is saccharide residue having 5 or 6 carbon atoms;
- a is a number having a value from 1 to about 6, wherein said tallow-free fatty acid mixture has an iodine value of less than about 7 and wherein the above percentages are based on the total weight of the fatty acid mixture and the alkyl polyglycoside;
- (2) finishing said soap composition to produce said bar having from about 15% to about 30% by weight of water.
A process for making a personal cleansing bar having a high moisture content comprising the steps of:
- (1) forming a soap composition comprised of:
- (a) from about 80 to about 99% by weight of a neutralized tallow-free fatty acid mixture;
- (b) a surfactant selected from the group consisting of an anionic, nonionic, cationic, amphoteric surfactant, and a mixture thereof;
- and (c) from about 1 to about 20% by weight of an alkyl polyglycoside of the formula I
- R.sub.1 O(Z).sub.a I
- wherein R.sub.1 is a monovalant organic radical having from about 6 to about 30 carbon atoms, Z is saccharide residue having 5 or 6 carbon atoms;
- a is a number having a value from 1 to about 6;
- wherein said tallow-free fatty acid mixture has an iodine value of less than about 7;
- wherein the above percentages are based on the total weight of the fatty acid mixture and the alkyl polyglycoside;
- and (2) finishing said soap composition to produce said bar having from about 15% to about 30% by weight of water.
A process for making a personal cleansing bar having a high moisture content comprising the steps of:
- (1) forming a soap composition by mixing:
- (a) a first base having a moisture content of from about 15% to about 30% by weight and which is comprised of a neutralized tallow-free fatty acid mixture and an alkyl polyglycoside of the formula I
- R.sub.1 O(Z).sub.a I
- wherein R.sub.1 is a monovalent organic radical having from about 6 to about 30 carbon atoms;
- Z is saccharide residue having 5 or 6 carbon atoms;
- a is a number having a value from 1 to about 6, wherein said tallow-free fatty acid mixture has an iodine value of less than about 7;
- and, (b) a second base having a moisture content of less than about 15% and which is comprised of neutralized tallow/coco fatty acid;
- (2) finishing said soap composition to produce said bar having from about 15% to about 30% by weight of water;
- wherein the neutralized tallow-free fatty acid mixture and the neutralized tallow/coco fatty add are present in a total quantity of from about 80 to about 99% by weight, and the alkyl polyglycoslde is present in from about 1 to about 20% by weight, the above percentages being based on the total weight of neutralized tallow-free fatty acid mixture, neutralized tallow/coco fatty acid, and alkyl polyglycoside.
