Abstract
A cleansing bar includes (a) from about 20% to about 35%, by weight of all ingredients in the cleansing bar, a synthetic detergent, sodium cocoyl isethionate, (b) from about 6% to about 11%, by weight of all ingredients in the cleansing bar, cetyl alcohol, wherein a mole to mole ratio of (a) to (b) is at least about 2.2:1, (c) at least about 30%, by weight of all ingredients in the cleansing bar, processed grain, (d) a buffer for adjusting the pH of the cleansing bar to be in a range from about 4.0 to about 5.5, and (e) from about 9% to about 20%, by weight of all ingredients in the cleansing bar, water. Also disclosed are methods of making such a cleansing bar.

A cleansing bar consisting essentially of:
- (a) from about 20% to about 35%, by weight of all ingredients of said cleansing bar, of a synthetic detergent, sodium cocoyl isethionate;
- (b) from about 6% to about 11%, by weight of all ingredients of said cleansing bar, of cetyl alcohol, wherein a mole to mole ratio of (a) to (b) is at least about 2.2:1;
- (c) at least about 30%, by weight of all ingredients of said cleansing bar, of processed grain;
- (d) a buffer for adjusting the pH of said cleansing bar to be in a pH range from about 4.0 to about 5.5;
- and
- (e) from about 9% to about 20%, by weight of all ingredients of said cleansing bar, of water,
- wherein the ingredients in (a) through (e) are combined into said cleansing bar.
A cleansing bar consisting essentially of:

- (b) from about 6% to about 11%, by weight of all ingredients of said cleansing bar, of cetyl alcohol, wherein a mole to mole ratio of (a) to (b) is at least about 2.2:1;
- (c) at least about 30%, by weight of all ingredients of said cleansing bar, of processed grain;
- (d) a buffer for adjusting the pH of said cleansing bar to be in a pH range from about 4.0 to about 5.5;
- (e) from about 9% to about 20%, by weight of all ingredients of said cleansing bar, of water;
- and
- (f) at least one of hardened vegetable shortening and hydrogenated vegetable oil,
- wherein the ingredients in (a) through (f) are combined into said cleansing bar.
A method of making a cleansing bar, said method comprising the steps of:
- (a) mixing together glycerin, water, and preservatives;
- (b) mixing together processed grain and sodium cocoyl isethionate;
- (c) combining together the mixture formed in step (a) and the mixture formed in step (b);
- (d) adding cetyl alcohol to the mixture formed in step (c);
- (e) adjusting the pH of the mixture formed in step (d) by combining a buffer therewith;
- (f) extruding and pressing the mixture formed in step (e) to form a cleansing bar,
- wherein processed grain is present in an amount of at least about 30 wt % of all ingredients of the cleansing bar, sodium cocoyl isethionate in an amount of about 20 to about 35 wt % of all ingredients of the cleansing bar, cetyl alcohol in an amount of about 6 to about 11 wt % of all ingredients of the cleansing bar, and water in an amount of about 9 to about 20 wt % of all ingredients of the cleansing bar, and a mole to mole ratio of sodium cocoyl isethionate to cetyl alcohol is at least about 2.2:1.
A method of making a cleansing bar, said method comprising the steps of:
- (a) mixing, while heating so as to melt, hardened vegetable shortening, hydrogenated vegetable oil, and cetyl alcohol;
- (b) mixing the mixture of step (a) together with sodium cocoyl isethionate;
- (c) mixing the mixture of step (b) together with processed grain;
- (d) adjusting the pH of the mixture of step (c) by combining a buffer therewith;
- (e) extruding and pressing the mixture formed in step (d) to form a cleansing bar,
- wherein, processed grain is present in an amount of at least about 30 wt % of all ingredients of the cleansing bar, sodium cocoyl isethionate in an amount of about 20 to about 35 wt % of all ingredients of the cleansing bar, cetyl alcohol in an amount of about 6 to about 11 wt % of all ingredients of the cleansing bar, and water in an amount of about 9 to about 14 wt % of all ingredients in the cleansing bar, and a mole to mole ratio of sodium cocoyl isethionate to cetyl alcohol is at least about 2.2:1.
