Abstract

A cleansing bar comprising at least one member chosen from clay and talc, wherein a total amount of clay and talc is present in an amount that is greater than any other material in the cleansing bar, at least one cleanser chosen from soap and surfactant, and a binder present in an amount to structure the cleansing bar into a bar.

First claim

What is claimed is:

1. A cleansing bar comprising:
clay, wherein a total amount of clay is present in an amount that is greater than any other material in the cleansing bar, and the total amount of clay is at least 40 weight % of the cleansing bar, wherein the clay is at least one clay chosen from kaolin, kaolinite, dickite, halloysite, nacrite, smectite, montmorillonite, nontronite, illite, bentonite, attapulgite, palygorskite, sepiolite, hormite, pyrophyllite, chlorite, and aluminosilicates, and wherein the clay excludes talc,
a cleanser consisting essentially of a surfactant, wherein the surfactant is present in an amount of 5 to 25 weight % of the cleansing bar,
at least one of palm kernel oil and hydrogenated soybean oil, and
at least one binder chosen from paraffin, polymethylene wax, and polyethylene wax, present in an amount to structure the cleansing bar into a bar and present in an amount of at least 1 weight % of the cleansing bar,
wherein either soap is not present in the cleansing bar or soap is present in an amount of less than 0.5 weight % of the cleansing bar.

2. The cleansing bar of claim 1 , wherein the total amount of clay is at least 50 weight % of the cleansing bar.

3. The cleansing bar of claim 1 , wherein the surfactant comprises an anionic surfactant.

4. The cleansing bar of claim 1 , wherein the surfactant comprises at least one surfactant chosen from sodium cocoyl methyl isethionate and sodium laureth sulfate.

5. The cleansing bar of claim 1 , wherein the binder comprises polyethylene wax.

6. The cleansing bar of claim 1 , wherein the binder is present in an amount of at least 2 weight % of the cleansing bar.

7. The cleansing bar of claim 1 , wherein the cleansing bar comprises: 40 to 60 weight % clay, 12 to 20 weight % cleanser consisting essentially of a surfactant, 4 to 5 weight % hydrogenated soybean oil, and 2 to 3 weight % palm kernel oil.

8. The cleansing bar of claim 1 , wherein the cleansing bar comprises 40 to 50 weight % clay, 10 to 15 weight % cleanser consisting essentially of a surfactant, and 10 to 15 weight % binder.

9. The cleansing bar of claim 1 further comprising glycerin.

10. The cleansing bar of claim 1 , wherein the cleansing bar has a slough (weight loss %) less than 20%.

11. A method of making the cleansing bar of claim 1 comprising mixing the clay with the at least one binder before mixing in the cleanser consisting essentially of a surfactant.

12. A method of removing bacteria from skin comprising washing skin with a cleansing bar comprising:
clay, wherein a total amount of clay is present in an amount that is greater than any other material in the cleansing bar, and the total amount of clay is at least 40 weight % of the cleansing bar, wherein the clay is at least one clay chosen from kaolin, kaolinite, dickite, halloysite, nacrite, smectite, montmorillonite, nontronite, illite, bentonite, attapulgite, palygorskite, sepiolite, hormite, pyrophyllite, chlorite, and aluminosilicates, and wherein the clay excludes talc,
a cleanser consisting essentially of a surfactant, wherein the surfactant is present in an amount of 5 to 25 weight % of the cleansing bar,
at least one of palm kernel oil and hydrogenated soybean oil, and
at least one binder chosen from paraffin, polymethylene wax, and polyethylene wax, present in an amount to structure the cleansing bar into a bar and present in an amount of at least 1 weight % of the cleansing bar,
wherein either soap is not present in the cleansing bar or soap is present in an amount of less than 0.5 weight % of the cleansing bar.

13. A method of inhibiting bacterial growth on skin comprising washing skin with a cleansing bar comprising:
clay, wherein a total amount of clay is present in an amount that is greater than any other material in the cleansing bar, and the total amount of clay is at least 40 weight % of the cleansing bar, wherein the clay is at least one clay chosen from kaolin, kaolinite, dickite, halloysite, nacrite, smectite, montmorillonite, nontronite, illite, bentonite, attapulgite, palygorskite, sepiolite, hormite, pyrophyllite, chlorite, and aluminosilicates, and wherein the clay excludes talc,
a cleanser consisting essentially of a surfactant, wherein the surfactant is present in an amount of 5 to 25 weight % of the cleansing bar,
at least one of palm kernel oil and hydrogenated soybean oil, and
at least one binder chosen from paraffin, polymethylene wax, and polyethylene wax, present in an amount to structure the cleansing bar into a bar and present in an amount of at least 1 weight % of the cleansing bar,
wherein either soap is not present in the cleansing bar or soap is present in an amount of less than 0.5 weight % of the cleansing bar.

14. The cleansing bar of claim 4 further comprising at least one surfactant chosen from cocamidopropyl betaine and cocomonoethanolamide.

15. The cleansing bar of claim 1 , wherein the cleansing bar contains less than 8 weight % of fatty material based on the weight of the cleansing bar.
