Abstract

A soap bar composition comprising solid soap and an oil-in-water emulsion, wherein the emulsion comprises one or more surfactants and wherein the emulsion is dispersed within the solid soap.

First claim

What is claimed is:

1. A soap bar composition comprising solid soap and an oil-in-water emulsion,
wherein the emulsion comprises oil, one or more surfactants, and emulsion water,
wherein a ratio of the oil to the one or more surfactants is from 0.33:1 to 0.67:1,
wherein the emulsion water is present in the emulsion in an amount of at least 95% by weight of the emulsion,
wherein the emulsion is dispersed within the solid soap, and
wherein the emulsion before incorporation into the soap bar comprises 9.4 to 15% of the emulsion water by weight of the soap bar composition.

2. The composition of claim 1 wherein total water in the soap bar composition is 20 to 35% by weight of the soap bar composition.

3. The composition of claim 1 , wherein the emulsion is present in the composition in an amount of at least 5% by weight of the composition.

4. The composition of claim 1 , wherein the emulsion water is present in the emulsion in an amount of from 95% to 98% by weight of the emulsion.

5. The composition of claim 4 , wherein the oil is present in the emulsion in an amount of from 1% to 3% by weight of the emulsion.

6. The composition of claim 1 , wherein the one or more surfactants has an HLB of less than 13.

7. The composition of claim 1 , wherein the one or more surfactants are present in a total amount in the range of 1% to 6% by weight of the emulsion.

8. The composition of claim 1 , wherein the oil is PPG-15 stearyl ether.

9. The composition of claim 1 , wherein the one or more surfactants is selected from the group consisting of: steareth-2, steareth-20, and mixtures thereof.

10. The composition of claim 1 , wherein the solid soap comprises a salt of lauric acid, a salt of coconut oil, palm kernel oil, palm stearin fatty acid, and/or a salt of tallow.

11. The composition of claim 10 , wherein the salt of lauric acid is present in an amount of about 5% and the salt of tallow is present in an amount of 95% by weight of the soap.

12. The composition of claim 1 , wherein the emulsion consists of the oil, the one or more surfactants, the emulsion water, and an antimicrobial agent.

13. The composition of claim 1 , wherein the emulsion consists of the oil, the one or more surfactants, the emulsion water, and a fragrance.

14. The composition of claim 1 , wherein the emulsion consists of the oil, the one or more surfactants, the emulsion water, an antimicrobial agent, and a fragrance.

15. The composition of claim 1 , wherein the emulsion consists essentially of the oil, the one or more surfactants, the emulsion water, and a functional ingredient, wherein the functional ingredient is an antimicrobial agent or a fragrance.

16. The composition of claim 1 , wherein the ratio of the oil to the one or more surfactants is from 0.4:1 to 0.67:1.

17. The composition of claim 1 , wherein the ratio of the oil to the one or more surfactants is from 0.5:1 to 0.67:1.

18. The composition of claim 1 , wherein the ratio of the oil to the one or more surfactants is about 0.43:1.
