Abstract

A solid or soft solid antiperspirant/deodorant composition comprising at least one antiperspirant or deodorant active, a base component in an amount of from 2% and 15% by weight of the composition, wherein the base component is C8 to C14 fatty acid in free acid form, and a gellant, wherein the gellant comprises less than 50% by weight of the gellant stearyl alcohol. The C8 to C14 fatty acid in free acid form can be lauric acid. The C8 to C14 fatty acid in free acid form provides antibacterial properties to the compositions.

First claim

What is claimed is:

1. A solid or soft solid antiperspirant/deodorant composition comprising at least one antiperspirant or deodorant active, a base component in an amount of from 2% to 6% by weight of the composition, wherein the base component is lauric acid in free acid form, and a gellant, wherein the gellant comprises less than 50% by weight of stearyl alcohol, and wherein the gellant further comprises at least one selected from the group consisting of polyethylene, polymethylene, and palmitic acid.

2. The composition of claim 1 , wherein the lauric acid is present in an amount in the range of from 2% to 5% by weight of the composition.

3. The composition of claim 1 , wherein the pH of the composition is less than 7.5.

4. The composition of claim 1 , wherein the gellant is present in an amount in the range of 12% to 30% by weight of the composition.

5. The composition of claim 1 , wherein the gellant comprises less than 5% by weight of the stearyl alcohol.

6. The composition of claim 1 , further comprising an emollient component, which is one or more emollients selected from the group consisting of: polypropylene glycol-15 butyl ether, alkyl benzoates, cyclomethicone, and mixtures thereof.

7. The composition of claim 6 , wherein the alkyl benzoates are C 12 to C 15 alkyl benzoates, which are present in an amount in the range of 5% to 17% by weight of the composition.

8. The composition of claim 6 , wherein the sum of the amounts of lauric acid and the emollient component is in the range 20% to 30% by weight of the composition.

9. The composition of claim 1 , further comprising at least one plant oil.

10. The composition of claim 9 , wherein the plant oil is present in an amount of 10 to 40% by weight of the composition.

11. The composition of claim 9 , wherein the plant oil comprises at least one hydrogenated plant oil, which is present in an amount of up to 15% by weight of the composition.

12. The composition of claim 1 , which is a solid composition.

13. The composition of claim 1 , wherein the composition is an anhydrous stick.

14. A method comprising applying the composition of claim 1 to the axillary area of a subject.
