Antiperspirant/deodorant compositions
View Patent ↗Disclosed are new and improved antiperspirant/deodorant compositions and methods of reducing perspiration, where the new and improved antiperspirant/deodorant compositions contain a water dispersible organic polymer and can reduce the concentration of active antiperspirant ingredients while maintaining antiperspirant efficacy.
1. An antiperspirant/deodorant composition comprising:
(i) 0.1 wt. % to 20 wt. % of at least one active antiperspirant ingredient; and
(ii) 7 wt. % to 20 wt. % of a water dispersible organic polymer comprising free carboxylic acid group(s),
wherein the water dispersible organic polymer
a) is a 2,5-Furandione polymer with 1,9-decadiene and methoxy ether;
b) has an acid value greater than 200; and
c) is separated from the active antiperspirant ingredient.
2. The antiperspirant/deodorant composition of claim 1 , wherein said water dispersible organic polymer has an acid value greater than about 350.
3. The antiperspirant/deodorant composition of claim 1 , further comprising a second water dispersible organic polymer, wherein said second water dispersible organic polymer comprises a product of a polymerization reaction of acrylic acid, citraconic acid, crotonic acid, maleic acid, methacrylic acid, methylenesuccinic acid, or combinations thereof.
4. The antiperspirant/deodorant composition of claim 1 , wherein said second water dispersible organic polymer comprises latent acid groups.
5. The antiperspirant/deodorant composition of claim 1 , wherein said second water dispersible organic polymer comprises a product of a polymerization reaction of an alkyl vinyl ether, ethylene, isobutylene, propylene, vinyl acetate, or combinations thereof.
6. The antiperspirant/deodorant composition of claim 5 , wherein said alkyl vinyl ether is methyl vinyl ether or ethyl vinyl ether.
7. The antiperspirant/deodorant composition claim 1 , wherein said antiperspirant/deodorant composition is in the form of a stick, gel, lotion, aerosol, fluid, cream, or powder.
8. A method of controlling perspiration and/or malodor of a human, the method comprising applying the antiperspirant/deodorant composition of claim 1 to the skin of a human.
