Abstract
Deodorant compositions comprising piroctone acid, its nonprimary olamine salts, metal salts and combination thereof; and a perfume which contains high concentrations of aldehydes and/or ketones are disclosed. These deodorants have good cosmetics, have minimized component interactions, and are excellent in the prevention of body malodors.
Claims15
A deodorant composition consisting essentially of:
- (a) from about 0.1% to about 1.0% of an antimicrobial ingredient effective to combat production of malodors by the body, other than the primary olamine salt piroctone acid, selected from the group consisting of piroctone acid, metal salts of piroctone acid, secondary and tertiary olamine salts of piroctone acid, and mixtures thereof;
- and
- (b) from about 0.01% to about 7% of a perfume effective to inhibit development of body odors comprising from about 5% to about 50% of components selected from the group consisting of aldehydes, ketones and mixtures thereof whose ability to inhibit development of body odors is blocked by a negative interaction with primary olamine salts of piroctone acid.
