  • Method for reducing perception of human underarm odor by a pleasant smelling compound
    Patent number: 5538719
    Abstract: It has now been found that cross-adaptation may occur between two structurally-similar compounds with qualitatively different odors. The perceived intensity of a malodor, for example, underarm sweat, may be decreased by cross-adaptation to at least one ester compound structurally similar to a component of such sweat. Such structurally similar compounds may be used in methods for decreasing the perceived intensity of a malodor such as sweat, in products designed to cover the characteristic odor of sweat, and in methods for covering malodor.
