The present invention relates to new malodour-counteracting agents of formula (I) or stereoisomers thereof, particularly useful in blocking the olfactory perception of androstenone, Formula (I), wherein R, R, R, R, R, R, Rand X have the same meaning as that defined in the claims. The present invention also relates to consumer products comprising said agents. The present invention also relates to the use of said agents to suppress or attenuate undesirable odour, as well as to methods to suppress or attenuate undesirable odour employing said compounds. 

Compounds reducing malodour perception and the use thereof

A substantially odorless aromatic amine trapping agent is used in a composition including perfume for the purpose of enabling the perfume and trapping agent to react chemically together spontaneously and reversibly to form a reaction product form which the perfume can be released. In the reaction product, the perfume may be protected against degradation, premature evaporation etc., with the perfume being releasable from the reaction product. In contrast to a pro-perfume, the reaction product formed the present invention is not used by being included as such in a mixture of perfumes or perfumed product, but instead the perfume and trapping agent are included in a mixture of perfumes or perfumed product where they react spontaneously in situ to form a transient reaction product for subsequent release of the perfume. The invention also provides a perfume composition including the trapping agent.

Perfumes
