摘要：
Perfume composition comprising (a) at least one aldehyde of odorous substance with at least 6 carbon atoms or one ketone of odorous substance with at least 6 carbon atoms as well as (b) at least one precursor of odorous oxazolidine substance with the odorous substance aldehyde or the odorous substance ketone mentioned in (a), which may release the same odorous substance aldehyde or the same odorous substance ketone, increasing the aldehyde molar ratio of odorous substance and / or substance ketone odorous (a) to the corresponding precursor of oxazolidine odorous substance (b) from 20: 1 to 1:20, preferably from 10: 1 to 1:10, advantageously from 5: 1 to 1: 5 and being treated in the case of precursor of oxazolidine odorous substance of a compound of 1-aza-3,7-dioxabicyclo [3.3.0] octane of general Formula (I), ** Formula ** in which R1, R2, R3, R4 refer, independently from each other, to moieties that in a compound of general formula R1-C (>； = O) -R2 or R3-C (>； = O) -R4 give an aldehyde of odorous substance with at least 6 carbon atoms or a ketone of odorous substance with at least 6 carbon atoms, R5, R6, R7 they refer, independently of each other, to H or to a hydrocarbon moiety that may be acyclic or cyclic, be substituted or unsubstituted, be branched or unbranched as well as be saturated or unsaturated.Composición de perfume que comprende (a) al menos un aldehído de sustancia olorosa con al menos 6 átomos de carbono o una cetona de sustancia olorosa con al menos 6 átomos de carbono así como (b) al menos un precursor de sustancia olorosa de oxazolidina correspondiente con el aldehído de sustancia olorosa o la cetona de sustancia olorosa mencionada en (a), que puede liberar el mismo aldehído de sustancia olorosa o la misma cetona de sustancia olorosa, ascendiendo la relación molar de aldehído de sustancia olorosa y/o cetona de sustancia olorosa (a) al correspondiente precursor de sustancia olorosa de oxazolidina (b) a de 20:1 a 1:20, preferentemente de 10:1
