    摘要: A method of extending the olfactory effect of a fragrance added to a washed item, comprising the addition to the wash of the fragrance, the fragrance comprising at least one compound selected from the group consisting of

    ethyl (Z)-2-acetyl-4-methyltridec-2-enoate;
    ethyl N,S-bis(4-oxo-4-(2,6,6-trimethylcyclohex-3-en-1-yl)butan-2-yl)cysteinate;
    4-(dodecylthio)-4-methylpentan-2-one;
    1-butoxy-3-((1E,4Z)-hepta-1,4-dien-1-yl)benzene; and
    2-ethoxy-4-((1E,4Z)-hepta-1,4-dien-1-yl)phenol.


    A washed item in which the washing utilized at least one of the compounds and which was then stored, for example, in a cupboard, closet or drawer, is found to have retained a substantial proportion of the fragrance, and for a longer time.

    摘要: The conversion of nootkatol to nootkatene in a terpene blend is mitigated or prevented by substantially or completely separating the nootkatols such as a-nootkatol from compounds present in the terpene blend that catalyze the chemical reaction of nootkatol to nootkatene, and/or by at least partially neutralizing the compounds present in the terpene blend that catalyze the chemical reaction of nootkatol to nootkatene. Methods of preparing terpene blends, terpene blends, flavour compositions containing the terpene blends, beverages and foodstuffs containing the flavour compositions, fragrance compositions containing the terpene blends, and fragranced products containing the fragrance composition are also disclosed.
