Abstract

The present invention relates to the use of hexadeca-8,15-dienal or of a substance mixture which comprises this compound as aroma chemical, in particular as fragrance, or formulation auxiliary; and also to processes for its preparation, moreover aroma substance compositions and compositions comprising hexadeca-8,15-dienal.

First claim

The invention claimed is:

1. A method comprising adding hexadeca-8,15-dienal of the formula I

or a mixture which comprises this compound to a composition, wherein the hexadeca-8,15-dienal of the formula I acts as aroma chemical wherein the composition is selected from the group consisting of perfumes, detergents and cleaners, cosmetic compositions, bodycare compositions, hygiene articles, foods, food supplements, air fresheners, fragrances, pharmaceutical compositions and crop protection compositions.

2. The method according to claim 1 wherein the composition is a formulation which comprises at least one aroma chemical.

3. The method according to claim 1 , wherein the composition is a fragrance composition, and the compound of the formula (I) is used for conveying, modifying and/or intensifying a musk scent note in the fragrance composition by admixing a sensorally effective amount of the hexadeca-8,15-dienal of the formula I or the mixture.

4. The method according to claim 1 , where the compound of the formula (I) is used in stereoisomerically pure form or as 8-(E) and 8-(Z) mixture.

5. The method according to claim 1 , where a stereoisomer mixture the hexadeca-8,15-dienal is used in which the weight fraction of 8-(E)-hexadeca-8,15-dienal, based on the total weight of (E) and (Z)-hexadeca-8,15-dienal, is in a range from 1% to less than 100%.

6. A composition comprising hexadeca-8,15-dienal of the formula I

or of a substance mixture which comprises this compound as aroma chemical;
where the composition is selected from the group consisting of perfumes, detergents and cleaners, cosmetic compositions, bodycare compositions, hygiene articles, foods, food supplements, air fresheners, fragrances, pharmaceutical compositions and crop protection compositions.

7. The composition according to claim 6 , comprising the hexadeca-8,15-dienal of formula I in a weight fraction of from 0.01 to 99.9% by weight, based on the total weight of the composition.

8. The method according to claim 1 , where a stereoisomer mixture the hexadeca-8,15-dienal is used in which the weight fraction of 8-(E)-hexadeca-8,15-dienal, based on the total weight of (E) and (Z)-hexadeca-8,15-dienal, is in a range from 25% to 75%.
