Abstract

It has been found that α-campholenenitrile with formula A and γ-campholenenitrile with formula B ##STR1## are excellent for use as fragrances, especially as components of fragrance mixtures for perfuming cosmetics or other consumer goods. The two nitriles can be used individually or in mixture with each other.

Claims

1. A method of enhancing fragrance of substances, said method comprising adding a small but fragrance enhancing effective amount of a campholenenitrile selected from the group of campholenenitriles of the formula (A) and of the formula (B) below:

##STR6## wherein for formula (A) R¹ equals hydrogen, R², R³ and R⁴ equal methyl, and for formula (B) R¹, R² and R³ equal methyl and R⁴ equals hydrogen.

2. The method of claim 1 wherein said campholenenitrile is α

-campholenenitrile.

3. The method of claim 1 wherein said campholenenitrile is γ

-campholenenitrile.

4. The method of claim 1 wherein said campholenenitrile is a mixture of α

-campholenenitrile and γ

-campholenenitrile which has a content of from 0.5% to 99.5% of α

-campholenenitrile and from 99.5% to 0.5% γ

-campholenenitrile.

5. A cosmetic fragrance composition which comprises a fragrance carrier and a small but fragrance enhancing effective amount of a campholenenitrile selected from the group consisting of α

-campholenenitrile and γ

-campholenenitrile or mixtures thereof.
