Abstract

Suggested is a fragrance composition, comprising
(a) at least one a fragrance selected from the group of aromatic nitriles according to formula (I)

wherein R 1 , R2, R 3 , R 4 and R 5 independently of one another represent hydrogen or linear or branched C 1 -C 10 -alkyl, which is optionally substituted with hydroxy or C 1 -C 4 -alkyl or linear or branched C 1 -C 10 -alkoxy, which is optionally substituted with hydroxy or C 1 -C 4 -alkyl, and

(b) at least one a solvent selected from the group consisting of benzylalcohol, benzylbenzoate, diethylphthalate, dipropylene glycol, ethyl alcohol, iso-propyl myristate, triethylcitrate, downol DPM, IsoPar L, triacetine and their mixtures.

First claim

What claimed is:

1. A fragrance composition, consisting of (a) at least one a fragrance selected from the group consisting of 3,4-dimethylbenzonitrile, 4-(2-methyl propyl)benzonitrile, 3-methylbenzonitrile, 2-methoxybenzonitrile, 3,4-dimethoxy-benzonitrile, 4-methoxybenzonitrile and mixtures thereof, and (b) at least one a solvent selected from the group consisting of benzyl alcohol, benzyl benzoate, diethyl phthalate, dipropylene glycol, ethyl alcohol, iso-propyl myristate, triethyl citrate, triacetine and mixtures thereof.

2. The composition of claim 1 , wherein the solvent is triethylcitrate.

3. A detergent composition comprising the fragrance composition of claim 1 .

4. The detergent composition of claim 3 , wherein said detergent is a heavy duty powder detergent, a heavy duty liquid detergent, a light duty powder detergent, a light duty liquid detergent, a fabric softener, a manual dish wash agent or an all-purpose cleaner.

5. A cosmetic or personal care or composition comprising the fragrance composition of claim 1 .

6. The cosmetic or personal care composition of claim 5 , wherein said cosmetic or personal care product is a skin care, hair care or sun care product.

(i) providing the fragrance composition of claim 1 , and
(ii) adding said fragrance composition to the detergent or cosmetic or personal care composition.

8. The method of claim 7 , wherein said fragrance composition is added to the detergent or cosmetic or personal care composition products in a working amount of from about 0.1 to about 5% b.w.—calculated on the final composition.

9. The composition of claim 1 , wherein the aromatic nitrile is 3,4-dimethylbenzonitrile.

10. The composition of claim 1 , wherein the aromatic nitrile is one of 4-(2-methylpropyl)benzonitrile, 3-methylbenzonitrile, 2-methoxybenzonitrile, 3,4-dimethoxybenzontrile, 4-methoxybenzonitrile.

11. The composition of claim 2 , wherein the aromatic nitrile is one of 4-(2-methylpropyl)benzonitrile, 3-methylbenzonitrile, 2-methoxybenzonitrile, 3,4-dimethoxybenzontrile, 4-methoxybenzonitrile.

12. The composition of claim 1 , wherein the weight ratio of (a) to (b) is from about 10:1 to about 1:10.

13. The composition of claim 12 , wherein the weight ratio is from about 5:1 to about 1:5.

14. The composition of claim 13 , wherein the weight ratio is from about 2:1 to about 1:2.

15. A fragrance composition consisting of a fragrance and a solvent, wherein the fragrance is 3,4-dimethylbenzonitrile and the solvent is triethylcitrate.
