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

1 . 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, triacetine and mixtures thereof.

2 . The composition of claim 1 , wherein the R 1 and R 4 substituents of the aromatic nitrile from the formula (I) are hydrogen (formula (II))

and wherein R 2 , R 3 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.

3 . The composition of claim 2 , wherein the R 2 and R 3 substituents of the aromatic nitrile represent methyl.

4 . The composition of claim 1 , wherein the aromatic nitriles are selected from the group consisting of 3,4-dimethylbenzonitrile, 4-(2-methylpropyl)benzonitrile, 3-methylbenzonitrile, 2-methoxybenzonitrile, 3,4-dimethoxybenzontrile, 4-methoxybenzonitrile and mixtures thereof.

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

6 . The composition of claim 1 , wherein the fragrance is 3,4-dimethylbenzonitrile and the solvent is triethylcitrate.

7 . The composition of claim 1 , comprising
(a) an aromatic nitrile selected from the group consisting of 3,4-dimethylbenzonitrile 4-(2-methylpropyl)benzonitrile, 3-methylbenzonitrile, 2-methoxybenzonitrile, 3,4-dimethoxybenzonitrile, 4-methoxybenzonitrile and mixtures thereof, and (b) triethyl citrate.

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

10 . The detergent composition of claim 9 , 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.

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

12 . The cosmetic or personal care composition of claim 11 , wherein said cosmetic or personal care product is a skin care, hair care or sun care product.

13 . A method for providing a cinnamon- and/or almond-like smell to a detergent or cosmetic or personal care composition, comprising the steps of:
(i) providing the fragrance composition of claim 1 , and (ii) adding said fragrance composition to the detergent or cosmetic or personal care composition.

14 - 16 . (canceled)

17 . The method of claim 13 , 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.
