Abstract

The invention relates to specific ketones of formula (I) which act as photolabile pro-fragrances. The invention further relates to detergents or cleaning agents, cosmetic agents and air freshening products including ketones of said type. The invention also relates to a method for lastingly scenting surfaces and a method for lastingly fragrancing rooms using said ketones.

First claim

What is claimed is:

1. A compound of general formula (I)

wherein
R is a substituted hydrocarbon group, which has at least one C═O group or an ester group;
R1 is —COX;
R2 is a linear or branched, substituted or unsubstituted alkyl group having 3 C atoms;
R3, R4, R5, R6 and R7, independently of one another, are hydrogen, a halogen atom, an amino group, —NO2, —NH alkyl, —N(alkyl) 2 , a linear or branched, substituted or unsubstituted alkoxy group having up to 15 C atoms, or a linear or branched, substituted or unsubstituted alkyl group having up to 15 C atoms, a cycloalkyl group, an acyl group, an aryl group, —OH, —COY group, or a quaternary ammonium group of formula (II)

X is H, —R11, —OR11, —NR11R12, —SR11 or halogen;
Y is hydrogen, alkyl, cycloalkyl, aryl, acyl, —OH, —Oalkyl, —NH 2 , NH-alkyl, —N(alkyl) 2 or halogen,
A is a CH 2 group or a CH 2 CH 2 O group with n=1 to 20;
B is oxygen with m=0 or 1, wherein m=0 when A is a CH 2 CH 2 O group;
R8, R9 and R10, independently of one another, are H or a substituted or unsubstituted group including alkyl, cycloalkyl, alkenyl, aryl or acyl groups, and wherein two of the groups R8, R9 and R10 can be interconnected by ring closure; and
R11 and R12, independently of one another, are hydrogen, a linear or branched, substituted or unsubstituted alkyl, aryl, alkylaryl, arylalkyl or alkenyl group, which can all optionally contain heteroatoms, and wherein R13, R14 and R15, independently of one another, are hydrogen, or a linear or branched, substituted or unsubstituted alkyl group.

2. The compound according to claim 1 , wherein R2 is a linear or branched, substituted or unsubstituted alkyl group having up to 6 C atoms.

3. The compound according to claim 1 , wherein R2 is a methyl group.

4. The compound according to claim 1 , wherein R3, R4, R5, R6 and/or R7 denote hydrogen.

5. The compound according to claim 1 , wherein R3, R4, R5, R6 and R7 denote hydrogen.

6. A compound having a formula selected from the group consisting of (IV) to (X):

7. A detergent or cleaning agent, comprising at least one compound of claim 1 .

8. A detergent or cleaning agent according to claim 7 , wherein the compound of claim 1 comprises 0.0001 and 5% by weight of the total agent.

9. A detergent or cleaning agent according to claim 7 , wherein the compound of claim 1 , comprises between 0.01 and 3% by weight of the total agent.

10. The detergent or cleaning agent according to claim 7 , wherein it further comprises
(1) it includes at least one surfactant, selected from the group consisting of anionic, cationic, non-ionic, zwitterionic or amphoteric surfactants, or mixtures thereof; and/or
(2) the detergent or cleaning agent is in solid or liquid form.

11. An air freshening product, comprising at least one compound of claim 1 .

12. An air freshening product according to claim 11 , wherein the compound of claim 1 comprises 0.0001 and 50% by weight of the total product.

13. An air freshening product according to claim 11 , wherein the compound of claim 1 comprises 0.01 and 3% by weight of the total product.

14. A cosmetic agent, comprising at least one compound of claim 1 .

15. A cosmetic agent according to claim 14 , wherein the compound of claim 1 comprises 0.0001 and 5% by weight of the total agent.

16. A cosmetic agent according to claim 14 , wherein the compound of claim 1 comprises 0.01 and 3% by weight of the total agent.
