Abstract

Described herein is a process for preparing a stable perfuming composition including a perfume oil, a viscosifying agent including tricyclodecanedimethanol alcohol, and a perfumery carrier including dipropylene glycol.

First claim

The invention claimed is:

1. A process for preparing a perfuming composition comprising the steps of:
(i) Heating a viscosifying agent comprising tricyclodecanedimethanol alcohol at a temperature greater than 90° C.,
(ii) Optionally, cooling down the solution obtained in step (i) at a temperature greater than room temperature, and
(iii) Cooling down the mixture obtained in step (i) or (ii) to room temperature,
wherein a perfumery carrier comprising dipropylene glycol is further added at any stage of the process, and
wherein a perfume oil comprising at least one perfuming ingredient is further added in step (ii) and/or in step (iii).

2. The process according to claim 1 , wherein at least 5% by weight of tricyclodecanedimethanol alcohol based on the total weight of the perfuming composition is added in step (i).

3. The process according to claim 1 , wherein up to 50% by weight of the perfume oil based on the total weight of the perfuming composition is added in step (ii) or in step (iii).

4. The process according to claim 1 , wherein up to 45% by weight of dipropylene glycol based on the total weight of the perfuming composition is added at any stage of the process.

5. The process according to claim 1 , wherein the weight ratio between tricyclodecanedimethanol alcohol and dipropylene glycol in the perfuming composition is from 3:1 to 1:1.

6. The process according to claim 5 , wherein the weight ratio between tricyclodecanedimethanol alcohol and dipropylene glycol is 5:3.

7. The process according to claim 1 , wherein the perfumery carrier further comprises at least one co-solvent chosen from the group consisting of hexylene glycol, glycerol, 1,2-pentanediol, 1,2-hexanediol, D,L-1,2-isopropylidene glycerol, propanediol, butanediol and mixtures thereof at any stage of the process.

8. The process according to claim 7 , wherein the co-solvent is added in an amount between 5 and 30% by weight based on the total weight of the composition.

9. The process according to claim 1 , wherein an aqueous phase is added in step (ii) or in step (iii).

10. A perfuming composition obtainable by the process as defined in claim 1 .

11. A consumer product comprising the perfuming composition as defined in claim 10 .

12. The process according to claim 1 , wherein cooling down the solution obtained in step (i) occurs at a temperature between 30° C. and 80° C.

13. The process according to claim 1 , wherein an aqueous phase is added in step (ii) or in step (iii) in an amount between 0.01 and 1% by weight based on the total weight of the composition.

14. The consumer product according to claim 11 , wherein the consumer product is in the form of a fine fragrance product or an air freshener.
