Abstract

Provided is a perfuming method including applying a water-based product to a fabric or a human body and drying, the water-based product containing a perfume precursor composed of an ester of at least one perfume selected from maltol, ethyl maltol, vanillin, ethyl vanillin, and raspberry ketone and at least one aliphatic monocarboxylic acid or aliphatic dicarboxylic acid selected from lauric acid, myristic acid, palimitic acid, stearic acid, oleic acid, adipic acid, and sebacic acid; and subsequently bringing the perfume precursor into contact with moisture in the air to perform hydrolysis, thereby releasing a perfume.

First claim

The invention claimed is:

1. A perfuming method, comprising:
applying a water-based product that comprises a perfume precursor to a fabric or a human body;
drying the water-based product; and
subsequently bringing the perfume precursor into contact with moisture in the air to perform hydrolysis, thereby releasing a perfume,
wherein the water-based product comprises a perfume precursor comprising an ester of i) at least one perfume selected from the group consisting of maltol, ethyl maltol, ethyl vanillin, and raspberry ketone, and ii) at least one aliphatic monocarboxylic acid or aliphatic dicarboxylic acid selected from the group consisting of lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid, adipic acid, and sebacic acid.

2. The perfuming method according to claim 1 , wherein the water-based product is at least one selected member from the group consisting of a fabric treating agent, a softener, a cosmetic, a hair cosmetic, and a detergent.

3. The perfuming method according to claim 1 , wherein the water-based product is a softener.

4. The perfuming method according to claim 3 , wherein the softener comprises a softener substrate that is a quaternized ester amine comprising units of a plant fatty acid and a trialkanolamine.

5. The perfuming method according to claim 3 , wherein a content of the perfume precursor in the softener is 0.001% by mass or more and 10% by mass or less.

6. The perfuming method according to claim 3 , wherein a content of the perfume precursor in the softener is 0.01% by mass or more and 5% by mass or less.

7. The perfuming method according to claim 3 , wherein a content of the perfume precursor in the softener is 0.03% by mass or more and 1% by mass or less.

8. The perfuming method according to claim 1 , wherein said perfume is at least one selected from the group consisting of ethyl maltol, vanillin, ethyl vanillin, and raspberry ketone.

9. The perfuming method according to claim 1 , wherein said aliphatic monocarboxylic acid or aliphatic dicarboxylic acid is at least one selected from the group consisting of lauric acid, stearic acid, oleic acid, adipic acid, and sebacic acid.

10. The perfuming method according to claim 1 , wherein:
said perfume is at least one selected from the group consisting of ethyl maltol, vanillin, ethyl vanillin, and raspberry ketone; and
said aliphatic monocarboxylic acid or aliphatic dicarboxylic acid is at least one selected from the group consisting of lauric acid, stearic acid, oleic acid, adipic acid, and sebacic acid.

11. The perfuming method according to claim 1 , wherein said perfume is at least one selected from the group consisting of ethyl maltol, ethyl vanillin, and raspberry ketone.

12. The perfuming method according to claim 1 , wherein said aliphatic monocarboxylic acid or aliphatic dicarboxylic acid is at least one selected from the group consisting of lauric acid, stearic acid, and oleic acid.

13. The perfuming method according to claim 1 , wherein:
said perfume is at least one selected from the group consisting of ethyl maltol, ethyl vanillin, and raspberry ketone; and
said aliphatic monocarboxylic acid or aliphatic dicarboxylic acid is at least one selected from the group consisting of lauric acid, stearic acid, and oleic acid.
