Abstract

Suggested is a composition with stabilized taste and/or odor, comprising (a) at least one acetophenone derivative of formula (I) wherein R 1 stands for hydrogen or methyl, and R 2 stands for hydrogen, hydroxyl or a —OCH 3 group, or a cosmetically pharmaceutically acceptable salt thereof, and (b) at least one mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric polyhydric C 1 -C 18 alkyl alcohols ester.

First claim

What is claimed is:

1. A method for stabilizing the taste and/or odor of mono- or polyunsaturated C8-C22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester in a composition containing the same, comprising the steps of
adding 4-hydroxyacetophenone to said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester, in an amount effective to prevent oxidation and rancidity of said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester,
forming a composition containing both said 4-hydroxyacetophenone and said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester, with said 4-hydroxyacetophenone present in an amount from 0.01 to 5 wt. %, based on the total weight of said composition,
preventing oxidation and rancidity of said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester for at least two months after forming said composition, and
stabilizing said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester for at least two months after forming said composition.

2. The method of claim 1 , wherein the mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 alkyl alcohol ester comprises
(b-1) at least one acyl compound of formula (II)

wherein
R stands for hydrogen atom or an C 1 -C 18 alkyl group, and
X represents a mono- or polyunsaturated C 8 -C 22 acyl group, and/or
(b-2) at least one acylglycerol compound of formula (III)

wherein
X′, X″ and X′″ independently of one another represents a hydrogen atom or a saturated or mono- or polyunsaturated C 8 -C 22 acyl group, with the proviso that X′, X″ and X′″ do not simultaneously represent a hydrogen atom and at least one of X′, X″ and X′″ being an unsaturated acyl group.

3. The method of claim 1 , where the added amount of 4-hydroxyacetophenone is from 0.05 to 2 wt. %, based on the total weight of the composition comprising both said 4-hydroxyacetophenone and said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester.

4. The method of claim 3 , where the added amount of 4-hydroxyacetophenone is from 0.1 to 1 wt. %, based on the total weight of the composition comprising both said 4-hydroxyacetophenone and said mono- or polyunsaturated C 8 -C 22 fatty acid or its monohydric or polyhydric C 1 -C 18 aliphatic alcohol ester.

5. The method of claim 1 , wherein said fatty acid or ester is a blend of oleic, linoleic, palmitic and stearic acids.

6. The method of claim 1 , wherein said fatty acid or ester is a blend of oleic, linoleic, palmitic and palmitoleic acids.

7. The method of claim 1 , wherein said fatty acid or ester is a blend of oleic and linoleic acids.

8. The method of claim 1 , wherein said fatty acid is linoleic acid.
