Abstract

The aspects presented herein provide methods and compositions for the reduction of the peroxide value of perfume ingredients, formulated perfumes, formulated body care products, formulated skin care products, formulated homecare products, essential oils, food raw materials, formulated food products, and natural extracts.

Claims

1. A method, wherein the method reduces the POV of a perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material, the method comprising:

a. adding an α

-oxocarboxylic acid to the perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material having a first POV level; and

b. mixing the α

-oxocarboxylic acid into the perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material for a time sufficient to reduce the first POV level to a pre-determined second lower level.

3. The method of claim 1, wherein the perfumery raw material is treated prior to the incorporation into a perfume.

4. The method of claim 1, wherein the perfumery raw material is treated after incorporation into a perfume.

5. The method of claim 1, wherein the food raw material is treated prior to the incorporation into a flavored article.

6. The method of claim 1, wherein the food raw material is incorporated after the incorporation into a flavored article.

7. The method of claim 1, wherein the concentration of the α

-oxocarboxylic acid ranges from 0.001 to 10 weight percent, after the addition to the formulated perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material.

8. The method of claim 1, wherein the α

-oxocarboxylic acid is selected from the group consisting of;

pyruvic acid, 2-oxovaleric acid, phenylglyoxylic acid, 2-oxobutyric acid, 2-oxo-2-furanacetic acid, oxaloacetic acid, α

-ketoglutaric acid, 2-oxopentandioate, indole-3-pyruvic acid, 2-thiopheneglyoxylic acid, trimethylpyruvic acid, 2-oxoadipic acid, 4-hydroxyphenylpyruvic acid, phenylpyruvic acid, 2-oxooctanoic acid, and mixtures thereof.

9. The method of claim 1, wherein the pre-determined second lower level is between 5 and 20 mmol/L.

10. The method of claim 1, wherein the pre-determined second lower level is between 0 and 6 mmol/L.

11. The method of claim 1, further comprising removing the α

-oxocarboxylic acid from the formulated perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material having the pre-determined second lower level.

12. The method of claim 11, wherein the step of removing the α

-oxocarboxylic acid from the formulated perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material comprises a liquid-liquid extraction.

13. The method of claim 1, further comprising treating the formulated perfume, body care product, cosmetic product, homecare product, perfumery raw material, flavored article, or food raw material with a carbonate salt after removing the α

-oxocarboxylic acid to reduce the acidity of the formulated perfume, body care product, perfumery raw material, flavored article, or food raw material.

2. A method, wherein the method reduces, prevents, or ameiorates formulated perfume, body care product, homecare product, cosmetic product, or perfumery raw material-induced skin irritation of a subject in need thereof, the method comprising:

a. adding an α

-oxocarboxylic acid to formulated perfume, body care product, homecare product, cosmetic product, or perfumery raw material having a first POV level; and

b. mixing the α

-oxocarboxylic acid into the formulated perfume, body care product, homecare product, cosmetic product, or perfumery raw material for a time sufficient to reduce the first POV level to a pre-determined second lower level, wherein the pre-determined second lower level is sufficient to reduce, prevent, or ameliorate the formulated perfume, body care product, homecare product, cosmetic product, or perfumery raw material-induced skin irritation of the subject.
