First claim
Opening claim text (preview).
The invention claimed is: 1. A method, wherein the method reduces the peroxide value (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; 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; and c. 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. 2. The method of claim 1 , 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. 3. 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.
