Ethers are the organic compounds possessing a C-O-C system of bonds. If this C-O-C system is part of a ring, the corresponding compound is classified with the Heterocyclics, e.g., Tocopherol. Sorbitan Derivatives are also heterocyclic ethers. Most ethers used in cosmetics are prepared synthetically. Alkoxylated derivatives are ethers, but are herein classed as Alkoxylated Alcohols, Alkoxylated Amides, Alkoxylated Amines, Alkoxylated Carboxylic Acids, and Polymeric Ethers. The esterified polyglyceryl ethers resulting from the dehydration of glycerin are included in the group of Glyceryl Esters.
Ethers are primarily used as solvents or as fragrance or flavor components and in specialty cosmetic applications. |
