What Is Caprylyl Glycol?
Caprylyl glycol is a colorless liquid preservative. It is derived from coconut and has a mild odor.
Is Caprylyl Glycol a Silicone?
Caprylyl glycol is not a silicone.
What Does Caprylyl Glycol Do?
Present in thousands of personal care products, you will commonly find caprylyl glycol in skin care, baby products, makeup, hair care, and cleansing products. This ingredient is water soluble.
Is Caprylyl Glycol Safe?
The Cosmetics Ingredient Review has deemed the ingredient safe for use in cosmetics, and Whole Foods has deemed the ingredient acceptable in its body care quality standards.[5,6] In addition, several studies show the ingredient is not a strong skin/eye irritant or sensitizer.[7,8,9,10] At least one study shows it also has antimicrobial characteristics.
How Caprylyl Glycol Is Made
Commercial production of caprylyl glycol typically starts with the synthesis of ethylene glycol, the simplest of the 1,2-glycols. This usually happens via thermal oxidation of ethylene oxide with water. The commercial production of 1,2-glycols (including caprylyl glycol) most commonly occur with either via catalytic oxidation of the corresponding alkene oxide or the reduction of the corresponding 2-hydroxy acid.
