Caprylyl glycol is a liquid additive often used in cosmetics, personal care products, and pharmaceuticals. It is a type of alcohol derived from caprylic acid, a fatty acid found in coconut oil, palm oil, and some animal fats. Studies have found that caprylyl glycol has some antibacterial properties and can help boost the preservative blend in some leave-on skin care products. The Cosmetic Ingredient Review panel has found caprylyl glycol safe in cosmetics in amounts between 0.00003%–5%. Toxicologic testing did not reveal caprylyl glycol as a skin or eye irritant in amounts commonly used in cosmetics.
Caprylyl glycol is a multifunctional ingredient primarily used as a preservative and stabilizer in cosmetics and personal care products. It is also known to have emollient properties, which helps moisturize and soften the skin. In addition to its preservative and emollient properties, caprylyl glycol also has antimicrobial properties that can help to prevent the growth of bacteria, yeast, and fungi in cosmetic and personal care products. As a result, it is often used as an alternative to other antimicrobial agents, such as parabens, which have been associated with potential health concerns. Caprylyl glycol is generally considered safe for use in cosmetics and personal care products when used as directed. It has been assessed by regulatory bodies such as the US Food and Drug Administration (FDA) and the European Union (EU) and is approved for use in these regions.
Caprylyl Glycol (1,2-octanediol) could be obtained by epoxidation of 1-olefin with performic acid, a reaction product of hydrogen peroxide and formic acid, hydroxylation with water, or transesterification of ester produced by side reaction with methanol.
