What Is Decylene Glycol?

Decylene glycol is a synthetic glycol that functions as a skin-conditioning agent to soften skin. Glycols also give slip to products (for easier application) and can help enhance the penetration of other ingredients.\n\nThis particular glycol also has properties that can aid a cosmetic’s preservation system. Typical usage levels in skin care range from 0.1–2%, with higher amounts being better at aiding skin penetration of other ingredients. It is also known as 1,2-decanediol.\n\nDecylene glycol is considered safe as used in cosmetics. It is not known to sensitize or irritate skin.
