Heylene Glycol ●
TL;DR. This ingredient functions mainly as a solvent and coupling agent, helping dissolve preservatives, fragrance components, and actives. It can also add light humectancy, improve spread, and reduce formula tack.
What does Heylene Glycol do in a cosmetic formula?
This ingredient functions mainly as a solvent and coupling agent, helping dissolve preservatives, fragrance components, and actives. It can also add light humectancy, improve spread, and reduce formula tack.
Is Heylene Glycol clean?
From a clean-beauty perspective, this ingredient is a conventional synthetic solvent with a generally low sensitization profile, though it can sting eyes or reactive skin at higher levels. It has less restricted-list friction than formaldehyde-releasing preservatives, certain cyclic silicones, or some UV filters, but stricter natural standards may not accept it.
Is Heylene Glycol sustainable?
This material is commonly made from petrochemical feedstocks, so its sourcing is not strongly renewable. It is expected to biodegrade and has low bioaccumulation potential, which helps its environmental profile compared with more persistent cosmetic solvents.
Is Heylene Glycol COSMOS-approved?
It is generally not permitted as a standard cosmetic ingredient under COSMOS-natural or COSMOS-organic because it is a synthetic petrochemical-derived solvent. Its Green Chemistry fit is mixed, with useful performance at low levels and favorable biodegradation, but weaker alignment on renewable sourcing.
How does Heylene Glycol work chemically?
The molecule is a small, branched aliphatic diol with two hydroxyl groups, giving it water compatibility plus enough organic character to solubilize less polar formula components. It is typically used at low single-digit percentages, is stable across normal cosmetic pH ranges, and often supports preservative systems by improving distribution in the water phase.
