Hexylene Glycol
Hexylene GlycolHydrator
A small glycol used as a solvent and thinning agent, with mild humectant and preservative-supporting properties.
What it does
Hexylene glycol is a small diol used mostly as a solvent and viscosity reducer — it dissolves other ingredients, keeps a formula pourable, and lends a light feel. It also holds a little water (mild humectant) and can support the preservative system. It is a behind-the-scenes texture-and-stability ingredient rather than a skin active.
