Humectant mild preservative and solvent for preservative-free claims
1,2-Hexanediol is the ingredient formulators use when the brief says hydration, shelf life and a lighter skin feel at the same time. It hydrates by attracting and retaining moisture without tackiness, acts as a mild preservative or preservative booster that extends shelf life, and works as a solvent that improves texture and emulsion stability. Paired with p-hydroxyacetophenone it is the backbone of many preservative-free claims.
CAS 6920-22-5 Preservatives With Humectant Properties
Humectant, mild preservative and solvent in a single ingredient, which shortens the raw material list and the number of incoming inspections.
It holds moisture in the skin without the tackiness that higher glycerin loads introduce, so serums and lotions stay light.
At around 5 percent it functions as a mild preservative, often paired with p-hydroxyacetophenone for formulations marketed without conventional preservatives.
As a solvent it helps disperse pigment and holds emulsions together in foundations, lipsticks and eyeliners.
