1,2-Hexanediol

1,2-Hexanediol is a clear liquid used in cosmetics as a solvent and conditioning ingredient. It is often found in toners, serums and sprays.

What it is

1,2-Hexanediol is a small, water-soluble alcohol-type molecule (a diol). It is not the drying kind of alcohol found in some sprays; it is a different ingredient with a different name on the label.

Why it's used

Formulators use it to help dissolve other ingredients and to give a formula a lighter, less tacky feel.

Good to know

  • It is generally well tolerated, but any ingredient can bother some skin. Patch test new products before first use.
