Methylpropanediol
MethylpropanediolHydrator
A lightweight humectant and solvent that hydrates and can help other ingredients absorb, often replacing heavier glycols.
What it does
Methylpropanediol holds water at the skin surface and dissolves ingredients that are hard to work into water-based formulas. It can also improve how well certain actives penetrate, and it feels light and non-tacky. It is a versatile base ingredient rather than a standalone active.
