Propanediol
PropanediolHydrator
A plant-derived humectant and solvent that draws water into skin and helps dissolve other ingredients — a common, gentler stand-in for propylene glycol.
What it does
Propanediol is a small molecule that pulls water toward the skin surface (humectant) and also dissolves ingredients that don't mix easily into water-based formulas (solvent). Many brands use it as a corn-derived alternative to propylene glycol because it tends to feel lighter and is less commonly associated with irritation. It quietly supports texture and hydration rather than acting as a headline active.
Also known as
1,3-propanediol
