What Propanediol is & what it does

A plant-derived humectant and solvent, often used as a gentler alternative to propylene glycol. It hydrates, boosts the spread of actives, and gives a light, non-sticky skin feel.

What does Propanediol do?

Propanediol is a humectant and solvent: it draws water into the skin, dissolves other ingredients, and improves a formula's feel. It is often used as a plant-derived alternative to propylene glycol.

Is Propanediol safe?

Yes. It is well tolerated and considered safe, and tends to be gentler than propylene glycol for sensitive skin.

Does Propanediol clog pores?

No. It is a lightweight, water-soluble humectant that is not comedogenic.

Is Propanediol natural?

Usually yes, in origin: most cosmetic propanediol is made by fermenting corn sugar, which is why it is sold as a natural, renewable alternative to petroleum-based propylene glycol. It is nature-derived rather than something scooped straight out of a plant.

Is Propanediol safe to use during pregnancy?

Propanediol has no known pregnancy concern. It is a gentle, plant-derived humectant and solvent that simply helps a formula feel smooth and hydrating.
