HydratesImproves penetrationLightweight feel
A corn-derived humectant and gentle solvent that hydrates, improves how other actives absorb, and feels weightless.
What it is
Propanediol (1,3-propanediol) is a naturally-derived glycol, typically from corn sugar. It is a capable humectant in its own right, but earns its place mainly as a light, skin-friendly carrier that helps dissolve and deliver other actives, a cleaner-feeling alternative to propylene glycol.
How it works
Hydrates and carries
It attracts water while also improving the solubility and skin-penetration of the actives around it, helping the whole formula perform.
Feels light
It delivers a noticeably lighter, less-tacky finish than older glycols, part of why SENSCERA textures feel weightless.
The evidence
Propanediol is well established as a multifunctional humectant and penetration aid with an excellent tolerability and sustainability profile.
Worth knowing
A supporting molecule that quietly improves how everything else in the formula behaves.
