Propenediol ●
TL;DR. This ingredient primarily functions as a humectant and solvent, helping formulas hold water while improving the dissolution of extracts, preservatives, and other water-soluble components.
What does Propenediol do in a cosmetic formula?
This ingredient primarily functions as a humectant and solvent, helping formulas hold water while improving the dissolution of extracts, preservatives, and other water-soluble components.
Is Propenediol clean?
From a clean-beauty perspective, it is generally well-tolerated and has low irritation potential at normal cosmetic use levels. It has little restricted-list friction and is often used as a lighter-feeling alternative to older glycol solvents.
Is Propenediol sustainable?
This material can be made from renewable plant-derived feedstocks through fermentation, although petroleum-derived routes also exist. It is readily biodegradable and does not raise major persistence or bioaccumulation concerns.
Is Propenediol COSMOS-approved?
It is permitted under COSMOS when produced through accepted routes and compliant with the standard’s processing requirements. Its renewable sourcing potential, biodegradability, and broad formulation utility give it strong Green Chemistry alignment.
How does Propenediol work chemically?
The molecule is a small, water-miscible diol with two hydroxyl groups, which explains its humectant behavior and solvent performance in aqueous systems. Typical use levels are often about 1 to 10 percent, and it is broadly stable across common cosmetic pH ranges while also helping support preservative systems.
