Propylene Glycon ●
TL;DR. This ingredient is mainly used as a humectant, solvent, and carrier that helps dissolve actives, fragrance components, and preservatives. It can also support product feel and help preservative systems perform more consistently.
What does Propylene Glycon do in a cosmetic formula?
This ingredient is mainly used as a humectant, solvent, and carrier that helps dissolve actives, fragrance components, and preservatives. It can also support product feel and help preservative systems perform more consistently.
Is Propylene Glycon clean?
From a clean-beauty perspective, it is widely used and generally well tolerated, but it can cause stinging or irritation for some sensitive or compromised skin. Some clean standards flag it because conventional supply is synthetic and petrochemical-derived rather than because of broad safety concerns at cosmetic use levels.
Is Propylene Glycon sustainable?
This material is commonly made from petrochemical feedstocks, though bio-based versions exist. It is readily biodegradable and not considered highly persistent, so the main sustainability issue is feedstock origin rather than end-of-life behavior.
Is Propylene Glycon COSMOS-approved?
It is generally not accepted for COSMOS-natural or COSMOS-organic certification when made by conventional petrochemical routes. Its Green Chemistry profile is mixed: biodegradability is favorable, but fossil-carbon sourcing and conventional processing reduce alignment.
How does Propylene Glycon work chemically?
The molecule is a small, water-miscible diol with two hydroxyl groups on a three-carbon chain, which explains its solvent and water-binding behavior. It is commonly used around 1% to 10%, is stable across typical cosmetic pH ranges, and often improves solubility and preservation support in water-based formulas.
