Propylene glycol is a small synthetic organic compound (diol) used in cosmetics as a humectant, solvent, and skin-conditioning agent. It is produced from propylene oxide (petroleum) but also from bio-based sources.
PG absorbs and retains water in formulations, improves spreadability, and helps carry active ingredients into the skin. It also serves as a preservative booster and co-solvent for water-insoluble actives.
Propylene glycol is safe at typical cosmetic use concentrations (1–15%). The CIR and EU SCCS have both reviewed and affirmed its safety. It can cause contact sensitization and irritant reactions in some individuals, particularly at concentrations above 5% in leave-on products; those with sensitive or compromised skin may react. It is rapidly metabolized if absorbed and is not bioaccumulative. There is no evidence of carcinogenicity or endocrine disruption at cosmetic use levels. Note: this entry covers topical cosmetic use; ingested large doses (antifreeze context) are toxic, which is a separate matter.

Glycerin or butylene glycol for humectant function; 1,3-propanediol (Zemea) as a bio-based, gentler alternative.
Propylene glycol is used in certain non-toxic antifreeze products, but it is not the same compound as ethylene glycol (the toxic antifreeze). PG is safe in cosmetics and food at approved levels.
In some individuals, especially at higher concentrations in leave-on products. People with eczema or contact dermatitis should patch test products with PG.
No. Propylene glycol is globally permitted in cosmetics and food.
