POLYESTER-12
Safety score · 0–100
Fine
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
Polyester-12 is a synthetic film-former used to add wear and water resistance in colour cosmetics. Its large polymer size keeps it on the skin surface, though environmental persistence is a relevant concern.
Function
Skin benefits
- Acts as a film-forming polymer adding wear and water-resistance
- Improves sensory feel and product spreadability
- Large molecular size limits skin penetration
- Helps stabilize pigments in colour cosmetics
Known concerns
- Synthetic polymer with potential environmental persistence concerns
- May contribute to microplastic discussions depending on particle form
- Limited published toxicology specific to Polyester-12
- Possible residual monomers depending on supplier purity
