PNA-22 CARBOXYETHYL FLUORENE

52

Safety score · 0–100

Moderate

Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.

A 16-nucleobase PNA polymer engineered to form a conditioning film on skin, similar in spirit to other PNA carboxyethyl fluorenes. Same default-down logic as the rest of the PNA series — no public safety dossier puts it in orange.
