About

Polyarginine HCL is a cosmetic ingredient. Exercise caution due to limited available safety data.

Polyarginine is a homopolymer of the essential amino acid L-arginine. Arginine plays important roles in skin physiology including wound healing and nitric oxide production. The polymer form provides enhanced substantivity to skin compared to free arginine. PubChem data (CID 72364) support a favourable safety profile. Amino acid polymers are widely used in cosmetics. No EU Annex restrictions apply to polyarginine.
