About
A modified arginine/methionine amino-acid derivative (HCl salt) used as a skin-conditioning agent. Plausibly safe but with very limited independent data.
Ethylargininoate Acetamidomethionamide HCl is a synthetic amino-acid derivative combining an ethyl ester of arginine with an acetamido methionine amide function, supplied as the hydrochloride salt for cosmetic skin-conditioning use. It is a small, water-soluble molecule sold by specialty cosmetic ingredient suppliers; there is no CIR or SCCS opinion and no published GHS classification specific to it. Because it is built on natural amino-acid scaffolds, biological compatibility is plausibly good and irritation potential at use levels is low. The HCl salt may need pH balancing in the finished product. Independent efficacy and long-term safety data are sparse, so the practical risk profile is benign-to-neutral but anchored conservatively.
