Verdict
Arginine (CAS 74-79-3) is one of the safest, most well-documented cosmetic amino acids. CIR-approved as safe across all product types including eye area and leave-on. FDA GRAS under 21 CFR 172.320, no EU concentration cap, no SCCS restrictions. Typical use range of 0.5-5% is well within the established safety envelope. Monitor pH when used as neutralizer — alkaline at higher concentrations.
US Note
GRAS as direct food additive under 21 CFR 172.320. No specific FDA restrictions on cosmetic use. 505 reported formulations in VCRP — highest among all alpha-amino acids at time of CIR review.
