Verdict

Very low toxicity profile; naturally occurring amino acid; may cause transient paresthesia (tingling) at high oral doses but this is not relevant at typical cosmetic use levels. A naturally occurring beta-amino acid (3-aminopropionic acid); building block for carnosine synthesis; serves as a precursor for more complex peptide-based cosmetic actives; highly water-soluble

US Note

Allowed - also holds GRAS (Generally Recognized As Safe) status for food use; no cosmetic-specific restrictions
