The Formula
Formulation
Stability
Methyl Tyrosinate HCl is hygroscopic and readily absorbs moisture from the air, necessitating airtight storage for the solid form at refrigerator temperatures (approximately 4°C). The phenolic hydroxyl group on the tyrosine side chain is susceptible to oxidation, which can be initiated by dissolved oxygen and exposure to light. For stock solutions, storage at -80°C for up to 6 months or -20°C for 1 month is recommended, away from moisture.
Safety
Safety Profile
No formal safety assessment by the Cosmetic Ingredient Review (CIR) or Scientific Committee on Consumer Safety (SCCS) has been conducted. While its synonym, L-Tyrosine, methyl ester, hydrochloride, is generally considered to have low toxicity, TCI Chemicals reports hazard statements H315 ('Causes skin irritation') and H319 ('Causes serious eye irritation'). EWG Skin Deep rates the ingredient 'Low' for Cancer, Allergies & Immunotoxicity, and Developmental and Reproductive Toxicity.
