Stability
N-Methyl-D-aspartic acid, a form of this ingredient, demonstrates good water solubility at 50 mg/mL. While aqueous solutions of related D-Aspartic acid are advised for single-day use at pH 7.2, N-Methyl-D-aspartic acid stock solutions offer greater stability, tolerating refrigeration (2-8°C) for several days, or long-term storage at -80°C for 6 months, or -20°C for 1 month.
Safety
Safety Profile
Methyl Aspartic Acid has not undergone a specific review by the Cosmetic Ingredient Review (CIR) Expert Panel. However, the CIR has generally concluded that alpha-amino acids are safe for cosmetic use. The FDA does not pre-approve cosmetic ingredients, and this compound is not listed among restricted or prohibited substances.
