L-Ascorbic Acid Stability Predictor

Estimate the shelf life of an aqueous Vitamin C formulation based on stabilizing factors.

FORMULA pH

Contains Ferulic Acid Contains Vitamin E (Tocopherol) Contains Chelator (e.g. Disodium EDTA)

ESTIMATED SHELF LIFE

LAA stability is highly pH dependent. Above pH 3.5, degradation accelerates exponentially. Ferulic acid and EDTA significantly delay oxidation.
