Stability and Stabilization of Ascorbic Acid
acid (vitamin C) is extensively used in a variety of formulations including creams. It is an ingredient of anti-aging cosmetic products alone or along with alpha-tocopherol (vitamin E). In solutions and creams, ascorbic acid is susceptible to air and light and undergoes oxidative degradation to dehydroascorbic acid and further to inactive products. The degradation is influenced by oxygen, tempe...

متن کاملKINETIC DETERMINATION OF ASCORBIC ACID a WITH SPECTROPHOTOMETRIC DETECTION
A simple and rapid method has been developed for the determination of ascorbic acid in fruit and pharmaceutical products. The method is based on the measurement of the reaction rate between ammonium molybdate and ascorbic acid in acidic media. The reaction was monitored spectrophotometrically at 800 nm by fixed-time and variable-time methods. The calibration graph was linear in the range of...
