Aloin is extracted from the leaves of aloe vera. Aloin, also called barbaloin, is a yellow brown (Aloin 10%, 20%, 60%) or light yelow green (Aloin 90%) powder with bitter taste. Aloin powder is easily soluble in organic solvent, and slightly soluble in water. Aloin is produced from fresh aloe leaves through juicing, colloid milling, centrifugal filtration, concentration, enzymolysis and purification. Aloin is mainly used for improving immunity, inhibiting bacteria, protecting liver and skin. Function: 1. With the function of anti-bactericidal and anti-inflammatory, it can accelerate the concrescence of the wounds. 2. Eliminating waste material from the body and promoting the blood circulation. 3.

Ethyl Ascorbic Acid is an excellent skin whitening agent,it inhibits the activity of Tyrosinase by acting on Cu2+ and it prevents the synthesis of melanin.It is an etherfied derivative of ascorbic acid,one of the most stable derivates of ascorbic acid.It’s also showing a very good stability in all kinds of cosmetic formulations. Ethyl Ascorbic Acid penetrates into skin where it is metabolized to ascorbic acid.Due to this process its efficacy is more pronounced than the one of pure ascorbic acid.Non irritating to skin and eyes.

Ethyl Ferulic Acid is a derivate from ferulic acid with antioxidant effect.Ethyl Ferulic Acid protects skin melanocytes from UV-induced oxidative stress and cell damage. Experiments on human melanocytes irradiated with UVB showed that FAEE treatment reduced the generation of ROS, with a net decrease of protein oxidation. Ethyl ferulic acid is a ferulic acid ester derivative. Compared with ferulic acid, it has greatly-enhanced fat solubility and has the functions of anti-free radicals, anti-oxidation, promoting blood microcirculation, bodybuilding and skin protection in cosmetics CAS.
