BergaSom Soy 50 is a soy-based phosphatidylcholine. BergaSom Soy and BergaSom Sun are high-quality lecithin fractions. They are used in the manufacture of liposomes, nanoemulsions, oleogels and formulations that are physiologically related to the skin, for cosmetic and dermatological products. Phosphatcholine (PC) is a natural and fundamental part of all cell membranes. The linoleic acid and choline it contains are substances that the human body cannot synthesize on its own. Lecithins special abilities allow it to be used in many different formulations, as well as for stabilization purposes. In addition to soy-based fractions Berg + Schmidt offers an innovative, highly pure fraction based on sunflower lecithin as well as hydrogenated and non-hydrogenated fractions from both sources.
