NICOTINAMIDE
Introduction
Niacinamide, also known as nicotinamide, vitamin B3 or vitamin PP, is a water-soluble vitamin and belongs to B vitamins. The niacinamide part in these two coenzyme structures in the human body has the properties of adding Chemicalbook hydrogen and dehydrogenation, which plays a role in biological oxidation. Hydrogen transmission can promote tissue respiration, biological oxidation process and metabolism, which is of great significance for maintaining the integrity of normal tissues, especially the skin, digestive tract and nervous system. When it is deficient, it causes prosthema because the respiration and metabolism of the cells are affected.
Chemical properties
Niacinamide is a white needle-shaped crystal or crystalline powder, odourless or slightly smelly, and slightly bitter. The relative density is 1.4, and the melting point is 129-131℃. 1g of this product is soluble in 1mL of water, 1.5mL of ethanol or 10mL of glycerine, and is insoluble in ether. It is relatively stable. It is resistant to acid, alkali and high temperature. It is stable to light and heat in dry air. When heated in alkaline or acidic solutions, it produces niacin.
Physiological function
Good anti-wrinkle ability The anti-wrinkle ability of niacinamide is that it can activate ChemicalbookATP, provide vitality to keratin cells, increase the synthesis of collagen, and has good synergy, which can be used with other anti-wrinkle ingredients. Many studies at home and abroad have shown that niacinamide can effectively reduce the occurrence of skin light immunosuppression under ultraviolet irradiation.
