They are anionic surfactant, cationic surfactant, amphoteric surfactant, and nonionic surfactant. The cosmetics and skin care products add surfactants for different functions as the following.   

Emulsifier: anionic surfactant, nonionic surfactant
Detergent: anionic surfactant, cationic surfactant, amphoteric surfactant
Blowing agent: anionic surfactant, amphoteric surfactant
Thickening agent: amphoteric surfactant, nonionic surfactant

Without vitamin A, the rete pegs become flattened. Lang erhans cells need vitamin A to function, but if the vitamin A is inactivated by light, then they cannot function properly and recognize cells whose DNA has been damaged. 2.       Antioxidant Deficiencies of vitamin C permit more free radical ...
