Application of silicone oil in sunscreen-cosmetic silicone oil manufacturer

When the human epidermis is stimulated by ultraviolet rays, the oxidase (tyrosinase) in the pigment cells in the basal layer of the epidermis becomes active, oxidizes and polymerizes tyrosine, one of the amino acids, to generate melanin, which is sent to the epidermis to darken the skin. Silicone sunscreens are non-irritating to the skin, are not prone to chemical changes when exposed to heat and light, and are easily adsorbed on the skin. They can prevent pigmentation caused by sun exposure and prevent tanning, and are more effective than ordinary sunscreens. good. For example, sunscreen containing silicone oil will not be washed away by sea bathing and sweating, and it can prevent the harm of ultraviolet rays. It is best to add methyl phenyl silicone oil to the sunscreen. Phenyl has a certain ability to absorb ultraviolet rays, and its sun protection performance is better than that of methyl silicone oil. Linear alkyl silicone oils are also valuable ingredients in the manufacture of sunscreens, improving their lubricity and hydrophobicity.
