Octocrylene CAS 6197-30-4 6197-30-4/5466-77-3/56467-43-7/ 73936 -91-1/2725-22-6

Ultraviolet absorbers can convert high-energy ultraviolet light energy into heat energy or release non-destructive longer light waves, thereby protecting substances added with ultraviolet absorbers from ultraviolet damage. Mainly used as a light stabilizer for plastics, rubber, coatings, dyes, etc., to prevent their photodecomposition in long-term exposure to sunlight. Generally require light color, good miscibility, heat resistance and chemical stability, low volatility and so on. When used as food packaging materials, it also needs to be non-toxic and non-migratory. The sensitive wavelength of various substances to ultraviolet Chemicalbook is different, and the range of light waves that various ultraviolet absorbers can absorb is also different, and the appropriate choice can achieve satisfactory light stabilization effect. Ultraviolet absorbers can be divided into the following categories according to their chemical structure: salicylate esters, benzotriazole, substituted, triazines and other classes, commonly used ultraviolet absorbers: ultraviolet absorbers uV-9, ultraviolet absorbers uV-531, ultraviolet absorbers N-35, ultraviolet absorbers -928, ultraviolet absorbers TBS.
