Light Stabilizer 2,4-Dihydroxybenzophenone UV Absorber CAS 131-56-6

Light Stabilizer UV Absorber 2,4-Dihydroxybenzophenone CAS 131-56-6 Cosmetic Raw Materials-Sunscreen

Introduction:

UV absorber is a light stabilizer that can absorb the ultraviolet part of sunlight and fluorescent light sources without changing itself. Plastics and other polymer materials produce auto-oxidation reactions under sunlight and fluorescence due to the action of ultraviolet rays, which leads to the degradation and deterioration of polymers, and the deterioration of appearance and mechanical properties. After adding UV absorber, it can selectively absorb this high-energy ultraviolet light, turning it into harmless energy and releasing or consuming it. Due to the different types of polymers, the wavelength of ultraviolet rays that cause them to deteriorate is also different. Different UV absorbers can absorb ultraviolet rays of different wavelengths. When using, the UV absorber should be selected according to the type of polymer.

Uses:

It is mainly used as a light stabilizer for plastics, etc. It can effectively protect organic glass and fabrics and prevent fabrics from deteriorating due to light. It is also used as an intermediate for synthesizing other ultraviolet absorbers.
