Brief Introduction:

Methylene bis-benzotriazolyl tetramethylbutylphenol has excellent absorption performance in the broad-spectrum UVA field, because it is an insoluble particle, and its uniform dispersion can exert better ultraviolet absorption effect, and the smaller the particle size of the microparticles, the higher the ultraviolet absorption effect, so they are often used in nanometer form.

In addition, the absorbed ultraviolet energy is converted into harmless vibrational energy through proton transfer (tautomerization mechanism) and disappears. Free radicals are not generated in this reaction, and it will not be damaged after repeated absorption of ultraviolet rays as an ultraviolet absorber, the effect is almost . maintained, which is one of the main characteristics of Methylene bis-benzotriazolyl tetramethylbutylphenol.

In addition, the report shows that when Methylene bis-benzotriazolyl tetramethylbutylphenol is used in combination with other UVB absorbers including Isooctyl p-methoxycinnamate(OMC), a synergistic effect of UVB absorbing ability can be obtained, and it can also be used as a booster for other UVB absorbers.
