BLUE LIGHT ABSORBER UV 430(LOTSORB UV 430) (CAS:Trade secrets)

Blue light absorber UV 430

Lotsorb UV 430 is a is a UV blocker derived from vanillin,  a renewable natural resource. It has a remarkably  high absorption in the UV-A wavelength region. Therefore, at merely 750 ppm  loading in 1 mm thick PET,  UV 430 can block out all  UV-A light up to 400 nm. In fact,  UV 430 is 5 times more effective in blocking UV-A light at  400 nm than Lotsorb UV 326, a commonly used UV  blocker, which indicates that UV 430 will have a low  impact on the initial color.

The most important property of UV 430 is that it is  basically insoluble in common food ingredients such as  acetic acid, ethanol, cooking oil, and water. Due to this,  UV 430 has passed the EFSA food contact migration test. However, the low solubility of  UV 430 does not affect its high compatibility with most  commodity plastics like PET, PC, PA, PMMA, and PP.  UV 430 has an extraordinary heat stability, which allows it to be used in plastics that are processed at high temperatures, such as PC and PA.
