Iyini i-Avobenzone Cas 70356-09-1?

Kunezinhlobo eziningi zokumunca i-ultraviolet, phakathi kwazo izimuncagazi ze-phenylketone ultraviolet zisetshenziswa kakhulu futhi zinenani elikhulu locwaningo olusebenzayo. I-Avobenzone iwuhlobo lokumunca i-benzone ultraviolet, futhi ibaluleke kakhulu ekuhlanganiseni okuphilayo okuphakathi.

Isicelo

I-Avobenzone iyisithako se-ultraviolet sokwenziwa, esimunca kahle i-UV-A (>320nm) ye-ultraviolet. Ingavimba i-UVA ku-wavelength egcwele (320-400nm). Kuyisihlungi se-UVA esincibilika kawoyela esibanzi esibanzi. Ingahlinzeka ngakho konke ukuvikeleka kwe-UVA ne-UVB uma kuhlanganiswe nezinye izinto zokuvikela ilanga ze-UVB ukuvimbela umdlavuza wesikhumba obangelwa ukukhanya.
