4-Methylbenzylidene Camphor ndi mankhwala oteteza dzuwa omwe amateteza ku UVB (290-320 nm) ndi kuyamwa kwambiri.
ku 301nm.Ndi ufa wosungunuka wamafuta womwe umakhala wosakhazikika pang'ono (zimatenga mphindi 65 kutaya 10% ya mphamvu zake zoteteza ndi 345
mphindi kuti mutaya theka), koma zitha kuthandizabe kukhazikika kwa UVA wosakhazikika fyuluta, avobenzone.
4-Methylbenzylidene Camphor ndi yabwino popanga zinthu zoteteza ku dzuwa zosagwira madzi monga zonona, zopopera ndi ndodo.
Malingaliro a kampani Hebei Zhuanglai Chemical Trading Co., Ltd.ndi kampani yamalonda yakunja, yokhazikika pakupanga ndi kupanga Chemical zopangira, pharmaceutical intermediates.It ili ndi fakitale yake, yomwe imadzipezera yokha mpikisano pamsika.
Kwa zaka zambiri, kampani yathu yapambana chithandizo chamakasitomala ambiri ndikudalira chifukwa nthawi zonse imayesetsa kupanga malonda apamwamba ndi mtengo wabwino.Imadzipereka kukhutiritsa makasitomala onse, pobwezera, kasitomala athu akuwonetsa chidaliro chachikulu ndi ulemu kwa kampani yathu.Ngakhale makasitomala ambiri okhulupirika adapambana zaka izi, Hegui amakhala wodzichepetsa nthawi zonse ndipo amayesetsa kuchita bwino pazonse.
Tikuyembekezera kugwirizana nanu ndikukhala ndi ubale wopambana ndi inu.Chonde khalani otsimikiza kuti tidzakukhutiritsani.Ingomasuka kulankhula nane.
