Gwiritsani ntchito:

Benzophenone-4 ndi yosungunuka m'madzi ndipo imalimbikitsidwa chifukwa cha zinthu zambiri zoteteza ku dzuwa. Mayeso asonyeza kuti Benzophenone-4 imalimbitsa kukhuthala kwa ma gels kutengera

Polyacrylic acid (Carbopol, Pemulen) akamakhudzidwa ndi kuwala kwa UV. Kuchuluka kwa 0.1% kumapereka zotsatira zabwino. Imagwiritsidwa ntchito ngati ultra-violet stabilizer mu ubweya, zodzoladzola, mankhwala ophera tizilombo ndi lithographic plate coating. Tiyenera kudziwa kuti izi ndi zoona.

Kuti tBenzophenone-4 sigwirizana ndi mchere wa Mg, makamaka mu emulsions yamafuta amadzi. Benzophenone-4 ili ndi mtundu wachikasu womwe umakhala wamphamvu kwambiri mu alkaline ndipo ungasinthe chifukwa cha mitundu.

Kulongedza ndi Kusunga:

Phukusi: 25KG/BOTANI

Kusungirako: Kokhazikika m'nyumba, kusunga mpweya wabwino komanso kutali ndi madzi ndi kutentha kwambiri.
