Isicelo
I-Octocrylene isetyenziswa njengesithako kwi-sunscreen kunye nezinye izithambiso.Iyakwazi ukufunxa i-UVA kunye ne-UVB (i-absorption range 250-360nm, inokuthintela yonke i-UVB kunye nenxalenye ye-UVA), isizukulwana esitsha se-sunscreen agents.
1. I-UV absorber: I-Octocrylene inamandla okufunxa imitha ye-UVA kunye ne-UVB, kwaye inokusetyenziswa kwiimveliso ze-sunscreen ukunceda ukukhusela ulusu kwimitha ye-UV.Inokunciphisa ngokufanelekileyo umonakalo wemitha ye-ultraviolet esikhumbeni kwaye ithintele ukushisa kwelanga, amabala elanga kunye nezinye iingxaki zesikhumba ezinxulumene nemitha ye-ultraviolet.
2. Uzinzo oluphuculweyo: I-Octocrylene inokuphucula ukuzinza kwezinye i-Absorbers ze-UV kunye nokunciphisa izinga lokubola phantsi kokukhanya kwelanga.Oku kuyenza ibe yenye yezithako ezisetyenziswa ngokuqhelekileyo kwizithako zokuthambisa kunye neemveliso zokhathalelo lwelanga.
3. Ubulali: Xa kuthelekiswa nezinye izinto ezifunxayo zeUV, iOctocrylene ithambile kwaye ayinakukwazi ukubangela ukwaliwa nolusu okanye ukucaphuka.Oku kuyenza ilungele zonke iintlobo zolusu, kuquka ulusu olubuthathaka.
