I-Oxybenzone CAS 131-57-7 I-Ultraviolet Absorber UV-9;I-Benzophenone-3 Ucoceko >99.0% (HPLC)

I-2-Hydroxy-4-Methoxybenzophenone (i-Oxybenzone; i-Ultraviolet Absorber UV-9; i-Benzophenone-3) (i-CAS: i-131-57-7) yi-agent esebenzayo ephezulu ye-UV efunxa imisebe, yi-FDA evunyiweyo yokucoca i-UV kunye ne-absorber, ekwaziyo ngokufanelekileyo ukufunxa imitha ye-UV ye-290-400 nm wavelength, kodwa phantse ayikufumani ukukhanya okubonakalayo, ngokukodwa okusebenzayo kwiimveliso ezikhanyayo ezinombala okhanyayo.Izinzile ekukhanyeni nasekufudumaleni, ayiboli ngaphantsi kwe-200 ℃, esebenzayo kwipeyinti kunye neemveliso ezahlukeneyo zeplastiki, ezisebenza ngokukodwa kwi-polyvinyl chloride, i-polystyrene, i-polyurethane, i-acrylic resin, ifanitshala ekhanyayo ekhanyayo, kunye nezinto zokuthambisa, kunye umthamo we-0.1-0.5%.I-Oxybenzone isetyenziswa njengesithako kwi-sunscreen kunye nezinye izinto zokuthambisa.I-Oxybenzone isetyenziswa kwiiplastiki njenge-absorption ye-ultraviolet kunye ne-stabilizer.Isetyenziswe, kunye nezinye i-benzophenones, kwi-sunscreens, izitshizi zeenwele, kunye nezithambiso kuba zinceda ukukhusela umonakalo onokuthi ubekho ekukhanyeni kwelanga.Kwakhona kufunyenwe, ekugxininiseni ukuya kwi-1%, kwiipolisi ze-nail.I-Oxybenzone ingasetyenziswa njenge-photostabilizer ye-synthetic resins.I-Benzophenones inokuphuma kwipakethe yokutya, kwaye isetyenziswa ngokubanzi njenge-photo-initiators esetyenziselwa ukuqala imichiza eyomisa i-inki ngokukhawuleza.Njengesikhuseli elangeni, sibonelela ngokugqunywa kwe-ultraviolet ebanzi, kubandakanya i-UVB kunye nemitha ye-UVA yamaza amafutshane.Njengommeli we-aphotoprotective, ineprofayili yokufunxa ukusuka kwi-270 ukuya kwi-350 nm kunye nencopho yokufunxa kwi-288 kunye ne-350 nm.Sesinye sezona zihluzo ze-UVA eziphilayo ezisetyenziswa kakhulu kwizikhuseli zelanga namhlanje.Ikwafumaneka nakwipolishi yeenzipho, iziqholo, isipreyi seenwele, nakwizinto zokuthambisa njengephotostabilizer.Njengoko i-agent ye-ultraviolet absorption, ifumaneka kwi-polyester engaxutywanga, i-polyethylene kunye ne-PVC njl. Ukusetyenziswa ngokubanzi: 0.1-0.5% kwizinto ezincinci, i-0.05-0.2% yento eninzi.Luhlobo lwe-absorption ye-ultraviolet ebanzi, enezinga eliphezulu lokufunxa, i-non-toxic, akukho siphumo se-teratogenic, ukuzinza okulungileyo ekukhanyeni kunye nobushushu, inokufunxa i-UV-A kunye ne-UV-B ngaxeshanye.Isetyenziswa kakhulu kwikhrimu ye-sunscreen, i-cream, ubusi, i-emulsion, i-oyile kunye nezinye izithambiso ze-sunscreen, kwaye zinokusetyenziswa njenge-anti-discoloration agent yeemveliso ze-photosensitive kunye ne-discoloration.Isetyenziswa kwiplastiki, ifayibha yemichiza, ipeyinti kunye neemveliso zepetroleum, ngakumbi kwiimveliso ezikhanyayo nezingafihliyo.Ukusetyenziswa kwe-Oxybenzone Ukusetyenziswa kweplastiki, ifayibha yemichiza, ipeyinti kunye neemveliso zepetroleum, zilungele ngakumbi iimveliso ezikhanyayo ezinombala okhanyayo Usetyenziso lwe-Oxybenzone: Isetyenziswa kakhulu kwi-sunscreen creams, i-creams, i-nectars, i-lotions, i-oyile kunye nezinye izithambiso ze-sunscreen, kwaye njenge-anti. -discoloring agent kwiimveliso ezitshintsha umbala ngenxa ye-photosensitivity.
