I-Avobunzzones70356-09-1 - isithako esibalulekileyo kwicandelo lokukhusela ilanga kunye neendlela zayo zemakethi

Kwiminyaka yakutshanje, ngokuphucula okuqhubekayo kokwaziswa kwelanga ngokukhuselwa kwelanga, imakethi yemveliso yokukhusela ilanga ibonakalisile indlela yokuphuhlisa. Phakathi kwamathako okunyusa ilanga elininzi, i-Avobensone, njenge-arhente ebalulekileyo yekhemikhali, ifumene ingqalelo ebanzi.

I-Avobibhone sisithako esityibilikayo, kwaye amagama orhwebo aquka i-rasel 1789, i-Eussol 517, njl. Ke ngoko, isetyenziswa ngokubanzi kwiimveliso ezininzi ezithi ukhuseleko lwelanga olubanzi olubanzi, olunokukuthintela ngokukuko ukuncipha kwelanga kunye nokunciphisa umngcipheko womhlaza wolusu.

Nangona kunjalo, i-Avobinzone ayikho ngaphandle kwempikiswano. Ukufundwa nguMsebenzi wokutya wase-US kunye noLawulo lweziyobisi (i-FDA) sele ichaze izithako eziqhelekileyo zeScreen efana ne-Avobin-gestion ezinokungena kwigazi, kwaye igazi lokugxininisa inkxalabo yoluntu malunga nokhuseleko lweemveliso zokukhusela ilanga. Okwangoku, i-FDA igxininise ukuba ukuthathela ingqalelo ukuba i-sunscreens iqinisekisiwe ukuba idlale indima ebalulekileyo ekuthinteleni umhlaza we-ultraviolet, kodwa inokuthi ikhuseleke iimveliso ze-tincreen njenge-tioxide ye-tioxi de kunye neTitanium diokside.

Ukongeza, ngexesha lokusetyenziswa kwe-Avobinjine, ingqalelo kufuneka ihlawulwe kufundiso lwayo. Imele ithintelwe ukuba inxibelelane nee-ion zentsimbi ukuthintela ukungqinelana, kwaye kufuneka isetyenziswe ngokomda ocetyiswayo ukuqinisekisa ukhuseleko kunye nokusebenza kwemveliso. Kubathengi, xa ukhetha iimveliso zokukhusela ilanga ezikwi-Avobinjing, kuyacetyiswa ukuqhuba uvavanyo lwendawo encinci kulusu kuqala ukuze uqaphele ukuba ngaba ikhona into engafunekiyo.

Ngokubanzi, indawo ebalulekileyo ye-Avobidone kwicandelo lokukhuselwa kwelanga azinakuhoywa, kodwa uphando olufanelekileyo lophando kunye nokubekwa esweni kwakhona kufuneka kuqinisekiswe ukuba kuqine ukhuseleko lokukhusela ilanga ngokukhuselekileyo nangokuxhathisa umonakalo we-Ultraviolet. Ngexesha lenkqubo yemveliso, amashishini kufuneka kwakhona alawule ngokungqongqo umgangatho, alandele imigangatho efanelekileyo kunye neenkcazo, kwaye akhuthaze uphuhliso olusempilweni lwe-Avobidone kwimarike yokukhusela ilanga.
