Ngaphambi kokuba izithambiso zibekwe emarikeni, kufuneka zihambe ngothotho lweenkqubo zovavanyo olungqongqo ukuqinisekisa umgangatho wazo kunye nokhuseleko.Ukukhusela impilo yabathengi kunye nokuhlangabezana neemfuno zabo, iifektri zezithambiso, iimpawu kunye neearhente zovavanyo lomntu wesithathu ziya kuqhuba izinto ezahlukeneyo zovavanyo, kubandakanya uvavanyo lwe-microbiological, uvavanyo lokuzinza, uvavanyo lokuhambelana nokupakishwa, uvavanyo lweekhemikhali zococeko, ukumiselwa kwexabiso le-pH. , imifuniselo yokhuseleko lwetyhefu, kunye novavanyo lokhuseleko lwabantu kunye nokusebenza kakuhle.
Uvavanyo lweMicrobiological
Uvavanyo lweMicrobiological linyathelo elibalulekileyo eliqhutywa ziifektri zezithambiso.Ibandakanya ukuvavanyelwa iiparamitha ezinje ngokubala kwekholoni iyonke, i-fecal coliforms, iStaphylococcus aureus, iPseudomonas aeruginosa, ukungunda, kunye negwele.Olu vavanyo luvavanya ubukho bokungcoliseka kwebhaktheriya kunye nokungunda, ngaloo ndlela kuqinisekisa ucoceko kunye nokhuseleko lweemveliso.
Uzinzo Testing
Ngokuxhomekeke kwiimeko zokusingqongileyo, iimveliso zokuthambisa zinokungena kwiinguqu ezingakhuselekanga zomgangatho.Ngovavanyo lokuzinza, abavelisi banokuqinisekisa ukuba iimveliso zigcina ukusebenza kwazo ngexesha leshelufu kunye nokusetyenziswa kwabathengi.Oku kwenziwa kwakhona ukuqinisekisa imiba ebonakalayo yemveliso kunye nomgangatho wayo weekhemikhali kunye ne-microbiological.
UVavanyo lokuNhambelana nePackaging
Ukhetho lokupakisha lubaluleke kakhulu.Njengoko izithako ezithile / ukwakheka kunokusabela ngokulula kunye nezinye izinto, oku kunokubeka umngcipheko kubathengi.Ekuvavanyeni ukuhambelana, kuhlolwa ukuba kukho ukuvuza phakathi kokuqulunqwa kwemveliso kunye nokupakishwa, umonakalo wokupakisha ngenxa yokubola, nokuba kukho utshintsho kumsebenzi wemveliso okanye utshintsho kwi-aesthetics yemveliso ngenxa yokunxibelelana nezinto zokupakisha.
Uvavanyo lweMichiza yococeko
Uvavanyo lweekhemikhali zococeko lujolise ekuvavanyeni amanqanaba eekhemikhali ezinobungozi kwizinto zokuthambisa.Iquka ukuchongwa kwezikhombisi ezifana ne-mercury, ilothe, i-arsenic, kunye nomxholo wezinto ezithintelweyo okanye ezithintelweyo njenge-hydroquinone, i-nitrogen mustard, i-thioglycolic acid, ihomoni kunye ne-formaldehyde.Ukongezelela, ezinye iiparameters ezifana nexabiso le-pH ziyalinganiswa.Ngolu vavanyo, iimveliso zinokuthobela imigangatho yokhuseleko kwaye ziphephe ingozi enokubakho kwimpilo yabantu.
Iimvavanyo zeToxicological
Imifuniselo ye-Toxicological idlala indima ebalulekileyo ekuhloleni ubutyhefu obunokubakho kunye nokucaphuka kwezinto zokuthambisa ebantwini.Izithambiso eziqhelekileyo zifuna iimvavanyo ezibukhali zolusu, iimvavanyo ezibukhali zokucaphuka kwamehlo, kunye novavanyo oluphindaphindiweyo lokucaphukisa ulusu.Izinto zokuthambisa ezinenjongo eyodwa, ngaphandle kolu vavanyo zintathu, zikwafuna ukuvavanya ukwazisa ulusu, uvavanyo lwe-phototoxicity, uvavanyo lwe-Ames, kunye novavanyo lwe-in vitro mammalian cell chromosomal aberration.Olu vavanyo luvavanya ngokubanzi ukhuseleko lweemveliso, luqinisekisa ukuba alubangeli ulusu okanye ukucaphuka kwamehlo okanye lubangele ukusabela komzimba.
UVavanyo loKhuseleko loLuntu kunye noLungelo lweZithambiso zeNjongo eyodwa
Uvavanyo lokhuseleko lomntu kunye nokusebenza kakuhle kwezithambiso zenjongo eyodwa kubandakanya iimvavanyo zepetshi, iimvavanyo zokusetyenziswa komntu, ukumiselwa kwexabiso le-SPF, ukumiselwa kwexabiso le-PA, kunye nomlinganiselo wokungangeni kwamanzi.
Ngokubambelela kwezi zinto zovavanyo, iTopfeel izama ukuhambisa izinto zokuthambisa ezisebenzayo nezikhuselekileyo kubathengi kwihlabathi liphela.
