Kusukela ngo-1986, abacwaningi baseShayina baye bafunda ukuphepha kwe-marigold extract for eyes; ukuhlolwa kuqinisekisile ukuthi i-marigold root extract iqukethe izinhlanganisela eziningi ze-thiophene, ezingabangela ukucasuka esikhumbeni somuntu, ukwakha amabhamuza, futhi zisongele impilo!
Ngo-2005, i-European Commission for Consumer Products Science, i-SCCP, ikholelwa ukuthi i-marigold lutein namafutha abalulekile ayi-phototoxic. Njengoba kungekho sisekelo somthamo ophephile, kunconywa ukuthi izitshalo zezitshalo ze-marigold namafutha abalulekile akufanele kusetshenziswe izimonyo. Kuze kube ngu-2013, i-International Association of Flavour and Fragrances ibuyekeze idosi lemininingwane lezinto ezinjalo, elinqume ukugcwala okuphezulu okuvumelekile kwe-marigold extract lutein namafutha abalulekile azosetshenziswa kuzimonyo zokuhlala njengo-0.01%.
Ngakho-ke, ngo-2015, i-European Union SCCS{1}}yaphinda{1}yahlola okukhishwe kanye namafutha abalulekile ezitshalo ze-marigold. Lokhu kuhlola okwe-phototoxicity kuphela.
I-European Union SCCS ikholelwa ukuthi: i-marigold ne-madenhair extracts kanye namafutha abalulekile aphephile uma ukugxila okuphezulu okuvunyelwe kungu-0.01% kuzimonyo zokuhlala (ngaphandle kwemikhiqizo yokuvikela ilanga), kodwa -i-trithiophene equkethwe kuzo akumele idlule u-0.35%.
I-marigold ne-madenhair extracts kanye namafutha abalulekile angeke asetshenziswe emikhiqizweni yokuvikela ilanga. Ngoba ngaphansi kwemisebe ye-ultraviolet, i-phototoxicity izokhula!
Ngo-2016, i-SCCS yaveza ukuthi ukugxiliswa okuphezulu okuvunyelwe kwe-marigold encane, i-maidenhair extract namafutha e-rinse{1}}ku-cosmetics kufanele kumiswe ku-0.1%.
Ngo-2018, i-European Union yahlukanisa ngokusemthethweni i-marigold njengesithako esivinjelwe kwezimonyo! I-European Union Gazette imemezele isichibiyelo se-European Commission No{1}}/978, esibuyekeze ngokusemthethweni i-Annexes II kanye ne-III yemithetho yezimonyo ye-EU, okuhlanganisa i-marigold petal extract namafutha ezimbali ohlwini lwezinto ezinqatshelwe, kanye nezindikimba ezincane ze-marigold nezimbali ze-maidenhair namafutha ezimbali. Uhlu lwezinto ezisetshenzisiwe.
Nakuba singekho isimo se-photosensitivity dermatitis esibangelwa i-marigold flower extract/oil, ucwaningo lwe-EU lukholelwa ukuthi -i-tertthiophene iyi-phototoxic kubantu.
Ukwenqatshelwa kwezinto ezingavuthiwe ezifanele ezweni lakithi kungaqeda izingozi zokuphepha ngakolunye uhlangothi, kanti ngakolunye uhlangothi, kungaba semgudwini ofanayo namazinga angaphandle, okubaluleke kakhulu-! Kungani kungavinjelwe ekudleni? Ngenxa yokuthi umkhawulo we-lutein ekudleni Ungaphansi noma ulingana no-12mg/ngosuku, isithako esiyinhloko sesivele siphansi kakhulu, futhi -i-tertthiophene iphephile uma ilandisa Ngaphansi noma ilingana no-0.35% wezingxenye zayo. Kuphephile ukusetshenziswa njengokudla. Ngeke kubangele izingozi zokuphepha. Ngaphezu kwalokho, lolu cwaningo luqondiswe ku-phototoxicity ye--tertthiophene, ephinda kabili ubuthi bayo be-phototoxic ngaphansi kokukhanya kwe-ultraviolet futhi enezingozi ezingaba khona zesikhumba, ngakho ukusetshenziswa kwayo kuzimonyo akuvunyelwe.
