Iingcatshulo ezivela kumthi weThanaka oseMzantsi-mpuma weAsia zinokubonelela ngezinye iindlela zendalo zokukhusela ilanga, ngokutsho kophononongo olutsha olucwangcisiweyo oluvela kwizazinzulu zaseJalan Universiti eMalaysia nakwiYunivesithi yaseLancaster e-UK.
Bebhala kwijenali iCosmetics, izazinzulu zithi iziqwenga ezikumthi bezisetyenziswa ngokwesiko ekunyamekeleni ulusu ekulweni nokwaluphala, ekukhuseleni ilanga, nasekunyangeni amaqhakuva kangangeminyaka engaphezu kwama-2,000. “Izithambiso zelanga zendalo ziye zatsala umdla omkhulu njengendawo enokuthi ithathe indawo yeemveliso zokukhusela ilanga ezenziwe ngeekhemikhali zokwenziwa ezifana ne-oxybenzone ezinokubangela imiba yezempilo kunye nomonakalo kwindalo,” babhala abahlalutyi.
IThanaka
I-Thanaka ibhekisa kumthi oqhelekileyo ofumaneka eMzantsi-mpuma Asia kwaye ikwaziwa ngokuba yi-Hesperethusa crenulata (syn. Naringi crenulata) kunye ne-Limonia acidissima L.
Namhlanje, kukho iimpawu ezininzi eMalaysia, eMyanmar, naseThailand ezivelisa iimveliso zeThanaka “zezimonyo”, bacacisa abahlalutyi, kuquka iThanaka Malaysia kunye neBio Essence eMalaysia, uShwe Pyi Nann kunye neTruly Thanaka evela eMyanmar, kunye neSuppaporn kunye neDe Leaf ezivela eThailand.
“IShwe Pyi Nann Co. Ltd. yeyona nkampani iphambili ekuveliseni nasekuthumeleni iThanaka kwamanye amazwe eThailand, eMalaysia, eSingapore nasePhilippines,” bongeze njalo.
“AmaBurma afaka umgubo weThanaka ngqo eluswini lwawo njenge-sunscreen. Nangona kunjalo, amabala atyheli ashiywe esidleleni awamkelwa ngokubanzi ngamanye amazwe ngaphandle kweMyanmar,” bacacisa abahlalutyi. “Ngenxa yoko, ukuze kuzuze abantu abaninzi nge-sunscreen yendalo, iimveliso zokhathalelo lolusu zeThanaka ezifana nesepha, umgubo okhululekileyo, umgubo wesiseko, i-face scrub, i-body lotion kunye ne-face scrub ziyaveliswa.
“Ukuze kuhlangatyezwane neemfuno zabathengi kunye neemarike, iThanaka ikwayilwe njenge-cleanser, i-serum, i-moisturiser, i-cream yonyango lwamabala e-acne kunye ne-tonic up cream. Uninzi lwabavelisi bongeza izithako ezisebenzayo ezifana neevithamini, i-collagen kunye ne-hyaluronic acid ukwandisa isiphumo se-synergic kunye nokubonelela ngonyango kwiimeko ezahlukeneyo zesikhumba.”
I-Thanaka Chemistry kunye nomsebenzi webhayoloji
Olu phononongo luqhubeka luchaza ukuba izicatshulwa zilungisiwe kwaye zachazwa kwiindawo ezahlukeneyo zezityalo, kuquka ixolo lesiqu, amagqabi, kunye neziqhamo, kunye nee-alkaloids, ii-flavonoids, ii-flavanones, ii-tannins, kunye nee-coumarins zezinye zezinto eziphilayo ezichazwe.
“… uninzi lwababhali lusebenzise izinyibilikisi zendalo ezifana ne-hexane, i-chloroform, i-ethyl acetate, i-ethanol kunye ne-methanol,” baphawule. “Ngoko ke, ukusetyenziswa kwezinyibilikisi eziluhlaza (ezifana ne-glycerol) ekukhupheni izithako ezisebenzayo kwindalo kunokuba yindlela elungileyo endaweni yezinyibilikisi zendalo ekukhupheni iimveliso zendalo, ngakumbi, ekuphuhlisweni kweemveliso zokhathalelo lolusu.”
Uncwadi luchaza ukuba izicatshulwa ezahlukeneyo zeThanaka zinokubonelela ngeenzuzo ezahlukeneyo zempilo, kubandakanya iipropati ze-antioxidant, anti-aging, anti-inflammatory, anti-melanogenic kunye ne-anti-microbial.
Abahlalutyi bathi ngokudibanisa isayensi ukuze baphonononge, banethemba lokuba oku kuya “kusebenza njengesalathiso sophuhliso lweemveliso zokhathalelo lolusu ezineThanaka, ingakumbi i-sunscreen.”
