Xa kuziwa kwizithako zezithambiso, ukongezwa kotywala (i-ethanol) kuye kwaba yingqwalasela enkulu yeengxabano kunye nengqalelo.Utywala bunemisebenzi emininzi eyahlukeneyo kunye nokusetyenziswa kwimixube yezithambiso, kwaye siza kujonga ngakumbi ukuba kutheni isisithako esiqhelekileyo kwizithambiso.
Utywala, igama lekhemikhali i-ethanol, sisinyibilikisi esiphilayo.Ezinye iingcali zesikhumba zikholelwa ukuba ukusetyenziswa kotywala ngokufanelekileyo kuyingenelo kwimpilo yolusu, ingakumbi kulusu olunamafutha kunye nolusu oluthanda ukuba namaqhakuva namaqhakuva.Ngaphaya koko, utywala sisithako esibalulekileyo kubaqulunqi bokuvelisa iimveliso.Ukongezwa kotywala kwizinto zokuthambisa kusekelwe ikakhulu kwiimpawu ezine eziphambili zotywala.Ezi mpawu zenza kube nzima ukufumana izinto ezithatha indawo yotywala.
(1) Ukungena: Utywala sisixhasi sokungena kwendalo, esinokunceda ezinye izithako ezisebenzayo zingene ngcono eluswini ukuze zisebenze.Ngokukodwa kwiimveliso ezithile ezinobunkunkqele obuthile, ezinjengokususwa kwe-freckle kunye neemveliso ezimhlophe, iimveliso zokulawula i-oyile, njl., utywala bunokusetyenziswa ukukhuthaza ukufunxwa kwezithako ezisebenzayo.
(2) Impembelelo yokulawula i-oyile: Utywala bunokunyibilikisa i-sebum yobuso kwaye yinto efanelekileyo yokucoca kunye nokususwa kweoli.Kwakhona kunempembelelo ye-astringent, inceda ukucutha iipores.Oku kuluncedo kakhulu kwesikhumba esinamafutha, njengoko kunokulawula ukukhuselwa kweoli kunye nokuthintela ioli ebusweni, kodwa ayifanelekanga ulusu olomileyo nolubucayi.
(3) Isiphumo sokuthambisa: Utywala bunokukhuthaza i-metabolism ye-keratinocytes, ukukhawuleza kwe-detachment ye-keratinocytes, kunye nokunceda ukuhlaziya i-stratum corneum.Esi siphumo sifanelekile kakhulu kwesikhumba esine-stratum corneum eninzi, kodwa ayifanelekanga kwesikhumba esine-stratum corneum encinci.
(4) Isiphumo se-Solubilization: Ezinye izithako ezisebenzayo ze-oyile-enyibilikayo kunzima ukunyibilika ngokuthe ngqo emanzini.Kule meko, umlamli uyafuneka ukunceda ukuwanyibilikisa emanzini.Utywala ngumlamli olungileyo, ongenakunceda kuphela ezi zithako ezisebenzayo zinyibilike emanzini, kodwa ziphinde zigcine ukucaca kwetoner.Ukongezelela, izityalo ezininzi zifuna utywala njenge-solvent extraction, kuba ngaphandle kokusetyenziswa kotywala, izithako ezisebenzayo kwizityalo azikwazi ukukhutshwa.Esi sesinye sezizathu zokuba kutheni izityalo ezininzi zikhupha utywala.
Ingxabano yotywala
Phezu kwayo nje imisebenzi yazo eyahlukahlukeneyo kwizithambiso, ukusetyenziswa kotywala kukwaphakamisa iinkxalabo ezithile.Abanye abathengi banokuxhalaba malunga neemveliso eziqulethe utywala, ezinokomisa ulusu, zicaphukise okanye zibangele ukusabela komzimba.Ke ngoko, izinto zokuthambisa ezinotywala azifanelekanga kubantu abathile abanolusu olubuthathaka okanye abakwalana notywala.
Ukukhetha utywala
Kwimarike yanamhlanje, izithambiso zibonelela ngoluhlu olubanzi lweemveliso ezinobutywala obuhlukeneyo.Ezinye iimveliso zisebenzisa ukuxinana okuphezulu kotywala, ngelixa ezinye zenziwe ngotywala obuphantsi okanye obungenabo ukukhawulelana neemfuno ezahlukeneyo zabathengi kunye neentlobo zolusu.
Ukuqukumbela
Lilonke, utywala busetyenziswa kwizinto zokuthambisa ngenxa yezizathu ezahlukeneyo kunye nemisebenzi.Kubalulekile ukuba abathengi baqonde iziphumo zotywala kwaye baqonde uhlobo lwesikhumba sabo ukuze benze ukhetho olufanelekileyo lwemveliso kubo.Oku kunceda ukuqinisekisa ukuba iimfuno zakho kunye nempilo yolusu zithathelwa ingqalelo xa ukhetha iimveliso ngexesha lobuhle bakho kunye ne-skincare yesiqhelo.
