Uma kukhulunywa ngezithako zezimonyo, ukungezwa kotshwala (i-ethanol) sekugxilwe kuzimpikiswano eziningi nokunaka.Utshwala bunemisebenzi eminingi ehlukene futhi busetshenziswa ekwenziweni kwezimonyo, futhi sizobhekisisa ukuthi kungani buyizithako ezivamile kwezimonyo.
Utshwala, igama lekhemikhali i-ethanol, i-solvent ephilayo.Abanye ochwepheshe besikhumba bakholelwa ukuthi ukusetshenziswa kotshwala ngendlela enengqondo kunenzuzo empilweni yesikhumba, ikakhulukazi esikhumbeni esinamafutha nesikhumba esithambekele ekubeni nezinduna nezinduna.Ngaphezu kwalokho, utshwala buyisithako esibalulekile sabenzi bokwenza imikhiqizo.Ukwengezwa kotshwala ezimonyoni kusekelwe ikakhulukazi ezicini ezine ezinkulu zotshwala.Lezi zakhiwo zenza kube nzima ukuthola ezinye esikhundleni sotshwala.
(1) Ukungena: Utshwala buyisithuthukisi sokungena esingokwemvelo, esingasiza izithako ezithile ezisebenzayo zingene kangcono esikhunjeni ukuze zisebenze.Ikakhulukazi kweminye imikhiqizo esebenza ngendlela ethile, njengokususwa kwamafreckle nemikhiqizo emhlophe, imikhiqizo yokulawula uwoyela, njll., utshwala bungasetshenziswa ukukhuthaza ukumuncwa kwezithako ezisebenzayo.
(2) Umphumela wokulawula uwoyela: Utshwala bungancibilikisa i-sebum yobuso futhi buyisithako esihle sokuhlanza nokususa uwoyela.Iphinde ibe nomphumela we-astringent, osiza ukushwabana kwezimbotshana.Lokhu kuwusizo kakhulu esikhumbeni esinamafutha, njengoba kungalawula ukuthungwa kwamafutha futhi kuvimbele ukugcoba ubuso, kodwa akufanelekile esikhumbeni esomile nesibucayi.
(3) Umphumela othambisayo: Utshwala bungakhuthaza i-metabolism yama-keratinocyte, busheshise ukuqoqwa kwama-keratinocyte, futhi busize ukuvuselela i-stratum corneum.Lo mphumela ufaneleka kakhulu esikhumbeni esine-stratum corneum ejiyile, kodwa asifanele isikhumba esine-stratum corneum ezacile.
(4) Umphumela we-Solubilization: Ezinye izithako ezincibilikayo ezincibilika uwoyela kunzima ukuzincibilikisa ngokuqondile emanzini.Kulokhu, umlamuli uyadingeka ukusiza ukuwancibilikisa emanzini.Utshwala bungumxhumanisi omuhle, ongakwazi ukusiza lezi zithako ezisebenzayo kuphela ukuthi zincibilike emanzini, kodwa futhi zigcine ukubonakala kwe-toner.Ngaphezu kwalokho, izitshalo eziningi zidinga utshwala njenge-solvent yokukhipha, ngoba ngaphandle kokusetshenziswa kotshwala, izithako ezisebenzayo ezitshalweni azikwazi ukukhishwa.Lesi esinye sezizathu zokuthi kungani izitshalo eziningi ezikhishwe ziqukethe utshwala.
Ingxabano yotshwala
Naphezu kwemisebenzi yawo ehlukahlukene ezimonyoni, ukusetshenziswa kotshwala nakho kuphakamisa ukukhathazeka okuthile.Abanye abathengi bangase bakhathazeke ngemikhiqizo equkethe utshwala, engase yomise isikhumba, icasule noma ibangele ukungezwani komzimba.Ngakho-ke, izimonyo ezinotshwala zingase zingafaneleki kwabanye abantu abanesikhumba esibucayi noma abangezwani notshwala.
Ukukhetha utshwala
Emakethe yesimanje, izimonyo zinikeza inhlobonhlobo yemikhiqizo enotshwala obuhlukahlukene.Eminye imikhiqizo isebenzisa uphuzo oludakayo olugxilile, kanti eminye yenziwa ngotshwala obuncane noma obungekho ukuze kuhlangatshezwane nezidingo ezahlukene zabathengi kanye nezinhlobo zesikhumba.
Isiphetho
Sekukonke, utshwala busetshenziswa ezimonyoni ngenxa yezizathu nemisebenzi eyahlukene.Kubalulekile ukuthi abathengi baqonde imiphumela yotshwala futhi baqonde uhlobo lwesikhumba sabo ukuze benze ukukhetha okufanele kwemikhiqizo yabo.Lokhu kusiza ukuqinisekisa ukuthi izidingo zakho nempilo yesikhumba kuyacatshangelwa lapho ukhetha imikhiqizo ngesikhathi sobuhle bakho kanye nenqubo yokunakekelwa kwesikhumba.
