Umgomo weiphepha lezimonyo elimunca uwoyelaisekelwe kakhulu ezintweni ezimbili ezibonakalayo: i-adsorption kanye nokungena. .
Okokuqala, isimiso se-adsorption siwukuthi ingaphezulu lephepha elimunca amafutha line-lipophilicity ethile, evumela amafutha ukuba adsorbed ephepheni. I-Adsorption yinto ebonakalayo ebangelwa into edlula endaweni ye-adsorbent. Ingaphezulu le-adsorbent linendawo enkulu ethile kanye nomsebenzi othile wamakhemikhali, futhi lingakhanga izinto ezizungezile. Imicu yephepha elimunca uwoyela ayinalutho njengoqalo, futhi ukuma nendawo engaphezulu ye-lumen kuhlukile. Uma indawo engaphezulu ikhudlwana, inamandla amandla okukhangisa amafutha. Le micu inezakhiwo ze-hydrophobic kanye ne-lipophilic, eyenza iphepha elimunca uwoyela likwazi ukumunca kahle uwoyela ebusweni. .
Okwesibili, isimiso sokungena siwukuthi iiphepha elimunca uwoyelangokuvamile ithatha indlela yokucubungula indawo engaphansi ukuze yenze i-fiber space yayo ifanele, yenze isenzo se-capillary, ukuze iphepha libe nezici zokungena. Isenzo se-capillary sephepha sivumela uwoyela ukuthi asatshalaliswe ngokulinganayo esikhaleni se-fiber sephepha, futhi asakazeke ngaphakathi ngokusebenzisa isenzo se-capillary sephepha elizungezile. .
Kafushane, iphepha le-cosmetic elimunca uwoyela lisusa ngempumelelo uwoyela wobuso oweqile ngokusebenzisa i-adsorption ne-infiltration, igcina isikhumba sisisha futhi sihlanzekile.
