Lits'ebetsong tsa chefo e bolaeang likokoanyana, tšebeliso e tobileng ea motsoako o sebetsang ke ka seoelo. Metsoako e mengata e kenyelletsa ho tsoaka chefo e bolaeang likokoanyana le li-adjuvant le solvents ho matlafatsa ts'ebetso le ho fokotsa litšenyehelo. Li-surfactants ke li-adjuvant tsa bohlokoa tse eketsang ts'ebetso ea chefo e bolaeang likokoanyana ha li ntse li theola litšenyehelo, haholoholo ka emulsification, foaming/defoaming, hasane le litlamorao tsa ho koloba. Tšebeliso ea tsona e atileng ha ho etsoa metsoako ea chefo e bolaeang likokoanyana e ngotsoe hantle.
Li-surfactants li ntlafatsa tsitsipano ea sefahleho pakeng tsa likarolo tsa emulsion, ho theha uniform le mekhoa e tsitsitseng ea ho hasana. Sebopeho sa bona sa amphiphilic - se kopanyang lihlopha tsa hydrophilic le lipophilic - se nolofalletsa ho khabisoa libakeng tsa metsi a oli. Sena se fokotsa tsitsipano ea sefahleho le ho fokotsa matla a hlokahalang bakeng sa ho thehoa ha emulsion, kahoo ho matlafatsa botsitso.
Ho hasanya metsoako e sebetsang ea chefo e bolaeang likokoanyana ka metsing kaha likaroloana tse nyane li fana ka ts'ebetso e ntlafetseng ha e bapisoa le metsoako e meng. Li-emulsifiers li susumetsa ka ho toba botsitso ba li-emulsion tsa chefo e bolaeang likokoanyana, e leng tsona tse bontšang katleho ea tsona.
Botsitso bo fapana ho ea ka boholo ba marotholi:
● Likaroloana <0.05 μm: E qhibilihisoa ka metsing, e tsitsitseng haholo.
● Likaroloana 0.05–1 μm: Hangata e qhibilihisoa, e batla e tsitsitse.
● Likaroloana 1–10 μm: Sedimentation e sa fellang kapa lipula ha nako e ntse e ea.
● Likarolo> 10 μm: E bonahala e fanyehiloe, e sa tsitsang haholo.
Ha meaho ea chefo e bolaeang likokoanyana e ntse e fetoha, li-organophosphates tse chefo haholo li nkeloa sebaka ke mekhoa e meng e sireletsehileng, e sebetsang hantle le e nang le chefo e tlase. Lik'hemik'hale tsa Heterocyclic-tse kang pyridine, pyrimidine, pyrazole, thiazole le triazole derivatives-hangata li teng e le lintho tse tiileng tse nang le solubility e tlaase ho li-solvents tse tloaelehileng.

China, moeta-pele oa lefats'e oa tlhahiso le tšebeliso ea chefo e bolaeang likokoanyana, e tlalehile lithane tse limilione tse 2.083 tsa tlhahiso ea chefo e bolaeang likokoanyana ka 2018. Ho eketseha ha tlhokomeliso ea tikoloho ho tsamaisitse tlhokahalo ea lihlahisoa tsa boleng bo holimo. Ka lebaka leo, lipatlisiso le ts'ebeliso ea chefo e bolokang tikoloho, e sebetsang hantle haholo e se e tumme. Li-surfactants tsa boleng bo holimo, joalo ka likarolo tsa bohlokoa, li bapala karolo ea bohlokoa ho nts'etsopele ea mahlale a tsitsitseng a chefo e bolaeang likokoanyana.
