newsHa re ithute ka lipakeng tsa 80 (eo hape e tsejoang ka hore ke lipakeng tsa 80 kapa polysorbate 80) le lipakeng tsa 20 (eo hape e tsejoang ka hore ke lipakeng tsa 20) ka litsela tse tharo tse fapaneng.
Ts'ebetso ea lipakeng tsa 80 e ipapisitse le ho fetoloa ha liphala tsa sorbitol monooleate le ethylene oxide. Ts'ebetso ea lipakeng tsa 20: motsoako oa polyethylene glycol le karolo ea polyethylene glycol. Pakeng tsa 80 ke mofuta oa polyol nonionic surfactant, e sebelisoang haholo ke polysorbate. E sebelisoa haholo litokisetsong tse mokelikeli le tse tiileng tse kang O / W emulsifier, solubilizer, wetting agent, dispersant le stabilizer.
2. Mahareng a ts'ebeliso ea 20: bakeng sa condensation ea disc le ethylene oxide, hobane limolek'hule tsa eona li na le lihlopha tse ngata tsa hydrophilic polyoxyethylene, ka hona e na le hydrophilicity e matla, joalo ka sesepa se seng sa ionic. E sebelisoa hangata e le emulsifier ea O / W, e ka sebelisoa hammoho le alkyl sulfate e leshome le metso e 'meli kapa span mofuta oa emulsifier ho ntlafatsa botsitso ba emulsion. E ka sebelisoa e le solubilizer bakeng sa lithethefatsi tse ling. Sebopeho sa lipakeng tsa 80: boleng ba peroxide ea mahareng a 80 ha e fete 10, e leng 'mala o mosehla o mosehla ho isa ho' mala oa lamunu oa lamunu; e nkga hanyane. Tatso e bohloko haholo, ho na le maikutlo a mofuthu. E qhibiliha ka metsing, ethanol, methanol kapa ethyl acetate, empa e qhibiliha ka har'a oli ea diminerale.
