Ọrụ ime ihu na-abawanye na ogologo alkyl yinye na ọ kachasị elu na nso ma ọ bụ karịa CMC na uru dị n'okpuru 1 mN / m. Na mmiri / ịnweta mmanụ, C12-14 APG na-egosi esemokwu dị ala karịa C12-14 alkyl sulfate lnterfacial esemokwu nke n-decane, isopropyl myristate na 2-octyl dodecanol maka alkyl monoglucosides dị ọcha (C8,C10,C12) na njedebe nke mmanụ polyglycyl na-adabere na polyglycosides. kọwara. Enwere ike iji obere yinye alkyl polyglycosides dị ka emulsifiers maka o/w emulsions yana ngwakọta hydrophobic co emulsifiers.

Alkyl polyglycosides dị iche na ethoxylated nonionic surfactants n'ihi na ha anaghị eme mgbanwe mgbanwe oge okpomọkụ sitere na mmanụ-in-water (O / W) na mmanụ-in-water (W / O) emulsions. Kama nke ahụ, ihe ndị dị na hydrophilic / lipophilic nwere ike imeziwanye site na ịgwakọta ya na emulsifier hydrophobic dị ka glycerin glycated (Glyced) mono-laurate (SML) .N'ezie, omume na-adọ na interfacial esemokwu nke alkyl polyglycoside emulsifier usoro dị nnọọ ka ndị nke ot ọdụ abụba mmanya ethoxylates usoro ma ọ bụrụ na mixing ratio nke hydrophilic / lipophilic emulsifier na-abụghị ethoxylated usoro na-eji kama okpomọkụ dị ka isi usoro omume parameter.

Usoro maka dodecane, mmiri, Lauryl Glucoside na Sorbitan Laurate dị ka hydrophobic coemulsifier na-emepụta microemulsions na ụfọdụ ngwakọta nke C12-14 APG na SML nke 4: 6 ruo 6: 4 (Figure 1). Ọdịnaya SML dị elu na-eduga na w/o emulsions ebe ọdịnaya alkyl polyglycoside dị elu na-emepụta emulsions o/w. Mgbanwe nke mkpokọta emulsifier ntinye uche na-arụpụta ihe a na-akpọ "Kahlweit fish" na eserese nke oge ahụ, ahụ nwere microemulsions nke atọ na ọdụ otu microemulsions, dị ka a na-ahụ na emulsifiers ethoxylated dị ka ọrụ nke okpomọkụ.

Ọkachamma, esemokwu n'etiti ihu kacha dị ala (ihe dịka 10^-3mN/m) ka a hụrụ site na iji ngwakọta C12-14 APG/SML.

N'etiti alkyl glycosides nwere microemulsions, ihe kpatara ọrụ interfacial dị elu bụ na hydrophilic alkyl glycosides na nnukwu glucoside-head groups na hydrophobic co-emulsifiers na obere ìgwè na-agwakọta na mmanụ-mmiri interface na ezigbo ratio.
