Solubilization nke ntụnyere obere ihe mmanụ dị na nchacha na nhazi ncha ntutu na-egosipụta njirimara emulsification nke alkyl polyglycosides kwesịrị ịtụ anya na ọ ga-egosi dị ka nonionic surfactants. Otú ọ dị, nghọta ziri ezi nke omume nke oge na usoro multicomponent dị mkpa iji nyochaa alkyl polyglycosides dị ka emulsifiers dị ike na-ejikọta ya na hydrophobic coemulsifiers kwesịrị ekwesị. N'ozuzu, ọrụ interfacial nke alkyl polyglycosides na-ekpebi ogologo oge carbon na, na nke dị ntakịrị. oke, site na ogo nke polymerization (DP). 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 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 ndabere ha dabere na solubility nke alkyl polyglycosides na oge mmanụ ka akọwara. 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, hydrophilic / lipophilic Njirimara nwere ike. mee ka ọ dị mma site na ịgwakọta ya na emulsifier hydrophobic dị ka glycerin mono-oleate (GMO) ma ọ bụ sorbitol mono-laurate dehydrated (SML) .N'ezie, omume nke oge na esemokwu interfacial nke alkyl polyglycoside emulsifier usoro dị nnọọ ka nke a na-emekarị.

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. ikike nke ngwakọta C12-14 APG/SML ma e jiri ya tụnyere usoro ethoxylate mmanya na-aba ụba na-egosipụta n'eziokwu na ọbụna 10% nke ngwakọta emulsifier zuru ezu iji mepụta microemulsion otu oge.

Myirịta nke usoro ngbanwe nke usoro nke ụdị surfactant abụọ abụghị nanị na-ejedebe na omume nke usoro, ma enwere ike ịchọta ya na mgbagwoju anya nke usoro emulsifying. The hydrophilic - lipophilic properties of the emulsifier ngwakọta ruru nha nha mgbe Ratio nke C12. -14 APG/SML bụ 4: 6, na mgbagwoju anya nke ihu bụ nke kasị ala. 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.
