Sauniuniga emulsion teuteu

O le solubilization o vaega la'ititi o suau'u fa'atusa i fa'amama ma suamu fa'ata'ita'iga o lo'o fa'aalia ai uiga fa'a-mulsification autu lea e tatau ona fa'aalia e alkyl polyglycosides e le ninionic surfactants. Ae ui i lea, o le malamalama lelei o le vaega o le amio i faiga faʻapipiʻi e manaʻomia ina ia mafai ai ona iloilo alkyl polyglycosides e avea ma emulsifiers mamana faʻatasi ai ma coemulsifiers hydrophobic talafeagai. E fa'atupula'ia galuega fa'afeso'ota'i i le umi o filifili alkyl ma o lo'o i lona maualuga e latalata pe i luga a'e o le CMC ma lona tau i lalo ole 1 mN/m. I le fa'aogaina o le suau'u vai/mineral, o le C12-14 APG o lo'o fa'aalia ai le va'aiga maualalo ifo nai lo le C12-14 alkyl sulfate i le va'aiga o le n-decane, isopropyl myristate ma le 2-octyl dodecanol ua fuaina mo alkyl monoglucosides mama (C8,C10,C12) ma lo latou fa'alagolago i le suau'u alkyl i luga ole vaega ole alkyl. faamatalaina. E mafai ona fa'aogaina alkyl polyglycosides la'ititi lalaga e fai ma fa'amulu mo o/w fa'amulu fa'atasi ma fa'amulu fa'atasi ma hydrophobic.

Alkyl polyglycosides e ese mai le ethoxylated nonionic surfactants aua latou te le oʻo i le vevela-faʻaosoina suiga vaega mai le suauʻu-i-vai (O / W) i le suauu-i-vai (W / O) emulsions. Nai lo lena, o mea hydrophilic / lipophilic e mafai ona faapaleniina e ala i le faʻafefiloi ma se emulsifier hydrophobic e pei ole derbitate glycerinO e pei o le deorbitate glycerinO. mono-laurate (SML) .O le mea moni, o le vaega o le amio ma interfacial tension o le alkyl polyglycoside emulsifier faiga e matua tutusa ma i latou o le gaʻo ava malosi ethoxylates faiga pe afai o le fefiloi fua faatatau o le hydrophilic / lipophilic emulsifier i le faiga e le-ethoxylated e faaaoga nai lo le vevela e avea ma vaega autu o le amio.

Le faiga mo dodecane, vai, Lauryl Glucoside ma Sorbitan Laurate e pei o se hydrophobic coemulsifier faia microemulsions i se fua faatatau fefiloi patino o C12-14 APG i SML o le 4:6 i le 6:4 (Ata 1). O mea e sili atu i le SML e o'o atu ai i le leai o ni emulsion a'o le maualuga o le alkyl polyglycoside i totonu e maua ai le o/w emulsions. O le fesuiaiga o le aofaʻi o le emulsifier e maua ai se mea e taʻua o le "Kahlweit fish" i le ata vaega, o le tino o loʻo i ai le tolu-vaega microemulsions ma le siʻusiʻu tasi-vaega microemulsions, e pei ona matauina i emulsifiers ethoxylated o se galuega o le vevela. e oo lava i le 10 % o le paluga emulsifier ua lava e fausia ai se microemulsion e tasi-vaega.

O le tutusa o vaega inversion mamanu o ituaiga e lua surfactant e le gata i le amio vaega, ae e mafai foi ona maua i totonu o le tension interface o le emulsifying system.The hydrophilic - lipophilic meatotino o le paluga emulsifier ausia equilibrium pe a o le fua faatatau o le C12-14 APG / SML o 4: 6, ma o le faʻalavelave faʻafefe o loʻo i lalo. Fa'ailogaina, ose va'ava'a maualalo maualalo (pe tusa 10^-3mN / m) na matauina i le faʻaaogaina o le C12-14 APG / SML faʻafefiloi.

I totonu o alkyl glycosides o loʻo i ai microemulsions, o le mafuaʻaga o le maualuga o le gaioioiga faʻafesoʻotaʻi o le hydrophilic alkyl glycosides faʻatasi ai ma vaega tetele glucoside-ulu ma hydrophobic co-emulsifiers ma vaega laiti o loʻo faʻafefiloi i le suauʻu-vai faʻatasi i se fua faʻatatau. O le fa'asusu (ma le tele lelei o le ulu fa'asusu) e fa'aitiitia le fa'alagolago i le vevela nai lo le tulaga i mea fa'afefete etoxylated nonionic surfactants. O le mea lea, e va'aia fa'atasi le va'aiga fa'atasi mo na'o le la'ititi la'ititi o le fa'alagolago i le vevela o le fa'afefiloi emulsifier e le-ethoxylated.

O lenei mea e maua ai talosaga manaia aua, e le pei o le ga'o ava malosi ethoxylates, alkyl glycosides e mafai ona fausia ai microemulsions mautu vevela. E ala i le fesuisuiai o mea o loʻo i totonu o le surfactant, le ituaiga o faʻaoga faʻaoga, ma le fua o le suauʻu / vai, microemulsions e mafai ona gaosia ma mea faʻapitoa, e pei o le manino, viscosity, suiga suiga, ma mea faʻafefe. Co-emulsifier i le faiga fefiloi o alkyl eter sulphate ma non-ion, o le vaega microemulsion faalauteleina o loo matauina, ma e mafai ona faaaoga e fausia ai le concentrate po o vaega lelei emulsions suauu-vai.

O se iloiloga ua faia i tafatolu vaega pseudoternary o multicomponent faiga o loo i ai alkyl polyglycoside / SLES ma SML ma se hydrocarbon (Dioctyl Cyclohexane) ma alkyl polyglycoside / SLES ma GMO ma polar suauu (Dicaprylyl Eter / Octyl Dodecanol), latou faʻaalia vaega mo le fesuisuiai ma le lautele o le tele, vaega hexagonal ma mo vaega lamellar e faalagolago i le fausaga o vailaau ma le faafefiloi o vaega. Afai o nei vaega tafatolu o loʻo faʻapipiʻiina i luga o tafatolu faʻatinoga faʻatasi e faʻaalia mo se faʻataʻitaʻiga o amioga faʻafefe ma mea viscosity o paluga tutusa, latou te maua ai se fesoasoani taua mo le faʻapipiʻi i le sailia o faʻavae microemulsion faʻapitoa ma lelei mo faʻataʻitaʻiga faʻamamā mata poʻo taʻele faʻafefe. Mo se faʻataʻitaʻiga, o se microemulsion talafeagai mo taele faʻafefete e mafai ona maua mai le tafatolu vaega.
