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 multicomponent e manaʻomia ina ia mafai ai ona iloilo alkyl polyglycosides e avea ma emulsifiers mamana faʻatasi ai ma coemulsifiers hydrophobic talafeagai. lautele, e ala i le tikeri o le polymerization (DP). 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 vai/mineral suau'u fa'afeso'ota'i, C12-14 APG o lo'o fa'aalia i lalo ifo o le va'ava'a 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 faalagolago i le solubility o alkyl polyglycosides i le vaega suauu ua 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 suauu-i-vai (O / W) i le suauu-i-vai (W / O) emulsions. Nai lo lena, o mea hydrophilic / lipophilic e mafai ia faapaleniina e ala i le fefiloi ma se emulsifier hydrophobic e pei o le glycerin mono-oleate (GMO) po o le dehydrated sorbitol mono-laurate (SML) . fatty alcohol ethoxylates system pe afai ole fa'afefiloi fua faatatau ole hydrophilic/lipophilic emulsifier i le non-ethoxylated system e fa'aogaina nai lo le vevela e fai ma ta'iala autu o amioga.

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. Fesuia'iga o le aofa'iga o le emulsifier e maua ai se mea e ta'ua o le "Kahlweit fish" i le ata vaega, o le tino o lo'o i ai tolu-vaega microemulsions ma le si'usi'u tasi-vaega microemulsions, e pei ona matauina i emulsifiers ethoxylated o se galuega tauave o le vevela.O le emulsifying maualuga. gafatia o le paluga C12-14 APG/SML pe a faatusatusa i le ga'o ava malosi ethoxylate faiga o loo atagia i le mea moni e oo lava i le 10% o le emulsifier paluga ua lava e fausia ai se microemulsion tasi-vaega.

O le tutusa o le vaega inversion mamanu o ituaiga e lua surfactant e le gata e faatapulaaina 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 oo atu i le paleni ina ua oo i le fua faatatau o le C12. -14 APG/SML o le 4:6, ma o le fa'alavelave fa'afeso'ota'i sa sili ona maualalo. 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 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.

Ua faia se iloiloga o vaega tafatolu pseudoternary o multicomponent system o loʻo i ai alkyl polyglycoside / SLES ma SML ma se hydrocarbon (Dioctyl Cyclohexane) ma alkyl polyglycoside / SLES ma GMO ma suauu polar (Dicaprylyl Ether / Octyl Dodecanol), latou te faʻaalia le fesuisuiai ma le lautele. o vaega mo o/w, w/o po'o microemulsions mo vaega hexagonal ma mo vaega lamellar e fa'alagolago i le fausaga o vaila'au ma le fa'afefiloi 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, e mafai ona maua mai se faʻavae microemulsion talafeagai mo taele faʻafefete faʻafefete mai le tafatolu vaega.
