Zodzikongoletsera emulsion kukonzekera 2 mwa 2

Mafuta osakaniza amakhala ndi dipropyl ether mu chiŵerengero cha 3: 1.The hydrophilic emulsifier ndi 5:3 wosakaniza wa coco-glucoside (C8-14 APG) ndi sodium laureth sulfate (SLES).Kusakaniza kwa anionic surfactant komwe kumakhala thobvu kwambiri ndiko maziko a zoyeretsa zambiri za thupi. The hydrophobic co-emulsifier ndi glyceryl oleate (GMO) .Madzi amadzi amakhalabe osasintha pa 60%.

Kuyambira ndi dongosolo lopanda mafuta komanso co-emulsifier, 40% C8-14 APG/SLES kusakaniza m'madzi kumapanga kristalo wamadzi wa hexagonal.Phala la surfactant ndi lowoneka bwino kwambiri ndipo silingapope pa 25 ℃.

Gawo laling'ono lokha la C8-14 APG / SLES losakaniza limasinthidwa ndi hydrophobic co-surfactant GMO kuti apange gawo losanjikiza ndi kukhuthala kwapakati kwa 23000 mPa · s pa 1s-1.Pochita, izi zikutanthauza kuti mkulu mamasukidwe akayendedwe surfactant phala amakhala pumpable surfactant maganizo.

Ngakhale kuchuluka kwa GMO, gawo la lamellar limakhalabe.Komabe, mamasukidwe akayendedwe ukuwonjezeka kwambiri ndi kufika misinkhu kwa gel osakaniza madzi amene ngakhale pamwamba pa magawo hexagonal.Mu ngodya ya GMO, kusakaniza kwa GMO ndi madzi kumapanga gel olimba kiyubiki.Mafuta akawonjezedwa, madzi opingasa a hexagonal amapangidwa ndi madzi monga gawo lamkati.The hexagonal · madzi krustalo wolemera mu surfactants ndi lamellar madzi krustalo amasiyana kwambiri mmene amachitira ndi kuwonjezera mafuta.Pomwe makristalo amadzimadzi a hexagonal amatha kungotenga mafuta ochepa, gawo la lamellar limafikira pakona yamafuta.Kuthekera kwa lamellar liquid crystal kutenga mafuta kumawonjezeka bwino ndikuwonjezeka kwa GMO.

Ma Microemulsions amangopangidwa m'makina omwe ali ndi zochepa za GMO.Malo omwe ali ndi ma microemulsions otsika kwambiri amachoka pakona ya APG/SLES motsatira njira ya surfactant/mafuta mpaka 14%.microemulsion imakhala ndi 24% surfactants, 4% coemulsifier ndi 12% mafuta, kuyimira mafuta okhala ndi surfactant concentrate ndi mamasukidwe a 1600 mPa·s pa 1 S-1.

Malo a lamellar akutsatiridwa ndi microemulsion yachiwiri.Microemulsion iyi ndi gel yochuluka yamafuta yokhala ndi kukhuthala kwa 20,000 mPa·s pa 1 S.^-1(12 % surfactants, 8% coemulsifier, 20 % mafuta) ndipo ndi oyenera ngati refatting thovu kusamba.Kusakaniza kwa C8-14 APG / SLES kumathandiza ndi kuyeretsa katundu ndi thovu, pamene mafuta osakaniza amakhala ngati chithandizo cha khungu. wosweka panthawi yogwiritsira ntchito.Panthawi yotsuka, microemulsion yokhala ndi zosakaniza zoyenera imasungunuka ndi madzi ambiri, omwe amatulutsa mafuta ndikuchita ngati chowonjezera pakhungu.

Pomaliza, ma alkyl glycosides amatha kuphatikizidwa ndi ma co-emulsifiers oyenera ndi osakaniza amafuta kuti akonze ma microemulsions.Amadziwika ndi kuwonekera, kukhazikika kwa kutentha kwakukulu, kusungika kwakukulu kosungirako komanso kusungunuka kwakukulu.

Makhalidwe a alkyl polyglycosides okhala ndi unyolo wautali wa alkili (C16 mpaka C22) monga o/w emulsifiers amawonekera kwambiri.M'ma emulsion wamba okhala ndi mowa wamafuta kapena glyceryl stearate monga coemulsifier ndi consistence regulator, ma alkyl polyglycosides atalitali amawonetsa kukhazikika bwino kuposa unyolo wapakatikati C12-14 APG wofotokozedwa pamwambapa.Mwaukadaulo, glycosidation wachindunji wa C16-18 wamafuta amafuta amatsogolera ku chisakanizo cha C16-18 alkyl polyglycoside ndi mowa wa cetearyl momwe mowa wa cetearyl sungathe kutayidwa ndi njira zanthawi zonse kupewa kuwonongeka kwa mtundu ndi fungo.Kugwiritsa ntchito mowa wotsalira wa cetearyl monga co-emulsifier, maziko odzipangira okha o/w okhala ndi 20-60% C6/18 alkyl polyglycoside ndi omwe ali oyenera kwambiri popanga zodzikongoletsera zodzikongoletsera ndi mafuta odzola potengera masamba.Viscosity ndiyosavuta kusintha kudzera mu kuchuluka kwa alkyl polyglycoside/cetearyl alcohol compound ndipo kukhazikika kwabwino kumawonedwa, ngakhale pakakhala ma polar emollients, monga triglycerides.
