Cosmetic emulsion gadziriro 2 ye2

Musanganiswa wemafuta unosanganisira dipropyl ether muchiyero che3: 1. The hydrophilic emulsifier is a 5:3 musanganiswa wecoco-glucoside (C8-14 APG) uye sodium laureth sulfate (SLES).Musanganiswa uyu unopupuma anionic surfactant ndiyo hwaro hwemichina yakawanda yekuchenesa muviri.Iyo hydrophobic co-emulsifier is glyceryl oleate (GMO) Mvura yemvura inoramba isina kuchinja pa60%.

Kutanga neoiri-isina uye co-emulsifier system, iyo 40% C8-14 APG/SLES musanganiswa mumvura inoumba hexagonal liquid crystal. Iyo surfactant paste ine viscous zvakanyanya uye haigone kupomba pa25 ℃.

Chikamu chidiki chete cheC8-14 APG/SLES musanganiswa chinotsiviwa ne hydrophobic co-surfactant GMO kuti ibudise chikamu chakafukidzwa nepakati viscosity ye23000 mPa · s pa1s-1. Mukuita, izvi zvinoreva kuti iyo yakakwira viscosity surfactant paste inova pumpable surfactant concentrate.

Kunyangwe iyo yakawedzera GMO yemukati, iyo lamellar chikamu chinoramba chakasimba. Nekudaro, iyo viscosity inowedzera zvakanyanya uye inosvika mazinga eiyo gel yemvura inotova pamusoro peiyo yechikamu chehexagonal. Mukona yeGMO, musanganiswa weGMO nemvura inoumba yakasimba cubic gel. Kana oiri yawedzerwa, inverse hexagonal liquid inoumbwa nemvura sechikamu chemukati. Iyo hexagonal · liquid crystal yakapfuma mune surfactants uye lamellar liquid crystal inosiyana zvakanyanya mukuita kwavo pakuwedzera kwemafuta. Nepo iyo hexagonal liquid crystal inogona kungotora mashoma mashoma emafuta, iyo lamellar chikamu nzvimbo inotambanukira kure yakananga kukona yemafuta. Kugona kwelamellar liquid crystal kutora mafuta kunowedzera zvakajeka nekuwedzera GMO zvemukati.

Microemulsions inongoumbwa mumasitimu ane yakaderera GMO zvirimo. Nzvimbo ye-low-viscosity o/w microemulsions inotambanukira kubva kuAPG/SLES kona pamwe neiyo surfactant/oiri axis kusvika kuoiri conte ye14%. iyo microemulsion ine 24% surfactants, 4% coemulsifier uye 12% mafuta, inomiririra mafuta-ine surfactant concentrate ine viscosity ye1600 mPa · s pa1 S-1.

Iyo lamellar nzvimbo inoteverwa neyechipiri microemulsion. Iyi microemulsion ijeri rine mafuta ane viscosity ye20,000 mPa·s pa1 S.^-1(12 % surfactants, 8% coemulsifier, 20 % oiri) uye akakodzera se refatting furo bath. Iyo C8-14 APG / SLES musanganiswa inobatsira nekuchenesa zvivakwa uye furo, nepo musanganiswa wemafuta unoshanda sekuwedzera kwekuchengetedza ganda.Kuti uwane kusanganiswa kweiyo microemulsion, mafuta anofanira kuburitswa, ndiko kuti, iyo microemulsion inofanira kunge iri. yakaputsika panguva yekushandiswa.Panguva yekuchenesa, microemulsion ine zvigadzirwa zvakakodzera inonatswa nemvura yakawanda, iyo inobudisa mafuta uye inoita sekuwedzera kune ganda.

Kupfupisa, alkyl glycosides inogona kusanganiswa neyakakodzera co-emulsifiers uye musanganiswa wemafuta kugadzirira microemulsions. Inoratidzwa nekujeka, kugadzikana kwekushisa kwepamusoro, kugadzikana kwekuchengetedza kwepamusoro uye kunyungudika kwakanyanya.

Izvo zvimiro zvealkyl polyglycosides ane alkyl cheni dzakareba (C16 kusvika C22) se o/w emulsifiers zvinotonyanya kutaurwa. Muma emulsions akajairika ane mafuta edoro kana glyceryl stearate se coemulsifier uye consistency regulator, refu-chain alkyl polyglycosides inoratidza kugadzikana kuri nani pane yepakati-cheni C12-14 APG inotsanangurwa pamusoro. Nehunyanzvi, iyo yakananga glycosidation yeC16-18 fatty alcohol inotungamirira kumusanganiswa weC16-18 alkyl polyglycoside uye cetearyl doro kubva iyo cetearyl doro haigoni kubviswa zvachose nemaitiro anowanzoita kuti ruvara uye kunhuhwirira kurege kuparara. Kushandisa yasara cetearyl doro se-co-emulsifier, self-emulsifying o/w mabhesi ane 20-60% C6/18 alkyl polyglycoside ndiwo akanyatsokodzera mukuita mukugadzira macreme ekuzora uye lotions akavakirwa zvachose pamuriwo wemidziyo. Viscosity iri nyore kugadzirisa kuburikidza nehuwandu hwealkyl polyglycoside / cetearyl doro musanganiswa uye kugadzikana kwakanyanya kunoonekwa, kunyangwe mune yakanyanya polar emollients, senge triglycerides.
