Amalungiselelo e-cosmetic emulsion 2 ye-2

Umxube weoli uqukethe i-dipropyl ether kwi-3: 1. I-hydrophilic emulsifier ngumxube we-5: 3 we-coco-glucoside (C8-14 APG) kunye ne-sodium laureth sulfate (SLES) .Lo mxube we-anionic surfactant ogwebu kakhulu sisiseko seendlela ezininzi zokucoca umzimba.I-hydrophobic co-emulsifier yi-glyceryl oleate (GMO) .Umthamo wamanzi uhlala ungatshintshi kwi-60%.

Ukuqala nge-oyile-free kunye ne-co-emulsifier system, i-40% ye-C8-14 APG / SLES umxube emanzini wenza i-crystal ye-hexagonal liquid. Intlama ye-surfactant i-viscous ephezulu kwaye ayikwazi ukumpontshwa kwi-25℃.

Kuphela inxalenye encinci ye-C8-14 APG / SLES umxube utshintshwa kunye ne-hydrophobic co-surfactant GMO ukuvelisa isigaba esine-layer kunye ne-viscosity ephakathi kwe-23000 mPa · kwi-1s-1. Ngokwesiqhelo, oku kuthetha ukuba i-viscosity surfactant paste ephezulu iba yi-pumpable surfactant concentrate.

Ngaphandle kokunyuka komxholo we-GMO, isigaba se-lamellar sihlala sinjalo. Nangona kunjalo, i-viscosity iyanda kakhulu kwaye ifikelela kumanqanaba ejeli yolwelo engaphezulu kwaleyo yesigaba se-hexagonal. Kwikona ye-GMO, umxube we-GMO kunye namanzi wenza i-gel cubic eqinile. Xa ioli yongezwa, ulwelo olune-hexagonal oluguquguqukayo lwenziwa ngamanzi njengesigaba sangaphakathi. Ikristale engama-hexagonal · elulwelo etyebileyo kwizinto ezenziweyo kunye nekristale yolwelo yelamellar yahluka kakhulu kwindlela abasabela ngayo ekongezweni kwe-oyile. Ngelixa ikristale yolwelo ene-hexagonal inokuthatha kuphela imiyinge ye-oyile encinci kakhulu, indawo yesigaba se-lamellar inabela kude ukuya kwikona yeoli. Umthamo we-lamellar liquid crystal ukuthatha ioli inyuka ngokucacileyo ngokunyuka komxholo we-GMO.

I-Microemulsions yenziwe kuphela kwiinkqubo ezinomxholo ophantsi we-GMO. Indawo ye-low-viscosity o/w microemulsions isuka kwikona ye-APG/SLES ecaleni kwe-surfactant/oyile axis ukuya kwi-oil conte ye-14%. i-microemulsion iqukethe i-24% ye-surfactants, i-4% ye-coemulsifier kunye ne-12% yeoli, emele i-oil-containing surfactant concentrate kunye ne-viscosity ye-1600 mPa · kwi-1 S-1.

Indawo ye-lamellar ilandelwa yi-microemulsion yesibini. Le microemulsion yijeli etyebile ngeoyile kunye ne-viscosity ye-20,000 mPa·s ku-1 S.^-1(I-12% ye-surfactants, i-8% ye-coemulsifier, i-20 % yeoli) kwaye ifanelekile njengendawo yokuhlamba i-foam. Umxube we-C8-14 APG / SLES unceda ngokucoca iipropati kunye ne-foam, ngelixa umxube onamafutha usebenza njengesongezelelo sokunakekelwa kwesikhumba.Ukuze ufumane umphumo wokuxuba we-microemulsion, ioli kufuneka ikhutshwe, oko kukuthi, i-microemulsion kufuneka ibe iphukile ngexesha lokusetyenziswa.Ngexesha lenkqubo yokuhlanjululwa, i-microemulsion enezithako ezifanelekileyo ihlanjululwe ngamanzi amaninzi, ekhupha ioli kwaye isebenze njengesongezelelo kwesikhumba.

Ukushwankathela, i-alkyl glycosides inokudibaniswa kunye ne-co-emulsifiers efanelekileyo kunye nemixube yeoli ukulungiselela i-microemulsions. Ibonakaliswa ngokungafihli, ukuzinza kobushushu obuphezulu, ukuzinza okuphezulu kokugcinwa kunye nokunyibilika okuphezulu.

Iimpawu ze-alkyl polyglycosides ezinamatyathanga e-alkyl amade ngokwentelekiso (C16 ukuya ku-C22) njenge-o/w emulsifiers zibonakala ngakumbi. Kwii-emulsions eziqhelekileyo kunye ne-fatty alcohol okanye i-glyceryl stearate njenge-coemulsifier kunye ne-consistency regulator, i-alkyl polyglycosides ye-long-chain ibonisa ukuzinza okungcono kune-medium-chain C12-14 APG echazwe ngasentla. Ngokobuchwephesha, i-glycosidation ethe ngqo ye-C16-18 yotywala obunamafutha ikhokelela kumxube we-C16-18 alkyl polyglycoside kunye ne-cetearyl alcohol apho i-cetearyl alcohol ayinakuchithwa ngokupheleleyo ngeendlela eziqhelekileyo zokuthintela umbala kunye nokubola kwevumba. Ukusebenzisa intsalela yotywala be-cetearyl njenge-co-emulsifier, i-self-emulsifying o/w bases equlethe i-20-60% ye-alkyl polyglycoside yezona zifanelekileyo ekusebenzeni ukwenza ii-cremes zokuthambisa kunye nezinto zokuthambisa ezisekelwe ngokupheleleyo kwimathiriyeli ekrwada yemifuno. I-Viscosity kulula ukuyihlengahlengisa ngesixa se-alkyl polyglycoside/cetearyl alcohol compound kunye nokuzinza okugqwesileyo kubonwa, nakwimeko ye-polar emollients ephezulu, efana ne-triglycerides.
