Cosmetic emulsion kugadzirira

Iko solubilization yezvidiki zvidiki zvezvikamu zveoiri mukusuka uye maumbirwo e shampoo anoratidza emulsification zvimiro izvo alkyl polyglycosides zvinofanirwa kutarisirwa kuratidza sevasina unionic surfactants. Zvisinei, kunzwisiswa kwakafanira kwemaitiro echikamu muzvikamu zvakasiyana-siyana zvakakosha kuitira kuti uongorore alkyl polyglycosides se emulsifiers ane simba pamwe chete neakakodzera hydrophobic coemulsifiers.Muzhinji, basa remukati realkyl polyglycosides rinotarirwa nehurefu hweketani yekabhoni uye, kusvika pamwero muduku, nehuwandu hwepolymerization (DP). Chiitiko chekubatana chinowedzera nehurefu hwealkyl cheni uye iri pakakwirira padyo kana pamusoro peCMC ine kukosha kuri pasi pe1 mN/m. Pamvura/mamineral oiri interface, C12-14 APG inoratidza kuderera kwepasi tension pane C12-14 alkyl sulfate lnterfacial kusawirirana kwen-decane, isopropyl myristate uye 2-octyl dodecanol yakayerwa yakachena alkyl monoglucosides (C8, C10, C12, C12, C12, C8, C10, C12, C12) yakatsanangurwa. Medium-chain alkyl polyglycosides inogona kushandiswa se emulsifiers ye o/w emulsion pamwe chete nehydrophobic co emulsifiers.

Alkyl polyglycosides inosiyana kubva kune ethoxylated nonionic surfactants pakuti haishandure tembiricha-induced phase kutendeuka kubva kumafuta-mu-mvura (O/W) kuenda kumafuta-mumvura (W/O) emulsions. Pane kudaro, iyo hydrophilic/lipophilic properties inogona kuenzaniswa nekusanganiswa ne hydrophobic-mono- glycateerGMO emulsions sorbitol mono-laurate (SML) .Kutaura zvazviri, maitiro echikamu uye kupindirana kwehutano hwealkyl polyglycoside emulsifier system yakafanana zvikuru neyemazuva ose emafuta ewaini ethoxylates system kana kusanganiswa kwehuwandu hwehydrophilic / lipophilic emulsifier mu-non-ethoxylated system inoshandiswa panzvimbo yetembiricha sechinhu chinokosha chechikamu chemaitiro.

Iyo sisitimu yedodecane, mvura, Lauryl Glucoside uye Sorbitan Laurate se hydrophobic coemulsifier inoumba microemulsions pane imwe musanganiswa reshiyo yeC12-14 APG kune SML ye4: 6 kusvika 6:4 (Mufananidzo 1). Yepamusoro SML zvirimo zvinotungamira kune w/o emulsion nepo yakakwirira alkyl polyglycoside zvirimo zvinoburitsa o/w emulsions. Kusiyana kwehuwandu hwehuwandu hwe emulsifier hunoguma mune inonzi "Kahlweit hove" muchidimbu chechikamu, muviri une matatu-phase microemulsions uye muswe single-phase microemulsions, sezvinoonekwa ne ethoxylated emulsifiers sekushanda kwekushisa.Kunyanya emulsifying kukwanisa kweC12-14 APG / SML system inofananidzwa ne-exylate yedoro musanganiswa. % yemusanganiswa we emulsifier inokwana kuita imwe-phase microemulsion.

Kufanana kwechikamu chekushandura maitiro emhando mbiri dze surfactant haisi kungogumira kuhutano hwechikamu, asiwo inogona kuwanikwa muhutano hwehutachiwana hwe emulsifying. Zvikuru, kuderera kwakaderera kwepakati pechiso (approx. 10^-3mN/m) yakaonekwa uchishandisa C12-14 APG/SML musanganiswa.

Pakati pealkyl glycosides ine microemulsions, chikonzero chekushanda kwepamusoro-soro ndeyekuti hydrophilic alkyl glycosides nemapoka makuru e-glucoside-head uye hydrophobic co-emulsifiers ane mapoka maduku anosanganiswa pa-oiri-mvura interface muchiyero chakanaka. Hydration (uye saizi inoshanda ye hydration head) haina kutsamira pane tembiricha pane iyo ethoxylated nonionic surfactants. Saka, kupindirana kwekubatana kwechiso kunoonekwa chete kune zvishoma zvishoma-zvinotsamira chikamu chemaitiro eiyo isiri-ethoxylated emulsifier musanganiswa.

Izvi zvinopa zvinonakidza zvikumbiro nekuti, kusiyana nemafuta edoro ethoxylates, alkyl glycosides inogona kugadzira tembiricha-yakagadzikana microemulsions. Nekusiyanisa surfactant yemukati, mhando yesurfactant inoshandiswa, uye chiyero chemafuta / mvura, ma microemulsions anogona kugadzirwa ane chaiwo zvimiro, senge pachena, viscosity, gadziriso mhedzisiro, uye furo zvinhu. Co-emulsifier mune yakasanganiswa sisitimu yealkyl ether sulphate uye isiri-ion, iyo yakawedzera microemulsion nzvimbo inocherechedzwa, uye inogona kushandiswa kugadzira concentrate kana yakanaka particle oil-water emulsions.

Ongororo yakaitwa yepseudoternary phase triangles ye multicomponent masisitimu ane alkyl polyglycoside/SLES uye SML ine hydrocarbon (Dioctyl Cyclohexane) uye alkyl polyglycoside/SLES uye GMO ine polar oiri (Dicaprylyl Ether/Octyl Dodecanol),Ivo vanoratidza nharaunda/kusiyana kwenzvimbo/kusiyana-siyana hexagonal phases uye yelamellar nhanho mukutsamira pane kemikari chimiro uye kusanganisa chiyero chezvikamu. Kana zvikamu zvitatu zvezvikamu izvi zvakaiswa pamusoro pemakona matatu ekushanda anoratidza semuenzaniso wekupupa uye viscosity zvimiro zvemisanganiswa inoenderana, zvinopa rubatsiro rwakakosha kumugadziri wekutsvaga chaiwo uye akanyatsogadzirwa mamicroemulsion maumbirwo eeg ekuchenesa kumeso kana refatting furo yekugezera. Semuenzaniso, yakakodzera microemulsion kuumbwa kwe refatting furo mabhati inogona kutorwa kubva pachikamu chetatu.
