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. Nekudaro, kunzwisiswa kwakaringana kwemaitiro echikamu mune akawanda masystem system kunodiwa kuti uongorore alkyl polyglycosides seane simba emulsifiers pamwe chete neakakodzera hydrophobic coemulsifiers.Muzhinji, iyo interfacial chiitiko chealkyl polyglycosides inotarwa neiyo kabhoni chain kureba uye, kune zvishoma. mwero, nedhigirii repolymerization (DP). Chiitiko chekubatana chinowedzera nehurefu hwealkyl cheni uye iri pakakwirira padyo kana pamusoro peCMC ine kukosha kuri pasi pe1 mN/m. Pamvura/mineral oil interface, C12-14 APG inoratidza kuderera kwepasi pasi pane C12-14 alkyl sulfate lnterfacial tension yen-decane, isopropyl myristate uye 2-octyl dodecanol yakayerwa yakachena alkyl monoglucosides (C8, C10, C12) uye kuvimba kwavo nekunyungudika kwealkyl polyglycosides muchikamu chemafuta kwakatsanangurwa. 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 haipindi tembiricha-induced phase kutendeuka kubva kumafuta-mumvura (O/W) kuenda kumafuta-mumvura (W/O) emulsions. Pane kudaro, iyo hydrophilic/lipophilic properties inogona. kuva pakati nepakati nekusanganisa nehydrophobic emulsifier senge glycerin mono-oleate (GMO) kana dehydrated sorbitol mono-laurate (SML) .Ichokwadi, maitiro echikamu uye tension yemukati meiyo alkyl polyglycoside emulsifier system yakafanana zvakanyanya neyeyakajairika. mafuta edoro ethoxylates system kana musanganiswa wehuwandu hwehydrophilic / lipophilic emulsifier mune isiri-ethoxylated system inoshandiswa pachinzvimbo chekushisa seyakakosha chikamu chekuita parameter.

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 hwekugadzirisa emulsifier kunoguma mune inonzi "Kahlweit hove" mumufananidzo wechikamu, muviri une matatu-phase microemulsions uye muswe single-phase microemulsions, sezvinoonekwa ne ethoxylated emulsifiers sekushanda kwekushisa.The high emulsifying Kugona kweC12-14 APG/SML musanganiswa kana uchienzaniswa nemafuta edoro ethoxylate system inoratidzwa mukuti kunyangwe gumi muzana yemusanganiswa we emulsifier inokwana kuumba single-phase microemulsion.

Kufanana kwechikamu chekushandura maitiro emhando mbiri dze surfactant haisi kungogumira kune maitiro echikamu, asiwo inogona kuwanikwa muhutano hwehutachiwana hwe emulsifying system.Iyo hydrophilic - lipophilic properties ye emulsifier musanganiswa yakasvika pakuenzana apo Ratio yeC12 -14 APG/SML yakanga iri 4:6, uye tension yeinterfacial yaive yakaderera. 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 yemulticomponent masisitimu ane alkyl polyglycoside/SLES uye SML ine hydrocarbon (Dioctyl Cyclohexane) uye alkyl polyglycoside/SLES uye GMO ine polar oiri (Dicaprylyl Ether/Octyl Dodecanol),Vanoratidza kusiyana uye hukuru. yenzvimbo dzeo/w, w/o kana mamicroemulsions ezvikamu zvine hexagonal uye yezvikamu zvelamellar zvichitsamira pachimiro chemakemikari 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.
