Iipropati zokusebenza ze-Alkyl Polyglycosides kwiiMveliso zoNakekelo loMntu

  • Ugxininisa

Ukongezwa kwe-alkyl polyglycosides kuguqula i-rheology ye-concentrated surfactant mixes ukuze i-concentrate empompekayo, engenakulondolozwa kunye ne-dilutable elula equlethe ukuya kuma-60 % yezinto ezisebenzayo zinokulungiswa.

Umxube ogxininisiweyo wezi zithako udla ngokusetyenziswa njengesithako sokuthambisa okanye, ngakumbi, njengogxininiso olungundoqo kwimveliso yezinto zokuthambisa (umzekelo, ishampu, ishampoo yokugxila, ukuhlamba amagwebu, ukuhlamba umzimba, njl. njl.).

Ngaloo ndlela, i-alkyl glucosides isekelwe kwii-anions ezisebenzayo ezifana ne-alkyl ether sulphates (i-sodium okanye i-ammonium), i-Betaines kunye / okanye i-non-ionic surfactants kwaye ngoko ke inobulali ngakumbi kwiso kunye nesikhumba kuneenkqubo zendabuko. Kwangaxeshanye, babonisa ukusebenza okugqwesileyo kogwebu, ukuqina komgangatho kunye nokusebenza kokusebenza. Ugxininiso olukhulu lukhethwa ngenxa yezizathu zoqoqosho kuba kulula ukuphatha kunye nokuhlanjululwa kwaye alunayo i-hydrogen. Umlinganiselo wokuxuba wesiseko se-surfactant ulungelelaniswe kwiimfuno zokusebenza zemiqulu.

  •  Ukucoca umphumo

Ukucoca ukusebenza kwee-surfactants kunokuthelekiswa ngovavanyo olulula. I-epidermis yehagu iphathwe ngomxube we-sebum kunye ne-surfactant yomsi ihlanjwe ngesisombululo se-3% se-surfactant imizuzu emibini. Kuluhlu lwe-microscopic, ixabiso elingwevu lichongwa ngokuhlalutya umfanekiso wedijithali kwaye lifaniswa nesikhumba sehagu esingaphathwanga. Le ndlela ivelisa amanqanaba alandelayo okucoca iimpawu: i-lauryl glucoside ivelisa iziphumo ezilungileyo, ngelixa i-coconut amphoteric acetate ivelisa iziphumo ezimbi kakhulu. I-Betaine, i-sulfosuccinate kunye ne-alkyl ether sulfate eqhelekileyo ikuluhlu oluphakathi kwaye alukwazi ukwahlula ngokucacileyo omnye komnye. Kolu gxininiso luphantsi, kuphela i-lauryl glucoside enesiphumo esinzulu sokucoca i-pore.

  • Iziphumo kwiinwele

Ubumnene be-alkyl glycosides esikhumbeni bukwabonakaliswa ekunyamekelweni kweenwele ezonakalisiweyo.Xa kuthelekiswa nesisombululo esiqhelekileyo se-etheric acid, isisombululo se-alkyl glucoside kwi-perm tensile amandla okunciphisa kuncinci kakhulu. , i-wave proofing and bleaching agents ngenxa yogcino lwazo lwamanzi olugqwesileyo kunye nokuzinza kwealkali.Uphononongo kwifomula yamaza engaguqukiyo ibonisa ukuba ukongezwa kwe-alkyl glucoside kunempembelelo entle ekunyibilikeni kwealkali kunye nesiphumo samaza seenwele.

I-adsorption ye-alkyl glycosides kwizinwele inokubonakaliswa ngokuthe ngqo kunye nekhwalithi nge-X-ray photoelectron spectroscopy (XPS) . Hlukanisa iinwele kwisiqingatha kwaye udibanise iinwele kwisisombululo se-12% ye-sodium lauryl polyether sulfate kunye ne-lauryl glucoside surfactant kwi-pH 5.5, Emva koko uhlambulule kwaye wome.Zombini ii-surfactants zinokuvavanywa kwimigangatho yeenwele zisebenzisa i-XPS.Ketone kunye nemiqondiso ye-oksijini ye-ether zisebenza ngakumbi kuneenwele ezingaphendulwanga.Ngenxa yokuba le ndlela inovakalelo nakwizixa ezincinci ze-adsorbents, ishampu enye kunye nokuhlanjululwa akwanelanga ukwahlula. phakathi kwe-surfactants ezimbini.Nangona kunjalo, ukuba inkqubo iphinda iphindwe kane, isibonakaliso se-XPS asitshintshi kwimeko ye-sodium laureth sulfate xa kuthelekiswa neenwele ezingaphendulwanga. Iziphumo zabonisa ukuba i-alkyl glucoside ibaluleke kakhulu kwizinwele kune-ether sulfate eqhelekileyo.

Ubudlelwane be-surfactant kwiinwele buchaphazela amandla okukama kweenwele.Iziphumo zibonise ukuba i-alkyl glucoside ayinayo impembelelo ebalulekileyo ekudibaniseni okumanzi.Nangona kunjalo, kwimixube ye-alkyl glycosides kunye neepolymers ze-cationic, ukucuthwa kwe-synergistic yeempawu zokubopha okumanzi kwakumalunga ne-50%. Ngokwahlukileyo, i-alkyl glucosides iphucule kakhulu ukomiswa.

Intsebenziswano eyongeziweyo kunye neempawu zokwenza ifilimu nazo zinegalelo kwimpembelelo yesitayile.I-omni-directional bounce yenza ukuba iinwele zibonakale zinamandla kwaye ziguquguqukayo.Ukuziphatha okubuyiswayo kwee-curls zeenwele kunokumiselwa ngovavanyo oluzenzekelayo (Umfanekiso 8) ofunda iimpawu ze-torsion. iintambo zeenwele (i-modulus egobayo) kunye nee-curls zeenwele (i-tensile force, attenuation, frequency and amplitude of oscillations) .I-free attenuation oscillation force force function yarekhodwa ngesixhobo sokulinganisa (i-inductive force sensor) kwaye iqhutywe yikhompyutha.Imveliso ye-Modeling yandisa intsebenziswano phakathi Imicu yeenwele, yonyusa ukomelela kwe-curl vibration tensile, amplitude, frequency and attenuation value.

Kwizinto zokuthambisa kunye nabalawuli bee-alcohols ezinamafutha kunye ne-quaternary ammonium compounds, i-synergistic effect ye-alkyl glucoside / i-quaternary ammonium compounds yayiluncedo ekunciphiseni ipropati ebophelelayo emanzi, ngelixa ipropati yokubopha okomileyo yayincitshiswe nje kancinci.Izithako ze-oyile nazo zinokongezwa ifomula yokunciphisa ngakumbi umxholo ofunekayo we-formaldehyde kunye nokuphucula ukukhanya kweenwele.Le emulsion yamanzi yeoli ingasetyenziselwa "ukuhlanjululwa" okanye "ukubamba" iinwele ukulungiselela ukulungiswa kwangemva kokunyanga.
