Izakhiwo zokusebenza ze-Alkyl Polyglycosides Emikhiqizweni Yokunakekela Umuntu

• Igxila

Ukwengezwa kwe-alkyl polyglycosides kushintsha i-rheology yezingxube ze-surfactant ezigxilile ukuze kulungiswe ukugxilisa okumpompeka, okungalondolozi futhi okuncibilika kalula okuqukethe kufikela ku-60% wento esebenzayo.

Ingxube egxilile yalezi zithako ivame ukusetshenziswa njengesithako sezimonyo noma, ikakhulukazi, njengokugxilwa okuyisisekelo ekukhiqizeni izimonyo (isb. ishampoo, i-shampoo concentrate, ukugeza amagwebu, ukugeza umzimba, njll.).

Ngakho-ke, ama-alkyl glucosides asekelwe kuma-anion asebenza kakhulu njenge-alkyl ether sulphates (i-sodium noma i-ammonium), ama-Betaines kanye/noma ama-non-ionic surfactants ngakho-ke athambile kakhulu emehlweni nasesikhumbeni kunezinhlelo zendabuko.Ngasikhathi sinye, zikhombisa ukusebenza okuhle kakhulu kwegwebu, ukuqina nokusebenza kokucubungula.Ukugxilisa okuphezulu kukhethwa ngenxa yezizathu zezomnotho ngoba kulula ukuphatha nokuhlanjululwa futhi akuqukethe i-hydrogen.Isilinganiso sokuxuba sesisekelo se-surfactant siguqulelwa kuzidingo zokusebenza kokwakheka.

•  Umphumela wokuhlanza

Ukusebenza kokuhlanza kwama-surfactants kungafaniswa ngokuhlolwa okulula.I-epidermis yengulube ephathwe ngengxube ye-sebum kanye ne-surfactant yentuthu yawashwa ngesisombululo se-3% se-surfactant imizuzu emibili.Ebangeni le-microscopic, inani elimpunga linqunywa ukuhlaziywa kwesithombe sedijithali futhi liqhathaniswa nesikhumba sengulube esingalashiwe.Le ndlela ikhiqiza amazinga alandelayo wezakhiwo zokuhlanza: i-lauryl glucoside ikhiqiza imiphumela engcono kakhulu, kuyilapho i-coconut amphoteric acetate ikhiqiza imiphumela emibi kakhulu.I-Betaine, i-sulfosuccinate kanye ne-alkyl ether sulfate evamile zisebangeni eliphakathi futhi azikwazi ukuhlukaniswa ngokucacile kusuka kwenye yazo.Kulokhu kuhlanganiswa okuphansi, i-lauryl glucoside kuphela enomphumela ojulile wokuhlanza izimbotshana.

• Imiphumela ezinweleni

Ubumnene be-alkyl glycosides esikhumbeni bubonakala nasekunakekelweni kwezinwele ezonakele.Uma kuqhathaniswa nesisombululo esijwayelekile se-etheric acid, isixazululo se-alkyl glucoside sokuvumela amandla aqinile wokunciphisa kuncane kakhulu.I-Alkyl polyglycosides ingasetshenziswa futhi njengama-surfactants ekudayeni , ama-wave proofing kanye nama-bleaching agents ngenxa yokugcinwa kwawo kahle kwamanzi kanye nokuzinza kwe-alkali.Ucwaningo lwefomula yegagasi engaguquki lubonisa ukuthi ukungezwa kwe-alkyl glucoside kunomthelela omuhle ekuncibilikeni kwe-alkali kanye nomphumela wamagagasi wezinwele.

I-adsorption ye-alkyl glycosides ezinweleni ingafakazelwa ngokuqondile nangokwekhwalithi nge-X-ray photoelectron spectroscopy (XPS). Hlukanisa izinwele zibe uhhafu bese ucwilisa izinwele kusixazululo esingu-12% se-sodium lauryl polyether sulfate kanye ne-lauryl glucoside surfactant ku-pH 5.5, bese ugeza futhi wome.Zombili izisetshenziswa ezisetshenziswayo zingahlolwa ezindaweni eziphakeme zezinwele kusetshenziswa i-XPS.Izimpawu ze-ketone ne-ether oxygen zisebenza kakhulu kunezinwele ezingalashiwe.Ngenxa yokuthi le ndlela izwela ngisho namanani amancane ama-adsorbents, i-shampoo eyodwa kanye nokugeza akwanele ukuhlukanisa phakathi kwama-surfactants amabili.Nokho, uma inqubo iphindaphindiwe izikhathi ezine, isignali ye-XPS ayishintshi esimweni se-sodium laureth sulfate uma kuqhathaniswa nezinwele ezingalashwa. imiphumela yabonisa ukuthi i-alkyl glucoside yayibaluleke kakhulu ezinweleni kune-ether sulfate evamile.

Ukuhlobana kwe-surfactant nezinwele kuthinta ikhono lekama lezinwele.Imiphumela yabonisa ukuthi i-alkyl glucoside yayingenawo umthelela obalulekile ekuhlanganisweni okumanzi.Nokho, ezixubeni zama-alkyl glycosides nama-cationic polymers, ukuncishiswa kwe-synergistic kwezakhiwo zokubopha okumanzi kwakucishe kube ngu-50%. Ngokuphambene, i-alkyl glucosides ithuthukise kakhulu ukoma.Ukusebenzelana phakathi kwezintambo zezinwele zomuntu ngamunye kwandisa ivolumu nokuphathwa kwezinwele.

Ukwanda kokusebenzelana kanye nezakhiwo zokwenza ifilimu nakho kunomthelela emphumeleni wesitayela.I-omni-directional bounce yenza izinwele zibonakale zidlangile futhi ziguquguquka.Ukuziphatha okubuyela emuva kwama-curl ezinwele kunganqunywa ukuhlolwa okuzenzakalelayo (Umfanekiso 8) ocwaninga izici ze-torsion. imicu yezinwele (i-modulus egobayo) kanye nama-curls wezinwele (amandla aqinile, ukunciphisa, imvamisa kanye ne-amplitude ye-oscillations). imicu yezinwele, yandisa amandla okunyakazisa ama-curl, i-amplitude, imvamisa kanye nenani lokunciphisa.

Ezakhiweni nasezilawulweni zotshwala obunamafutha kanye nezinhlanganisela ze-quaternary ammonium, umthelela we-synergistic we-alkyl glucoside/quaternary ammonium compounds ube nenzuzo ukunciphisa impahla ebophayo emanzi, kuyilapho impahla ebophayo eyomile yehliswa kancane.Izithako zikawoyela nazo zingangezwa ifomula ukuze kuqhutshekwe nokunciphisa okuqukethwe kwe-formaldehyde okudingekayo futhi kuthuthukiswe izinwele ezikhazimulayo.Le emulsion yamanzi kawoyela ingasetshenziselwa "ukugeza" noma "ukubamba" izinwele zokulungiselela emva kokwelashwa.
