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 bubuye bubonakale ekunakekelweni kwezinwele ezilimele.Uma kuqhathaniswa nesisombululo esijwayelekile se-etheric acid, isixazululo se-alkyl glucoside sokuvumela amandla aqinile wokunciphisa kuncane kakhulu. khombisa ukuthi ukungezwa kwe-alkyl glucoside kunomphumela 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 sika-12% we-sodium lauryl polyether sulfate kanye ne-lauryl glucoside surfactant ku-pH 5.5, bese ugeza izinwele phezu kwe-pH 5.5. I-XPS.Izimpawu ze-Ketone ne-ether oxygen zisebenza kakhulu kunezinwele ezingaphenduliwe.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 nokuqukethwe kwe-oksijini ye-laur ekhuphukayo engasebenzi kanye ne-glucool ye-oksijini ekhuphuka ngokungafani kokuqukethwe kwe-oksijeni ye-laur. kancane.Imiphumela yabonisa ukuthi i-alkyl glucoside yayinamandla kakhulu ezinweleni kune-ether sulfate evamile.

Ukuhlobana kwe-surfactant nezinwele kuthinta ikhono lekama lezinwele. Imiphumela ibonise ukuthi i-alkyl glucoside ayinawo umthelela obalulekile ekuhlanganisweni okumanzi. Nokho, ezixubeni zama-alkyl glycosides nama-cationic polymers, ukuncishiswa kwe-synergistic kwezakhiwo zokubopha okumanzi kwakucishe kube ngu-50%. zezinwele.

Ukwanda kokusebenzelana kanye nezakhiwo zokwenza ifilimu nakho kunomthelela emphumeleni wesitayela.I-omni-directional bounce yenza izinwele zibonakale zinempilo futhi ziguquguquka.Ukuziphatha okuphindaphindayo kwama-curls ezinwele kunganqunywa ngokuhlolwa okuzenzakalelayo (Umfanekiso 8) okucwaninga izici zokugoqa zemicu yezinwele (i-modulus egobayo) kanye nama-hair curls (amandla aqinile, ukuncishiswa, ukuncishiswa kwe-frequency oll all). ukusebenza kwe-force kwarekhodwa insimbi yokulinganisa (inzwa yamandla e-inductive) futhi yacutshungulwa yikhompuyutha.Imikhiqizo yokumodela yandisa ukusebenzisana phakathi kwemicu yezinwele, ikhuphula amandla okunyakazisa okunyakazisa kwe-curl, i-amplitude, imvamisa kanye nenani lokunciphisa.

Kuma-lotion kanye nabalawuli be-fatty alcohols kanye ne-quaternary ammonium compounds, umphumela we-synergistic we-alkyl glucoside/quaternary ammonium compounds ube nenzuzo ekunciphiseni impahla ebophayo emanzi, kuyilapho impahla ebophayo eyomile yancishiswa kancane kuphela.Izithako zikawoyela zingaphinda zengezwe kufomula ukuze kuqhutshekwe kuncishiswe okuqukethwe okudingekayo kwe-formaldehyde nokuthuthukisa uwoyela-amanzi angasetshenziswa" acwebezelise izinwele ". izinwele zokulungiselela ngemuva kokwelashwa.
