Alkyl Polyglycosides hauv Cov Khoom Kho Tus Kheej

Ntau xyoo dhau los, kev tsim cov khoom siv raw rau cov khoom siv tu tus kheej tau nce mus rau peb qhov tseem ceeb:

(1) kev ua siab mos thiab saib xyuas ntawm daim tawv nqaij

(2) cov qauv zoo los ntawm kev txo qis ntawm cov khoom lag luam thiab cov kab tsis huv

(3) ecological compatibility.

Cov kev cai lij choj thiab cov neeg siv khoom xav tau yog nce ntxiv kev tsim kho tshiab uas ua raws li cov qauv txheej txheem thiab cov khoom lag luam sustainability.Ib qho ntawm cov ntsiab lus no yog kev tsim cov alkyl glycosides los ntawm cov roj zaub thiab carbohydrates los ntawm cov khoom siv txuas ntxiv.Txoj kev loj hlob ntawm kev lag luam thev naus laus zis yuav tsum muaj kev tswj hwm qib siab ntawm cov khoom siv raw, cov tshuaj tiv thaiv thiab kev ua haujlwm kom ua tau raws li qhov yuav tsum tau ua ntawm cov khoom siv niaj hnub kom zoo nkauj thiab tsim lawv ntawm tus nqi tsim nyog.Hauv kev lag luam tshuaj pleev ib ce, alkyl glucoside yog ib hom tshiab ntawm surfactant nrog cov khoom tsis-ionic thiab anionic.Txog rau tam sim no, cov khoom lag luam loj tshaj plaws yog cov tshuaj ntxuav tes uas sawv cev los ntawm C8-14 alkyl glycosides, uas yog cov yam ntxwv ntawm lawv cov tawv nqaij thiab cov plaub hau tu.C12-14 alkyl polyglycoside ua ib qho emulsifier hauv cov qauv tshwj xeeb thiab tshwj xeeb hauv microemulsions thiab kawm txog kev ua tau zoo ntawm C16-18 alkyl polyglycoside ua tus kheej-emulsifying o / w puag sib xyaw nrog roj cawv.

Rau lub cev cleansing formulations, ib tug tshiab niaj hnub surfactant yuav tsum muaj zoo compatibility nrog daim tawv nqaij thiab mucous daim nyias nyias.Kev ntsuam xyuas dermatological thiab toxicological yog qhov tsim nyog los ntsuas qhov kev pheej hmoo ntawm cov surfactant tshiab thiab tsim qhov tseem ceeb tshaj plaws los txheeb xyuas qhov muaj peev xwm ntawm cov hlwb nyob hauv cov txheej txheem epidermal basal.Yav dhau los, qhov no yog lub hauv paus ntawm surfactant mildness thov.Nyob rau tib lub sijhawm, lub ntsiab lus ntawm kev ua siab mos siab tau hloov pauv ntau.Hnub no, kev ua siab mos siab tau nkag siab tias yog kev ua tiav ntawm surfactants nrog lub cev thiab kev ua haujlwm ntawm tib neeg cov tawv nqaij.

Los ntawm ntau yam dermatological thiab biophysical txoj kev, physiological teebmeem ntawm surfactants ntawm daim tawv nqaij tau kawm, pib ntawm daim tawv nqaij thiab nce mus rau lub tob txheej ntawm basal hlwb los ntawm lub stratum corneum thiab nws barrier muaj nuj nqi. Tib lub sij hawm, subjective sensations , xws li kev xav ntawm daim tawv nqaij, raug kaw los ntawm cov lus ntawm kev kov thiab kev paub.

Alkyl polyglycosides nrog C8 rau C16 alkyl chains belongs rau pab pawg neeg ntawm me me surfactants rau lub cev cleansing formulations.Hauv kev tshawb fawb ntxaws, qhov sib xyaw ntawm alkyl polyglycosides tau piav qhia raws li kev ua haujlwm ntawm cov ntshiab alkyl saw thiab qib ntawm polymerization.In the modified Duhring Chamber Test, C12 alkyl polyglycoside qhia tau hais tias tus txheeb ze siab tshaj plaws nyob rau hauv thaj tsam ntawm qhov mob me me ects whereas C8, C10 thiab C14, C16 alkyl polyglycoside tsim cov qhab nia qis dua.Qhov no sib raug rau kev soj ntsuam nrog lwm cov chav kawm ntawm surfactants.Tsis tas li ntawd, kev khaus khaus me ntsis nrog kev nce qib ntawm polymerization (los ntawm DP = 1.2 txog DP = 1.65).

APG cov khoom uas sib xyaw alkyl saw ntev muaj qhov zoo tshaj plaws zuag qhia tag nrho compatibility nrog ib tug ntau dua feem ntawm ntev alkyl glycosides (C12-14). - fatty acids ntawm collagen los yog nplej proteolytic tshuaj.

Cov kev tshawb pom dermatological nyob rau hauv caj npab flex ntxuav tes qhia tib yam qeb duas xws li hauv kev hloov kho Duhring Chamber Test qhov twg cov tshuab sib xyaw ntawm cov qauv alkyl ether sulfate thiab alkyl polyglycosides lossis amphoteric co-surfactants raug tshawb xyuas.Txawm li cas los xij, lub caj npab flex wash test tso cai rau kev sib txawv ntawm cov teebmeem zoo dua.Kev tsim ntawm erythema thiab squamation tuaj yeem txo los ntawm 20-30 D / o yog tias nyob ib ncig ntawm 25 ° 10 ntawm SLES yog hloov los ntawm alkyl polyglycoside uas qhia tias txo qis ntawm 60%.Nyob rau hauv lub systematic build-up ntawm ib tug formulation, qhov zoo tshaj plaws yuav ua tau tiav los ntawm kev ntxiv cov protein derivatives los yog amphoterics.
