Alkyl glucoside lossis Alkyl Polyglycoside yog cov khoom lag luam paub zoo thiab tau ua ib yam khoom ntawm kev kawm tsom mus ntev.Ntau tshaj 100 xyoo dhau los, Fischer Synthesized thiab txheeb xyuas thawj alkyl glycosides hauv chav kuaj, txog 40 xyoo tom qab, thawj daim ntawv thov patent piav qhia txog kev siv cov alkyl glycosides hauv cov tshuaj ntxuav tes tau thov hauv Tebchaws Yelemees.Tom qab 40-50 xyoo tom ntej no, qee pawg tuam txhab lag luam tig lawv cov xim rau alkyl glycosides thiab tsim cov txheej txheem los tsim lawv raws li cov txheej txheem synthesis Fischer nrhiav pom.
Hauv qhov kev txhim kho no, Fischer txoj haujlwm thaum ntxov ntawm cov tshuaj tiv thaiv ntawm cov piam thaj nrog hydrophilic alcohols (xws li methanol, ethanol, glycerol, thiab lwm yam) tau siv rau hydrophobic alcohols nrog alkyl chains, xws li octyl (C8) mus rau hexadecyl (C16) cov roj ntsha raug. cawv.
Hmoov zoo, vim lawv cov khoom siv, kev tsim khoom lag luam tsis yog cov ntshiab alkyl monoglucosides, tab sis kev sib xyaw ntawm alkyl mono-, di-, tri- thiab oligoglycosides, yog tsim nyob rau hauv cov txheej txheem kev lag luam.Vim li no, cov khoom lag luam raug hu ua alkyl polyglycosides, cov khoom lag luam yog qhov ntev ntawm alkyl saw thiab qhov nruab nrab ntawm cov glycose units txuas rau nws, qib ntawm polymerization.

Rohm&Haas yog thawj lub tuam txhab khiav lag luam loj rau octyl / decyl (C8 ~ C10) glycosides thaum xyoo 1970s, ua raws BASF thiab SEPPIC.Txawm li cas los xij, vim qhov ua tsis tau zoo ntawm cov saw luv luv thiab cov xim tsis zoo, nws daim ntawv thov raug txwv rau ob peb ntu kev lag luam, xws li kev lag luam thiab chaw ua haujlwm.
Qhov zoo ntawm no shor-chain alkyl glycoside tau txhim kho nyob rau hauv ob peb xyoos dhau los thiab ntau lub tuam txhab tam sim no muab cov tshiab octyl/decyl glycosides, suav nrog BASF, SEPPIC, Akzo Nobel, ICI thiab Henkel.
Nyob rau xyoo 1980s, ntau lub tuam txhab pib tsim cov alkyl glycosides nyob rau hauv ib tug ntev alkyl saw range (dodecyl / tetradecyl, C12 ~ C14) thiaj li yuav muab ib tug tshiab surfactant rau cov tshuaj pleev ib ce thiab tshuaj ntxuav kev lag luam.Lawv suav nrog Henkel KGaA, Diisseldorf, Lub Tebchaws Yelemees, thiab Horizon, ib feem ntawm AEStaley Manufacturing Company ntawm Decatur, IIlinois, Tebchaws Asmeskas.
Siv Horizon paub-yuav tau txais tib lub sijhawm, nrog rau Henkel KGaA qhov kev paub los ntawm kev tshawb fawb thiab kev loj hlob hauv Diisseldorf.Henkel tau tsim ib lub chaw tsav tsheb los tsim cov alkyl polyglycosides hauv Crosby, Texas.Lub peev xwm ntau lawm ntawm cov nroj tsuag yog 5000 t pa, thiab tau taug kev hauv xyoo 1988 thiab 1989. Lub hom phiaj ntawm kev tsav-cog yog kom tau txais cov txheej txheem tsis zoo thiab ua kom zoo tshaj plaws thiab kev ua lag luam cog qoob loo rau qhov tshiab surfactant.
Thaum lub sijhawm xyoo 1990 txog 1992, lwm lub tuam txhab tshaj tawm lawv txoj kev txaus siab los tsim cov alkyl polyglycosides (C12-C14), suav nrog Chemische werke Hiils, ICI, Kao, SEPPIC.
Xyoo 1992, Henkel tau tsim cov nroj tsuag tshiab hauv Tebchaws Meskas los tsim Alkyl polyglucosides thiab nws cov peev txheej tsim tau mus txog 25000t pa Henkel KGaA pib khiav thib ob nrog tib lub peev xwm ntau lawm hauv xyoo 1995. Cov peev txheej ntau lawm ua rau cov peaks tshiab ntawm kev lag luam exploitation ntawm alkyl polyglycosides.
