Alkyl glucoside kapa Alkyl Polyglycoside ke sehlahisoa se tsebahalang sa indasteri mme esale e le sehlahisoa se tloaelehileng sa ho tsepamisa maikutlo ho sona ka nako e telele. Lilemong tse fetang 100 tse fetileng, Fischer Synthesized le ho tsebahatsa li-alkyl glycosides tsa pele ka laboratoring, hoo e ka bang lilemo tse 40 hamorao, kopo ea pele ea patent e hlalosang tšebeliso ea li-alkyl glycosides ho li-detergent e ile ea kenngoa Jeremane. Ka mor'a moo lilemong tse 40-50 tse latelang, lihlopha tse ling tsa lik'hamphani li lebisa tlhokomelo ea tsona ho alkyl glycosides 'me li ntlafalitse mekhoa ea ho li hlahisa ho latela mekhoa ea ho kopanya Fischer.
Ts'ebetsong ena, mosebetsi oa pele oa Fischer mabapi le karabelo ea tsoekere ka li-alcohol tsa hydrophilic (joalo ka methanol, ethanol, glycerol, joalo-joalo) e ile ea sebelisoa ho lino tse tahang tsa hydrophobic tse nang le liketane tsa alkyl, ho tloha ho octyl (C8) ho ea ho hexadecyl (C16) mafura a tloaelehileng. lino tse tahang.
Ka lehlohonolo, ka lebaka la thepa ea bona ea kopo, tlhahiso ea indasteri ha se li-alkyl monoglucosides tse hloekileng, empa motsoako o rarahaneng oa alkyl mono-, di-, tri-le oligoglycosides, o hlahisoa lits'ebetsong tsa indasteri. Ka lebaka la sena, lihlahisoa tsa indasteri li bitsoa alkyl polyglycosides, lihlahisoa li khetholloa ke bolelele ba ketane ea alkyl le palo e tloaelehileng ea likarolo tsa glycose tse amanang le eona, tekanyo ea polymerization.

Rohm&Haas e bile khamphani ea pele ea ho tsamaisa tlhahiso ea bongata bakeng sa octyl/decyl(C8~C10) glycosides ho elella bofelong ba lilemo tsa bo-1970, e lateloa ke BASF le SEPPIC. Leha ho le joalo, ka lebaka la ts'ebetso e sa thabiseng ea ketane ena e khutšoanyane le boleng bo bobe ba mebala, ts'ebeliso ea eona e lekanyelitsoe likarolong tse 'maloa tsa' maraka, tse kang tsa indasteri le tsa mekhatlo.
Boleng ba shor-chain alkyl glycoside bo ntlafalitsoe lilemong tse 'maloa tse fetileng mme lik'hamphani tse' maloa hajoale li fana ka li-octyl/decyl glycosides tse ncha, ho kenyeletsoa BASF, SEPPIC, Akzo Nobel, ICI le Henkel.
Mathoasong a lilemo tsa bo-1980, lik'hamphani tse 'maloa li ile tsa qala ho hlahisa li-alkyl glycosides sebakeng se selelele sa alkyl chain (dodecyl/tetradecyl, C12~C14) e le ho fana ka sehlahisoa se secha bakeng sa indasteri ea litlolo le litlolo. Li ne li kenyelletsa Henkel KGaA, Diisseldorf, Germany, le Horizon, e leng karolo ea AEStaley Manufacturing Company ea Decatur,IIlinois,USA.
Ho sebelisa tsebo ea Horizon e fumanoeng ka nako e le 'ngoe, hammoho le boiphihlelo ba Henkel KGaA ho tsoa lipatlisisong le nts'etsopele ea Diisseldorf. Henkel e thehile setsi sa lifofane ho hlahisa alkyl polyglycosides Crosby, Texas. Bokhoni ba tlhahiso ea polante e ne e le 5000 t pa, 'me esale e tsamaisoa ka 1988 le 1989. Sepheo sa setsi sa liteko ke ho fumana mekhoa ea ts'ebetso le ho ntlafatsa boleng le mmaraka oa ho lema bakeng sa sesebelisoa sena se secha.
Nakong ea 1990 ho isa 1992, lik'hamphani tse ling li phatlalalitse thahasello ea tsona ea ho hlahisa alkyl polyglycosides (C12-C14), ho kenyeletsoa Chemische werke Hiils, ICI, Kao,SEPPIC.
Ka 1992, Henkel e ile ea theha semela se secha USA ho hlahisa Alkyl polyglucosides 'me matla a tlhahiso ea eona a fihla ho 25000t pa Henkel KGaA e qalile ho tsamaisa semela sa bobeli se nang le bokhoni bo tšoanang ba tlhahiso ka 1995. Keketseho ea tlhahiso ea tlhahiso e etsa litlhōrō tse ncha tsa tšebeliso ea khoebo ea alkyl polyglycosides.
