Alkyl glucoside kana Alkyl Polyglycoside chigadzirwa cheindasitiri chinozivikanwa uye chave chiri chigadzirwa chekutarisa kwedzidzo kwenguva yakareba. Anopfuura makore zana apfuura, Fischer Synthesized uye akaziva yekutanga alkyl glycosides murabhoritari, anenge 40years gare gare, yekutanga patent application inotsanangura kushandiswa kwealkyl glycosides mu detergents yakaiswa kuGermany. Mushure meiyo 40-50years anotevera, zvimwe zvikwata zvemakambani zvinotendeudzira pfungwa dzavo kune alkyl glycosides uye akagadzira maitiro ekuagadzira zvichibva panzira dzakawanikwa naFischer.
Muchiitiko ichi, basa rekutanga raFischer pamusoro pekuita kweglucose ne hydrophilic alcohols (yakadai se methanol, ethanol, glycerol, nezvimwewo) yakashandiswa kune hydrophobic alcohols nemaketani ealkyl, kubva ku octyl (C8) kusvika kune hexadecyl (C16) iyo inowanzo mafuta. doro.
Neraki, nekuda kwezvivakwa zvekushandisa, kugadzirwa kwemaindasitiri hakusi kuchena alkyl monoglucosides, asi musanganiswa wakaoma wealkyl mono-, di-, tri-uye oligoglycosides, unogadzirwa mumaindasitiri maitiro. Nekuda kweizvi, zvigadzirwa zvemaindasitiri zvinonzi alkyl polyglycosides, zvigadzirwa zvinoratidzwa nehurefu hweketani yealkyl uye avhareji yenhamba yeglycose units yakabatana nayo, dhigirii repolymerization.

Rohm&Haas yaive kambani yekutanga kuita kugadzirwa kwakawanda kweoctyl/decyl(C8~C10) glycosides mukupera kwema1970, ichiteverwa neBASF neSEPPIC. Nekudaro, nekuda kwekusagutsikana kwekuita kweiyi pfupi-ketani uye yakashata yemhando yemhando, kushandiswa kwayo kunogumira kune mashoma emusika zvikamu, senge maindasitiri nemasangano.
Hunhu hweiyi shor-chain alkyl glycoside hwakavandudzwa mumakore mashoma apfuura uye akati wandei makambani ari kupa octyl/decyl glycosides matsva, anosanganisira BASF, SEPPIC, Akzo Nobel, ICI neHenkel.
Mukutanga kwema1980, makambani akati wandei akatanga kugadzira alkyl glycosides mune yakarebesa alkyl chain range (dodecyl/tetradecyl, C12~C14) kuitira kuti ape mutsva wesurfactant weindasitiri yezvizoro uye yekugezesa. Vaisanganisira Henkel KGaA, Diisseldorf, Germany, uye Horizon, chikamu cheAEStaley Manufacturing Company yeDecatur,IIlinois, USA.
Kushandisa Horizon kuziva-maitiro akawanikwa panguva imwe chete, pamwe neruzivo rwaHenkel KGaA kubva mukutsvagisa nekusimudzira muDiisseldorf. Henkel akagadzira chirimwa chekutyaira kugadzira alkyl polyglycosides muCrosby, Texas. Kukwanisa kugadzira chirimwa chaive 5000 t pa, uye chave chichiitwa muna1988 na1989. Chinangwa chemutyairi-chirimwa ndechekuwana maparamendi uye kukwidziridza mhando uye kurima musika weiyi itsva surfactant.
Munguva kubva 1990 kusvika 1992, mamwe makambani akazivisa kufarira kwavo kugadzira alkyl polyglycosides (C12-C14), kusanganisira Chemische werke Hiils, ICI, Kao, SEPPIC.
Muna 1992, Henkel yakagadzira chirimwa chitsva muUSA kuti chigadzire Alkyl polyglucosides uye kugona kwayo kugadzira kwakasvika pa 25000t pa Henkel KGaA yakatanga kumhanyisa chirimwa chechipiri chine hunyanzvi hwekugadzira mu1995.
