Alkyl glucoside ma ọ bụ Alkyl Polyglycoside bụ ngwaahịa a ma ama nke ụlọ ọrụ mmepụta ihe ma bụrụkwa ngwaahịa a na-ahụkarị nke agụmakwụkwọ lekwasịrị anya na ogologo oge. Ihe karịrị 100 afọ gara aga, Fischer Synthesized ma chọpụta alkyl glycosides mbụ na ụlọ nyocha, ihe dị ka afọ 40 ka e mesịrị, akwụkwọ ikike mbụ nke na-akọwa iji alkyl glycosides na detergents na Germany. Mgbe afọ 40-50 na-esote, ụfọdụ ụlọ ọrụ na-atụgharị uche ha na alkyl glycosides ma mepụta usoro iji mepụta ha dabere na usoro njikọ Fischer chọpụtara.
Na mmepe a, ọrụ mbụ Fischer na mmeghachi omume nke glucose na hydrophilic alcohols (dị ka methanol, ethanol, glycerol, wdg) etinyere na hydrophobic alcohols nwere alkyl chains, sitere na octyl (C8) ruo hexadecyl (C16) ụdị abụba abụba. mmanya na-egbu egbu.
N'ụzọ dị mma, n'ihi ngwa ngwa ha, mmepụta mmepụta ihe abụghị alkyl monoglucosides dị ọcha, ma a na-emepụta ngwakọta mgbagwoju anya nke alkyl mono-, di-, tri-na oligoglycosides, na usoro mmepụta ihe.

Rohm & Haas bụ ụlọ ọrụ mbụ na-arụ ọrụ mmepụta ihe maka octyl/decyl (C8 ~ C10) glycosides na njedebe 1970, BASF na SEPPIC sochiri. Otú ọ dị, n'ihi arụmọrụ na-adịghị mma nke obere agbụ a na àgwà adịghị mma, ngwa ya na-ejedebe na mpaghara ahịa ole na ole, dị ka ụlọ ọrụ mmepụta ihe na ụlọ ọrụ.

Na mmalite 1980s, ọtụtụ ụlọ ọrụ malitere ịzụlite alkyl glycosides na ogologo alkyl chain range (dodecyl/tetradecyl, C12 ~ C14) iji nye ihe ọhụrụ surfactant maka ịchọ mma na ụlọ ọrụ ncha. Ha gụnyere Henkel KGaA,Diisseldorf,Germany na Horizon, ngalaba nke AEStaley Manufacturing Company of Decatur,Ilinois, USA.
Iji Horizon mara-esi enwetara n'otu oge, yana ahụmịhe Henkel KGaA sitere na nyocha na mmepe na Diisseldorf. Henkel guzobere osisi na-anya ụgbọ elu iji mepụta alkyl polyglycosides na Crosby, Texas. The mmepụta ike nke osisi bụ 5000 t pa, na e nzọ ụkwụ na-agba ọsọ na 1988 na 1989. Nzube nke pilot-osisi bụ iji nweta usoro parameters na ebuli àgwà na cultivating ahịa maka ọhụrụ a surfactant.

Na 1992, Henkel guzobere ọhụrụ osisi na USA na-emepụta Alkyl polyglucosides na ya mmepụta ikike ruru 25000t pa Henkel KGaA malitere na-agba ọsọ nke abụọ osisi na otu mmepụta ikike na 1995. Production ikike abawanye na-eme ka ọhụrụ ọnụ ọgụgụ kasị elu nke azụmahịa nrigbu nke alkyl polyglycosides.
