ʻO Alkyl glucoside a i ʻole Alkyl Polyglycoside kahi huahana ʻoihana kaulana a he huahana maʻamau o ka nānā ʻana i ka hoʻonaʻauao no ka manawa lōʻihi. ʻOi aku ma mua o 100 mau makahiki i hala aku nei, ua hana ʻo Fischer a ʻike i nā alkyl glycosides mua i loko o kahi keʻena hana, ma kahi o 40 mau makahiki ma hope mai, ua waiho ʻia ka palapala patent mua e wehewehe ana i ka hoʻohana ʻana i nā alkyl glycosides i nā mea holoi holoi. Ma hope o nā makahiki he 40-50 e hiki mai ana, huli kekahi mau hui o nā hui i nā alkyl glycosides a hoʻomohala i nā kaʻina hana e hana ai ma muli o nā ʻano synthesis i ʻike ʻia e Fischer.
I kēia hoʻomohala ʻana, ua hoʻohana ʻia ka hana mua a Fischer i ka hopena o ka glucose me nā waiʻona hydrophilic (e like me ka methanol, ethanol, glycerol, etc.) i nā waiʻona hydrophobic me nā kaulahao alkyl, mai ka octyl (C8) a i ka hexadecyl (C16) ka momona maʻamau. nā waiʻona.
ʻO ka mea pōmaikaʻi, ma muli o kā lākou noi noi, ʻaʻole ka alkyl monoglucosides maʻemaʻe ka hana ʻoihana, akā kahi hui paʻakikī o alkyl mono-, di-, tri-a me oligoglycosides, i hana ʻia i nā kaʻina hana. Ma muli o kēia, kapa ʻia nā huahana ʻoihana alkyl polyglycosides, ʻike ʻia nā huahana e ka lōʻihi o ke kaulahao alkyl a me ka helu awelika o nā ʻāpana glycose i hoʻopili ʻia me ia, ke ʻano o ka polymerization.

ʻO Rohm&Haas ka hui mua e holo i ka hana nui no ka octyl/decyl(C8~C10) glycosides i ka hopena o 1970s, a ukali ʻia e BASF a me SEPPIC. Eia nō naʻe, ma muli o ka hana maikaʻi ʻole o kēia kaulahao pōkole a maikaʻi ʻole ka maikaʻi o ka waihoʻoluʻu, ua kaupalena ʻia kāna noi i kekahi mau māhele mākeke, e like me nā ʻāpana ʻoihana a me nā ʻoihana.
Ua hoʻomaikaʻi ʻia ka maikaʻi o kēia shor-chain alkyl glycoside i nā makahiki i hala iho nei a ke hāʻawi nei kekahi mau hui i nā octyl/decyl glycosides hou, me BASF, SEPPIC, Akzo Nobel, ICI a me Henkel.
I nā makahiki 1980 mua, ua hoʻomaka kekahi mau hui e hoʻomohala i nā alkyl glycosides i loko o kahi laina kaulahao alkyl lōʻihi (dodecyl/tetradecyl, C12~C14) i mea e hoʻolako ai i kahi surfactant hou no ka ʻoihana hoʻonaninani a me ka ʻoihana holoi. Ua komo pū lākou me Henkel KGaA, Diisseldorf, Kelemānia, a me Horizon, he mahele o AEStaley Manufacturing Company o Decatur, IIlinois, USA.
Ke hoʻohana nei i ka ʻike Horizon i loaʻa i ka manawa like, a me ka ʻike o Henkel KGaA mai ka noiʻi a me ka hoʻomohala ʻana ma Diisseldorf. Ua hoʻokumu ʻo Henkel i kahi mea kanu hoʻokele e hana i nā alkyl polyglycosides ma Crosby, Texas. He 5000 t pa ka mana hana o ka mea kanu, a ua holo ia i ka makahiki 1988 a me 1989. ʻO ke kumu o ka mea kanu pilote, ʻo ia ka loaʻa ʻana o nā ʻāpana kaʻina hana a me ka hoʻonui ʻana i ka maikaʻi a me ka mākeke mahiʻai no kēia surfactant hou.
I loko o ka manawa mai 1990 a 1992, hoʻolaha nā hui ʻē aʻe i ko lākou makemake i ka hana ʻana i nā polyglycosides alkyl (C12-C14), me Chemische werke Hiils, ICI, Kao, SEPPIC.
I ka makahiki 1992, ua hoʻokumu ʻo Henkel i mea kanu hou ma USA e hana i nā polyglucosides Alkyl a hiki i ka 25000t pa Henkel KGaA hoʻomaka e holo i ka lua o ka mea kanu me ka mana hana like i ka makahiki 1995. Hoʻonui ka hiki ke hoʻonui i nā kiʻekiʻe o ka hoʻohana ʻana i nā alkyl polyglycosides.
