“…Surfactants with a nonionic carbohydrate-derived headgroup (Figure ) have potential pharmaceutical (biocompatible formulation), biological (extraction of membrane proteins), and medicinal (antiviral activity) applications. − As is the case for other carbohydrate-derived surfactants (such as the alkyl polyglucosides and the aldonamides), , the compounds described here also possess excellent detergency properties. , We report the preparation of eight homologous series of these surfactants. The series are classified on the basis of the headgroup (either a glucose/glucitol or a lactose/lactitol headgroup) and the nature of the acyl substituent (acetyl (C 2 ) or propionyl (C 3 )), and each series consists of three surfactant molecules with C 8 , C 10 , and C 12 alkyl chains.…”

Complexes between β-Cyclodextrin and Aliphatic Guests as New Noncovalent Amphiphiles: Formation and Physicochemical Studies

“…Nonionic surfactants based on sugars have many prospects and actual applications in both chemistry and biochemistry. − In addition to performance, there is a growing demand for surfactants which are also environmentally friendly and produced from renewable resources. In particular, alkylpolyglucosides (APGs) are being increasingly developed, − as in addition they have good dermatological compatibility and biodegradability. Although effective at low temperatures, their development is nevertheless limited by their hydrophilic/lipophilic balance (HLB) which does not reach values as high as those obtained with ethylene oxide derivatives.…”

The 1-Monooleoyl-rac-glycerol/n-Octyl-β-d-Glucoside/Water System. Phase Diagram and Phase Structures Determined by NMR and X-ray Diffraction

“…Alkylglucosides (AGs) are nonionic surfactants that can be synthesized from renewable resources, and they are usually biodegradable . They are regarded as mild surfactants, suitable for a number of applications such as washing and cosmetic products as well as for solubilizing and reconstitution of membrane proteins. − Though AGs have been known for more than a century, , they have been less studied than the poly(ethylene oxide)-based surfactants. In many respects AGs do behave similar to the poly(ethylene oxide)-based surfactants, but there are also significant differences. , A lot of work has been published on commercial products, which often contain mixtures of AGs with different chain lengths and headgroups, having more than one glucoside unit.…”
