Preparation and properties of pure alkyl glucosides, maltosides and maltotriosides

Alkyl β ‐D‐glycopyranosides composed of glucose, maltose or maltotriose attached to alkyl groups having from 4 to 18 carbon atoms were synthesized and tested for their physical and functional properties. Values are given for melting points, optical rotations, detergencies, critical micelle concentrations, surface tensions, interfacial surface tensions, Draves wetting tests and Ross Miles foam tests. Results show that maximum cleaning was obtained with maltosides attached to straight chain alkyl groups having from 12 to 15 carbon atoms.
