Synthesis and characterisation of maltosides and lactosides based on alcohol mixtures obtained from palm oil and palm kernel oil / Nurul Fadhilah binti Kamalul Aripin

The headgroup of these glycolipids, which consist of a dissacharide i.e. maltose and lactose, provide good hydrophilicity. These glycolipids are comparable to alkyl polyglucosides (APGs), a common non-ionic surfactant used for detergents, particularly in the cosmeceutical industry. APGs are limited...
