Lactose‐ derived surfactants(III): Fatty esters of oxyalkylated lactito

Abstract and Summary Lactitol was oxyalkylated with propylene or ethylene oxide. The resulting ether‐alcohols were transesterified with a series of fatty acid esters in order to produce long chain ether‐esters of lactitol. These compounds were found to be more water soluble than related lactitol derivatives prepared by transesterification prior to oxyalkylation. Improved lime soap dispersant requirements (LSDR) and emulsification times were obtained from the new derivatives.
