| Classic types of surfactants are produced from petrochemical raw materials. In the long term, fossil feedstocks will be exhausted and products based on renewable materials will become more important. Growing consumer demands for "natural" products have also directed the search for new surfactants towards renewable sources. Carbohydrate based surfactants such as sorbitan esters, sucrose esters, alkylpolyglycoside (APG) and fatty acid glucamides gain increasing attention due to advantage with regards to performance, health of consumers and environmental compatibility compared to some standard products. APG is the most important developing surfactants and also used as raw material for the development of specialty surfactants based on APG is arousing considerable interest. In this present work ionic derivative like carboxylate and sulfosuccinate of APG were prepared and evaluated for their surface active properties and compared with conventional surfactants. Low interfacial tensions, good wetting behavior and abundance foaming make them attractive for many technical applications. |
