Novel betulin derivatives, and their manufacturing method and use as surfactant
Betulin is a natural pentacyclic triterpene, and is contained in birch tree, especially its outer bark. Betulin can be used as a hydrophobic building block for production of biobased surfactants. This invention is related to amphiphilic betulin derivatives, and their efficient production method. And resulting materials can be used as biobased surfactants.
