Title:
NOVEL BETULIN DERIVATIVES, AND THEIR MANUFACTURING METHOD AND USE AS SURFACTANT
Document Type and Number:
WIPO Patent Application WO/2023/149727
Kind Code:
A1
Abstract:
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.
