NONIONIC SURFACTANT, DIMER ACID ALKYLENE OXIDE BASED ON VEGETABLE OIL AND PREPARATION METHOD THEREOF

摘要

The present invention relates to a dimer acid alkylene oxide-based nonionic surfactant derived from vegetable oil and a preparation method thereof, wherein the surfactant is environmentally friendly and improves emulsification by containing hydrophilic groups such as hydroxyl groups and hydrophobic groups such as cyclic hydrocarbon groups by preparing dimer acid alkylene diol ester by making dimer acid thermally polymerized in vegetable oil react with alkylene diol and adding alkylene oxide thereto.
