Synthesis and properties of a glucono-δ-lactone-modified silicone surfactant from high-amine-value amodimethicone
Abstract High-amine-value aminopropyl polysiloxanes (APSO) were designed and synthesized via two different methods. APSO was then aminated with glucono-δ-lactone (GL) to produce sugar-modified amodimethicone (GLAP). The properties of GLAP were investigated systematically. GLAP has a low critical aggregation concentration (CAC) and displays low surface tensions at CAC (γCAC). GLAP forms spherical aggregates in solution. Formation of micelles and adsorption at the air-water interface are spontaneous. Moreover, its good solubility and excellent wetting properties make GLAP a potential candidate for application in paints, coatings, and agricultural adjuvants. Graphical Abstract
