Abstract
Aqueous-alcoholic solutions of hydrogenated coconut or palm kernel oil alkylamidopropylbetaines with a betaine content of greater than 50%, which are fluid, stable and pumpable are described as occupying a well-defined zone of their betaine/water/ethanol ternary diagram. They are prepared by synthesis and quaternization of the amidoamine directly in the solvent medium in which they are defined.
