Abstract (en)
[origin: FR2770841A1] The invention concerns fluid, stable and pumpable hydroalcoholic solutions of copra or oil palm alkyl-amidopropylbetains with betain content higher than 50 % occupying a well defined zone in their ternary diagram betain/water/ethanol. Said solutions are prepared by synthesis and quaternization of amidoamine directly in the solvent medium wherein they are defined.
