Application
DDAO is a non-denaturing zwitterionic surfactant with a critical micelle
concentration (CMC) or approximately 1 mM. It is used to solubilize pro-
teins and to study the conformation and molecular interactions of mac-
romolecules. This grade is highly suitable for Pharmaceutical applica-
tions, especially in Dissolution Testing for Quality Control.
