n-Dodecyl-B-D-Maltoside, or DDM, is a maltoside based non-ionic detergent with a hydrophilic maltose head and a hydrophobic long chain alkyl tail. It is considered a gentle detergent that is more efficient than other detergents, such as CHAPS or NP-40. It has a comparatively low critical micelle concentration (CMC) of 0.17mM compared to the other maltoside based detergents.
