N-dodecyl-B-D-maltoside Powder CAS 69227-93-6

N-dodecyl-B-D-maltoside powder (DDM) is a typical glycosyl nonionic surfactant, composed of a hydrophobic n-dodecyl chain and a hydrophilic β-D-maltose group linked by a glycosidic bond. It possesses excellent amphiphilic molecular structure and natural biocompatibility. This substance is typically a white powder with good water solubility and a low critical micelle concentration. Under mild concentration conditions, it spontaneously self-assembles to form well-structured micelles and aggregates. Its molecular structure is stable, its surface activity is excellent, and it exhibits low irritation, low cytotoxicity, and good biocompatibility. It does not easily induce drastic conformational changes in biomolecules and can gently maintain the natural spatial structure of proteins and biomembrane systems.

With its moderate HLB value and excellent emulsifying, solubilizing, and dispersing abilities, it can efficiently construct oil-in-water nanoemulsions, micromicelles, and ordered assembly systems. It is widely used in the fields of molecular self-assembly mechanism research, maintenance of biomacromolecule structure, emulsion formulation construction, daily chemical emulsion systems, biomembrane simulation, and food colloid stabilization. It is also often used as a mild additive in fine chemical formulation, construction of biological separation media, and research and development of biomimetic interface systems. It is a highly representative functional raw material among bio-friendly surfactants.
