Uses & manufacturing
Uses
Formerly registered in the US for use as a floor disinfectant; [NPIRS]
Using Disinfectants or Biocides [Category: Clean]
General Manufacturing Information1-Dodecanaminium, N-dodecyl-N,N-dimethyl-, bromide (1:1): ACTIVE
Applications
Uses(Di-n-dodecyl)dimethylammonium bromide is used as a phase transfer catalyst. It is also used as floor disinfectant. Further, it acts as surface-active agent.
UsesDidodecyldimethylammonium bromide (DDAB) is a double-chain cationic surfactant.Possible applications:DDAB can be employed as a co-surfactant to synthesize well-defined multilamellar vesicular silica with an adjustable number of layers.As a surfactant to synthesize gold nanoclusters and nanocubes.It forms supersaturated reverse micelles and microemulsions that act as organized reaction microenvironments for the synthesis of barium sulfate.Calcium montmorillonite can be modified by DDAB through direct ion-exchange to synthesize thermally stable organoclay.
