Di-n-decyldimethylammonium Bromide(DDAB) Datasheet DC Chemicals
Description
DDAB, also known as dodecyltrimethylammonium bromide, is a cationic surfactant with specific solubility, stability, and storage conditions.
1. Solubility: DDAB is soluble in water and organic solvents such as ethanol and chloroform. It forms clear solutions in water, but can become turbid at high concentrations or low temperatures. It has a higher solubility in organic solvents compared to CTAB.
2. Stability: DDAB is relatively stable under normal storage conditions. However, it can undergo degradation and lose its surfactant properties if exposed to extreme temperatures, humidity, or oxidizing agents for extended periods. It is important to store DDAB in a cool, dry place away from direct sunlight.
3. Storage conditions: DDAB should be stored in a tightly sealed container to prevent moisture absorption and contamination. It is recommended to store it at room temperature (around 20-25°C) or in a refrigerator (2-8°C) to maintain its stability and extend its shelf life.
