Product details:

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.

Description:

DDAB, or dodecyltrimethylammonium bromide, is a cationic surfactant with various properties that make it useful in a wide range of applications.

1. Structure: DDAB has a hydrophilic head consisting of a quaternary ammonium group and a hydrophobic tail composed of a dodecyl chain. This amphiphilic structure allows DDAB to interact with both polar and nonpolar substances.

2. Surfactant behavior: DDAB exhibits surfactant behavior due to its ability to lower the surface tension of liquids. It forms micelles in aqueous solutions, with the hydrophilic heads facing outward and the hydrophobic tails forming the core.

3. Cationic charge: DDAB carries a positive charge, which makes it attracted to negatively charged surfaces or molecules. This property allows it to adsorb onto surfaces, interact with charged particles, and modify the properties of materials.

4. Solubility: DDAB is soluble in water and organic solvents, such as ethanol and chloroform. Its solubility in water is influenced by factors such as temperature, concentration, and the presence of other substances.

Storage conditions:

Store at - 20 ℃. Avoid frequent thawing and freezing.
