Product Details
Didodecyl dimethyl ammonium chloride (also known as DDAC) with 80% concentration appears as a colorless to pale yellow liquid, while the 99% grade is an off-white paste. It dissolves readily in polar solvents but has low solubility in water. This product features outstanding antistatic, anti-corrosion, dispersion, emulsification, and foaming characteristics. It is compatible with cationic, nonionic, and amphoteric surfactants. When adsorbed onto negatively charged surfaces, it renders fibers soft, fluffy, and hydrophobic.
