Didodecyl dimethyl ammonium chloride CAS#3401-74-9
Didecyl dimethyl ammonium chloride (DDAC) is available in two main specifications: the 80% concentration appears as a colorless to pale yellow liquid, while the 99% concentration is an off-white paste.
It is highly soluble in polar solvents but slightly soluble in water. It exhibits excellent antistatic, anticorrosive, dispersing, emulsifying, and foaming properties.
Compatible with cationic, nonionic, and amphoteric surfactants, it adsorbs onto negatively charged surfaces—rendering fibers soft, fluffy, and hydrophobic
