Product Overview
Hexadecyl trimethyl ammonium bromide (CTAB, CAS 57-09-0) is a typical cationic surfactant and quaternary ammonium salt. It appears as white crystalline powder with slight characteristic odor. It possesses excellent surface activity, bactericidal, emulsifying, dispersing and flocculating properties, and shows good compatibility with partial nonionic surfactants. Manufactured via advanced synthesis and recrystallization technology, the product features high purity, low impurities and stable batch quality. Widely used in daily chemicals, biochemical research, water treatment and organic synthesis fields. For legitimate industrial production, formulation and scientific research only.
