Product Details
Dodecyl dimethyl benzyl ammonium chloride (commonly referred to as 1227) is a multifunctional cationic surfactant. In its typical form, it presents as a colorless to slightly yellow, viscous, and transparent liquid. High-purity grades of this product can also be obtained as white waxy solids or colloids. During storage, fish eyeball-like crystals may form; this is a normal phenomenon and does not affect the product's performance.
