Cetrimonium Chloride (CTAC), with the CAS number 112-02-7 and molecular formula C₁₉H₄₂ClN, is a mainstream quaternary ammonium cationic surfactant widely traded in the global fine chemical market. For international buyers, formulators and bulk chemical distributors, water solubility is one of the core technical indicators that determines product formulation compatibility, transportation storage and industrial application scenarios. The clear industry conclusion is that cetrimonium chloride is fully water-soluble under normal temperature and conventional industrial concentration conditions.
Different from insoluble non-ionic surfactants and partial soluble oily chemical raw materials, high-purity cetrimonium chloride can be completely dissolved in deionized water and regular tap water without precipitation or layering. It also features excellent solubility in ethanol and isopropyl alcohol, enabling it to adapt to both water-based and alcohol-based formula systems in cross-border industrial production. The product maintains stable solubility within the common industrial temperature range of 5℃ to 60℃ and pH value of 3.0 to 9.0, with no turbidity or separation in diluted aqueous solution.
In international trade transactions, the water solubility advantage of CTAC greatly reduces production and formula costs for downstream manufacturers. Water-soluble characteristics make it easy to dilute, stir and mix in cosmetic processing, textile finishing, daily chemical production and water treatment industries. It is worth noting that cetrimonium chloride is incompatible with high-concentration anionic surfactants. Mixing the two will cause flocculation and failure of active ingredients, which is a key technical note for global bulk purchasers and formula engineers.
Commercial cetrimonium chloride products in the international market are mostly 25% aqueous solution and crystalline powder. The liquid type can be directly miscible with water in any proportion, while the powder type dissolves quickly with simple stirring. As a high-biodegradable, low-irritation and stable water-soluble surfactant, CTAC has always been a hot-selling chemical product in cross-border B2B transactions, widely used in hair conditioners, fabric softeners, industrial emulsifiers and antibacterial agents.
