CAS 505-86-2: Cetyltrimethylammonium hydroxide

Description: Cetyltrimethylammonium hydroxide (CTAC) is a quaternary ammonium compound characterized by its long hydrophobic alkyl chain and a positively charged nitrogen atom. It typically appears as a white to off-white solid or a viscous liquid, depending on its concentration and formulation. CTAC is known for its surfactant properties, making it effective in reducing surface tension and enhancing the solubility of various substances in aqueous solutions. It is commonly used in personal care products, such as shampoos and conditioners, due to its conditioning and emulsifying abilities. Additionally, CTAC exhibits antimicrobial properties, which can contribute to its use as a preservative in cosmetic formulations. The compound is soluble in water and can form micelles, which are aggregates that facilitate the solubilization of oils and other hydrophobic materials. However, it is important to handle CTAC with care, as it can be irritating to the skin and eyes. Overall, its unique properties make it valuable in both industrial and consumer applications.
