Stearyltrimethylammonium chloride

Description:
Stearyltrimethylammonium chloride, with the CAS number 112-03-8, is a quaternary ammonium compound characterized by its long hydrophobic stearyl chain and three methyl groups attached to a nitrogen atom. This structure imparts both hydrophobic and hydrophilic properties, making it a cationic surfactant. It typically appears as a white to off-white solid or a viscous liquid, depending on the temperature. Stearyltrimethylammonium chloride is soluble in water and organic solvents, which enhances its utility in various applications. It is commonly used in personal care products, such as conditioners and creams, due to its ability to improve texture and provide antimicrobial properties. Additionally, it serves as an emulsifying agent in formulations, helping to stabilize mixtures of oil and water. Its cationic nature allows it to interact effectively with negatively charged surfaces, such as hair and skin, promoting conditioning effects. However, it is essential to handle this compound with care, as it can be irritating to the skin and eyes in concentrated forms.
