Description

1-Undecylpyridinium is a quaternary ammonium compound (quat) characterized by an undecyl (C11) alkyl chain attached to a pyridinium head group. This structure is valued for its potent cationic surfactant and antimicrobial properties, making it a key functional ingredient in advanced formulations. It is primarily utilized by manufacturers in the biocides, personal care, and industrial cleaning sectors seeking effective and stable active agents.

Application

• Biocide & Disinfectant Formulations: Acts as an active antimicrobial agent in industrial, institutional, and agricultural disinfectants.
• Personal Care Products: Used as a preservative and conditioning agent in hair care and skincare formulations.
• Industrial & Household Cleaners: Provides surfactant and sanitizing properties in hard surface cleaners and detergents.
• Algaecides & Fungicides: Employed in water treatment and material protection to control microbial growth.
• Textile & Leather Processing: Serves as a softener, antistatic agent, and antimicrobial treatment for fibers.
• Phase Transfer Catalyst: Facilitates reactions between reagents in immiscible phases in specialty organic synthesis.
