Overview
Polyquaternium-1 + myristamidopropyl dimethylamine is a dual-disinfectant combination used primarily as a preservative and antimicrobial system in ophthalmic products, especially in multi-purpose contact lens cleaning and disinfecting solutions. Polyquaternium-1 (Polyquad) is a polymeric quaternary ammonium compound that serves as a broad-spectrum antimicrobial and preservative, while myristamidopropyl dimethylamine (Aldox) is an amidoamine disinfectant that enhances efficacy, particularly against fungi and certain bacteria. Together, these agents inactivate microorganisms by disrupting their cellular membranes. The combination is most notably present in products like OPTI-FREE PureMoist, designed to provide effective disinfection and comfort for contact lens users.
