Polyquaternium-1 (PQ-1) is a versatile cationic polymer with a unique set of chemical properties that make it valuable across various industries, most notably in pharmaceuticals and personal care. While its application as an ophthalmic preservative in eye drops and contact lens solutions is widely recognized, its utility extends further, making it a sought-after ingredient for formulators seeking effective and safe compounds. As a dedicated manufacturer and supplier, we aim to provide comprehensive insights into the capabilities of Polyquaternium-1.

Chemically, Polyquaternium-1 is a polymeric quaternary ammonium compound characterized by its large molecular size and positive charge. This cationic nature contributes to its efficacy as an antimicrobial agent by interacting with and disrupting the cell membranes of bacteria and fungi. Unlike smaller cationic molecules, PQ-1's polymeric structure limits its ability to readily penetrate biological membranes, including those of human cells. This characteristic is the foundation for its favorable safety profile and reduced ocular surface toxicity compared to many other preservatives, a key factor in its widespread adoption in ophthalmic formulations.

The applications of Polyquaternium-1 are diverse, stemming from its dual functionality as both a preservative and a conditioning agent. In ophthalmic products, as mentioned, it ensures sterility and enhances wearer comfort. Beyond eye care, PQ-1 is utilized in cosmetic and personal care products such as shampoos, conditioners, and lotions. Here, it acts as an antimicrobial agent to preserve the product and as a conditioning agent that can improve hair and skin feel, manage static electricity, and enhance product adherence. Its ability to form a thin film on surfaces can also contribute to a smooth finish.

For pharmaceutical manufacturers, understanding the chemical properties of PQ-1 is essential for effective formulation. Its water solubility and stability in various formulations make it an adaptable ingredient. We supply Polyquaternium-1 in high-purity grades, ensuring that it meets the rigorous standards required for pharmaceutical and cosmetic applications.
