In the realm of ocular health, the formulation of eye drops and contact lens solutions demands careful selection of ingredients to ensure both efficacy and safety. Polyquaternium-1 (PQ-1), identified by its CAS number 75345-27-6, stands out as a critical component, primarily serving as an advanced preservative. Its unique properties make it an indispensable ingredient for manufacturers committed to developing high-quality ocular care products. As a leading manufacturer and supplier of this vital chemical, we are pleased to provide insights into its applications and benefits.

Polyquaternium-1 is a synthetic polymer that has garnered significant attention for its role as a bacteriostatic agent. Unlike older preservatives that can be harsh on the delicate tissues of the eye, PQ-1 offers a more biocompatible profile. This makes it ideal for use in a wide range of ophthalmic applications, including glaucoma medications, artificial tears, and solutions designed for contact lens care. The primary advantage of PQ-1 lies in its ability to effectively inhibit microbial growth while minimizing ocular surface toxicity. This is a crucial consideration for products that come into direct and prolonged contact with the eye.

The chemical structure of Polyquaternium-1, a large polymeric quaternary ammonium compound, differentiates it from smaller, more penetrative molecules like Benzalkonium Chloride (BAK). This larger size limits its ability to penetrate corneal and conjunctival cells, thereby reducing the risk of irritation, inflammation, and other adverse effects often associated with BAK. For companies seeking to buy Polyquaternium-1, this improved safety profile translates into enhanced product acceptance and patient compliance. We are proud to be a reliable source for this essential pharmaceutical intermediate, offering competitive pricing for our esteemed clients.

The application of Polyquaternium-1 extends beyond just preservation. It also contributes to the rheological properties of solutions, acting as a thickening agent that can improve product stability and the overall user experience. In contact lens solutions, it aids in maintaining the cleanliness and comfort of lenses. For pharmaceutical formulators, the consistent quality and availability of PQ-1 are paramount. As a dedicated supplier, we ensure that our Polyquaternium-1 meets the highest purity standards, making it suitable for pharmaceutical manufacturing. Our wholesale options make it accessible for large-scale production needs.

In conclusion, Polyquaternium-1 (CAS 75345-27-6) is a cornerstone ingredient for modern ophthalmic product development. Its blend of effective preservation and superior ocular compatibility makes it a preferred choice for formulators worldwide.
