Boron in pharmaceuticals
Each year in the U.S. alone, more than 100 million people use eye drops and eye wash to seek relief from discomfort.
With so many people relying on these products to keep their vision healthy, you shoulder tremendous responsibility for producing safe and effective solutions. Boron is often key to achieving these properties. When applied in small quantities, boric acid retains moisture, controls pH, and provides relief from irritants.
As with any pharmaceutical application, the partner you source raw materials from is not a choice to be taken lightly. Leading eyecare product manufacturers and distributors trust U.S. Borax to deliver high-quality borates with exceptional purity to meet requirements in the tightly regulated pharmaceutical industry.
Our exceptional compliance record starts at our Coudekerque operations, where our refined borates are subject to an additional refining process to ensure low levels of elemental impurities.

Why is boron used in eye drops and other eye care products?
Using a carefully administered, pharmaceutical grade of boric acid in eye drops and eye-care products is not new. Borates have been key ingredients in eye-care for generations, because of three main benefits they impart:
Mild antibiotic properties
Buffering properties
Compatible tonicity
