Chemical Profile

Product Overview

Propylene Glycol 60% USP Grade is a higher-strength pre-diluted solution produced from USP-grade propylene glycol and deionized water for applications that require both a stronger glycol concentration and a higher-purity feedstock profile. It is intended for operations that need reliable concentration control without the variability of on-site mixing. Manufactured to USP-NF monograph standards, this product is suitable for pharmaceutical, food processing, and cosmetic applications requiring documented purity.

This 60% solution is commonly selected for lower-temperature heat-transfer duties, sensitive formulation processes, and equipment support applications where low toxicity, cleaner raw material standards, and consistent batch quality are important. It combines the practical handling benefits of a ready-to-use solution with the commercial flexibility of multiple package sizes.
