Different Grades and Blends of Propylene Glycol

Propylene glycol is an ingredient found typically in hair products and other personal care goods. But did you know that it is versatile for industrial and commercial applications, too. Propylene glycol is relatively cost effective, making it suitable for a wide variety of purposes and manufacturing requirements. The chemical comes in different blends and grades, as well as delivery methods to meet every unique need. Reputable suppliers of propylene glycol can provide the blend of dye, inhibitor, or water that you need in any conventional storage medium or vessel like totes, bulk, pail, or drums.

USP/EP is pharmaceutical grade propylene glycol that is very pure at 99.5 to 99.9 percent. Some suppliers repackage it in smaller containers for low-volume applications that require high-grade propylene glycol, but without the final packaging that is common to USP requirements. It comes in a USP kosher option, too, which is suitable for medicine, food, and beverage manufacturing that require kosher or USP certification.

The chemical is a known deicer and can be used to prevent or remove the formation of ice, frost, or snow in water systems. Corrosion inhibited propylene glycol (95 percent) is suitable for water process applications that have copper, iron, low grade stainless steel, and other similar metals that require protection from corrosion or rusting. It is relatively safe to use as long as it is not administered in water systems where possible contact with food and potable water is possible. Another type of 95 percent corrosion inhibited propylene glycol is the USP grade, which is safe to use in water systems that are linked to potable water or food supplies.

The economical way to buy propylene glycol is in concentrated form, but be sure to get in touch with the supplier to learn more about the product and how it can be stored. This way, you can purchase the right volume and blend of USP propylene glycol for various applications.
