Propylene Glycol — CAS 57-55-6

Propylene glycol (PG, CAS 57-55-6) is a widely used synthetic diol and a versatile raw material across food, pharmaceutical, personal care, and industrial sectors. UAB An Group Export supplies it in USP/food grade and industrial grade, matched to each customer's process and application requirements.

It is used across food and beverage production, pharmaceutical formulations, personal care and cosmetic products, industrial antifreeze and heat transfer fluids, and chemical manufacturing. Its low toxicity, hygroscopic properties, and broad solubility profile make it one of the most widely used functional ingredients and process chemicals across consumer and industrial applications.

For industrial buyers, supply is coordinated around grade, purity, volume, packaging, and delivery destination, in line with applicable product and transport regulations. Bulk and commercial orders are both handled — send your requirements and we'll prepare a quote covering supply, packaging, logistics, and delivery.
