Propylene Glycol (CAS 57-55-6), or 1,2-Propanediol, is a linchpin ingredient in the pharmaceutical and cosmetic industries, prized for its purity, safety, and functional efficacy. For procurement managers and formulation scientists, sourcing high-quality Propylene Glycol is not just about meeting specifications but ensuring the integrity and safety of the final product.

In the pharmaceutical realm, Propylene Glycol is a widely used excipient, acting as a solvent, co-solvent, and stabilizer in a vast array of preparations. Its ability to dissolve poorly water-soluble active pharmaceutical ingredients (APIs) is critical for developing effective oral, injectable, and topical medications. As a humectant, it helps maintain the moisture content of topical formulations, enhancing skin feel and product stability. Pharmaceutical grade Propylene Glycol adheres to stringent USP/NF monograph requirements, guaranteeing its suitability for human use. Buyers seeking to purchase this essential ingredient should always prioritize suppliers that can provide comprehensive Certificates of Analysis.

The cosmetic and personal care industry also relies heavily on Propylene Glycol for its humectant, emollient, and solvent properties. It's found in moisturizers, lotions, shampoos, and makeup, where it helps retain moisture, improve texture, and enhance the delivery of other active ingredients. Its skin-friendly nature, when used within recommended concentrations, makes it a popular choice for sensitive skin formulations. For manufacturers, securing a consistent supply of cosmetic grade Propylene Glycol from a reputable manufacturer is key to maintaining product quality and brand trust.
