In pharmaceutical applications as excipients Dow PuraGuard™ Propylene Glycol USP/EP offers one of the highest purity propylene glycols available in the marketplace with a specified purity of 99.8 percent or greater.

By offering significantly lower moisture vapor transmission rates (MVTR) than conventional blow molding materials, the advanced high density polyethylene (HDPE) can create excellent opportunities for extended shelf life. Likewise, the resin's inherent stiffness and toughness allow it to offer improved bottle rigidity/strength performance balance and exceptional environmental stress crack resistance. This also creates the potential for up to 30 percent lighter bottle weights - and corresponding reductions in the use of virgin plastic.

There is an increasing preference for skin delivery remedies that can be self-applied at home. Formulators must strive to deliver active ingredients through an exceptional sensory experience to patients of all ages. CARBOWAX™️ SENTRY™️ Polyethylene Glycols (PEGs) have a long history of use in topical applications because they meet all compendial requirements.

This session was originally broadcast as part of the CPHI Worldwide 2021 digital content programme. One of the top priorities of pharmaceutical companies in bringing new products to market is to prove a drug substance is safe and effective against a certain illness. As you would expect, especially in the beginning stages of development, companies primarily focus on the API itself and not necessarily the excipients that will go into the final drug product. Instead, compendial requirements and guidelines such as those from ICH exist to ensure excipient quality and safety. Not only this is important from a regulatory perspective, but excipient quality can also impact product performance, even if those excipients meet all compendial requirements. In this session, you will learn about: Recent regulatory developments relating to residual impurities in pharmaceutical excipients Challenges in analytical methods to meet increasingly stringent targets How you can work with your excipient supplier to ensure high product quality
