Pharmaceutical formulators continue to strive to create market leading products with maximum efficacy, quality, and performance. However, the inability to achieve a high level of API solubility and stability are common day-to-day challenges which limit product success. With the help from Croda’s superior quality and high purity line of specialty excipients, formulators are able to surpass these barriers, making Croda the supplier of choice in the global pharmaceutical market. With products being manufactured at multiple sites throughout the world, we are able to provide a consistent, local supply of a vast range of high purity surfactants, lipids, and other chemical specialties.

Croda also provides a large span of products for topical dosage forms, as well as multi-compendial solvents, and surfactants suitable for parenteral, oral, ophthalmic, nasal, vaginal, and suppository formulations to help formulators maximize the value of their final drug product.

Croda has developed a proprietary process called Super RefiningTM to help create products of superior quality and purity. The process helps to physically remove impurities from pharmaceutical excipients and nutritional oils without altering their fundamental structure. In addition, Croda has been actively investing in GMP API technologies and R&D to ensure the continual delivery of exceptional ingredients, including expertise in drug delivery and vaccine adjuvants. We consider future health and wellness needs when creating new specialty products.
