General description

To address challenges of solid formulation manufacturing, we have developed a comprehensive product portfolio to meet with your solid dosage needs in mind. Although solid dose formulations are one of the the most established dosage forms in the pharmaceutical market, the complexity of manufacturing final drug products is becoming more and more challenging. API stability, release kinetics and bioavailability limitations, such as low API solubility, are just a few of many critical obstacles on the way to the market.
As part of our Emprove® Program, our raw materials are offered with extensive documentation facilitating compliance of your pharma and biopharma product, full supply chain transparency and risk mitigation. Our SAFC® portfolio of high-quality products for biopharmaceutical and pharmaceutical formulation and production withstands strict quality control procedures and is produced according to applicable cGMP guidelines.
