Description

General description

When working on a pharmaceutical formulation, there are specific considerations to make and challenging hurdles to take before you can successfully launch your final drug product - formulation stability, release kinetics and bioavailability limitations just to name a few. With our application know-how and regulatory expertise, we support you in every step of development, scale-up, and production.
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.

Application

Polyethylene glycol (PEG) is a multipurpose polymer which can be applied in solid, semi-solid and liquid formulations. Its broad functional spectrum includes e.g. improvement of API solubility, acting as a lubricant for tablet coating, function as a carrier, and many more. Our comprehensive portfolio of PEGs comprises diverse polymer sizes of different molecular weights to meet your specific application and needs.
