General description

With formulation challenges in mind, we have used particle engineering technologies to develop functional excipients specifically for solid oral dosage forms. The products in our Parteck® portfolio feature unique particle properties tailored for excellent performance in tableting processes, for specific drug delivery technologies, or for solubility enhancement.
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.


Parteck® COAT excipient is a particle-engineered polyvinyl alcohol (PVA) with a unique structure specifically designed for immediate release film coating application. Due to its optimized particle size, it helps to reduce dissolving times when preparing the coating solution, thus increasing process efficiency. Parteck® COAT excipient can be combined with a variety of supporting excipients such as plasticizers, anti-tacking agents and pigments – all available in our portfolio – to give you full flexibility in designing just the right coating for your need, and in the right timeframe. It is also very well-suited for coating ODT formulations using the Parteck® ODT orally disintegrating excipient system.
The specification of the product is part of the Emprove® Material Qualification Dossier and can be found under "General Properties".
