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® M excipient achieves excellent compressibility while keeping the APIstable throughout your manufacturing process and beyond. Based on directlycompressible mannitol, it does not require further processing or highcompression forces. The unique and large surface area of Parteck® M excipientenables rapid disintegration and quick release regardless of the dosage. Parteck® M is available in different particle sizes.
The specification of the product is part of the Emprove® Material Qualification Dossier and can be found under "General Properties".
