General description

With formulation challenges in mind, we have used particle engineering technologies to develop functional excipients specifically for solid 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.

Application

Due to regulatory developments, there is an increasing interest in titanium dioxide-free solutions for the coloring of solid dosage forms. Parteck® TA - our titanium dioxide alternative - is a mineral and nature-identical pigment specifically developed for the use in tablet film coatings. It helps to achieve a level of covering and whiteness comparable to titanium dioxide film coatings without affecting your tablets’ performance. The enhanced opacity is ensured by its unique morphology and designed particle size distribution

Features and Benefits

  • A mineral, nature-identical pigment
  • Excellent compatibility with HPMC and PVA film coatings (including our PARTECK® COAT excipient)
  • High process efficiency due to lower viscosity of spraying liquids
  • Enables an appealing and uniform tablet appearance
  • Enhanced opacity due to tailored particle size distribution and unique morphology
