100% Tartaric Acid Pellets are inert cores made following Good Manufacturing Practices
for bulk pharmaceutical excipients


Inert Microgranules made of pharmaceutical grade, 100% natural tartaric acid

Tartaric acid is useful in pellets form as inert core for the manufacturing of Pharmaceutical Ingredients in order to improve the solubility of weakly basic drugs.


Project Design

  • Surface: roughness and sphericity to ensure uniform application; no porosity, cracks or holes;
  • Reproducibility: Reliable and reproducible uniformity for batch-to-batch consistency;
  • Different Particle sizes: for different pharmaceutical dosages;
  • Minimum humidity content;
  • Low friability and hardness to withstand fluid bed processing;
