ORYNOCOAT L 100 - 55

The perfect blend of art and science in coating materials
ORYNOCOAT® L 100–55 is a balanced enteric polymer that dissolves at pH 5.5 and above, enabling early release in the upper small intestine. It ensures robust gastric protection with a quicker release profile compared to other methacrylate copolymers, ideal for APIs requiring rapid onset post-stomach.
  • Early Intestinal Release Dissolves at pH ≥ 5.5, suitable for duodenum-targeted delivery.
  • High Compatibility Works with a wide range of actives and excipients without affecting stability.
  • Proven Performance Offers consistent film formation and reproducible enteric protection.
  • Regulatory Approved Meets global compendial standards (USP/NF, Ph. Eur.).
