MARKET INSIGHTS
Global Cellulose Acetate Phthalate (CAP) Enteric Coating for Drugs Market size was valued at USD 187.4 million in 2025. The market is projected to grow from USD 196.8 million in 2026 to USD 342.5 million by 2034, exhibiting a CAGR of 6.3% during the forecast period.
Cellulose Acetate Phthalate (CAP) is a widely utilized pharmaceutical excipient specifically designed as an enteric coating material for oral drug formulations. It is a cellulose‑derived polymer that remains stable in acidic gastric environments but dissolves readily in the neutral‑to‑alkaline pH of the small intestine, enabling targeted and controlled drug release. CAP is extensively applied in the coating of tablets, capsules, and granules to protect acid‑sensitive active pharmaceutical ingredients (APIs), minimize gastric irritation, and enhance overall therapeutic efficacy.
The market is experiencing steady growth driven by the rising global demand for controlled‑release drug formulations, increasing prevalence of gastrointestinal disorders, and expanding pharmaceutical manufacturing activities across emerging economies. Furthermore, the growing pipeline of enteric‑coated generic drugs and heightened regulatory emphasis on improved drug bioavailability are reinforcing adoption of CAP‑based coating systems. Key players such as Eastman Chemical Company, Loba Chemie, and Triveni Chemicals operate in this space with established product portfolios catering to pharmaceutical‑grade enteric coating applications worldwide.
