Market Drivers
1. Rising Demand for Pharmaceutical Excipients
The pharmaceutical industry’s shift towards complex formulations necessitates novel excipients. Adipic acid’s role in stabilizing drug delivery systems, especially in controlled-release formulations, fosters its resurgence as an excipient. The global pharmaceutical excipients market size, valued at approximately $7.4 billion in 2021, is projected to expand at a CAGR of 6-7% [2], indirectly supporting adipic acid's growth as a key component.
2. Advancements in Bio-based Production Methods
In alignment with sustainability initiatives, bio-based adipic acid production is gaining traction. Unlike traditional phenol-based oxidation, bio-processes utilize fermentative pathways, reducing environmental impact. This shift can lower costs and appeal to ISO-certified pharmaceutical manufacturers requiring eco-friendly inputs, thus expanding adipic acid’s market share in pharmaceutical manufacturing.
3. Increasing Regulatory Focus on Material Purity
Pharmaceutical excipients demand high purity standards, mandating rigorous quality controls. The ability of bio-based or improved synthetic routes to produce adipic acid with minimal contaminants enhances its attractiveness. Conformance to pharmacopeial standards (e.g., USP, EP) supports market expansion.
4. Growing Pharmaceutical Market in Emerging Economies
APAC countries, especially China and India, exhibit robust pharmaceutical manufacturing growth, increasing demand for raw materials like adipic acid. The region’s expanding API production facilities and excipient manufacturing capacities create a fertile environment for adipic acid’s long-term prospects.
Challenges Impacting the Market
1. Environmental Concerns and Regulatory Constraints
Traditional adipic acid production involves nitric acid-based oxidation, generating nitrous oxide—a potent greenhouse gas. Regulatory pressures to reduce emissions threaten the sustainability of existing manufacturing processes. Transitioning to bio-based or cleaner synthetic methods entails initial capital expenditure and technological hurdles, which may temporarily suppress supply.
2. Competitive Manufacturing Landscape
Major producers, such as Invista, BASF, and Eastman Chemical, enjoy economies of scale and established distribution networks. This oligopolistic landscape presents entry barriers for new entrants seeking to produce pharmaceutical-grade adipic acid, constraining supply diversification.
3. Cost Volatility of Raw Materials
Raw material prices, particularly benzene and cyclohexanol, fluctuate due to geopolitical and market dynamics. Such volatility affects manufacturing costs, impacting pricing strategies within pharmaceutical excipient supply chains.
Financial Trajectory and Forecast

Pricing strategies for pharmaceutical-grade adipic acid will likely stabilize as supply chains diversify and bio-based methods advance.
Competitive Landscape
Major players in the adipic acid market are investing heavily in sustainable production technologies and capacity expansion. Eastman Chemical announced plans to build a bio-based adipic acid plant, aiming to produce 100,000 metric tons annually by 2027 [4]. This initiative aligns with global environmental targets and promises to stabilize supply while reducing carbon footprint.
Regional producers in China and India are expanding capacities to meet the increasing Asian demand, often with lower-cost bio-processes, providing pricing pressure and increased market access for pharmaceutical manufacturers.
Regulatory and Sustainability Outlook
The transition toward greener production methods aligns with global environmental goals, influencing regulatory frameworks. The European Chemical Agency (ECHA) and the U.S. EPA are implementing stricter emissions controls, incentivizing the adoption of bio-based adipic acid. Pharmaceutical companies are increasingly prioritizing excipients that meet environmental, social, and governance (ESG) standards, further accelerating adaptation.
Conclusion
Adipic acid’s pathway in pharmaceutical excipients reflects a confluence of technological innovation, regulatory evolution, and market expansion. The ongoing shift toward sustainable, high-purity production routes positions adipic acid favorably within the pharmaceutical supply chain. Its financial trajectory remains positive, buoyed by the burgeoning pharmaceutical markets and proactive industry investments. Nevertheless, supply chain adjustments, environmental regulations, and raw material volatility will necessitate continuous strategic adaptations.
