Product Insights

The solubilizes & surfactants/emulsifiers segment dominated the market with the largest revenue share of 37.25% in 2025, driven by their critical role in maintaining the stability and performance of complex biopharmaceutical formulations. In an October 2025 industry analysis, polysorbate surfactants, particularly polysorbate 20 and polysorbate 80, were identified as indispensable components in protein therapeutic formulations. These non-ionic surfactants are widely used to stabilize biologics, including monoclonal antibodies, by adsorbing to air-liquid and solid-liquid interfaces during manufacturing, storage, and delivery. This protective mechanism helps prevent protein aggregation, denaturation, particle formation, and loss of potency. However, the analysis also emphasized that polysorbates are susceptible to degradation through oxidation and hydrolysis, making effective control and monitoring essential to ensure long-term product stability and therapeutic efficacy.

The specialty excipients segment is projected to grow at the fastest CAGR of 8.47% over the forecast period, fueled by the increasing complexity of advanced biologics and the need for formulation-specific solutions. Specialty excipients represent a high-value class of excipients engineered to enhance the stability, solubility, and bioavailability of biologic drugs that do not conform to conventional formulation approaches. This category includes co-processed systems and novel stabilizers designed to address challenges such as molecular instability and degradation. According to a 2024 review published in the European Journal of Pharmaceutics and Biopharmaceutics, co-processed excipients, which integrate multiple functional components into a single system, demonstrated superior performance compared to traditional excipients. The review highlighted improved stabilization, enhanced solubility, and stronger protection against degradation in complex biologics, including gene therapies and monoclonal antibodies.

Material Insights

The sugars & polyols segment dominated the market, with the largest revenue share of 35.91% in 2025, due to the rapid expansion of biologics such as monoclonal antibodies, recombinant proteins, vaccines, and peptides. These complex and sensitive molecules are prone to instability during manufacturing, storage, and transportation. Sucrose, trehalose, and mannitol are widely used excipients to maintain structural integrity by reducing protein unfolding, aggregation, and degradation, directly linking their demand to the scale-up of biologics production. For instance, in January 2024, Elsevier published a review in the European Journal of Pharmaceutical Sciences that reported hydration numbers for trehalose ranging from approximately 8.0 to 12.1 compared to sucrose, which ranged from approximately 6.3 to 11.2. It highlighted differences in water interaction and protein stabilization behavior that are critical for biopharmaceutical excipient selection, and noted that trehalose absorbed about 8% (w/w) water after freezing equilibrium, while sucrose absorbed about 4% (w/w), reinforcing why these sugars are preferred stabilizers in biologic formulations, while mannitol was recognized as a widely used polyol excipient alongside these sugars.

The specialty co-processed excipients / novel excipients segment is projected to grow at a CAGR of 8.00% over the forecast period, owing to the increasing limitations of conventional excipient systems in addressing the complex stability challenges of modern biologics. Many advanced biologic drugs exhibit multiple instability mechanisms simultaneously, including sensitivity to shear stress, interfacial exposure, temperature fluctuations, and concentration-related stress. Managing these risks using multiple single-function excipients increases formulation complexity and development risk. Specialty co-processed excipients are engineered to provide integrated functionality within a single system, enabling formulators to address several stability concerns at once while improving efficiency and robustness. For instance, in February 2024, Elsevier B.V., on behalf of KeAi Communications Co. Ltd., published a review titled Co Processed Excipients: Advances and Future Trends, which highlighted enhanced functionality and performance of specialty co-processed excipients. The review reported that liposomal systems ranged from 50 to 1000 nanometers in size, and systems such as Cop AA MCC combined two natural excipients to achieve acceptable bulk density, good flow, and high compatibility, supporting direct compression processes.

Dosage Form Insights

Growth in this segment is further driven by the rising demand for biologic drugs that rely on advanced excipient systems to maintain stability, solubility, and bioavailability. Key excipients include surfactants, stabilizers, tonicity adjusters, and buffering agents. According to a September 2025 review on protein formulation strategies, polysorbate 80 was identified as a widely used non-ionic surfactant for reducing interfacial stress and protein aggregation, while sugars and polyols such as sucrose, trehalose, mannitol, and glycerol were highlighted for improving stability and physiological compatibility in injectable biologics.

The lyophilized (freeze-dried) segment is projected to grow at a CAGR of 4.85% over the forecast period due to the increasing use of freeze-dried formulations for biologic products such as monoclonal antibodies, vaccines, and gene therapies that require enhanced stability. These products are supplied as solid dosage forms that are reconstituted prior to administration, offering improved shelf life and reduced degradation by eliminating water while preserving the structural integrity of active pharmaceutical ingredients. According to a 2025 review on lyophilization technology for injectable pharmaceuticals, lyophilization was described as a low-temperature dehydration process that removes water through sublimation, enabling retention of product quality and extending the shelf life of high-value biologics. This approach also supports easier storage, transportation, and reliable reconstitution, further driving adoption across biopharmaceutical formulations.

Therapeutic Modality Insights

The monoclonal antibodies segment dominated the market with the largest revenue share of 45.64% in 2025, due to their widespread clinical adoption across multiple therapeutic areas and the increasing complexity of their formulations. This trend was reinforced by formulation research and evolving regulatory approvals. For instance, in August 2025, Biophysical Reviews, published by Springer Nature, examined high-concentration monoclonal antibody formulations for subcutaneous administration and highlighted their growing impact on excipient demand. The article reported that, as of 2023, the U.S. Food and Drug Administration had approved 168 monoclonal antibodies, with approximately 43 percent indicated for oncology, about 23 percent for immunologic disorders, nearly 9 percent for neurologic diseases, and around 5 percent each for hematology and respiratory conditions. Infectious diseases, ophthalmology, and gastroenterology each accounted for roughly 3.5 to 4 percent, while cardiology and endocrinology represented about 2 percent each. The review further noted that nearly 60 percent of approved monoclonal antibodies were dosed at 200 mg or higher per administration, 54 percent were manufactured below 50 mg/mL, and high-concentration formulations, defined as 100 to 200 mg/mL injectables, included 45 marketed products, underscoring rising formulation complexity and excipient intensity.

The cell & gene therapy formulations segment is projected to grow at the fastest CAGR of 9.18% over the forecast period due to the transition from small-scale, patient-specific treatments to standardized and repeatable commercial products, which has directly expanded demand within the biopharmaceutical excipients market. Early development programs relied on bespoke formulations, whereas commercialization has required robust and reproducible excipient systems to ensure batch-to-batch consistency and regulatory compliance. Viral vectors and cell-based products are highly sensitive to formulation conditions, positioning excipients as integral elements of process design rather than late-stage additives. For instance, in September 2025, the Social Science Research Network published a study on systematic formulation optimization that evaluated up to 20 excipients across six categories. The study reported adeno-associated virus concentrations above 1×10¹³ viral genomes per mL, melting temperatures above 70 °C, ultrafiltration and diafiltration recovery exceeding 90 percent, and retention of 60 percent infectivity and 87 percent viral particle concentration at 40 °C, underscoring the commercial importance of advanced excipient systems.
