Our market reports now include the latest updates on global tariffs, trade impacts, and evolving supply chain dynamics.

How Big Is the Defoamers Market Size Expected to Be by 2034?
In the last few years, there has been a consistent growth in the size of the defoamers market. It is projected to expand from $6.72 billion in 2024 to $6.96 billion in 2025, maintaining a compound annual growth rate (CAGR) of 3.6%. This upward trajectory in the historical period can be credited to the amplified demand in amongst water and wastewater treatment sectors, growth in textile production, burgeoning renewable energy initiatives, its augmented role in fermentation-based industries as well as the increasing necessity in water and wastewater treatment.

In the following years, the defoamers market's size will experience a stable increase, reaching $7.91 billion in 2029, with a compound annual growth rate (CAGR) of 3.2%. This growth during the forecast period is primarily due to the expansion of industrial wastewater treatment, the surge in the pulp and paper sector, the progression of the pharmaceutical industry, silicone-free formulations, and the rise in the agrochemicals sector. In the forecast period, significant trends will be AI-powered foam control systems, the incorporation of smart sensors, graphene-introduced defoamers, self-adjusting defoamer systems, and assimilation with industry 4.0 technologies.

What Long-Term Drivers Are Shaping Defoamers Market Trends?
The growth of the defoamers market is projected to be driven by an increase in the need for wastewater treatment. Typically accomplished via physical, chemical, and biological methods, wastewater treatment targets the removal of harmful contaminants from wastewater so that it is safe for reuse or environmental discharge. A surge in the demand for wastewater treatment primarily stems from the escalating requirement for clean water resources, propelled by burgeoning populations and escalating environmental apprehensions, thereby necessitating sustainable water management techniques. Defoamers play a crucial role in wastewater treatment due to their capacity to curtail foam formation, thus enhancing process efficiency and forestalling issues in equipment like aeration tanks and clarifiers. For example, the International Trade Administration, a government agency in the US reported in January 2024 that Saudi Arabia built 133 wastewater treatment facilities in 2021, which represents a 14.66% increase from the preceding year. Consequently, the burgeoning demand for wastewater treatment is fuelling the expansion of the defoamers market.

Who Are the Top Competitors in Key Defoamers Market Segments?
Major companies operating in the defoamers market are BASF SE, Dow Inc., Shin-Etsu Chemical Co. Ltd., Evonik Industries AG, Solvay S.A., Air Products and Chemicals Inc., CHT Group, Wacker Chemie AG, The Lubrizol Corporation, Clariant AG, Kemira Oyj, Croda International Plc, Ashland Inc., Elementis PLC, Hydrite Chemical Co., Synalloy Chemicals, Münzing Chemie GmbH, SAN NOPCO LIMITED, PMC Ouvrie, Momentive Performance Materials Inc., Sauradip Chemical Industries Pvt. Ltd.

What Defoamers Market Trends Are Gaining Traction Across Different Segments?
The key players in the defoamers market are concentrating on creating innovative products like siloxane-based defoamers which are designed to improve foam control effectiveness and performance in various industries. An antifoaming agent made with silicone compounds, primarily polydimethylsiloxane, a siloxane-based defoamer is engineered to limit or eradicate foam in industrial procedures. It enhances process efficiency and product quality by swiftly covering foam surfaces, making bubbles collapse, and inhibiting foam creation. For example, a chemical manufacturing company based in Germany, Evonik Industries AG, introduced TEGO Foamex 8420 in March 2025. This is a novel, siloxane-based defoamer created to tackle intense foaming issues in waterborne overprint varnishes and printing ink. This addition to the wide-ranging portfolio of defoamers by Evonik Coating Additives provides superior defoaming performance, longevity, and cost-effectiveness due to minimal dosage necessities. Tego Foamex 8420 notably works well in formulations that contain high quantities of foam-stabilizing surfactants like diisooctyl sulfosuccinate (DOSS) and intricate pigment grinds, both known to be challenging to defoam.
