Defoamers Global Market Report 2025

The defoamers market size has grown steadily in recent years. It will grow from $6.72 billion in 2024 to $6.96 billion in 2025 at a compound annual growth rate (CAGR) of 3.6%. The growth during the historic period can be attributed to the rising demand for water and wastewater treatment, expansion in textile manufacturing, growth in renewable energy projects, a greater role in fermentation-based industries, and the increasing need for water and wastewater treatment.

The defoamers market size is expected to see steady growth in the next few years. It will grow to $7.91 billion in 2029 at a compound annual growth rate (CAGR) of 3.2%. The anticipated growth during the forecast period can be linked to the expansion of industrial wastewater treatment, the growing pulp and paper industry, advancements in the pharmaceutical sector, the development of silicone-free formulations, and the rising demand in the agrochemicals sector. Key trends expected in the forecast period include the adoption of AI-powered foam control systems, integration of smart sensors, the emergence of graphene-enhanced defoamers, self-regulating defoamer technologies, and alignment with Industry 4.0 innovations.

The increasing demand for wastewater treatment is expected to drive the growth of the defoamers market in the coming years. Wastewater treatment involves removing pollutants from wastewater to make it safe for environmental discharge or reuse, typically through physical, chemical, and biological processes. This growing demand is mainly fueled by the rising need for clean water resources, prompted by population growth and escalating environmental concerns that call for sustainable water management practices. Defoamers play a critical role in wastewater treatment by reducing foam formation, thereby enhancing process efficiency and preventing operational issues in equipment like aeration tanks and clarifiers. For example, according to the International Trade Administration, a U.S.-based government agency, Saudi Arabia built 133 wastewater treatment plants in 2021, reflecting a 14.66% increase from the previous year. As a result, the expanding need for wastewater treatment is contributing to the growth of the defoamers market.

Leading companies in the defoamers market are developing advanced products such as siloxane-based defoamers to boost foam control performance in industrial applications. Siloxane-based defoamers, typically composed of silicone compounds like polydimethylsiloxane, are designed to effectively reduce or eliminate foam in various industrial processes. These defoamers act quickly on foam surfaces, causing bubbles to collapse and preventing additional foam formation, thereby enhancing both process efficiency and product quality. For instance, in March 2025, Evonik Industries AG, a chemical manufacturing firm based in Germany, introduced TEGO Foamex 8420 - a new siloxane-based defoamer tailored to tackle tough foaming problems in waterborne overprint varnishes and printing inks. This product adds to Evonik Coating Additives’ extensive defoamer line, offering high-performance defoaming, long-lasting effectiveness, and cost savings due to its low dosage requirement. TEGO Foamex 8420 is especially suitable for formulations with high levels of foam-stabilizing surfactants like diisooctyl sulfosuccinate (DOSS) and for challenging pigment dispersions, both of which are known for their foaming difficulties.

In June 2022, Italmatch Chemicals S.p.A., a chemical manufacturing company based in Italy, acquired Aubin Group for an undisclosed sum. Through this acquisition, Italmatch Chemicals aims to strengthen its presence in the oil and gas, renewable energy, and Middle East markets, while also expanding its product lineup with environmentally sustainable solutions aligned with its ESG (Environmental, Social, and Governance) strategy. Aubin Limited, based in the UK, specializes in the production of chemical solutions, including defoamers.

Defoamers, or anti-foaming agents, are chemical compounds utilized to minimize or inhibit foam formation in industrial liquids and processes. They function by breaking down the foam’s structure, causing the bubbles to collapse and thus preventing additional foam from developing. Generally, defoamers are not soluble in the foaming liquid and work by reducing the surface tension between the foam and the liquid.

The primary types of defoamers include water-based, oil-based, silicone-based, and others. Water-based defoamers utilize water as the main carrier or continuous phase and consist of emulsified active agents dispersed in water, specifically formulated to manage or eliminate foam in water-based systems. These defoamers are used in both aqueous and non-aqueous or solvent-based mediums. Their applications span across several industries including pulp and paper paints, coatings, and inks adhesives and sealants agriculture personal care and cosmetics food and beverages;household and industrial or institutional cleaning water treatment, and more.
