Defoamers Market Report 2026

The defoamers market size has grown steadily in recent years. It will grow from $6.87 billion in 2025 to $7.07 billion in 2026 at a compound annual growth rate (CAGR) of 2.9%. The growth in the historic period can be attributed to industrial process optimization needs, expansion of pulp and paper industry, growth of chemical manufacturing, demand for process efficiency, availability of silicone chemistry.

The defoamers market size is expected to see steady growth in the next few years. It will grow to $7.92 billion in 2030 at a compound annual growth rate (CAGR) of 2.9%. The growth in the forecast period can be attributed to growth of wastewater treatment facilities, expansion of industrial cleaning, demand for eco friendly defoamers, innovation in hybrid defoamer formulations, rising food processing activities. Major trends in the forecast period include growing use in water treatment processes, rising demand from paints and coatings industry, expansion of food and beverage applications, increasing preference for silicone based defoamers, focus on low dosage high efficiency products.

The increasing demand for wastewater treatment is expected to drive the growth of the defoamers market in the coming years. Wastewater treatment involves removing contaminants from wastewater to make it safe for environmental discharge or reuse, typically through physical, chemical, and biological methods. This rising demand is primarily driven by the need for clean water resources, as growing populations and heightened environmental concerns necessitate sustainable water management practices. Defoamers play a critical role in wastewater treatment by minimizing foam formation, improving process efficiency, and preventing operational issues in equipment such as aeration tanks and clarifiers. For example, in October 2024, the US Environmental Protection Agency (EPA) reported that the US received $6.2 billion in investments for Fiscal Year 2025 to upgrade water infrastructure, combining a new $3.6 billion allocation with an earlier $2.6 billion, to help manage wastewater safely, protect freshwater resources, and deliver safe drinking water to homes, schools, and businesses. Therefore, the rising demand for wastewater treatment is driving the defoamers market.

Leading companies in the defoamers market are focusing on developing innovative products such as siloxane-based defoamers to improve foam control efficiency and performance in industrial applications. Siloxane-based defoamers, made from silicone compounds like polydimethylsiloxane, reduce or eliminate foam by spreading quickly over foam surfaces, collapsing bubbles, and preventing further foam formation, thereby enhancing process efficiency and product quality. For instance, in March 2025, Evonik Industries AG, a Germany-based chemical manufacturer, launched TEGO Foamex 8420, a next-generation siloxane-based defoamer designed to tackle challenging foaming issues in waterborne overprint varnishes and printing inks. This product expands Evonik Coating Additives’ portfolio of defoamers, offering superior performance, long-term effectiveness, and cost efficiency through low dosage requirements. TEGO Foamex 8420 is particularly effective in formulations containing high levels of foam-stabilizing surfactants such as diisooctyl sulfosuccinate (DOSS) and in complex pigment grinds, both of which are traditionally difficult to defoam.

In February 2025, PennWhite India Private Limited, an India-based specialty chemicals provider, acquired the defoamer business of Sicagen India Limited for an undisclosed sum. Through this acquisition, PennWhite aims to strengthen its presence in the Indian defoamer market, expand its customer base, and leverage Sicagen’s existing portfolio to accelerate growth in specialty chemicals for industrial applications. Sicagen India Limited is an India-based specialty chemicals company offering defoamer solutions.
