Global Defoamers Market - Forecasts from 2025 to 2030

The global defoamers market is expected to grow at a CAGR of 5.1%, reaching a market size of US$4.949 billion in 2030 from US$3.859 billion in 2025.
A defoamer or an anti-foaming agent is a chemical additive that reduces and prevents the formation of foam in industrial process liquids. Foam is undesirable in most industrial processes and causes a lot of problems in operations, such as defective coatings on the surface, blocking oxygen transfer, and preventing the filling of containers or tanks up to capacity. A defoamer eliminates existing foam, while anti-foam prevents further formation of foam.
Defoamers are used in many industrial processes and products such as agrochemicals, water treatment, paper and pulp, paints and coatings, food processing, oil and gas, pharmaceuticals, chemicals, metalworking, etc. The application of defoamers benefits these processes through increased production capacity, output volume, and reduced operational cost. They also play an important role in reducing the carbon footprint caused by the manufacturing process of end-users, driving the demand for low VOC solvent-free defoamers.
Manufacturers prioritize utilizing bio-based and sustainable raw materials rather than petro-based variants, while the producers focus on developing innovative and high-performance silicone compounds to improve product performance. Companies are aiming for their market footprints through new product launches, product portfolio expansion, geographical expansions, and investments in research and development. They are focusing on developing products designed for specific applications. To strengthen their market positions, they are also planning to expand their customer base in various industries and focus on product development to meet varying customer needs.
Rising environmental awareness among consumers in developed regions is further anticipated to propel the use of water-based defoamers due to their environmental sustainability. In this regard, in June 2024, Elementis announced their new 96% biobased carbon content, C14 verified DAPRO BIO 9910, which is more sustainable. The company is regarded as a leading specialty chemical supplier of rheology modifiers for paint, coating & industrial aqueous applications. This key development will allow the company to meet the growing demand of customers for environmentally safe and cost-effective defoamers.
However, silicone defoamers contain volatile organic compound (VOC) content. High VOC content is dangerous to the environment. Therefore, companies are focusing on manufacturing VOC content-free products and innovating to develop high-performance silicone compounds as raw materials. However, some companies are still producing old silicone defoamers that might emit dangerous gases that are harmful to the environment and human health.
Regulatory bodies like the U.S. FDA and the European Commission have also enforced several laws to manage the composition of defoamers. Environmental regulations worldwide encourage their use over high-VOC deformers because of the low VOC of solvent-free deformers.
Global defoamers market drivers

Rising demand from the End-User Industries
Deformers are very important chemicals used in almost every major industry, such as paper and pulp, oil and gas, water treatment, etc. For example, in the oil & gas industry, when an oil well is drilled, drilling fluid is used to balance the borehole. At times, drilling fluid generates foam as it reaches the surface, and at this stage, foam can be difficult to pump and clean up. Hence, defoamers are added to the fluid to break the foam. It is a necessary chemical that will be consumed more with the expansion of end-user industries.
Another example is the use of defoamers in water treatment facilities by municipal and industrial wastewater streams. Where they assist in reducing pump cavitations, preventing loss due to overflow, and improving sanitation and safety. Hence, defoamers optimize the sludge dewatering process and facilitate clarification, filtration, thickening, and floatation processes.
Geographical outlook of the global defoamers market

The Asia Pacific region will dominate the global defoamers market during the forecast period.
The major economies like China, Japan, India, and South Korea dominate the Asia-Pacific region. Some of the fastest-growing emerging economies are from this region, such as ASEAN countries.
The APAC market for defoamers is growing owing to several factors, such as rapid industrialization, especially in China and India, where there are strong manufacturing activities and increasing investment in infrastructures. The increasing production of consumer goods, especially in the food and beverage sector, and stringent environmental regulations promoting effective waste management further fuel the demand for defoaming agents. Additionally, the rise in applications across diverse industries, such as paints and coatings, agrochemicals, and water treatment, underscores the critical role of defoamers in optimizing production processes and enhancing product quality within this dynamic market landscape.
