Global demand for defoamers stood at 2,550 kilo tons in 2014 and is anticipated to reach 3,550  kilo tons in 2023, increasing at a CAGR of 3.8% from 2015 to 2023. In terms of revenue, the  defoamers market was valued at US$ 2,764 Mn in 2014 and is projected to reach US$ 4,107.5  Mn in 2023, expanding at a CAGR of 4.5% from 2015 to 2023.The global defoamers market is primarily driven by increasing demand for defoamers in pulp and  paper, water treatment, and paints and coatings industries. However, factors such as regulatory  issues are hampering market growth. Currently, alternative manufacturers focus on product  innovation and customized solutions to increase their market share. Furthermore, growth in the  emerging economies is expected to act as an opportunity for the defoamers market in the next  nine years.

Silicone-based defoamers was the largest product segment of the global defoamers market in  2014, accounting for 44.6% share in 2014. Water-based defoamers is anticipated to be the  fastest-growing product segment of the defoamers market, expanding at a CAGR of 4.1% from  2015 to 2023. Rising demand for defoamers in pulp and paper, paints and coatings, and water  treatment industries is likely to drive the global defoamers market in the next few years. Pulp and paper was the largest application segment of the global defoamers market in 2014,  holding 31.3% share in 2014. Water treatment is estimated to be the fastest-growing application  segment of the defoamers market, expanding at a CAGR of 4.0% from 2015 to 2023. The global market for defoamers is highly fragmented in nature. The top five companies account  for 18% share of the market in 2014. Key players in the defoamers market include Dow Corning  Corporation, Ashland, Inc., Evonik Industries AG, Air Products and Chemicals, Inc., and Bluestar  Silicones.

Foam, a bubbly liquid, is often produced as an unwanted by-product during the manufacture of  various substances. Foam poses difficulties to various industries such as chemicals, especially  during the biochemical process. It hampers the flow of liquid and blocks transfer of oxygen from  air. Therefore, antifoaming agents (defoamers) such as silicone oils are added to prevent the  problem of foaming. Usage of chemical methods to control foam are not always preferred,  especially in food and pharmaceutical industries, where the product quality is of vital importance.  Mechanical methods are mostly preferred over chemical methods to prevent the formation of foam  in these industries. Defoamers or antifoaming agents are chemical additives that reduce and hamper the formation of foam in industrial process. Defoamers are generally insoluble in the foaming medium and  possess surface active properties. These offer low viscosity and spread rapidly on the foamy  surface. This is one of the essential characteristics of defoamers. Defoamers have affinity to the  air-liquid surface, where these threaten the foam lamellas. This results in rupture of air bubbles  and breakdown of the surface foam.
