Non-silicone
defoamers are gaining traction in biotechnology, detergents, and anaerobic
wastewater treatment due to their improved shelf life, rapid dispersion, and
lower active loss. In 2025, Shin-Etsu Chemical partnered with an Indian
microbial fermentation firm to localize antifoam production in southern India,
aiming to reduce lead times and meet growing demand. Despite concerns over
residue and biodegradability, intensified R&D is driving efforts to meet OECD
301 standards. The global defoamers market is expected to remain robust through
2035, supported by regulatory compliance, advanced formulations, and targeted
sector innovation.

Silicone-Based
Defoamers Dominate with Superior Industrial Versatility
Silicone-based defoamers lead the global market due to their
exceptional performance in high-temperature and chemically intensive
environments. Their compatibility with both water- and solvent-based systems
makes them ideal for applications in pulp & paper, paints & coatings,
and water treatment. Innovations in emulsification and silicon polymer
technology are further enhancing dispersion, efficiency, and long-term
stability.
Oil-Based Defoamers
Gain Ground in Construction and Coatings
Oil-based defoamers, derived from mineral or vegetable oils,
are becoming increasingly popular in paints, adhesives, and construction
materials. Their cost-effectiveness and compatibility with hydrophobic systems
make them suitable for concrete, latex paints, and sealants, especially as
global infrastructure and urbanization continue to expand.
Water Treatment
Sector Drives Demand for Biodegradable Defoamers
The water and wastewater treatment industry is a key
consumer of defoamers due to regulatory pressures to control foam and ensure
efficient filtration. Silicone and polymer-based biodegradable defoamers are
preferred for their low toxicity and high foam knockdown, aligning with
environmental sustainability goals and stricter discharge regulations.
Pulp & Paper
Industry Strengthens Adoption for Enhanced Efficiency
Foam control is vital in pulp and paper manufacturing to
improve drainage, reduce chemical use, and enhance sheet quality.
High-performance silicone and polymer-based defoamers are widely used,
especially in recycled fiber mills, due to their ability to perform under
high-shear and alkaline conditions.
The industry’s shift toward sustainable solutions is also boosting demand for
biodegradable defoamers.
