How to Optimise Defoamer Performance

To get the best results from defoamers, it’s essential to use them strategically. Start by choosing the right type based on your process conditions—factors like temperature, pH, and foam stability matter. Always add defoamers at the right stage, whether during mixing, processing, or post-production, to maximise efficiency while minimising waste. Proper dosing is key—too little won’t control foam, and too much can lead to surface defects or contamination.

A common mistake is adding defoamers too late when the foam has already built up, making control harder and less effective. Incompatible defoamers can also cause separation issues, reducing performance. Another pitfall is improper dispersion—some defoamers need thorough mixing to work correctly. By following best practices and avoiding these missteps, you can optimise defoamer performance, reduce costs, and keep operations running smoothly.

“To successfully predict the antifoam addition in a proactive manner for an industrial data set (about half a million instances for 163 batches), we use a genetic algorithm called TPOT (Tree-based Pipeline Optimization Tool), and to build antifoam profiles, we use exploratory time-series analysis. Through this work, we have successfully demonstrated the following: (1) the ability of automated machine learning (AML) to predict AFA addition for multiple strains of microorganisms using large-scale industrial fermentation data set and (2) the edge of data-guided antifoam profiles based on time series.” – Industrial & Engineering Chemistry ResearchVol 61/Issue 15

Chemistry of Defoamers

Which defoamer is most appropriate for a given solution depends on several factors, including the chemical composition & physical properties of the foaming solution, the method of foam generation and the type of foam present.

Typically, defoamers are formulated around a carrier fluid, which may be a hydrocarbon, silicone oil, vegetable oil, synthetic polymer, etc. Active ingredients, which help with spreading or destabilizing foam, can include waxes, metal salts, silicas or other hydrophobic particles. An emulsification system can be incorporated to optimize spreading and compatibility of the defoamer to a given foaming system and depending on the chemistry, stabilizing agents such as cellulosic or acrylic thickeners may be added to improve shelf stability.

Crucible maintains an extensive portfolio of defoamer chemistries. The following represent some of the broader categories of defoamer and their common uses:

Silicone & Organo-Silicone Defoamers

Silicone & organo-silicone defoamers are highly efficient and broadly effective in a wide variety of applications. These products are based on silicone oils (polydimethylsiloxane or modified siloxanes), often with hydrophobic silica dispersed in solution. Silicone oils have a very low surface tension, which contributes to rapid spreading at the gas-liquid interface and facilitating the weakening of the foam films and penetration of the bubble wall.

Crucible supplies these types of products as 100% active silicone compounds, dispersions, or as emulsions, which are readily dispersible in aqueous systems.

Non-Silicone Defoamers

Non-silicone defoamers can be further broken down into several categories. The most broadly used are mineral oil-based due to their optimal performance and lower cost. Non-silicone defoamers are also formulated with vegetable oils, white oils, esters, fatty alcohols, synthetic polymers, etc., depending on the characteristics, compatibility, and requirements of each foaming system. These defoamers often include hydrophobic particles (e.g. silicas, waxes, etc.) to boost performance and may be supplied as insoluble or partially soluble dispersions, emulsions or self-emulsifiable, 100% active liquids.

Within this category, Crucible also supplies VOC, APE (alkylphenol ethoxylate) and silicone-free defoamers with our Foamkill™ V product line. These products are optimal replacements for traditional mineral-oil based products used in adhesives, defoamers for paint and coatings, and numerous other applications.
