SILAD 210 FG FOOD GRADE DEFOAMER 10% EMULSION SILICON BASED

Silad 210 FG Description — Food-Grade Foam Control Agent for High-Purity Aqueous Systems

At Quimiconsult we offer Silad 210 FG, a food-grade defoamer formulated as a low-viscosity, water-based silicone emulsion, designed specifically for effective foam control in food, beverage, meat processing, food product washing and sanitizing, supplement manufacturing, plant protein processing and condiment manufacturing processes, where regulatory compliance, purity, food safety and traceability are non-negotiable requirements. It is a homogeneous, stable, easy-to-handle and cost-effective foam control agent that excels in applications with nonionic and anionic surfactants, delivering superior performance under neutral, slightly alkaline or acidic pH conditions and effectively withstanding a wide process pH range. It is supplied as a homogeneous creamy white emulsion, with an active ingredient content of 10% by weight, specific gravity of 0.90 to 1.10 at 25 °C, viscosity of 1,000 to 2,500 cP (measured with spindle No. 63 at 100 rpm), 1% solution pH in the range of 3.5 to 4.50, and it is fully dilutable in water. It is kosher and is manufactured in a plant certified under the SQF (Safe Quality Food) scheme, recognized by the Global Food Safety Initiative (GFSI) as one of the most rigorous food safety management systems internationally, ensuring traceability, process control and consistent quality in every batch produced.

Silad 210 FG belongs to the category of polydimethylsiloxane (PDMS) defoamers emulsified in water with a nonionic emulsifier, one of the most established and effective technologies for foam control in aqueous systems. Silicone defoamers are widely recognized worldwide as the technical solution of choice when you need high efficiency at very low dosage (typically 50 to 500 ppm on the foaming system), long-lasting defoaming action (they are not used up quickly like other defoamers), compatibility with food systems (in the case of food grades such as Silad 210 FG), chemical stability under process conditions (including heat treatments such as pasteurization and cooking) and organoleptic neutrality (they do not transfer flavor, color or odor to the finished product). Silad 210 FG's aqueous emulsion form, rather than pure silicone, makes it easier to incorporate uniformly into the foaming system, improves distribution of the active in the aqueous medium and allows precise dosing with standard metering pumps.

Unlike organic defoamers based on vegetable oils, fatty acids, fatty alcohols or esters, silicone defoamers such as Silad 210 FG offer decisive advantages for the modern food industry: greater potency per unit of mass (which reduces the required dosage and therefore the cost per kilo of processed product), greater stability over time without rapid degradation in the process, no contribution to off-flavors or rancidity that vegetable oil–based defoamers can cause over time, resistance to the high temperatures typical of food processes (pasteurization, cooking, sterilization), compatibility with virtually all surfactants used in CIP cleaning and process formulations, and a solid regulatory profile for use in food and processing applications under specific certified grades.

In addition, Silad 210 FG is designed to deliver high production yield in food applications: by effectively controlling foam formation during critical operations (mixing, filling, agitation, transfer, evaporation, fermentation, washing), it makes it possible to maximize the usable volume of tanks and equipment (foam takes up volume without adding product), reduce downtime caused by overflows or extra cleaning, improve filling and dosing accuracy, protect sensors and control devices that can be affected by persistent foam, and maintain stable process conditions throughout full production shifts.

At Quimiconsult, located in San Nicolás de los Garza, Nuevo León, we distribute Silad 210 FG with nationwide coverage, application technical support, batch certificates of analysis, and up-to-date technical data sheets (TDS) and safety data sheets (HDS/SDS), serving food and beverage plants, meat and poultry processors, juice and soft drink plants, canned goods, jam and jelly factories, food cleaning solution manufacturers, fruit, vegetable and seafood washing plants, dietary supplement manufacturers, condiment and flavoring plants, soy protein processors, pet food plants, and production, quality and development departments throughout Mexico.

Silad 210 FG Technical Specifications and Physicochemical Properties

• pH (1% solution): 3.5 to 4.50 (slightly acidic).

Beyond these basic parameters, Silad 210 FG has a set of functional properties that are what really determine its value in industrial food applications:

• High defoaming efficiency at very low dosage: typical recommended starting doses are 50 to 500 ppm on the foaming system, which translates into a very competitive cost per kilo of processed product.
• Long-lasting defoaming action: silicone defoamers remain active for extended periods compared with traditional organic defoamers, which are used up more quickly.
• Compatibility with virtually all surfactants, especially nonionic and anionic ones, which are widely used in food formulations, CIP, product washing and process operations.
• Stability over a wide pH range: reliable performance under neutral, slightly alkaline and acidic conditions, covering virtually all conventional food processes.
• Thermal stability: adequate resistance to typical food processing temperatures (pasteurization, cooking, mild sterilization), although prolonged storage at extreme temperatures (excessive heat or freezing) that can separate the emulsion should be avoided.
• Water dilutability: complete, which makes it easy to prepare dilutions for continuous dosing (typically 1 part defoamer in 3 to 10 parts water or process liquid).
• Organoleptic compatibility: it adds no detectable flavor, color or odor to the finished product at use concentrations, a critical property in food applications where sensory quality is a priority.
• Suitable for continuous dosing: designed to be pumped and injected continuously into process lines with standard dosing equipment.
• Storage stability: the product maintains homogeneity and specifications throughout its shelf life when stored under proper conditions; in the event of partial separation due to exposure to extreme temperatures, it is easily restored by gently agitating the container.
• Safe handling profile: food-grade silicone defoamer emulsions are widely recognized as substances with a low toxicological profile under recommended use conditions, with a long history of safe use in the food industry worldwide.

The Silad Family at Quimiconsult — Food-Grade and Industrial Defoamers

Quimiconsult offers the Silad family of silicone emulsion defoamers, covering the two most in-demand industrial application categories so each plant can select the optimal product according to the regulatory grade required by the end application:

• Silad 210 FG (Food Grade) — the product described on this page: a 10% active silicone emulsion defoamer, food grade, kosher, manufactured in a plant certified under the SQF scheme. Designed for all applications that require a defoamer suitable for food contact, food and beverage processing, food product washing, CIP in food plants and supplement manufacturing. Compatible with nonionic and anionic surfactants. Wide effective pH range (neutral, slightly alkaline, acidic).
• Silad 210 (industrial grade): a silicone emulsion defoamer with a technical profile similar to Silad 210 FG in defoaming efficiency, but intended for non-food industrial applications where food safety regulations do not apply. Ideal for industrial chemical processes, treatment of industrial water not intended for human consumption, industrial cleaning product formulations, chemical, paper, textile, paint and coating manufacturing processes, agrochemical formulations and industrial applications in general where efficient foam control is required without the need for food certification. This option can offer a cost advantage over the food grade when the end application does not require it.

Key selection criterion between Silad 210 FG and industrial Silad 210: if your process involves direct or indirect contact with food products intended for human or animal consumption (including processes where the defoamer may come into contact with food even as a processing aid, food product washing, CIP in food plants, supplement manufacturing), the FG (Food Grade) version, Silad 210 FG, must be used. If the process is strictly industrial with no food contact, the industrial version Silad 210 can be used to optimize cost. If in doubt about which version applies to your application, using the food-grade version is always recommended (Silad 210 FG) to ensure regulatory compliance and traceability. Contact our technical team for specific advice on your case.

How Does Silad 210 FG Work? — Mechanism of Action of the Silicone Defoamer

Unlike traditional organic defoamers (vegetable oils, fatty alcohols, fatty acids, esters), which act mainly by partially dissolving in the foaming phase, silicone emulsion defoamers such as Silad 210 FG work through a physical mechanism that ruptures foam films and is highly efficient, long-lasting and selective:

The active reaches the air-liquid interface: once dosed and incorporated into the foaming system with gentle agitation, the Silad 210 FG emulsion releases fine droplets of polydimethylsiloxane (PDMS) that migrate to the air-liquid interface of the foam bubbles. This migration occurs because silicone has a very low surface tension (typically 20-21 mN/m) compared with that of water (72 mN/m) and foaming surfactant solutions (typically 30-40 mN/m), so the silicone is thermodynamically driven out of the aqueous phase toward the interface.

Insertion into the foam film and local destabilization: on reaching the interface, the silicone droplets insert themselves into the thin film of the foam bubble (lamella). Because silicone is incompatible with organic foaming surfactants and has a very different surface tension, it locally breaks the surfactant film that keeps the bubble stable.

Thinning and mechanical rupture of the bubble: once the surfactant film has broken locally at the point of contact with the silicone, the bubble lamella thins rapidly due to capillary forces (reverse Marangoni effect) until it reaches a critical thickness at which the film ruptures mechanically and the bubble collapses. The gas in the bubble is released and the liquid drains back into the bulk phase.

Cascade effect: the silicone droplets released after a bubble collapses are available to attack adjacent bubbles, creating a cascade effect of foam breaking that spreads rapidly through the entire foaming system.

Persistence and durability: since the silicone is not chemically consumed during the process (unlike organic defoamers, which can be metabolized or solubilized by surfactants), it remains available in the system to suppress new foam formation for an extended period after the initial dose. This explains the greater durability and lower dosage required of silicone defoamers compared with organic alternatives.

Surfactant compatibility: formulating Silad 210 FG with a nonionic emulsifier avoids unfavorable interactions with the anionic surfactants common in food and CIP cleaning formulations, maintaining defoaming efficacy in the presence of detergents and process surfactants.

Stability over a wide pH range: the polydimethylsiloxane chain does not undergo significant hydrolysis under normal food pH conditions (acidic to slightly alkaline), ensuring consistent performance in processes as diverse as acidic beverages (juices, soft drinks), vegetable washing (neutral pH), alkaline CIP (high pH) and meat processing (near-neutral pH).

Silad 210 FG vs Silad 210 (Industrial Grade) — Selection Guide

One of the most frequent technical questions is how the food grade (Silad 210 FG) differs from the industrial grade (Silad 210). This is the selection guide:

Choose Silad 210 FG (food grade, kosher, SQF plant) — the product described here — when:

• Your process involves direct or indirect contact with food products intended for human or animal consumption.
• You operate a food, beverage, meat, dairy, juice, canned goods, supplement, condiment or plant protein processing plant.
• You carry out food product washing (vegetables, fruit, seafood, grains).
• You apply the defoamer in CIP operations in food plants where residues may contact finished product.
• You require kosher certification for your inputs because of your target market or customer strategy.
• Your food safety management system (HACCP, FSSC 22000, BRC, SQF, IFS) requires documented traceability of processing aids.
• Your customer or destination regulations require food-grade defoamers.

Choose Silad 210 (industrial grade) when:

• Your process is strictly industrial with no food contact.
• You operate plants for industrial chemicals, paper, textiles, paints, coatings, non-food agrochemicals, treatment of industrial water not intended for human consumption, or industrial manufacturing processes.
• You want to optimize cost when the application does not require food grade.

Practical decision rule: if your application has any point of contact, transfer or assistance on a food line, use Silad 210 FG. The cost difference between food grade and industrial grade is marginal compared with the risk of regulatory non-compliance, product recall or customer complaints for using a non-certified defoamer. If in doubt about which one applies to your application, contact our technical team for specific advice.

Recommendations for Use, Dosage and Incorporation of Silad 210 FG

To get maximum defoaming efficacy from Silad 210 FG, we recommend following the manufacturer's usage protocol:

Pre-mixing: the emulsion should be gently mixed before use to ensure uniformity. In drums that have been standing for a long time, gently agitate or recirculate before dosing.

Method of application: Silad 210 FG can be used in two ways:

• As a concentrate: direct dosing of the 10% active emulsion at the point of application.
• Diluted in water or process liquid (the recommended form for maximum cost-effectiveness and better distribution): mix 1 part Silad 210 FG with 3 to 10 parts of the selected diluent (process water or process liquid), stirring gently until a uniform mixture is obtained.

Continuous mixing of the dilution: it is recommended to keep the diluted defoamer under gentle, continuous agitation during intermediate storage to ensure uniformity and prevent separation during long intervals between doses.

Point of incorporation: to maximize cost-effectiveness and efficacy, the defoamer should be pre-diluted and added continuously at a processing stage before the stage where foam forms (preventive dosing). This practice is more efficient than reactive dosing (adding defoamer after foam has already formed), since it prevents foam from forming rather than eliminating it once formed.

Suggested starting concentrations: 50 to 500 ppm of Silad 210 FG on the foaming system (not on the diluent). The exact range within this window depends on:

• Intensity of foam formation in the specific process.
• Type and concentration of surfactants present in the system.
• Operating temperature and pH.
• Residence time of the product in the foaming tank or equipment.
• Target result (total foam suppression vs partial control).

It is recommended to start with the lowest dose in the range (50-100 ppm) and adjust upward progressively until the desired foam control is achieved, optimizing dosage and cost.

Dosing equipment: standard diaphragm, peristaltic or piston metering pumps are suitable. For continuous dosing on process lines, flow-controlled injection systems help maintain a constant concentration.

Performance verification: once the dosage has been set, we recommend monitoring the system's behavior visually or with foam sensors during the first weeks of use, fine-tuning the dosage according to actual process conditions.

Silad 210 FG Compatibilities and Incompatibilities

Silad 210 FG is compatible with: water and aqueous solutions in any proportion; nonionic surfactants (ethoxylated alcohols, ethoxylated esters, ethoxylated alkylphenols — where applicable — food-grade-compatible polysorbates); anionic surfactants (sulfates, sulfonates, soaps, at typical process concentrations); dilute organic and inorganic acids (citric, ascorbic, phosphoric and lactic acid — common in the beverage and food industry); moderate bases (sodium hydroxide at alkaline CIP concentrations, carbonates); organic and inorganic salts at typical concentrations; proteins, starches, hydrocolloids and other food ingredients; standard food preservatives (sorbates, benzoates, parabens where applicable); flavors, colorants and food additives.

It requires special precautions or considerations with:

• Cationic surfactants at high concentration: they can alter the stability of the nonionic emulsion. In applications that combine Silad 210 FG with cationic sanitizers (quaternary ammonium compounds), verify compatibility with a specific test.
• Extreme temperatures during prolonged storage: excessive heat (>40 °C prolonged) or freezing can cause the emulsion to separate. If separation occurs, thaw if frozen, gently agitate the contents and use normally. Avoid prolonged exposure to extreme temperatures during storage.
• Strong oxidizing agents at high concentration: concentrated hydrogen peroxide, highly concentrated hypochlorites or peracetic acid can affect the stability of the emulsion and its functionality. In washing and sanitizing systems with these agents, verify proper dosing and compatibility under the specific conditions.
• Very intense, prolonged shear: although the product is stable under normal agitation, extreme shear over long periods can affect emulsion stability. For diluted preparations, gentle agitation is preferable to high shear.
• Packaging materials and equipment: compatible with stainless steel, glass, polyethylene (HDPE, LDPE), polypropylene, PVC and standard food-grade plastics. Verify compatibility with the specific elastomers of gaskets and seals in specific applications.

Silad 210 FG Storage, Packaging and Shelf Life

Silad 210 FG is available in 200 kg drums for regular operations and in bulk on request for large industrial consumers and plants with dedicated defoamer storage tanks.

To ensure the quality and performance of the product throughout its shelf life, we recommend:

• Store in the original, tightly closed container when not in use. A tight seal prevents contamination, evaporation of water from the emulsion and absorption of external odors.
• Store at controlled room temperature (ideally 15-30 °C).
• Avoid prolonged exposure to extreme temperatures of heat (>40 °C sustained) or freezing, which can cause separation of the emulsion.
• If separation occurs due to exposure to extreme temperatures: if frozen, first thaw at room temperature; gently agitate the contents to reincorporate the phases; use as usual. Reversible separation does not compromise product performance once homogenized.
• Keep away from direct sunlight, heat sources, incompatible materials and strong odors.
• Rotate inventory using a FIFO system (first in, first out) to use older batches before newer ones.

The shelf life of the product under proper storage conditions is typically 12 to 18 months from the date of manufacture, according to the supplier's specification and batch. The official expiration date is shown on the original container and on the Certificate of Analysis of the corresponding batch.

Safety, Handling and Regulatory Considerations

Silad 210 FG is a food-grade silicone emulsion with a well-characterized toxicological profile, widely recognized as a low-hazard substance under normal conditions of industrial food use. Food-grade emulsified polydimethylsiloxane (PDMS) defoamers have a long history of safe use in the food industry worldwide under the regulations of the main health authorities.

The recommended personal protective equipment (PPE) during industrial handling includes safety glasses to avoid eye contact with splashes, gloves for industrial food use (nitrile or equivalent suitable for the food industry) to avoid prolonged skin contact, appropriate work clothing according to plant protocols, and work in areas with adequate ventilation. No specialized PPE for hazardous substances is required under normal handling conditions.

Spill handling: Silad 210 FG spills are slippery and pose a fall hazard. Contain with inert absorbents (vermiculite, sand, industrial absorbent pads), collect with shovels or vacuum, and dispose of in accordance with current waste legislation. Wash the area with water and detergent to remove slippery residues. Report significant spills according to plant protocols.

Handling of empty containers and waste: dispose of in accordance with current waste legislation. Under most regulations, food-grade silicone defoamer emulsion waste is not classified as hazardous in typical commercial quantities, although it may require treatment before final disposal depending on volume and local regulations.

Frequently Asked Questions about Silad 210 FG

What is Silad 210 FG and what is it used for?

Silad 210 FG is a food-grade defoamer formulated as a low-viscosity silicone emulsion with 10% active ingredient in a water base. It is used to control foam formation during food processing operations in the food, beverage, juice, sauce, canned goods, jam, meat, poultry, seafood, dietary supplement, condiment, flavoring, food cleaning solution, vegetable washing, and soy and other plant protein processing industries. It holds kosher certification and is manufactured in a plant certified under the SQF (Safe Quality Food) scheme, recognized by GFSI.

What is the difference between Silad 210 FG and Silad 210 (industrial grade)?

The fundamental difference lies in the regulatory grade and intended use. Silad 210 FG is food grade, kosher, manufactured in an SQF-certified plant and designed for applications with direct or indirect food contact. Silad 210 is industrial grade, formulated for industrial applications without food contact (industrial chemicals, paper, textiles, paints, coatings, non-food industrial water treatment). The defoaming efficiency profile is similar for both, but the food grade includes traceability, certifications and manufacturing controls specific to food safety. If your process involves food contact, the FG version must be used.

At what concentration is Silad 210 FG used?

The suggested starting concentration is 50 to 500 ppm of Silad 210 FG on the foaming system (that is, on the product or process that generates the foam, not on the diluent). It is recommended to start with the lowest dose in the range (50-100 ppm) and gradually adjust upward until the desired foam control is achieved, optimizing dosage and cost. The exact concentration depends on the foaming intensity of the process, type of surfactants present, temperature, pH and residence time.

How is Silad 210 FG diluted and applied?

Silad 210 FG can be used in two ways: as a concentrate (direct dosing at 10% active) or diluted in water or process liquid (the recommended form for maximum cost-effectiveness). Dilution is done by mixing 1 part defoamer with 3 to 10 parts diluent (water or process liquid), stirring gently until a uniform mixture is obtained. It is recommended to keep the dilution under gentle, continuous agitation during intermediate storage to preserve uniformity. For maximum efficacy, dose it continuously at a stage before foam forms (preventive rather than reactive dosing).

Is Silad 210 FG kosher?

Yes, Silad 210 FG holds kosher certification. Specific documentation (current kosher certificate, certifying agency) is available on request for your regulatory files and customer audits.

In what type of plant is Silad 210 FG manufactured?

Silad 210 FG is manufactured in a plant certified under the SQF (Safe Quality Food) scheme, one of the most rigorous food safety management systems internationally, recognized by the Global Food Safety Initiative (GFSI).

Does Silad 210 FG work with detergents and CIP cleaners?

Yes, Silad 210 FG is compatible with virtually all surfactants, especially nonionic and anionic ones, which are the most common in food detergent formulations and CIP (Clean-in-Place) solutions. It is widely used in CIP circuits in food, meat, dairy, soft drink and brewing plants to control foam generated by surfactants during cleaning and rinsing. It works over a wide pH range (acidic, neutral, slightly alkaline), making it suitable for both acid CIP (mineral scale removal) and alkaline CIP (organic soil removal).

Does it add flavor, odor or color to the finished product?

No, at the recommended use concentrations (50-500 ppm), Silad 210 FG adds no detectable flavor, color or odor to the finished product. This property is one of the fundamental reasons food-grade silicone defoamers are preferred over organic defoamers (based on vegetable oils), which can contribute rancid flavors over time. Organoleptic neutrality is especially critical in applications such as beverages, juices, dairy, jams and supplements, where the sensory profile is a priority.

What pH range does Silad 210 FG work in?

Silad 210 FG is effective over a wide pH range, delivering superior performance under neutral, slightly alkaline and acidic conditions. This covers virtually all conventional food processes: acidic beverages (citrus juices, soft drinks), vegetable washing (neutral pH), alkaline CIP (high pH), meat processing (near-neutral pH), canned goods and jams (acidic pH). The polydimethylsiloxane chain (the main active) does not undergo significant hydrolysis under normal food pH conditions.

What happens if Silad 210 FG separates during storage?

Emulsion separation can occur if the product is exposed to prolonged extreme temperatures (excessive heat or freezing) during storage. If separation occurs: if the product is frozen, first thaw it at room temperature; gently agitate the contents to reincorporate the phases until a homogeneous appearance is obtained; use as usual. Reversible separation does not compromise product performance once homogenized. To prevent separation, store at controlled room temperature (15-30 °C) in a tightly closed container.

How long does Silad 210 FG keep in storage?

In the original, tightly closed container, stored at controlled room temperature (15-30 °C) away from extreme heat, freezing, direct sunlight and strong odors, Silad 210 FG has a typical shelf life of 12 to 18 months from the date of manufacture, according to the batch specification. The official expiration date is always shown on the original container and on the Certificate of Analysis of the corresponding batch.

What is the active ingredient in Silad 210 FG?

Food-grade silicone emulsion defoamers such as Silad 210 FG are typically based on polydimethylsiloxane (PDMS) as the active ingredient, emulsified in water with food-grade nonionic emulsifiers. The active ingredient content is 10% by weight, a value optimized for industrial dilution, dosing and application. The detailed composition of the product is available in the safety data sheet (HDS/SDS) and the complete technical data sheet.
