A defoamer destroys foam that has already formed in a process system. An antifoaming agent is added preventively to stop foam from developing before it occurs. In most industrial applications, the same chemical compound performs both functions — it collapses active foam and inhibits its return. INVINO supplies both defoamer and antifoam formulations selected based on your process timing and dosing strategy. Browse our full product portfolio →

Selection depends on five primary variables: process medium chemistry (aqueous or non-aqueous), operating temperature, pH range, mechanical shear rate, and any regulatory requirements such as food-grade or Halal compliance. INVINO's application engineers perform parameter benchmarking and laboratory simulation to identify the correct active component — silicone, fatty alcohol, polyether, polyether ester, or mineral oil — before shipment. See our industry application guide →

Fatty alcohol-based defoamers are the standard selection for paper machine wet-end white water systems and high-temperature brownstock washing loops in kraft pulp mills. They provide alkali stability and low interference with paper machine chemistry. Silicone emulsion antifoams are used in drainage and flotation deinking stages where higher knockdown speed is required. View pulp & paper defoamer specifications →

Polyether block copolymer defoamers are the standard selection for submerged aerobic fermentation — they are non-toxic to microorganisms and metabolically inert. For food-grade or pharmaceutical fermentation, food-compatible polyether or fatty acid antifoams are required. INVINO engineers simulate your bioreactor conditions — temperature, agitation speed, and medium composition — in our R&D laboratory before confirming the formulation.

Yes. INVINO holds Halal certification and Food Grade Production Licenses for applicable product lines. Food-compatible defoamers use approved active components — polyether derivatives or fatty acid esters — and comply with relevant food contact regulations. Third-party compliance reports covering REACH SVHC 241, heavy metal analysis, PAHs screening, phthalates restriction, and microbiological assay are available upon request. View all certificates →

Yes. INVINO provides full OEM and ODM antifoam manufacturing including custom active-content concentration, toll blending, and private label packaging. Formulations are developed based on client-provided process parameters and validated in our R&D laboratory before batch production. Minimum order quantities and packaging configurations are confirmed during the technical consultation stage. Explore OEM/ODM services →

Submit your process system variables — operating temperature, fluid pH, mechanical shear level, surfactant matrix, and any regulatory requirements — via our contact page. INVINO provides complimentary laboratory-grade samples (typically 200g to 500g) matched to your specific process conditions. Samples are dispatched via international express (DHL, FedEx, or UPS) within 6 to 7 business days. Each shipment includes the product TDS and SDS. Download technical documents →

INVINO defoamers are available in three standard configurations: 25 kg plastic drums, 200 kg metal or plastic barrels, and 1,000 kg IBC composite containers. All containers are moisture-sealed to protect emulsion active content from atmospheric exposure during international shipping. Custom packaging can be arranged for OEM and private label orders. Contact our team to confirm packaging options for your specific product line.

General dosage benchmarks range from 100 to 500 ppm (0.01% to 0.05% by weight) relative to total liquid volume. Exact dosage depends on the process medium's surfactant load, temperature, and shear conditions. Overdosing can cause surface defects in coating or paper applications; underdosing results in insufficient foam knockdown. Precise thresholds are verified during laboratory pre-screening before sample dispatch — we do not recommend adjusting dosage without first consulting our application engineers.

INVINO silicone and polyether emulsion defoamers maintain validated performance for 6 to 12 months when stored in original sealed containers at 5°C to 40°C, away from direct sunlight and freezing conditions. Shelf life data, storage conditions, and safety information are documented in the product Safety Data Sheet (SDS). Powder defoamers typically have longer shelf stability — consult the specific product TDS for confirmation. Download SDS & TDS →

Performance loss is usually caused by changes in process conditions rather than product failure. Common triggers include sudden increases in organic loading, surfactant concentration shifts, pH drift, or temperature fluctuations. Do not increase dosage arbitrarily — this can introduce new process problems. Document your current fluid pH, temperature, and any recent process changes, then contact INVINO's application engineers. Our team will re-test the formulation against your updated process variables in our laboratory and recommend a corrective action. Contact our engineers →
