Product Name: Silicone Antifoam Emulsion, 30% concentration
Appearance: Milky white, opaque liquid
Main Use: Controls, reduces, or eliminates foam in industrial water and process fluids in industries like food processing, textiles, and chemical manufacture
Key Chemical Family: Polydimethylsiloxane-based silicone compounds suspended in water with emulsifying agents
Distinctive Odor: Slightly characteristic, often undetectable at common concentrations
Primary Health Risk: Eye and skin irritation possible after prolonged or repeated exposure
Environmental Concern: Spillage into natural water sources may harm aquatic life due to surfactant properties
Physical Hazard: Non-flammable, but emulsifiers may support combustion under certain conditions
Chronic Exposure: Chronic effects rarely reported, but sensitive individuals may develop dermatitis
Inhalation Risk: Mist or aerosol can be irritating to the respiratory system when handled in confined, unventilated areas
Silicone Compound: Polydimethylsiloxane emulsion approx. 30%
Water: 65–70%
Emulsifiers / Surfactants: 1–5%, non-ionic and/or anionic types
Possible Additives: Trace preservatives to limit microbial growth, no hazardous impurities intentionally included
Skin Contact: Wash with plenty of water and mild soap, remove contaminated clothing
Eye Contact: Immediately flush eyes with clean running water for several minutes, seek medical attention if irritation persists
Inhalation: Move to fresh air, seek attention if breathing discomfort continues
Ingestion: Rinse mouth with water, drink water to dilute, do not induce vomiting, seek care if symptoms develop
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, or water spray
Special Hazards: Thermal decomposition can produce trace levels of formaldehyde, carbon oxides, silicon oxides
Protective Equipment: Firefighters need standard protective gear and self-contained breathing apparatus
Flammability: Aqueous base makes ignition unlikely, but dried residues may burn
Personal Precautions: Wear gloves, goggles, and non-absorbent footwear to prevent direct skin or eye contact
Spill Containment: Prevent entry to drains and waterways, absorb with inert material like sand or earth
Clean-up Approach: Shovel or sweep up residues, wash affected area with plenty of water, dispose as per regulations
Environmental Precaution: Immediate action limits spread into soil or water ecosystems
Safe Handling: Avoid splashing, keep containers tightly closed when not in use, provide adequate ventilation
Hygiene Advice: Wash hands after handling, avoid eating, drinking, or smoking near the product
Storage Conditions: Store in original or compatible containers, keep cool, away from direct sunlight and extremes of temperature
Incompatible Storage: Strong acids, alkalis, oxidizers may destabilize emulsion and release hazardous components
Engineering Controls: Local exhaust ventilation in process areas, splash guards on tanks
Skin Protection: Use protective gloves (nitrile, rubber), long sleeves recommended
Eye Protection: Safety goggles or face shield for splash risk
Respiratory Protection: Not usually required unless aerosol generates; then use suitable mask
Exposure Limits: No established occupational exposure limits for polydimethylsiloxane, but emulsifying agents may have guidelines
Physical State: Liquid emulsion
Color: White to off-white
Odor: Faint, nearly none
pH: Typically 6–8
Boiling Point: Approximates that of water
Density: Around 1.0 g/cm³
Solubility: Dispersible in water
Viscosity: Moderate, depends on exact formulation
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Will not react violently with most chemicals
Incompatible Materials: Strong oxidizing or reducing agents, acids, and base concentrated solutions
Hazardous Decomposition: Small amounts of formaldehyde, carbon dioxide, and silicon oxides can evolve above 150°C
Polymerization: Will not occur under normal work conditions
Acute Toxicity: Very low, significant symptoms unlikely under normal use
Eye Irritation: Moderate irritation possible with direct contact
Skin Irritation: Prolonged exposure may lead to dryness or mild dermatitis, allergic reactions rare
Sensitization: No strong evidence of sensitizing properties
Chronic Effects: Long-term exposure shows little evidence of systemic toxicity in animal studies
Inhalation Effects: Mist or aerosol may cause respiratory discomfort
Environmental Fate: Silicone component persists, not readily biodegradable
Aquatic Toxicity: Surfactants may present moderate risk to aquatic species; silicone oil itself is not acutely toxic
Mobility: Product may spread easily in water, can foam on surface
Bioaccumulation: Low for the silicone polymer, but possible for surfactant fragments
Preferred Disposal: Treat as non-hazardous industrial waste if not contaminated with hazardous materials
Incineration: Only at facilities capable of handling silicone waste
Sewer Disposal: Avoid, since product contributes to foaming and can affect wastewater treatment
Packaging: Empty containers thoroughly, rinse before recycling or disposal
Local Requirements: Consult local, regional, or national regulations for compliance
UN Number: None assigned as typically non-dangerous for transport
Transport Hazard Class: Generally not regulated
Packing Group: Not classified
Special Transport Advice: Prevent freezing or overheating, secure containers upright
Environmental Precautions: Accidental releases to water or soil should be minimized in shipment
Classification: Not considered hazardous under GHS standards in most regions
Labelling: Product labels often state “Industrial Use Only”, with risk and safety phrases where applicable
Ingredient Lists: Components may appear on national chemical inventories such as TSCA or EINECS
Restrictions: Some areas set discharge limits for silicone oils, especially where foam control affects effluent
Worker Training: Handling guidelines encourage every worksite to give exposure reduction training and make safety data accessible
