Hazard Identification

Classification: Not classified as hazardous according to GHS
Major Hazards: Mild skin and eye irritant, slippery surfaces if spilt
Signal Word: Not required
Pictograms: Not required
Other Hazards: Avoid release to the environment, spills may cause slip hazard

Composition / Information on Ingredients

Chemical Identity: Polyether-Modified Polydimethylsiloxane
CAS Number: Proprietary blend
Content: 20–40% Polyether-Modified Silicone Oil, 1–5% Nonionic Surfactants, Balance Water
Other Components: Stabilizers and Preservatives (trace)

First Aid Measures

Inhalation: Move to fresh air, seek medical attention if symptoms persist
Eye Contact: Rinse thoroughly with water for at least 15 minutes, remove contact lenses, seek medical evaluation for persistent irritation
Skin Contact: Wash with soap and plenty of water, remove contaminated clothing, seek assistance if irritation develops
Ingestion: Do not induce vomiting, rinse mouth with water, obtain medical attention if discomfort continues
Most Important Symptoms: Mild irritation of skin, eyes, respiratory tract

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, foam, dry chemical, carbon dioxide
Fire Hazards: Product is non-flammable, may produce small amounts of formaldehyde and silicon oxides at high temperature
Protective Equipment for Firefighters: Standard protective gear, self-contained breathing apparatus if smoke or fumes present
Special Hazards: Slippery floor conditions, thermal decomposition at high temperatures leads to hazardous vapors
Other Information: Cool containers exposed to fire with water spray

Accidental Release Measures

Personal Precautions: Wear gloves, goggles, non-slip footwear, prevent skin and eye contact
Environmental Precautions: Prevent from entering drains, surface water, or soil
Clean-up Methods: Absorb with inert material (sand, earth), collect in containers for disposal, wash spill area with water
Special Spill Handling: Use caution due to risk of slipping, ventilate area if necessary

Handling and Storage

Handling: Use in well-ventilated area, wear appropriate protective equipment, avoid ingestion and contact with eyes or skin, maintain clean working area to prevent slip hazard
Storage Conditions: Store in original tightly closed container, in a cool, dry, well-ventilated location, avoid freezing and high temperatures, keep away from food and drink
Incompatibilities: Strong oxidizers, acids, alkalis
Recommendations: Regularly check containers for leaks or degradation

Exposure Controls and Personal Protection

Control Parameters: No specific occupational exposure limits established for main components
Engineering Controls: Provide local exhaust ventilation if mist or aerosol generated
Personal Protection: Gloves (nitrile or neoprene), chemical safety goggles, protective clothing, eye wash stations available in the work area
Hygiene Practices: Wash hands after handling, avoid eating or drinking near work area, remove contaminated clothing and wash before reuse

Toxicological Information

Acute Toxicity: Oral and dermal toxicity considered low (data based on similar compositions)
Skin Corrosion/Irritation: May cause mild irritation
Serious Eye Damage/Irritation: May cause mild irritation, redness
Inhalation: Inhalation of mist may cause mild respiratory irritation
Chronic Effects: No known serious chronic effects
Carcinogenicity/Mutagenicity: Not classified as carcinogen or mutagen
Aspiration Hazard: Not considered an aspiration hazard
Sensitization: No data indicating sensitization potential

Ecological Information

Ecotoxicity: Limited data; components expected to have low acute aquatic toxicity
Persistence and Degradability: Silicone portion is not readily biodegradable, polyether may degrade more quickly in the environment
Bioaccumulation Potential: Low, due to large molecular size
Mobility in Soil: Product shows some mobility in aqueous systems, likely binds to soil particles
Other Adverse Effects: Emulsions may cause surface films on water bodies, discourages oxygen transfer

Disposal Considerations

Safe Disposal Methods: Dispose of in accordance with local, regional, and national regulations as non-hazardous waste; do not pour into drains or waterways
Contaminated Packaging: Empty containers must be thoroughly rinsed before reuse or recycling
Disposal Cautions: Avoid landfill release, incineration preferred if permitted, consult certified waste contractor

Transport Information
