Product Name: Water-Resistant Aluminum Silica Gel - W
Other Names: Aluminum Modified Silica Gel, Water-Repellent Silica Gel
Chemical Family: Amorphous Silica, Modified with Aluminum Oxide
Product Use: Desiccant for gas drying, moisture protection, industrial filtration
Manufacturer: See supplier information on packaging
Emergency Contact: Local poison control center or manufacturer’s emergency line
Classification: Not classified as hazardous under GHS
Main Hazards: Prolonged inhalation may irritate respiratory tract; repeated skin contact can cause dryness
Label Elements: No pictogram required
Precautionary Statements: Avoid generating dust; use protection when handling bulk material
Potential Health Effects: Eye and skin irritation, especially with long-term exposure to dust; ingestion unlikely to cause acute effects
Chemical Composition: Amorphous Silica (SiO₂) 85–95%; Aluminum Oxide (Al₂O₃) 5–10%; Trace water content
CAS Number: Silica Gel – 112926-00-8, Aluminum Oxide – 1344-28-1
Impurities: Possible trace minerals inherent to manufacturing, typically under 1%
Inhalation: Move to fresh air if breathing becomes difficult; seek medical attention for persistent symptoms
Skin Contact: Wash with soap and plenty of water; apply moisturizer if skin feels dry or irritated
Eye Contact: Immediately flush with water for at least 15 minutes; obtain medical attention if redness or irritation continues
Ingestion: Rinse mouth with water; do not induce vomiting; seek medical help if discomfort remains
Suitable Extinguishing Media: Use agents suitable for surrounding fire; product does not burn
Specific Hazards: Product is non-flammable and non-combustible; exposure to intense heat may burst closed containers
Protective Equipment: Firefighters should wear standard turnout gear and self-contained breathing apparatus
Decomposition Products: No hazardous decomposition products at standard temperatures; avoid breathing any dust generated during a fire
Personal Precautions: Use dust mask and safety goggles; avoid breathing dust
Clean-Up Methods: Scoop or vacuum without generating dust; transfer to dry, sealable containers for reuse or disposal
Environmental Precautions: Prevent product from entering drains or waterways as a fine particulate; avoid dispersal by wind
Handling: Use in well-ventilated areas with controls to prevent dust buildup; minimize rough handling to reduce breakage and dust
Storage Conditions: Keep in tightly closed containers; store dry, away from acids and alkalis
Incompatibilities: Avoid contact with hydrofluoric acid and strong bases; reacts exothermically with moisture if strongly heated
Exposure Limits: OSHA PEL for respirable fraction of nuisance dust: 5 mg/m³ (8-hour TWA)
Engineering Controls: Local exhaust recommended; keep dust levels as low as possible
Personal Protective Equipment: Safety glasses or goggles for bulk handling; dust respirator if airborne concentrations exceed guidelines; gloves for extended contact
Hygiene Measures: Wash hands after handling; do not eat, drink or smoke in handling areas
Appearance: White to off-white granules or spherical beads
Odor: Odorless
pH (in suspension): 6–8
Solubility: Insoluble in water and most solvents
Melting Point: Over 1600°C
Boiling Point: Not applicable
Bulk Density: 0.7–0.9 g/cm³
Vapor Pressure: Negligible
Flash Point: Non-combustible
Chemical Stability: Stable under normal conditions of use and storage
Conditions to Avoid: Contact with hydrofluoric acid and hot, concentrated alkalis
Hazardous Reactions: Contact with strong acids and bases leads to decomposition; generates heat if mixed with water in bulk at high temperatures
Hazardous Decomposition Products: None expected under regular usage
Acute Toxicity: No known acute toxic effects by oral, dermal, or inhalation routes
Inhalation: Prolonged exposure can dry out mucous membranes, trigger cough or throat discomfort
Skin Contact: Repeated or extended exposure causes dryness or mild irritation
Eye Contact: May cause temporary irritation and redness
Chronic Effects: Inhaling dust over extended periods might lead to respiratory irritation; no evidence of carcinogenicity
Environmental Fate: Sinks in water; not expected to harm aquatic life in bulk form
Persistence and Degradability: Chemically stable; remains in solid state without degrading
Bioaccumulation Potential: None; insoluble and inert in biological systems
Mobility in Soil: Low; primarily settles and integrates into soil matrix
Waste Methods: Dispose in accordance with local, state, or national regulations
Unused Product: Uncontaminated material may be reclaimed or disposed as non-hazardous industrial waste
Contaminated Packaging: Clean thoroughly before recycling or disposing; follow local protocols for silica-containing materials
UN Number: Not regulated
Transport Hazard Class: Not classified as hazardous for shipping
Proper Shipping Name: Non-hazardous, industrial desiccant (Silica Gel-Alumina Mix)
Packing Group: Not assigned
Environmental Hazards: Minimal; contain to prevent dust generation in transport
Labeling Requirements: No hazard classification required under GHS or OSHA standards
Inventory Listings: TSCA (USA), EINECS (Europe), DSL (Canada): Listed for all ingredients
Other Regulation: Not subject to special handling or restrictions in most jurisdictions; refer to country-specific provisions as standards may differ for workplace exposure
