Precautionary Statements: Avoid breathing dust, use appropriate ventilation during bulk handling, avoid eye contact
Chemical Name: Synthetic Amorphous Silica
CAS Number: 112926-00-8
Content: Greater than 99% silica by weight; impurities below 0.5% such as trace salts or water
Physical Form: Fine white powder or granulated material; granularity depends on application
Eye Contact: Rinse with plenty of water for several minutes, do not rub, seek medical attention if irritation persists
Skin Contact: Remove contaminated clothing, rinse skin under running water, gentle soap can be used
Inhalation: Move affected person to fresh air, medical attention for prolonged discomfort
Ingestion: Minimal risk; rinse mouth thoroughly and drink water, seek help if adverse symptoms develop
Extinguishing Media: Product does not burn; use water spray, foam, dry chemical or carbon dioxide on adjacent materials
Specific Hazards: Non-flammable, non-combustible; does not support fire or release dangerous gases in fire
Protective Equipment: Standard fire-fighting gear suffices, product does not pose unusual hazards during a fire
Advice for Firefighters: Keep containers cool, avoid generating dust during firefighting actions
Personal Precautions: Use dust mask or respirator, gloves, and safety goggles if handling large quantities
Spill Cleanup Methods: Sweep or vacuum spilled material, avoid dry sweeping to limit dust; collect in labeled containers
Environmental Precautions: Prevent from entering water systems or drains in bulk amounts; not harmful to aquatic life in small amounts typical for consumer products
Disposal: Gather material for disposal in accordance with local regulations governing non-hazardous industrial solid waste
Safe Handling: Minimize dust formation, use in well-ventilated areas, keep containers sealed when not in use
Hygiene Measures: Wash hands and exposed skin after handling, do not eat or smoke during use
Storage Conditions: Store in a cool, dry, well-ventilated area, away from strong acids or bases
Incompatibility: Strong acids, hydrofluoric acid, strong oxidizers can react with silica
Exposure Limits: OSHA PEL for nuisance dust is 15 mg/m³ (total), 5 mg/m³ (respirable)
Engineering Controls: Local exhaust recommended for processing or large-scale use
Personal Protection: Dust mask, safety glasses, gloves recommended for industrial handling
General Protection: No special requirements in normal consumer use as an ingredient in toothpaste
Appearance: White, odorless powder or granular solid
Odor: None
Odor Threshold: Not applicable
pH (10% solution): Around 7 (neutral)
Melting Point: Greater than 1,600°C
Boiling Point: Not applicable (solid, decomposes at high temperature)
Flash Point: Not applicable
Solubility: Practically insoluble in water and organic solvents
Vapor Pressure: Not applicable
Chemical Stability: Stable under recommended conditions
Reactivity: Unreactive under normal conditions
Hazardous Reactions: None reported under standard storage and use
Conditions to Avoid: Avoid contact with strong acids and hydrofluoric acid
Decomposition Products: None under standard conditions; no toxic gases released upon decomposition in normal use
Acute Toxicity: LD50 (oral, rat) > 5,000 mg/kg (essentially non-toxic)
Chronic Effects: No evidence of carcinogenicity for amorphous silica in oral care forms; crystalline silica poses a risk in industrial inhalation but is absent from oral care products
Irritation: Dust can cause mechanical irritation to eyes and respiratory tract
Other Risks: No sensitization, mutagenicity or reproductive toxicity data connected to routine consumer exposure
Ecotoxicity: Not considered toxic to aquatic life at doses used in oral care
Persistence: Silica is a major component of sand, not biodegradable, remains as inert solid in the environment
Bioaccumulation: No evidence of accumulation in organisms
Environmental Fate: Remains in solid phase, incorporated into soils or sediment; no significant environmental risk in consumer quantities
Waste Disposal Methods: Dispose as non-hazardous solid waste based on local/regional/national regulations
Packing Material: Empty containers may be recycled or disposed according to regional guidelines
Precautions: Avoid dust generation during disposal, sweep up and contain as much as possible
Special Waste Codes: Not regulated as hazardous waste for disposal or transport
UN Number: Not classified as dangerous for transport
Proper Shipping Name: Not regulated
Hazard Class: Not assigned
Packing Group: Not assigned; store and transport in dry, sealed packaging
Additional Requirements: No special restrictions for land, sea, or air transport
Labeling: Not hazardous under GHS or EU CLP for the consumer use of oral care silica
Inventory Status: Listed on TSCA, EINECS, and other major chemical inventories
Specific Legislation: Safe for use in foods and oral care products within established guidelines, subject to FDA and EU Cosmetic Regulation compliance
Worker Safety: Industrial processes must comply with OSHA exposure limits and employee training requirements
Other Guidelines: No special labeling or restrictions for retail toothpaste and oral care product uses
