Impurities: Trace sulfuric acid, sodium salts, water
Additives: None intentionally added; manufacturer may report trace neutralizing agents
CAS Number: Specific to product; main component usually in range of C10-18
Inhalation: Move person to fresh air; seek medical attention if symptoms persist; provide oxygen if breathing difficult
Skin Contact: Remove contaminated clothing; immediately flush skin with plenty of water for at least 15 minutes; call a physician
Eye Contact: Rinse cautiously with water for at least 15 minutes, lifting eyelids; remove contact lenses if present and easy to do; seek immediate medical attention
Ingestion: Rinse mouth, do not induce vomiting; seek prompt medical attention; never give anything by mouth to an unconscious person
Suitable Extinguishing Media: Use dry chemical, CO2, or foam; water spray for cooling only—do not directly apply water to product
Specific Hazards: Produces toxic sulfur oxides and fumes under combustion; acids may react violently with metals
Protective Equipment: Firefighters should wear self-contained breathing apparatus (SCBA) and acid-resistant protective clothing
Special Procedures: Isolate area; avoid inhalation of vapors or decomposition products; evacuate downwind personnel
Personal Precautions: Evacuate unnecessary personnel; use chemical splash goggles, acid-resistant gloves, and protective clothing
Environmental Precautions: Prevent product from entering drains, surface water, or soil; contain spill with non-combustible absorbent material
Methods for Clean Up: Sweep up and place in appropriate chemical waste container for disposal; neutralize with sodium bicarbonate if available; ventilate area
Decontamination: Wash spill site thoroughly with water after material pickup is complete; monitor for continued release of fumes or residues
Handling Recommendations: Avoid dust formation; prevent contact with skin, eyes, clothing; do not eat or drink where material is handled; handle only with equipment suitable for corrosive materials
Storage Conditions: Store in tightly closed, corrosion-resistant containers; keep in cool, ventilated, dry area away from alkalies, chlorine, oxidizing agents, and water; keep only in original packaging
Incompatible Materials: Strong bases, oxidizing agents, metals (especially aluminum and zinc), concentrated chlorine
Occupational Exposure Limits: No established ACGIH or OSHA limits for Alkyl Sulphonic Acid specifically; follow nuisance dust limits—ACGIH TLV (Particulates Not Otherwise Classified): 10 mg/m³ TWA total
Engineering Controls: Provide local exhaust at points of emission; use closed process systems whenever possible; provide eyewash stations and safety showers
Personal Protection: Use chemical splash goggles, acid-resistant gloves, long-sleeved protective clothing; respirator equipment in situations of high dust or inadequate ventilation
Appearance: White to off-white solid, fine to granulated powder
Odor: Pungent, slightly sulfurous
pH (1% Solution): < 1 (strongly acidic)
Melting Point: Approximately 170–180°C (depends on alkyl chain length)
Boiling Point: Decomposes before boiling
Solubility: Readily soluble in water; forms acidic solutions
Vapor Pressure: Not measurable at ambient temperature
Density: Typically 1.3–1.5 g/cm³
Flash Point: Not flammable
Autoignition Temperature: Not applicable
Chemical Stability: Stable under recommended storage conditions; reacts with bases and certain metals
Hazardous Reactions: Vigorous reactions with strong bases, oxidizing agents, and reactive metals; generates heat and toxic gases with incompatible substances
Conditions to Avoid: Moisture, high temperatures, contact with metal containers not specially lined, mixing with incompatible chemicals
Decomposition Products: Sulfur oxides, carbon oxides, hydrocarbons if ignited
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Acute Toxicity: Corrosive; contact causes burns to skin, eyes, mucous membranes; inhalation of dust irritates respiratory tract; ingestion leads to gastrointestinal injury
Chronic Effects: Prolonged exposure can cause dermatitis and permanent eye damage
Carcinogenicity: Not listed as carcinogen by IARC, ACGIH, NTP, or OSHA; no evidence for mutagenicity or reproductive toxicity
Sensitization: Not reported for this material
Toxicity: Harmful to aquatic organisms; low LC50 for fish and aquatic invertebrates
Persistence and Degradability: Readily biodegradable under aerobic conditions; rapid metabolic breakdown in wastewater treatment
Bioaccumulative Potential: Low, as the compound hydrolyzes and is metabolized in the environment
Mobility in Soil: Expected to have moderate to high mobility in soil and water; may acidify local environments
Waste Disposal Methods: Classify as hazardous waste according to local regulations; dispose at approved chemical waste facility; neutralize with alkali under controlled conditions before disposal
Packaging Disposal: Triple rinse containers, puncture and discard according to chemical legislation; contaminated packaging must be handled as hazardous
Precautions: Never discharge into sewers or environment; consult local authorities for specific regulations
