Substance Name: Inulin
Chemical Formula: C6nH10n+2O5n+1 (n ranges typically from 2 to 60)
Common Uses: Seen in food products as a dietary fiber, used to improve texture, and often serves as a sugar replacement. Commercial production usually draws from chicory root, agave, or Jerusalem artichoke.
Physical State: Fine, off-white powder with no strong scent.
Natural Origin: Extracted from various root vegetables and plants, especially chicory.
Industry Presence: Used in nutrition bars, cereals, snacks, and increasingly in pharmaceuticals for its prebiotic qualities.
Health Risks: Not considered toxic in regular dietary quantities, though large intakes can cause gastrointestinal discomfort, bloating, and flatulence.
Allergen Concerns: Rare, but individuals sensitive to ragweed and related plants might react due to cross-reactivity with chicory-derived inulin.
Flammability Risk: Dust can become combustible in heavy concentrations, presenting a fire and dust explosion hazard in manufacturing or large-scale storage.
Impact on Environment: Minimal hazard when released, as it breaks down naturally.
Pictograms and Signal Words: Not required since inulin does not carry substantial acute hazard under GHS classifications.
PPE Recommendations: Gloves and dust masks limit irritation, especially during bulk handling.
Main Ingredient: Inulin, purity often exceeding 90%, remaining portion may feature trace oligosaccharides.
Impurities: Tiny amounts of plant matter or mono- and disaccharides, depending on processing method. Chemical additives generally absent.
CAS Number for Inulin: 9005-80-5
Ingredient Source: Primarily chicory root, processed by hot water extraction, filtration, and drying. No synthetic chemicals involved in most food-grade inulin.
Inhalation Exposure: Move to fresh air, rinse mouth if irritation develops. Respiratory effects relate more to dust inhalation than to chemical reactivity.
Skin Contact: Rinse exposed area with water. Cases of irritation crop up rarely, normally after extended exposure or in individuals with sensitive skin.
Eye Contact: Direct dust contact requires flushing with running water for up to 15 minutes. Blink often and avoid rubbing the eyes.
Ingestion: No acute hazard; nausea and stomach upset may occur if large, unfamiliar amounts are swallowed.
Medical Attention: Persistent or unusual symptoms deserve professional evaluation.
Suitable Extinguishers: Use water spray, foam, or dry chemical extinguishers on fires involving inulin dust.
Explosion Potential: Heavy airborne dust increases the chance of an explosive combustion. Dust collection and ventilation systems help reduce the risk.
Combustion Products: Heating to decomposition may yield oxides of carbon.
Protective Equipment: Respirators and protective suits help shield from fumes and particles when fighting a dust-related fire.
Spill Response: Avoid raising dust clouds when cleaning spills. Use a vacuum with a HEPA filter or wet methods to collect bulk material.
Personal Protection: Gloves, goggles, and respiratory protection reduce risk.
Environmental Management: Prevent runoff into surface water. Clean up residue from hard floors and surfaces promptly.
Waste Handling: Dispose as solid non-hazardous waste if contaminated with other materials, or reuse if clean.
Packing Guidance: Store in sealed, moisture-proof containers. Contact with water clumps the powder, so desiccant packs make sense in humid rooms.
Temperature and Light: Cool, dry, and shaded conditions preserve inulin quality and limit degradation.
Handling Practices: Avoid strong stirring or shaking to minimize airborne dust. Workers should wear gloves and masks if often exposed.
Segregation: Keep away from oxidizing agents and moisture to prevent chemical breakdown and spoilage.
Exposure Limit: No established OSHA or ACGIH limits, but standard nuisance dust thresholds around 10 mg/m3 for total inhalable dust apply.
Engineering Controls: Effective local exhaust ventilation and dust extraction systems matter in production spaces.
Personal Protection: N95 dust masks, standard industrial gloves, and protective goggles can prevent nuisance symptoms.
General Hygiene: Routine hand washing and changing out of dusty work garments reduce carryover beyond the workplace.
Appearance: Powder, off-white, no prominent odor.
Solubility: Water-soluble at room temperature, forming a viscous solution.
Boiling/Melting Point: Decomposes before it melts; stable below 150°C.
pH (1% Solution): Typically around 5.5 to 7.5
Density: About 1.35 g/cm³
Particle Size: Fine powder, easily forms dust clouds if dispersed.
Chemical Stability: Stable in sealed packaging under dry, cool conditions.
Reactivity Risks: Sensitive to strong acids and bases; exposure may hydrolyze inulin to oligosaccharides and monosaccharides.
Incompatible Materials: Avoid mixing with oxidizers and strong alkalis.
Potential Byproducts: Thermal breakdown releases carbon oxides, but unlikely during common use.
Acute Toxicity: Low toxicity in humans. LD50 in animal studies far exceeds amounts plausible in food or supplement use.
Chronic Exposure: Regular, moderate intake serves as a prebiotic, but excessive consumption can result in digestive symptoms.
Allergenicity: Rare, but possible among individuals sensitive to related botanical families.
Special Populations: Infants, elderly, or those with gastrointestinal disorders may experience more pronounced effects from excess intake.
Environmental Fate: Degrades biologically and does not persist.
Aquatic Impact: High release into water may feed microbial blooms but typically dilutes rapidly.
Bioaccumulation: Does not build up in living tissue.
Wildlife Toxicity: Minimal hazard to animals and plants under typical environmental concentrations.
Waste Management: Inulin waste can be composted or landfilled with general biodegradable materials.
Packaging Disposal: Empty bags, containers, or liners should be disposed of with other non-hazardous commercial waste, or recycled if materials allow.
Special Precautions: No significant restrictions for most municipal or industrial waste streams.
Shipping Classification: Non-hazardous under road, rail, air, and sea regulations.
Proper Shipping Name: Not classified as dangerous goods.
Packing Recommendations: Moisture-resistant packaging, sealed tight, labeled with standard product name.
Handling in Transit: Transit vehicles should stay clean and dry.
Labelling: Not regulated as a hazardous substance in major jurisdictions including the US, EU, and Canada.
Ingredients Disclosure: Food grade inulin must declare source material on packaging, as required by food safety agencies.
Workplace Requirements: Dust control measures and basic PPE outlined in occupational safety standards for general organic dusts.
Permitted Use: Accepted as a food additive and supplement in most countries with established regulatory approvals.
