Physical State: Fine white to off-white powder or granule, nearly odorless
Inhalation: Move affected person to fresh air, ensure they remain calm and breathe normally, seek medical attention for persistent irritation, rinse mouth if necessary
Skin Contact: Wash skin with water and mild soap; remove contaminated clothing and launder before reuse; if irritation develops, see a physician
Eye Contact: Immediately flush eyes with plenty of running water for at least 15 minutes, hold eyelids open, remove contact lenses, consult a doctor for prolonged discomfort
Ingestion: Rinse mouth with water, drink water to dilute, do not induce vomiting, obtain medical help if feeling unwell
Most Important Symptoms: Possible discomfort from dryness or mild irritation of mucous membranes; no known serious acute effects under normal use
Notes for Physician: Treat symptomatically, no antidote known, product has low toxicity
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide; avoid high-pressure water streams to minimize dust formation
Hazards from Combustion: Burning can produce carbon dioxide, carbon monoxide, minor phosphorus oxides
Protective Equipment: Wear respirator, protective clothing, eye protection, gloves if exposed to smoke or powders
Firefighting Advice: Cool nearby containers with water, evacuate area for large fires, prevent run-off from spreading to drains or natural water sources
Special Notes: Dust may be explosive if suspended in air and ignited; minimize dust cloud formation.
Personal Precautions: Use dust masks, protective eyewear, and gloves; avoid inhalation of dust and unnecessary contact with skin or eyes
Environmental Precautions: Prevent significant spillage from entering water systems, sewers, open drains
Methods for Clean-up: Gently sweep or vacuum up material and place in airtight labeled containers for disposal; use gentle, damp sweeping where possible to reduce airborne dust
Spill Size Response: For minor spills, sweep up immediately; for large releases, cordon off area, deploy appropriate dust controls, and notify authorities according to local regulations
Disposal: Collect waste in sealed drums, avoid flushing with water that may disperse material, dispose according to Section 13.
Handling Practices: Avoid dust creation, use with local exhaust ventilation where handling or transferring powders, wear appropriate PPE for eye and respiratory protection in bulk processing
Storage Recommendations: Store in cool, dry, well-ventilated places, keep containers tightly closed and protected from moisture; avoid mineral acids or strong oxidizers nearby
Incompatibilities: Strong acids, strong oxidizers, combustible dusts; do not mix with incompatible chemicals
General Hygiene: Wash hands thoroughly after handling, keep good housekeeping standards in work areas to prevent dust accumulation
Packaging Materials: Use moisture-resistant packaging, label containers clearly for identification and hazard prevention.
Exposure Limit Values: No specific regulatory limits for modified starch; use general nuisance dust standards—ACGIH TLV: 10 mg/m³ (inhalable) and 3 mg/m³ (respirable fraction)
Engineering Controls: Use local exhaust or general room ventilation to maintain airborne dust levels below exposure limits; implement process enclosure if needed
Personal Protective Equipment (PPE): Dust mask or particulate respirator (NIOSH-approved), protective eyewear (goggles or safety glasses), gloves for extended handling, washable workwear
Environmental Controls: Prevent run-off to public water systems, avoid dust dispersion by maintaining doors and windows closed during transfers
Other Precautions: Replace PPE regularly, maintain clean change areas for staff, provide emergency eye wash and shower stations in processing areas.
Appearance: White to off-white, fine powder or granule
Odor: Virtually odorless
Odor Threshold: Not established
pH: 5.0 – 8.0 in aqueous suspension
Melting/Freezing Point: Decomposes before melting; starch does not have a definite melting point
Boiling Point: Not applicable (solid material)
Flash Point: Not applicable; will only burn following ignition as dust cloud
Flammability: Dust may be combustible in air; risk of explosion with suspended dust
Vapor Pressure: Not relevant
Solubility: Swells in cold water, partially dispersible; better dispersibility in hot water
Partition Coefficient: Not applicable
Density: 0.5 – 0.7 g/cm³ (bulk density)
Explosive Properties: Dust may become explosive in confined areas with ignition source
Other Data: Slightly hygroscopic, absorbs atmospheric moisture if exposed
Chemical Stability: Stable in normal storage and handling conditions
Reactivity: Not reactive with most chemicals under ambient conditions
Conditions to Avoid: Elevated temperatures, sources of ignition or open flame, high humidity, accidental mixing with incompatible chemicals such as strong acids or oxidizers
Incompatible Materials: Mineral acids, chlorine, strong oxidizing agents
Hazardous Decomposition Products: Burning forms CO, CO₂, minor phosphate vapors
Hazardous Reactions: None expected during typical processing or industrial use
Acute Toxicity: No evidence of acute toxicity; oral LD50 in rats >2000 mg/kg, considered biologically inert
Skin Corrosion/Irritation: Non-irritant to skin, though mechanical dryness possible with repeated contact
Serious Eye Damage/Irritation: May cause discomfort from particulates, reversible on rinsing
Respiratory Sensitization: No indication of respiratory sensitization in animal or human data; dust may cause transient irritation

Carcinogenicity: Not listed by IARC, NTP, OSHA
Reproductive Toxicity: No adverse reproductive effects reported
Repeated Dose Toxicity: No observed adverse effects with subchronic or chronic dietary exposure
Other Health Effects: Ingestion in significant volumes may cause mild gastrointestinal discomfort; not expected at typical exposure levels.
Ecotoxicity: Not expected to be bioaccumulative, toxic to aquatic life, or persistent in the environment; derived from starches, readily biodegradable through normal microbiological processes
Persistence and Degradability: Readily biodegradable by soil and aquatic microorganisms
Bioaccumulation Potential: Low potential; hydrolyzed and assimilated rapidly in environmental conditions
Mobility in Soil: Limited mobility; solid particles settle quickly, degrade biologically
Other Adverse Effects: Substantial dumping may physically blanket water bodies by sedimentation, impacting oxygenation or visibility.
Waste Disposal Methods: Dispose through landfill according to local/national regulations for non-hazardous solid waste; avoid incineration unless controlled due to dust combustion characteristics
Product Disposal: Do not discharge into drains, sewers, or waterways; avoid contaminating natural water sources
Contaminated Packaging: Clean and recycle packaging where possible; otherwise, treat as solid waste
Regulatory Compliance: Always follow waste disposal laws and consult environmental authorities for proper protocol
