Product Name: Oxidized Starch
Chemical Formula: Variable, based on starch base and degree of oxidation
CAS Number: 9045-28-7
Recommended Use: Application ranges from paper manufacturing and textile sizing to food additives and adhesives.
Manufacturer Details: Supplier details required for traceability, including emergency contact information to be provided on the product's packaging or by request.
Other Names: Hypochlorite-oxidized starch, modified starch
Hazard Classification: Not classified as hazardous under GHS for most commercial uses, but dust formation creates respiratory and explosion hazards.
Physical Hazards: Fine powders can form combustible dust-air mixtures increasing the risk of flash fire or explosion if dispersed.
Health Hazards: Inhalation of dust may irritate respiratory tract, eyes, and skin; no known long-term systemic health effects.
Environmental Hazards: Not expected to present significant hazards to aquatic or terrestrial life; large spills may affect chemical oxygen demand in water.
Warning Symbols: No pictogram required, but “dust hazard” signage is appropriate.
Chemical Composition: Major portion consists of partially oxidized polysaccharides derived from natural maize, potato, or tapioca starch.
Impurities: Trace residues of sodium hypochlorite or other oxidizers below regulatory thresholds; moisture typically below 15%.
Stabilizers: No hazardous additives or stabilizers present.
General Advice: Move affected person from exposure source. Medical attention recommended in case of persistent symptoms.
Inhalation: Remove to fresh air if vapor or dust causes symptoms; use saline eye/nose wash if irritation develops.
Eye Contact: Rinse immediately with plenty of water for at least 15 minutes. Avoid rubbing. Seek medical advice if irritation continues.
Skin Contact: Wash area with soap and water. Remove contaminated clothing and wash before reuse.
Ingestion: Give water to drink, never attempt to induce vomiting unless under medical guidance; medical evaluation recommended for larger amounts.
Note to Physicians: Symptomatic and supportive care only.
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide. Cool containers exposed to flames with water mist.
Special Hazards: Dust clouds can ignite. Decomposition produces vapors of carbon monoxide, carbon dioxide, and small amounts of irritating fumes.
Protective Equipment: Firefighters need self-contained breathing apparatus and standard protective gear.
Explosion Sensitivity: Fine powders may ignite and explode if exposed to a flame or spark.
Personal Precautions: Wear suitable respiratory protection and gloves to prevent dust inhalation and skin contact.
Environmental Precautions: Prevent uncontrolled discharge into water bodies, sewers, or public drainage.
Methods for Clean-Up: Sweep up gently without dispersing dust. Use antistatic tools and collect material in tightly sealed, labeled containers for proper recovery or disposal.
Reference to Other Sections: Contaminated material to be disposed of per local regulations.
Safe Handling Advice: Avoid generating dust during manufacturing and application. Ground and bond transfer equipment to prevent static sparks. Limit ignition sources in the area.
Storage Conditions: Store in original, tightly closed packaging, away from heat, open flames, strong oxidizing agents, and sources of moisture. Prefer cool, dry, well-ventilated places.
Incompatibilities: Oxidizers, acids, strong reducing agents.
Hygiene Measures: Regularly clean work clothes, wash hands before eating or drinking.
Engineering Controls: Utilize local exhaust or general ventilation to reduce airborne dust. Automated material handling reduces exposure risk.
Workplace Exposure Limits: No specific OEL set for oxidized starch; use nuisance dust guideline: 10 mg/m³ inhalable, 3 mg/m³ respirable particulate (OSHA/ACGIH recommendations).
Personal Protective Equipment (PPE): Use dust-proof goggles and gloves for routine work. Dust mask or respirator suitable for particulates during powder handling. Closed work clothes and, in case of spillage, protective overalls.
Environmental Exposure Controls: Waste dust should not enter drains.
Appearance: White to off-white powder or fine granules
Odor: Odorless or faint natural starch smell
pH Solution: 4.5–7.5 (10% aqueous suspension)
Boiling/Melting Point: Decomposes without melting; no defined boiling point.
Solubility: Insoluble in cold water, disperses in warm water to form colloidal solutions.
Explosion Properties: Dust can explode when airborne and ignited.
Other Data: Bulk density and moisture content are batch-dependent.
Chemical Stability: Stable under normal processing, handling, and storage conditions.
Reactivity: Incompatible with strong oxidizing agents. High temperatures can decompose material.
Hazardous Decomposition: Mainly carbon oxides and low concentrations of irritant vapors.
Polymerization: Does not occur.
Acute Toxicity: Very low toxicity if swallowed, inhaled, or contacted with skin under normal conditions.
Skin and Eye Contact: Dust can cause mild irritation.
Chronic Effects: No evidence of chronic toxicity found in typical workplace scenarios.
Inhalation Effects: Respiratory discomfort possible with prolonged or excessive dust exposure.
Carcinogenicity and Mutagenicity: No components classified as mutagenic, carcinogenic, or reprotoxic.
Known Allergies: No allergenic effects reported in non-sensitized people.
Environmental Toxicity: Degrades into simple organic substances; no significant hazard to aquatic or terrestrial organisms in diluted concentrations.
Persistence and Degradability: Readily biodegradable; breaks down under natural environmental conditions.
Bioaccumulation: Does not bioaccumulate.
Mobility: Solid forms tend to settle; water suspensions will disperse and degrade naturally.
Effect On Sewage: Large quantities may lead to increased load in wastewater treatment plants but biodegradable under aerobic conditions.
Product Disposal: Recycle, compost, or landfill in accordance with local, national, or regional regulations.
Contaminated Packaging: Empty packaging should be cleaned or disposed of as per solid waste regulations.
Special Precautions: Avoid dust formation and uncontrolled release to sewers. For bulk disposal, consult local regulatory agencies.
Regulatory Status: Not categorized as a dangerous good for transport under most global regulations (IMDG, IATA, ADR/RID).
Packaging Requirements: Use sealed bags, fiber drums, or moisture-proof containers.
Shipping Hazards: Protect from water, ignition sources, and strong oxidants during transportation.
UN Number: Not assigned.
Special Precautions: Prevent damage or moisture to packages to reduce dust-related risks.
GHS Labeling: Not required for most finished products but dust hazard management remains important.
Inventory Listings: Registered or notified in many national inventories (TSCA, EINECS, DSL, ENCS, AICS).
OSHA Compliance: Compliant with general industry and chemical safety standards.
Community Right-To-Know: Not subject to reporting under SARA Title III or similar frameworks.
