Additives: No preservatives or synthetic additives present in most grades used for food
Impurities: Agricultural byproducts may appear in negligible quantities
Inhalation: Move to fresh air, seek medical attention if coughing or shortness of breath continues, rinse mouth and nose with water
Skin Contact: Wash with soap and plenty of water, remove contaminated clothing, seek medical advice in case of irritation
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present, continue rinsing until irritation subsides
Ingestion: Rinse mouth with water, drink water to dilute any ingested powder, medical attention not usually required unless symptoms persist
Information for Doctor: No specific antidote, treat symptomatically and provide supportive measures
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide; avoid high-pressure water streams
Hazardous Combustion Products: Emits carbon monoxide, carbon dioxide, and possibly small amounts of nitrogen oxides when burned
Specific Hazards: Dust may form explosive mixtures in air, avoid spreading dust when fighting fire
Advice for Firefighters: Wear self-contained breathing apparatus and protective clothing to prevent exposure to combustion fumes
Fire and Explosion Data: Fine airborne dust can be ignited by heat, flame, or static discharge above lower explosive limit
Firefighting Procedures: Contain runoff, extinguish from upwind if possible, and reduce movement to prevent dust clouds
Personal Precautions: Use dust masks or respirators to avoid inhaling airborne particles, wear gloves and goggles for personal protection
Environmental Precautions: Prevent dispersal into drains and large bodies of water to reduce slip hazards and avoid bacterial growth
Spill Cleanup Methods: Sweep or vacuum up the material, avoid creating dust clouds using water mist or local exhaust; transfer to labeled containers for disposal
Emergency Procedures: Isolate spill area and ventilate, clean immediately to minimize residue
Protective Equipment: NIOSH-approved mask, safety goggles, and chemical-resistant gloves recommended during cleanup
Handling: Utilize local dust extraction when working with large quantities, avoid creating airborne dust, handle with clean, dry tools only
Safe Practices: Wash hands thoroughly before eating, drinking, or smoking after handling, keep away from ignitable sources
Storage Conditions: Store in tightly closed containers in a cool, dry, and well-ventilated area, protect from moisture and direct sunlight
Incompatible Materials: Do not store near oxidizers or strong acids
Storage Life: Product remains stable for up to 24 months under ideal conditions
Packing Materials: Use sealed, food-grade, or chemical-resistant packaging to prevent moisture ingress
Exposure Limits: No OSHA PEL or ACGIH TLV established for Guar Gum; industry guidance suggests keeping dust below 10 mg/m³ (inhalable fraction)
Engineering Controls: Employ local exhaust ventilation and dust extraction systems
Personal Protective Equipment: Dust mask or respirator (P2/P3), chemical-resistant gloves, safety goggles or full-face shield for operators
Hygiene Measures: Change contaminated clothing, wash hands and exposed skin after use
Environmental Controls: Prevent dust accumulation on floors and surfaces to reduce risk of airborne particles
Appearance: Off-white to pale yellow, fine powder or granules
Odor: Neutral, faint earthy smell
pH (1% solution): 5.0 to 7.0
Melting Point: Not applicable; decomposes before melting
Boiling Point: Not applicable
Solubility: Highly soluble in cold water, forms a viscous solution
Moisture Content: Below 10% by weight
Bulk Density: 0.6–0.8 g/cm³

Vapor Pressure: Not significant
Evaporation Rate: Not relevant
Chemical Stability: Stable under advised storage and handling procedures
Conditions to Avoid: Avoid moisture, heat sources, open flames, and static electricity discharge
Reactive Materials: Strong oxidizers and acids, which may break down gum polymers
Decomposition Products: Produces carbon monoxide, carbon dioxide, nitrogen oxides on thermal decomposition
Hazardous Polymerization: Will not occur under normal use
Incompatibility: Strong acid and alkali can degrade the product
Acute Toxicity: LD50 (rat, oral) exceeds 5000 mg/kg; product demonstrates very low toxicity
Chronic Effects: No evidence of carcinogenic, mutagenic, or teratogenic effects from long-term exposure
Routes of Exposure: Inhalation, ingestion, skin, and eye contact, with primary concern being dust inhalation
Symptoms: Temporary respiratory irritation, coughing, sneezing, or mild skin dryness possible
Target Organs: Lungs and eyes in sensitive individuals
Irritation Data: Mild, self-limiting irritation to skin or mucous membrane in sensitive people
Sensitization: Rare, but occupational exposure may elevate risk of allergic reaction, particularly in asthmatics
Medical Conditions Aggravated: Pre-existing lung or breathing disorders, such as asthma
Aquatic Toxicity: Not acutely toxic; may contribute to excessive nutrient loads in waterways if released in large quantities
Biodegradability: Readily biodegradable by soil and aquatic microorganisms
Persistence: Rapid breakdown under normal environmental conditions limits accumulation
Bioaccumulation: Unlikely due to high water solubility and rapid degradation
Mobility: Dissolves and disperses easily in water
Soil Impact: Excessive release can temporarily alter soil structure by increasing water retention
Effect on Wildlife: Low risk; but ingestion of dust in large quantities could physically obstruct animal digestive tracts
