Health Hazards: Inhalation of dust may irritate airway, skin contact can cause mild irritation, ingestion at industrial scale requires medical attention if symptoms appear
Environmental Hazards: Low environmental impact, biodegradable, care needed to avoid significant releases
Label Elements: No pictogram or signal word necessary; precautionary statements focus on spills and dust control
Chemical Name: Propylene Glycol Alginate
Common Name: PGA
Content: >90% by weight
Impurities: Minimal; small traces of water, salts, and minor natural residues
Additives: No hazardous additives present
Inhalation: Move individual to fresh air; seek medical attention for persistent symptoms such as coughing or shortness of breath
Skin Contact: Wash exposed area with plenty of water and soap; remove contaminated clothing
Eye Contact: Rinse eyes immediately with plenty of water for several minutes, lift upper and lower eyelids; consult a physician in case of irritation
Ingestion: Rinse mouth, seek medical advice if large quantity swallowed or discomfort arises; do not induce vomiting unless instructed by medical professionals
Important Symptoms: Symptoms include mild irritation, redness of skin or eyes, and possible nausea upon accidental ingestion
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, carbon dioxide
Unsuitable Extinguishing Media: Direct high pressure water may scatter dust
Special Hazards: During combustion, product may release carbon oxides and small amounts of irritating fumes
Protective Equipment: Firefighters should wear standard protective equipment including self-contained breathing apparatus
Specific Methods: Remove containers from fire area if possible and safe; prevent firewater contamination of environment
Personal Precautions: Avoid creating dust clouds, ventilate affected area, wear protective gear to prevent contact
Environmental Precautions: Prevent spillage from entering drains, watercourses, or soil to limit ecological spread
Cleanup Methods: Sweep up and collect product into suitable containers for reuse or disposal, avoid dry sweeping that raises dust; wash residual material away with water
Precautions for Safe Handling: Take measures to minimize dust formation, store in tightly sealed containers, use in well-ventilated areas, avoid contact with eyes and prolonged contact with skin
Hygiene Practices: Wash hands and face after handling; do not eat, drink, or smoke in storage or use areas
Conditions for Safe Storage: Store at ambient temperature, away from direct sunlight, strong oxidizers, and sources of ignition; containers should be kept dry to avoid clumping and degradation
Incompatible Materials: Avoid strong acids, oxidizing agents, and unapproved chemicals
Exposure Limits: No occupational exposure limits established for propylene glycol alginate
Engineering Controls: Provide adequate mechanical ventilation, local exhaust if dusting occurs
Personal Protective Equipment: Protective gloves, safety glasses or goggles, dust mask (P2 or N95 standard) in dusty conditions, lab coat or coveralls
General Protective and Hygienic Measures: Remove contaminated clothing, avoid inhaling or ingesting dust, wash hands thoroughly after use; use eye wash stations and emergency showers if possible
Appearance: Off-white to yellowish powder
Odor: Almost odorless, faintly sweet
pH (1% solution): 3.0–4.5
Melting Point: Decomposes before melting
Boiling Point: Not applicable
Flash Point: Not flammable under normal conditions
Solubility: Dispersible in cold and hot water forming viscous solutions, insoluble in ethanol or oil
Relative Density: 1.50–1.60 g/cm³
Partition Coefficient (Log Kow): Not determined
Auto-Ignition Temperature: No data available
Decomposition Temperature: Above 150°C; thermal decomposition yields carbon monoxide, carbon dioxide
Chemical Stability: Stable under recommended storage and handling conditions
Reactivity: Chemically stable, not reactive with water in solution at normal storage
Possible Hazardous Reactions: May react with strong oxidizers causing decomposition
Conditions to Avoid: Excessive heat, moisture, and direct sunlight accelerate breakdown
Incompatible Materials: Strong acids, oxidizing agents, highly alkaline substances
Hazardous Decomposition Products: Carbon monoxide, carbon dioxide, small quantities of organic acids on thermal breakdown
Acute Toxicity: Low toxicity; high doses (animal studies) may cause digestive discomfort without organ damage
Skin Corrosion/Irritation: Mild, temporary irritation possible after prolonged or repeated contact
Serious Eye Damage/Irritation: Dust exposure may cause mild, reversible eye irritation
Respiratory Sensitization: Inhalation of dust may irritate respiratory tract; no known sensitization reported
Carcinogenicity: No evidence from studies linking to cancer or mutagenic effects
Chronic Effects: Repeated exposure unlikely to cause severe health effects in typical workplace environments
Ingestion: Expected to be safe in intended food uses; aspirating large amounts at workplace may require medical evaluation
Aquatic Toxicity: Low toxicity for aquatic organisms; rapidly biodegradable
Persistence and Degradability: Product is biodegradable; broken down by soil and water bacteria within weeks
Bioaccumulative Potential: Unlikely to bioaccumulate due to high solubility and biodegradability
Mobility in Soil: Mobile in water, low retention in soil matrix
Other Harmful Effects: Large spills may cause oxygen depletion in water; general absence of long-term impact on environment
Waste Disposal: Dispose of in accordance with local, regional, and national regulations; can usually be landfilled or incinerated in approved facilities
Container Disposal: Empty containers should be thoroughly cleaned or recycled if possible; avoid reusing containers for non-approved substances
Special Precautions: Prevent high concentrations from entering watercourses or sewers to minimize environmental load
UN Number: Not regulated as hazardous for transport
Proper Shipping Name: Not classified as dangerous goods
Transport Hazard Class(es): None assigned
Packing Group: No special packing required
Environmental Hazards: Not a marine pollutant; ship in sealed containers to avoid moisture uptake
Transport Precautions: Secure to prevent shifting, keep dry, avoid rough handling
Relevant Regulations: Food Chemicals Codex, FAO/WHO standards, FDA 21 CFR 172.858 (USA), EU E-numbers (E405), Chinese GB 2760
Workplace Exposure Guidance: Not specifically listed; general dust standards apply
Environmental Regulations: Compliant with Clean Water Act, not subject to special reporting or restriction
Labeling Requirements: No hazard labeling needed under GHS or OSHA; recommended to list product name, manufacturer, and batch code
