Product Name: Erythorbic Acid
Synonyms: D-Isoascorbic Acid, E315
Chemical Formula: C6H8O6
Molecular Weight: 176.12 g/mol
Recommended Use: Food antioxidant, preservative in pharmaceuticals and processed foods
Manufacturer: Refer to your supplier for specific manufacturer details
Contact Information: Emergency phone number and address should come from supplier’s product label or documents
Classification: Not classified as hazardous under most GHS or OSHA regulations
Signal Word: None assigned for typical quantities
Hazard Statements: May cause mild skin or eye irritation in sensitive individuals
Precautionary Statements: Avoid prolonged or repeated contact with eyes and skin; prevent generating dust clouds
Main Health Effects: Inhalation of dust may cause respiratory irritation; accidental ingestion of large amounts may lead to gastrointestinal distress
Chemical Name: Erythorbic Acid
Common Name: D-Isoascorbic Acid
CAS Number: 89-65-6
Concentration: Greater than 99% by weight
Impurities: Contains only trace residual water and natural byproducts from manufacturing, if any
Inhalation: Move person to fresh air, monitor for breathing difficulty; seek medical advice if symptoms persist
Skin Contact: Remove contaminated clothing, wash skin gently with soap and water; medical attention rarely needed unless irritation persists
Eye Contact: Rinse cautiously with plenty of water for several minutes; keep eyes open and avoid rubbing
Ingestion: Rinse mouth thoroughly, drink water for dilution; seek medical advice in case of persistent symptoms or large ingestion
Suitable Extinguishing Media: Use water spray, foam, dry chemical or carbon dioxide for fires nearby; powder itself does not ignite easily
Unsuitable Media: Avoid high-pressure water jets that could spread dust
Specific Hazards: Fine dust may create explosion risk in confined areas, especially in combination with sparks or flames
Protective Equipment: Firefighters should use standard protective gear including self-contained breathing apparatus; avoid dust exposure during cleanup
Decomposition Products: Thermal decomposition may release carbon monoxide, carbon dioxide, and minor organic acids
Personal Precautions: Evacuate unnecessary personnel, use respiratory protection if dust levels are high
Environmental Precautions: Prevent entry to natural water sources, drains or soil to avoid minor local disruption
Methods for Cleanup: Scoop or sweep up powder gently to avoid dust generation, place in properly labeled containers for recovery or disposal; ventilate spill area
Handling: Avoid dust generation and inhalation, minimize contact with skin and eyes; use local ventilation if needed
Storage Conditions: Keep in tightly sealed containers, away from heat, moisture and oxidizing agents
Incompatible Materials: Store separated from strong oxidizers and alkaline substances; prevent mix with peroxides
Shelf Life: Stable for several years if kept dry and cool, but potency may decrease if exposed to air and light
Occupational Exposure Limits: No established OSHA or ACGIH limits for erythorbic acid
Engineering Controls: Local exhaust and general ventilation in processing areas
Personal Protection: Respiratory protection for dust in high concentrations; safety glasses or goggles; disposable gloves for frequent handling; traditional work clothing to minimize skin exposure
Hygiene Measures: Wash hands and face after handling, avoid eating or drinking near product
Appearance: White to light yellow crystalline powder
Odor: Odorless or faint acidic smell
Odor Threshold: Not noticed in normal concentrations
pH (1% solution): Ranges from 2.0 to 3.0
Melting Point: 168-172°C (334-342°F)
Boiling Point: Decomposes before boiling
Flash Point: Not applicable
Solubility: Soluble in water, sparingly soluble in alcohols
Vapor Pressure: Not measurable under normal conditions
Density: 1.65 g/cm³
Bulk Density: Varies from 0.5 to 0.7 g/cm³ depending on granule size
Partition Coefficient: Log Kow -2.8, considered non-bioaccumulative
Auto-ignition Temp: Not prone to self-ignition under typical storage conditions
Chemical Stability: Stable under normal ambient conditions, but oxidizes slowly in air
Hazardous Reactions: May react with strong oxidizers, alkalis and certain metals; avoid high humidity
Decomposition: Exposed to excessive heat or light, it forms degradation products such as dehydroerythorbic acid and traces of carbon oxides
Acute Toxicity: LD50 (oral, rat) typically above 5000 mg/kg, considered very low toxicity
Skin Irritation: Mild, if any, in most individuals
Eye Irritation: May cause transient redness or discomfort
Inhalation: Dust may irritate respiratory system in sensitive individuals
Sensitization: No known cases of allergic sensitization
Chronic Effects: No recognized hazards with usual handling; not associated with carcinogenicity, mutagenicity or reproductive toxicity
Aquatic Toxicity: Not expected to pose significant risk; LC50 (fish) above 100 mg/L
Persistence and Degradability: Degrades rapidly, both biologically and through natural oxidative processes
Bioaccumulation: Low potential; does not accumulate in organisms
Ecological Mobility: Water-soluble and highly mobile in natural water systems
Other Adverse Effects: No ozone depletion or global warming relevance; not toxic to most plants or animals in trace amounts
Waste Disposal Methods: Can often be handled as non-hazardous chemical waste; dispose in accordance with local, regional, and national laws
Container Disposal: Rinse thoroughly, recycle or recover material if feasible; follow best practices to prevent environmental release
Special Precautions: Avoid uncontrolled waste dumping or burning in open air; prefer incineration or landfill managed by licensed contractors
UN Number: Not regulated as hazardous for most modes of transport
Proper Shipping Name: Erythorbic Acid
Transport Hazard Class: Not classified
Packing Group: Not regulated
Marine Pollutant: Not considered a marine pollutant
Special Transport Precautions: Keep dry, secure heavy containers to prevent shifting, and label properly when bulk-shipping
TSCA Inventory: Listed
FDA Status: Approved as a food additive/preservative in many countries
