Chemical Name: Glyoxylic Acid Monohydrate Chemical Formula: C2H2O3·H2O Synonyms: Oxoacetic acid monohydrate Appearance: White to off-white crystalline powder or solid Odor: Slightly pungent, reminiscent of sour acids
Hazard Class: Classified as skin and eye irritant Label Elements: Irritant pictogram, exclamation mark symbol Main Hazards: Direct contact brings stinging to skin or eyes, heavy exposure means potential for respiratory irritation Chronic Hazards: Prolonged or repeated skin contact may lead to dermatitis, breathing dust can aggravate asthma Physical Hazards: Non-flammable, but reacts sharply with bases, oxidizers, and strong reducing agents
Component: Glyoxylic acid monohydrate CAS Number: 563-96-2 Concentration: 98%-100%
After Eye Contact: Flush cautiously with water for several minutes, remove contact lenses, rinse again, seek medical advice if irritation continues After Skin Contact: Wash with soap and plenty of water, remove contaminated clothing, persistent pain means visit a doctor After Inhalation: Move to fresh air, rest in a position easy for breathing, persistent symptoms call for medical attention If Ingested: Rinse mouth, do not induce vomiting, sip water, get medical help immediately
Extinguishing Media: Use water spray, carbon dioxide, dry chemical, or foam Fire Hazards: Does not burn easily, but may release irritating or corrosive fumes when heated Protective Actions: Firefighters should use self-contained breathing apparatus, avoid breathing fumes, keep containers cool by spraying with water
Personal Protection: Wear gloves, goggles, and dust mask Spill Handling: Ventilate area, avoid dust, clean up with damp cloth or absorbent, gather in closed container Environmental Precaution: Prevent product from entering drains or watercourses
Handling: Work in well-ventilated area, keep containers tightly closed, avoid splashes and dust, wash hands after use Storage: Store in cool, dry, ventilated place, keep away from bases, strong oxidizers, and incompatible substances, avoid moisture
Engineering Controls: Use local exhaust or ventilation to reduce airborne concentrations Protective Equipment: Safety goggles, lab coat, chemical-resistant gloves, dust mask especially for handling larger amounts Hygiene Measures: Do not eat, drink, or smoke when using, always wash hands after handling, launder contaminated clothing before reuse
Physical State: Solid crystals or powder Color: White to off-white Melting Point: About 98°C Boiling Point: Decomposes before boiling Solubility: Soluble in water, making it easy to handle for chemical processes Odor Threshold: Low pH (aqueous solution): Acidic
Chemical Stability: Stable under recommended storage and handling Reactivity: Vigorous with strong bases and oxidizers Decomposition: Heat or incompatible contact may create formic acid, carbon monoxide, or carbon dioxide Avoid: Strong alkalis, reductants, oxidizing agents
Acute Effects: Eye and skin irritation, respiratory tract discomfort on inhalation POTENTIAL Sensitization: People sensitive to organic acids might experience faster reactions Ingestion: Nausea, vomiting, and stomach pain possible from swallowing small amounts Long-Term Exposure: No reliable evidence points toward cancer risk, but chronic irritation possible
Environmental Impact: Toxic for aquatic life in large spills Bioaccumulation: Low, given water solubility helps break down in environment Mobility in Soil: High, moves fast through soil, so runoff and leaching is possible Large Release Impact: Alters water pH, disrupts aquatic habitats
Waste Disposal: Collect in sealed, labeled containers, send to licensed handler, do not dump in drains Ecosystem Care: Small spills can disrupt aquatic or sewage balance, treat before disposal Empty Containers: Rinse thoroughly before recycling or discarding
Transport Requirements: Keep sealed, avoid breakage, handle upright Hazard During Transit: Generated dust or leaks bring risk for carriers, secure packaging limits harm International Rules: Well-packed, labeled in line with chemical transport guidelines
Workplace Safety: Most public health agencies classify as hazardous for skin and eyes Right-to-Know: Information about this chemical’s hazards available through regulatory agencies Environmental Law: Reporting needed for spills leading to environmental contamination Worker Training: Proper education ensures fewer accidents and safer handling
