Material Safety Data Sheet (MSDS) – Liquid Glucose

Identification

Product name: Liquid Glucose
Chemical name: D-Glucose solution
CAS number: 8029-43-4
EC number: 232-436-4
Recommended use: Food additive, pharmaceutical ingredient, industrial applications
Manufacturer/Supplier: [Company Name]
Contact information: [Address, Telephone, Email]

Hazard Identification

GHS Classification: Product is not classified as hazardous under GHS conventions
Physical hazards: Non-flammable, no risk of explosion
Health hazards: Not considered toxic, prolonged skin or eye contact with concentrated solution may cause mild irritation
Environmental hazards: Does not present known significant ecological hazards in diluted quantities
Signal word: None required
Pictograms: None
Precautionary statements: Avoid direct ingestion in unsafe contexts, prevent prolonged contact with skin and eyes

Composition / Information on Ingredients

Main constituents: D-Glucose (approximately 80% w/w)
Water: 15–20% w/w
Other sugars: Contains minor fractions of maltose and higher saccharides
Impurities: Trace amounts of mineral ash, organics from processing
Nature: Substance qualifies as a non-toxic carbohydrate syrup

First Aid Measures

Inhalation: Move to fresh air if aerosolized syrup inhaled
Skin contact: Rinse skin with water to remove syrup, especially if sticky residue remains
Eye contact: Rinse eyes cautiously with water for several minutes, remove contact lenses if present, seek advice for persistent irritation
Ingestion: Rinse mouth with water, seek attention if large quantities cause gastrointestinal upset
Notes to physician: Symptomatic treatment, no specific antidote required, glycolysis metabolism expected for glucose

Fire-Fighting Measures

Suitable extinguishing media: Use water spray, foam, carbon dioxide, or dry powder suitable for surrounding fire material
Unsuitable extinguishing media: No known limitations
Fire & explosion hazards: Liquid glucose will not support combustion, may produce small amounts of potentially irritating decomposition products at elevated temperatures
Protective gear: Standard protective equipment for chemical fires, including self-contained breathing apparatus
Advice for firefighters: Avoid exposure to decomposition fumes

Accidental Release Measures

Personal precautions: Wear gloves, goggles, and shoes with slip-resisting soles due to syrup’s sticky nature
Environmental precautions: Prevent uncontrolled release into municipal waterways in large quantities to avoid high biological oxygen demand
Methods for cleaning up: Contain the spill with absorbent materials like sand or inert pads, wash residues away with water after collecting syrup, dispose in accordance with regulations

Handling and Storage

Handling: Keep containers tightly closed to avoid spillage and microbial contamination, avoid handling with dirty or wet hands to prevent product spoilage
Storage: Store in cool, dry areas, avoid prolonged exposure to direct sunlight, maintain at temperatures below 35°C, use corrosion-resistant containers; keep away from oxidizing agents
Safe transferring steps: Clean equipment before and after use, prevent cross-contamination with allergens

Exposure Controls and Personal Protection

Exposure limits: No occupational exposure limits for liquid glucose set by OSHA, ACGIH, or similar standards
Engineering controls: Maintain adequate general ventilation, use mechanical stirring in industrial settings to prevent surface drying and dust formation from crystallization
Personal protection: Gloves and safety goggles during transfer or cleanup, no respirator needed for normal operations, lab coats and closed footwear for splash protection
Hygiene measures: Wash thoroughly after handling, do not eat, drink, or smoke during use

Physical and Chemical Properties

Appearance: Clear, colorless to pale yellow, highly viscous syrup
Odor: Odorless or faintly sweet
pH: 4.0–6.5 (20% solution)
Melting/Freezing point: -30°C (approximate, due to high sugar content)
Boiling point: Above 100°C, typically does not boil in conventional use
Flash point: Not applicable
Solubility: Miscible with water, very high solubility
Density: 1.4–1.5 g/cm³ at 20°C
Viscosity: Highly viscous, flow may be slow at low temperatures
Decomposition temperature: Degrades above 160°C, caramelization occurs

Stability and Reactivity

Chemical stability: Stable under recommended storage conditions, hygroscopic, absorbs moisture from air
Incompatible substances: Strong oxidizers, strong acids, bases may cause hydrolysis or caramelization
Hazardous decomposition products: Burning can produce carbon oxides, other organic volatiles
Polymerization risk: None
Reactivity: Low reactivity under normal physical and chemical conditions

Toxicological Information

Acute toxicity: Non-toxic to humans, excessive ingestion can raise blood sugar
Skin irritation: May cause mild irritation (redness, stickiness) if not washed off
Eye irritation: Transient mild redness possible on contact
Sensitization: No allergic sensitization known for pure liquid glucose
Repeated exposure: Long-term exposure not associated with specific organ toxicity outside of dietary overconsumption
Carcinogenicity: Not classified as carcinogen by IARC, NTP, or OSHA

Ecological Information

Aquatic toxicity: Not expected to be toxic, but large releases may lead to oxygen depletion in water due to microbial activity
Persistence and degradability: Readily biodegradable through microbial metabolism
Bioaccumulative potential: Does not bioaccumulate
Mobility in soil: High water solubility means it disperses easily in moist soil, broken down by microbes
Other adverse effects: Large spills in natural water can disrupt aquatic life by rapid microbial oxygen consumption

Disposal Considerations

Waste treatment methods: Dispose syrup through controlled industrial wastewater systems, municipal landfill, or biotreatment processes
Disposal of containers: Clean containers before recycling or disposal, avoid introducing to environment without treatment
Regulatory waste status: Not classified as hazardous waste per RCRA or similar regulations if uncontaminated
Precautions: Avoid uncontrolled release into sewage or open ground to prevent ecological impact

Transport Information

UN Number: Not regulated as a dangerous good
Transport hazard class: Non-hazardous material under ADR, RID, IATA, IMDG
Packing group: No restrictions
Special precautions for transport: Ensure secure sealing to prevent sticky leaks, avoid extreme heat during transport, clearly label containers for handling
Transport in bulk: Use approved tanks for food substances to prevent contamination and syrup crystallization

Regulatory Information

Labeling requirements: No hazard labeling under WHMIS, OSHA, or EU regulations
Chemical inventory listing: Present on TSCA, EINECS, and other international chemical inventories
Food and drug status: Generally recognized as safe (GRAS) for intended food and pharmaceutical uses
Occupational health rules: Standard workplace hygiene and food safety standards apply
Environmental rules: Dispose of large volumes responsibly to avoid high biological oxygen demand in watercourses
