Chemical Name: D-Mannose
Common Names: Mannose, D-mannopyranose
Chemical Formula: C6H12O6
Physical Form: Fine powder or crystalline granules, colorless or white
Classification: Many have used D-Mannose in supplements and lab settings, knowing it does not meet the criteria for flammable, toxic, or dangerous goods under global chemical regulations.
Health Hazards: Ingestion or contact with skin doesn’t trigger the same risks seen with industrial chemicals, but dust may irritate eyes, respiratory tract, or skin—much like flour when you bake.
Label Elements: Typical warnings focus on mild irritation possible from airborne powder, not life-threatening danger.
Chemical: Pure D-Mannose
CAS Number: 3458-28-4
Concentration: Pure substance, unless blended for supplements
Inhalation: Fresh air clears up minor discomfort if someone breathes in dust from a leaky bag.
Skin Contact: Rinse with water if powder bothers skin; hand soap washes off sticky residue.
Eye Contact: Dust in the eye washes out with water, and any stinging fades quickly without special medicine.
Ingestion: No special response needed for accidental small exposure, but excess can cause digestive discomfort.
Suitable Extinguishing Media: Water, foam, dry chemical, or carbon dioxide work—the way you’d handle flour or sugar fires.
Specific Hazards: In rare cases, airborne powder ignites in the right conditions, much like cornstarch; storing away from flames makes sense.
Protective Equipment: Standard firefighting gear works, no need for chemical suits.
Personal Precautions: Dust mask and gloves protect sensitive people; not all need them, but experience shows some folks sneeze or itch.
Cleaning Up: Sweep or vacuum without stirring up more dust. Wet methods avoid clouding the air further. Washing down residual powder with water makes floors safe and slip-free.
Environmental Precautions: Spills rarely threaten the environment since D-Mannose dissolves in water and breaks down quickly, yet it shouldn’t get dumped straight into waterways in bulk.
Safe Handling: People handling it every day know not to shake bags or containers, cutting down on dust clouds. Clean, dry storage areas keep product quality up, and good sealing stops moisture from caking the powder.
Incompatibilities: Storing away from open flames, strong oxidizers, or acids keeps things low-risk.
Hygiene Measures: Clean hands before food or drink, and a dust mask or goggles help in busy mixing rooms.
Engineering Controls: Dust extraction or local ventilation in workrooms with frequent powder transfer, like supplement factories or pilot plants.
Personal Protection: Typical workplace practices use disposable masks, lightweight gloves, and maybe safety glasses. Repeated contact—rare for most—may need lotion or basic protective cream.
Occupational Exposure Limits: No formal threshold limits set in global standards, but industry experience supports dust minimization for comfort and productivity.
Appearance: White crystalline powder
Odor: Odorless
Melting Point: Around 132°C
Boiling Point: Not practical for this sugar; decomposes before boiling
Water Solubility: Rapidly dissolves in water
Density: Roughly 1.55 g/cm³
pH (solution): Neutral to slightly acidic when mixed with water
Stability: Stable in dry indoor conditions. Dampness encourages lumping, but does not cause toxic by-products.
Conditions to Avoid: Open flames or high heat; rapid airflow that stirs up dust; humid or wet areas.
Hazardous Decomposition Products: Sugars caramelize or char above their melting point, giving off simple organic fumes.
Acute Toxicity: Not considered dangerous in animal studies at everyday exposure levels. Large ingestion may cause bloating or mild digestive upset.
Skin and Eye Contact: Irritation can happen with repeated dust exposure, no systemic side effects seen.
Sensitization: Very rare; no common allergic reactions.
Long-Term Effects: Human data show no link to cancer or chronic organ damage when used in dietary applications.
Inhalation Risk: Only in high dust concentrations—control through standard workplace respiratory hygiene.
Biodegradability: Breaks down quickly in soil and water, used by microbes as a food source.
Bioaccumulation: Not expected; does not persist in food chains.
Aquatic Toxicity: Environmental experience with food factories shows minimal impact on aquatic life, only harm from large-scale raw powder releases.
Waste Handling: Add small amounts to compost or regular trash—D-Mannose fades into the environment much like table sugar.
Larger Quantities: Local waste regulations may require factory-scale disposals to head to landfill, away from surface water supplies.
Packaging: Recycle or dispose of empty bags according to local laws.
Hazard Classification: Not considered hazardous for road, air, or sea shipment.
Labeling Requirements: Marked as non-hazardous commodity; packaging must prevent leaks or dust during shipping.
Special Precautions: Keep away from food-sensitive cargo to prevent dust cross-contamination.
Chemical Inventories: Listed as generally regarded as safe (GRAS) for food or supplement use under the FDA, included in chemical inventories in the EU, US, and Asia.
Workplace Regulation: No strict controls, but workplace safety guidelines on dusts apply, reflecting the need for reasonable handling in bulk.
Labeling Rules: Product labeling for dietary supplements, not as a hazardous material—regulations set by food safety and consumer standards groups.
