Product Name: Di-Pentaerythritol 85-95% min. (Micronized)
Chemical Formula: C10H22O7
Synonyms: Dipenta, DPE, Dipentaerythritol
CAS Number: 126-58-9
Recommended Use: Used in alkyd resins, synthetic lubricants, plasticizers, flame retardants, and stabilizers
Manufacturer: (Insert manufacturer contact information here, including address and phone)
Emergency Contact: (Insert emergency number and local authority hotline)
Classification: Substance does not belong to categories considered hazardous under GHS standards. Dust formation can cause mechanical irritation to eyes, nose, and throat.
Main Hazards: Combustible dust risk, repeated inhalation in poorly ventilated areas can provoke respiratory discomfort. Handling large quantities in confined spaces raises the chance of explosive dust clouds.
Labelling Elements: No pictogram required, but attention to dust warnings is important; avoid inhaling micronized particles.
Other Hazards: May exacerbate pre-existing lung conditions over time; spilled powder is slippery and could lead to falls.
Chemical Name: Di-Pentaerythritol
Concentration: 85-95%
Impurities: Mono and tetra pentaerythritol (less than 10%)
Other Additives: None declared
Molecular Weight: 254.28 g/mol
Inhalation: Move affected person out of exposure; breathe fresh air; rinse mouth and drink water if symptoms crop up. Persistent breathing difficulty signals medical attention.
Skin Contact: Wash skin with soapy water, remove any contaminated clothing. For irritation that holds on, consult a doctor.
Eye Contact: Rinse eyes with plenty of water for several minutes while holding eyelids apart; if vision gets blurry or irritation lingers, see an eye specialist.
Ingestion: Rinse mouth, drink water to flush out the substance. If feeling unwell, get medical help.
Suitable Extinguishing Media: Water spray, dry powder, foam, or CO2, depending on what else is burning.
Unsuitable Media: Direct water jets may spread combustible dust.
Hazards from Combustion: Burning produces toxic smoke: carbon monoxide, carbon dioxide.
Protection for Firefighters: Full protective gear and self-contained breathing apparatus make sense in smoke-filled rooms.
Personal Precautions: Avoid dust buildup, ventilate enclosed spots, use appropriate mask and gloves.
Environmental Precautions: Sweep up gently to keep product out of drains and waterways.
Cleaning Up: Collect using a vacuum or wet methods to lower airborne dust; deposit in sealed containers for disposal; avoid dry sweeping.
Handling: Ground and bond containers, avoid creating dust clouds, use local exhaust if working with powder in large volumes.
Storage: Keep sealed in original container, park in a dry, cool, ventilated place away from open flames or ignition sources.
Special Notes: Keep away from food, drink, and animal feedstocks; do not store in direct sunlight or near oxidizers.
Occupational Exposure Limits: No specific limit for di-pentaerythritol, but stick to dust exposure guidelines (10 mg/m³ total dust, 5 mg/m³ respirable).
Engineering Controls: Local exhaust ventilation, process enclosures, maintain work environments below recommended limits.
Personal Protection: Dust mask (N95 or better), safety goggles, gloves, and protective clothing work best.
Hygiene Measures: Wash hands after work, avoid eating or smoking where dust is present, keep work clothes separate from home laundry.
Appearance: White, crystalline micronized powder
Odor: Odorless
pH: Approximately 7 (in aqueous suspension)
Melting Point: 220 - 240°C
Boiling Point: Not applicable; decomposes
Vapor Pressure: Negligible at 20°C
Solubility: Slightly soluble in water (approx 2g/L, 20°C)
Density: 1.38 - 1.41 g/cm³
Flash Point: >200°C (closed cup)
Auto-Ignition Temp: >400°C
Partition Coefficient: Not established
Decomposition Temp: >240°C
Stability: Stable under standard conditions, avoid high temperature exposure.
Incompatibility: Reactive with strong oxidizers and acids, avoid alkali metals and extreme heat.
Hazardous Reactions: Not reported under normal handling, but fine dust may form explosive mixtures with air.
Decomposition: Heating produces carbon oxides, heavier burning may trigger small traces of other organic breakdown products.
Acute Toxicity: Low toxicity through oral and dermal routes; LD50 (oral, rat) >5000 mg/kg.
Skin/Eye Irritation: Prolonged contact can cause mild mechanical irritation.
Respiratory Sensitization: High concentrations could trigger respiratory discomfort or cough in sensitive individuals.
Chronic Effects: No evidence of mutagenicity or carcinogenicity in animal studies—little likelihood for long-term health damage on proper use.
Additional Info: Not classified as harmful by ingestion or skin contact.
Persistence/Degradability: Readily biodegradable in soil and water; does not stick around.
Bioaccumulation Potential: Low—unlikely to build up in the food chain.
Aquatic Toxicity: Not expected to threaten fish or other aquatic creatures in low concentrations.
Mobility: Mobile in water, but rapid breakdown helps minimize environmental impact.
Other Issues: Avoid large accidental releases, as high concentrations of organic matter may affect oxygen demand in small water bodies.
Waste Treatment Methods: Collect residue in sealed containers for transfer to licensed incineration or landfill facilities; recycle or recover if feasible.
Small Quantities: Sweep up, place in properly labeled containers, and dispose of per local regulations.
Contaminated Packaging: Triple-rinse, mark up for waste disposal; do not reuse for food or drink storage.
Legal Requirements: Check local and national disposal laws—hazardous waste rules often vary by jurisdiction.
UN Number: Not regulated
Proper Shipping Name: Not classified as dangerous for road, sea, or air shipment
Hazard Class: None assigned
Packing Group: None
Environmental Hazards: Not hazardous for transport under normal procedures
Special Precautions: Keep containers well-sealed, avoid dropping or damaging packaging to stop spillage and dust dispersion during transport.
OSHA Status: Not flagged as hazardous material under US workplace standards.
TSCA Listing: Registered
Other International Inventories: Included in EINECS/ELINCS (Europe), DSL/NDSL (Canada), AICS (Australia), ENCS (Japan)
EU Classification: Not hazardous per CLP Regulation (EC 1272/2008).
Label Requirements: No signal word, hazard symbol, or hazard statement required.
Restrictions: Pay attention to dust-related workplace exposure controls and storage recommendations.
