Synonyms: Not limited to but includes dexpanthenol
Relevant chemical group: Alcohols

Hazard Identification

Main hazards: Not considered hazardous under normal conditions
Potential effects: Mild eye or skin irritation can occur with contact
Inhalation risk: Inhalation of dust or mist can cause mild respiratory irritation
Chronic exposure: Regular use rarely leads to long-term issues
Label elements: No major pictogram requirement
Signal word: Not generally required due to low hazard classification
Other concerns: Slippery surfaces if spilled

Composition / Information on Ingredients

Main ingredient: D-Panthenol, purity typically above 98%
Impurities: Generally below threshold for relevant safety concerns
Structure: Simple organic alcohol structure, derived from pantothenic acid
Ingredient list: No significant additives or contaminants
Allergen status: Free from common allergenic compounds

First Aid Measures

Eye contact: Flush eyes gently with water for several minutes, remove contacts if present
Skin contact: Wash with soap and water, rinse thoroughly
Inhalation: Move to fresh air; mild symptoms resolve on their own
Ingestion: Rinse mouth, drink water; quantities involved in lab or household settings rarely reach harmful levels
Advice to physician: Symptomatic treatment based on individual reaction
Special cases: Seek medical help if irritation persists or significant discomfort continues

Fire-Fighting Measures

Suitable extinguishing media: Water spray, dry chemical, foam, or carbon dioxide
Fire hazards: Low flammability; can burn if deeply heated
Combustion byproducts: May generate carbon dioxide and carbon monoxide
Instructions for firefighters: Wear standard protective gear, avoid inhaling smoke
Explosion risk: Not explosive in solid or liquid state
Protective actions: No unusual fire-fighting procedures needed beyond routine caution

Accidental Release Measures

Personal precautions: Prevent eye and skin contact
Spill response: Clean spills promptly; use water or mild detergent, mop up small quantities
Environmental precautions: Do not wash large amounts into surface water
Containment: Handle with routine lab hygiene; minimize dust or mist
Clean-up methods: Collect material and dispose of according to local rules
Ventilation: Use in a well-ventilated area, especially with fine powder

Handling and Storage

Handling: Use non-porous gloves, avoid splashing or generating dust
Storage conditions: Store in sealed container in cool, dry, well-ventilated space
Temperature tolerance: Stable at typical room temperatures, keep away from excessive heat
Compatibility: Store away from strong acids, oxidizing agents
Packaging: Reseal containers tightly after each use to avoid contamination
Hygiene practices: Wash hands after handling, avoid eating or drinking around open containers

Exposure Controls and Personal Protection

Engineering controls: Local exhaust ventilation or typical fume hoods sufficient for most uses
Personal protective equipment: Safety goggles, lab coat, non-porous gloves
Respiratory protection: Mask recommended if dust becomes airborne, especially with powders
Hand protection: Glove use recommended for prolonged exposure
Exposure limits: Not assigned specific regulatory limits in incidentally encountered situations
Skin protection: Long sleeves and lab coat reduce risk of irritation

Physical and Chemical Properties

Physical state: Usually clear, colorless to slightly yellow liquid or crystalline powder
Odor: Mild, typical of organics
Solubility: Easily dissolves in water and alcohol
pH (aqueous solution): Neutral to slightly acidic
Melting point: Near 64-68°C for powder
Boiling point: Decomposes before boiling under atmospheric pressure
Density: About 1.2 g/cm³
Viscosity: Noticeably viscous in solution
Other notable properties: Hygroscopic in nature, absorbs moisture from air

Stability and Reactivity

Chemical stability: Remains stable under standard use and storage
Conditions to avoid: High humidity, excessive heat, strong oxidizers
Reactivity: Not highly reactive, does not undergo hazardous polymerization
Hazardous decomposition products: Carbon oxides in event of complete combustion
Incompatible materials: Strong acids, alkalis, and oxidizing chemicals
Shelf life: Can be long if kept dry and cool, with sealed packaging

Toxicological Information

Acute toxicity: Low oral, skin, and inhalation toxicity
Sensitization: Rare allergic reactions reported; otherwise generally well-tolerated
Irritation: Mild, reversible irritation possible for eyes and skin
Chronic effects: No evidence for carcinogenicity or mutagenicity based on current research
Symptoms of exposure: Itchiness, slight redness, or watering eyes
Populations at risk: Individuals with pre-existing sensitivities may experience more pronounced symptoms

Ecological Information

Environmental fate: Breaks down easily in the natural environment
Aquatic toxicity: Little to no toxicity to fish or aquatic organisms under usual concentrations
Persistence and degradability: Readily biodegradable
Bioaccumulation potential: Low
Soil mobility: High water solubility facilitates dispersion; unlikely to persist
Special concerns: Discharging bulk amounts to surface water is best avoided to maintain good stewardship

Disposal Considerations

Disposal methods: Small quantities can be mixed with general household or laboratory waste if local laws permit
Large-scale disposal: Use licensed waste disposal contractor and consult local guidelines
Containers: Rinse empty containers before recycling or disposal
Regulatory status for waste: Usually not classified as hazardous waste: verify with regional authorities
Reuse: Only recover for re-use if stored properly and uncontaminated
Good practice: Avoid flushing down drains if achievable

Transport Information

UN number: Not classified as a dangerous good under global transport rules
Shipping name: D-Panthenol
Packing group: Not assigned due to low hazard status
Class: Not regulated for road, rail, air, or sea transport
Transport precautions: Protect against moisture, keep container sealed
