Signal Word: Warning
Pictograms: Exclamation mark (for irritation)
Precautionary Statements: Avoid contact with eyes and prolonged skin exposure, keep away from open flame or hot surfaces, use only with adequate ventilation
Potential Health Effects: May cause redness, dryness, or cracking of skin; eye contact can lead to temporary discomfort; low toxicity if swallowed but may cause gastrointestinal upset

Composition / Information on Ingredients

C12 Fatty Alcohol (Lauryl Alcohol): CAS No. 112-53-8, 40–60%
C14 Fatty Alcohol (Myristyl Alcohol): CAS No. 112-72-1, 40–60%
Impurities or Additives: Less than 2% unspecified long-chain alcohols or esters (naturally occurring or process-related)

First Aid Measures

Inhalation: Move to fresh air immediately, keep at rest, seek medical advice if symptoms persist, provide oxygen if breathing becomes difficult
Skin Contact: Remove any contaminated clothing, wash skin thoroughly with soap and plenty of water, watch for signs of irritation, get medical attention if discomfort develops or persists
Eye Contact: Rinse eyes gently with water for at least 15 minutes; do not rub; lift upper and lower eyelids occasionally; seek prompt medical help if irritation continues
Ingestion: Rinse mouth with water, do not induce vomiting, get medical assistance if large amounts have been swallowed or symptoms arise

Fire-Fighting Measures

Suitable Extinguishing Media: Use dry chemical foam, carbon dioxide, or water spray
Fire Hazards: Combustible at high temperatures, decomposes when heated to produce irritating or toxic fumes (including carbon monoxide and carbon dioxide)
Special Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Specific Hazards Arising from Chemical: Vapors may form explosive mixtures with air in case of fire
Specific Firefighting Procedures: Isolate area, do not allow runoff from fire control to enter sewers or waterways, cool exposed containers with water spray

Accidental Release Measures

Personal Precautions: Avoid breathing vapors, avoid contact with skin and eyes, provide adequate ventilation in affected area, use personal protective equipment (PPE) as recommended
Spill Response: Stop leak if possible without risk, contain spill with non-combustible absorbent material such as sand or earth, shovel into containers for disposal
Environmental Precautions: Prevent product from entering drains, waterways, or soil to avoid negative impact on aquatic organisms
Clean-up Methods: Collect and dispose of according to local regulations, ventilate affected area, wash spill area after pick-up is complete

Handling and Storage

Safe Handling: Work in a well-ventilated area, minimize exposure, avoid splashing or generating mist, practice good personal hygiene by washing hands after handling
Storage Conditions: Store in tightly closed containers, keep in a cool, dry, and well-ventilated space, keep away from sources of ignition or heat,
Incompatible Materials: Strong oxidizing agents, acids, and bases, to prevent risk of hazardous reactions
Other Precautions: Keep away from food and drinking water, keep containers properly labeled, follow local safety protocols

Exposure Controls and Personal Protection

Engineering Controls: Use local exhaust or general ventilation to maintain airborne concentrations below recommended exposure limits
Personal Protective Equipment: Wear chemical-resistant gloves (nitrile or neoprene), safety goggles or face shield for eye protection, protective clothing to prevent skin contact
Respiratory Protection: Use approved respirators for vapor or mist if exposure limits might be exceeded or if ventilation is inadequate
Hygiene Measures: Wash hands and face thoroughly after handling, do not eat, drink, or smoke at workstations, remove contaminated clothing and wash before reuse
Exposure Limits: No specific occupational exposure limits set for lauryl-myristyl alcohol, refer to general dust or nuisance particulates guidelines if handled in powdered form

Physical and Chemical Properties

Physical State: Waxy solid or white to pale yellow flakes at room temperature, melts to clear liquid between 24°C–38°C
Odor: Mild, fatty alcohol scent
pH: Not applicable as a solid, slight alkaline nature in solution
Boiling Point: 260–300°C
Melting Point: 24°C–38°C (depends on C12/C14 ratio)
Flash Point: >140°C (closed cup)
Solubility: Insoluble in water, readily soluble in alcohol, ether, oils
Specific Gravity: 0.82–0.84
Vapor Pressure: <0.01 mmHg at 25°C
Viscosity: Thickens on cooling; liquid form flows freely when heated
Partition Coefficient (n-octanol/water): High, indicating strong hydrophobic tendency
Evaporation Rate: Negligible at ambient conditions

Stability and Reactivity

Chemical Stability: Stable at normal temperatures and pressures, resists degradation during typical storage and use
Reactivity: May react with strong oxidizers, acids, or alkalis, but unreactive in most normal conditions
Conditions to Avoid: Excessive heat, open flames, sparks, and humidity – all can accelerate decomposition
Hazardous Decomposition Products: Burning generates carbon monoxide, carbon dioxide, low levels of aliphatic aldehydes and acids
Polymerization: Will not occur spontaneously under standard temperatures and pressures

Toxicological Information

Acute Toxicity: Low oral toxicity, typical LD50 (rat, oral) >2,000 mg/kg; regarded as relatively safe for short-term contact
Skin Irritation: Causes mild to moderate irritation, especially on prolonged or repeated exposure
Eye Irritation: Can provoke transient burning, redness, and watering
Sensitization: No evidence or reports of significant allergic reaction risk in healthy individuals
Chronic Toxicity: Repeated or prolonged contact could lead to dry or cracking skin, no solid data on serious long-term effects
Carcinogenicity: No classification as carcinogen from OSHA, IARC, NTP, or EU
Mutagenicity and Reproductive Toxicity: No evidence of mutagenic or teratogenic effects in standard tests for fatty alcohols

Ecological Information

Aquatic Toxicity: May be harmful to aquatic life in high concentrations due to surfactant properties, but breaks down relatively quickly in the environment
Biodegradability: Readily biodegradable under aerobic conditions
Bioaccumulation: Low risk of bioaccumulation due to rapid degradation
Environmental Fate: Spills enter water can form slick, reduce oxygen transfer, impact fish and invertebrates temporarily
Persistence: Expected to persist in water only for a short time, quickly degrades into natural fatty acids and alcohols

Disposal Considerations

Waste Treatment Methods: Dispose in compliance with local, national, and international regulations; can be incinerated in safe, approved facilities
Disposal of Containers: Empty containers thoroughly, do not reuse unless properly cleaned, dispose of according to environmental authority guidelines
