Chemical Identity: 2-Methyl-2-Propyl-1,3-Propanediol
Content: ≥ 98% by weight
Impurities: Minor levels of related glycol derivatives (< 2%) found in batches; none classified as hazardous under GHS.
Other Ingredients: No stabilizers, solvents or additives present in standard production material.
Inhalation: Move exposed person to fresh air, keep comfortable for breathing; provide medical attention if symptoms persist such as coughing or wheezing.
Skin Contact: Remove contaminated clothing, thoroughly wash exposed area with soap and water; persistent irritation calls for consultation with medical personnel.
Eye Contact: Rinse cautiously with water for several minutes, hold eyelids open; if discomfort or redness does not subside, seek medical evaluation.
Ingestion: Rinse mouth with water, provide small amounts to drink unless unconscious or convulsing; do not induce vomiting without medical advice; consult professional care.
Advice for Immediate Medical Attention: Symptoms linked with large exposure or sensitive individuals should receive physician assessment, especially for ongoing respiratory or gastrointestinal symptoms.
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, or foam may be used in accordance with fire scenario.
Special Hazards: Combustion can yield carbon monoxide and carbon dioxide; avoid inhaling smoke or combustion products.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and personal protective clothing to guard against potential toxic decomposition.
Procedures: Evacuate area, stay upwind, keep containers cool with water if safe to do so, employ containment to prevent firewater runoff entering drains or waterways.
Flammability: Low risk under normal storage, but heating can increase flammability; avoid storage near open flames or high-heat sources.
Personal Precautions: Limit access, use personal protective equipment, prevent dust or mist formation by damping spilled material.
Environmental Precautions: Block entry to sewers, surface, or groundwater; deploy absorbent materials to contain spillage.
Cleaning Up: Gather material with non-sparking tools, collect residues in appropriate containers for disposal, ventilate area well.
Decontamination: Flush surface with water after material removal; avoid uncontained washing into the environment.
Safe Handling: Use adequate ventilation, handle with chemical-resistant gloves, avoid breathing dust or vapors; keep product closed and labeled.
Storage Conditions: Store in original tightly closed containers, sheltered from sunlight and moisture, maintain mild environmental temperature range.
Incompatibilities: Strong oxidizers may react violently; isolate from acids, bases, and other reactive chemicals.
Transfer Precautions: Ground and bond containers during transfer to avoid static discharge; avoid using glass containers if possible for large quantities.
Exposure Limits: No occupational exposure limits established for this chemical.
Engineering Controls: Implement local exhaust or general ventilation; for powder processing, use dust extraction.
Personal Protection: Wear chemical splash goggles and gloves made from nitrile or neoprene; in operations generating dust or vapor, use a suitable particulate respirator.
Hygiene Measures: Wash hands and face after handling, do not eat, drink or smoke in processing areas, frequent laundering of work clothing encouraged.
Environmental Controls: Install spill containment systems around storage zones, monitor workplace air for glycol vapors if heated.
State: Solid
Color: White to off-white
Odor: Mild, nearly odorless
Melting Point: Around 62-64 °C
Boiling Point: Above 220 °C
Density: Approximately 0.965 g/cm³ at 20 °C
Water Solubility: Soluble
Vapor Pressure: Negligible at ambient temperature
Partition Coefficient (log Kow): Low, favors water solubility

Chemical Stability: Stable at standard ambient temperature and pressure
Reactivity: Not reactive toward most materials encountered in normal industrial settings
Hazardous Reactions: No known dangerous polymerization or hazardous reaction under usual conditions
Conditions to Avoid: Strong heat sources, contact with oxidizers or strong reducing agents
Decomposition Products: Carbon oxides upon combustion, trace organic vapors possible at elevated temperatures
Routes of Entry: Inhalation, ingestion, skin and eye contact
Acute Effects: Mild irritation in sensitive individuals; not expected to cause severe toxicity in small accidental exposures
Chronic Effects: Limited data on repeated exposure, though structurally related compounds show low systemic toxicity in animal studies
Corrosivity/Sensitization: Not corrosive; not a skin sensitizer based on available data
Carcinogenicity: No evidence of carcinogenicity in animal or epidemiological studies
Mutagenicity/Reproductive Toxicity: Not mutagenic or reproductive toxic based on analog data
LD50/LC50: Estimated oral LD50 (rat) above 2000 mg/kg, indicating low acute toxicity
Aquatic Toxicity: No acute toxicity to aquatic organisms at concentration typical in accidental releases
Persistence/Degradability: Expected to biodegrade over time due to molecular structure
Bioaccumulation: Product unlikely to bioaccumulate due to low octanol-water partitioning
Soil Mobility: Moderately mobile if released, dissipates with adequate soil moisture and microbial activity
Other Effects: No known chronic effects on sediment or soil microorganisms from occasional low-level discharges
Waste Treatment: Dispose in accordance with regional, national, and local regulations; authorized chemical waste facilities recommended
Container Disposal: Rinse small empty containers, recycle or dispose safely; larger drums returned to supplier when feasible
Special Instructions: Avoid unregulated dumping; incineration of waste requires control for glycol incineration byproducts
Avoidance Measures: Eliminate releases to waterways, favor containment, neutralize spills with inert absorbents
