Chemical Name: Anisaldehyde propyleneglycol acetal
Purity: Typically ≥ 95%
Impurities: Structural isomers, minor propylene glycol by-products, trace residuals of anisaldehyde and 1,2-propylene glycol
Additives: None typically added intentionally for standard commercial grades
Inhalation: Move person to fresh air, support breathing, consult medical attention for any discomfort, maintain clear airway.
Eye Contact: Flush eyes thoroughly with running water for at least 15 minutes; do not rub eyes; seek immediate medical care if discomfort persists.
Skin Contact: Remove contaminated clothing, rinse skin thoroughly with water and mild soap; persistent irritation warrants medical attention.
Ingestion: Rinse mouth, do not induce vomiting, seek medical attention immediately, provide information about exposure amount and time.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, alcohol-resistant foam, or water spray; do not use direct water jet on large fires.
Hazards from Combustion: Releases carbon monoxide, carbon dioxide, possible traces of acrid smoke and other combustible organic decomposition products.
Protective Equipment & Precautions: Firefighters use self-contained breathing apparatus, wear full protective gear including gloves, chemical splash goggles; remove containers from area if feasible.
Flammability: Flammable liquid; vapors may travel and ignite far from initial source of release.
Personal Protection: Evacuate area, ventilate if safe, prevent skin and eye exposure with chemical-resistant gloves and face protection, respirators for significant vapor concentrations.
Methods for Clean Up: Contain spill with inert absorbent (sand, earth, or vermiculite), scoop up and place in secure, labeled waste container; wash area with water and detergent – prevent product from entering drains or waterways.
Environmental Precautions: Avoid uncontained flow into soil, water bodies, or sewage systems, report large releases to relevant authorities.
Handling: Use only in well-ventilated workspaces; keep away from heat, sources of ignition; avoid prolonged contact or repeated exposure; do not eat, drink, or smoke while handling.
Storage: Store in tightly closed, labeled containers made of compatible materials; locate in a cool, dry, well-ventilated area; segregate from oxidizers and acids, maintain temperature stability away from direct sunlight.
Special Precautions: Ground and bond containers during transfer to prevent static discharge; store away from incompatible materials such as strong oxidizing agents.
Occupational Exposure Limits: No specific occupational exposure limit for this compound established; control exposure through engineering measures.
Engineering Controls: Local exhaust ventilation, fume hoods, regular air monitoring practices.
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles or face shields, lab coats or chemical aprons, closed footwear, suitable respiratory protection when airborne levels are elevated.
Industrial Hygiene: Wash hands after use, handle in accordance with good industrial hygiene and safety practice.

Vapor Pressure: Low at room temperature
Solubility: Slightly soluble in water; soluble in organic solvents
Density: Approximately 1.07 g/cm³
Partition Coefficient (n-octanol/water): Not available
Autoignition Temperature: Not established
Decomposition Temperature: Not determined
Chemical Stability: Stable under recommended storage conditions and normal handling.
Conditions to Avoid: Open flames, heat sources, spark-producing equipment, ultraviolet light exposure.
Incompatible Materials: Strong oxidizers, reducing agents, acids, some metals.
Hazardous Decomposition: Forms potentially hazardous products including carbon monoxide, carbon dioxide, unidentified organic compounds.
Polymerization: Has not been reported to polymerize under normal use conditions.
Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion.
Acute Effects: May cause moderate skin and eye irritation, respiratory discomfort if exposed to high vapor concentrations.
Chronic Effects: Repeat exposure may increase skin sensitivity, some anecdotal reports of mild allergic reaction in sensitive individuals.
Data References: Acute oral toxicity (LD50) reported at moderate to high dose (animal data), no specific carcinogenicity or mutagenicity reported in available literature.
Other Information: Not considered sensitzing by skin patch tests in most studies, lacks official harmonized GHS classification for reproductive toxicity.
Acute Ecotoxicity: Moderately hazardous to aquatic organisms, with potential for long-term effects in water environments.
Persistence and Degradability: Expected to biodegrade slowly in natural conditions; bioaccumulation potential considered low.
Mobility in Soil: Only slight mobility due to low water solubility.
Other Adverse Effects: Use containment to prevent contamination to streams or soil; accidental releases can impact small aquatic organisms in confined water bodies.
Disposal Methods: Collect chemical waste into sound, properly labeled containers for delivery to licensed hazardous waste disposal facilities; do not discharge into surface drains or water courses.
Container Disposal: Completely empty containers before recycling or discarding; decontaminate with water or appropriate solvent if feasible according to local environmental regulations.
Special Precautions: Avoid disposal practices that might lead to environmental contamination or worker exposure; coordinate with appropriate local authorities.
