Methods for Cleanup: Absorb with inert material like sand or earth, sweep up carefully, dispose in accordance with local regulations
Environmental Precautions: Avoid release to drains, surface waters, soils
Handling: Handle in well-ventilated areas, wear recommended PPE, prevent spills and splashes, wash thoroughly before breaks and after work
Safe Storage: Store in tight container, cool dry place, away from strong oxidizers and direct sunlight
Requirements for Storage Areas: Secure upright containers, segregated from food products, properly labeled
Special Sensitivity: Keep away from sources of ignition, static discharge preventive measures recommended for transfers
Occupational Exposure Limits: Not established for this mixture, refer to individual ingredient limits where available
Engineering Controls: Adequate general and local exhaust ventilation
Personal Protection: Chemical-resistant gloves (e.g. nitrile), safety goggles, lab coat or apron
Respiratory Protection: Respirator for high vapor concentration or confined areas
Hygiene Measures: No eating, drinking, or smoking in handling area, wash hands and face thoroughly after use
Environmental Exposure Controls: Prevent uncontrolled release or spillage
Appearance: Transparent to pale yellow oily liquid
Odor: Spicy, cinnamon-like aroma
Odor Threshold: Distinct at low concentrations
pH: Not applicable (non-aqueous)
Melting/Freezing Point: Below room temperature
Boiling Point/Range: Over 180°C (propylene glycol boils at 188.2°C)
Flash Point: Above 93°C (closed cup, varies by blend ratio)
Evaporation Rate: Slower than water
Flammability: Combustible liquid, not highly flammable
Vapor Pressure: Low at 20°C
Vapor Density: Heavier than air
Solubility in Water: Completely miscible due to propylene glycol content
Partition coefficient (n-octanol/water): Log Pow for cinnamic aldehyde around 2.1
Decomposition Temperature: Decomposes above 200°C, releases formaldehyde, benzaldehyde, carbon oxides
Viscosity: High, similar to propylene glycol
Chemical Stability: Stable under normal storage, reacts with strong oxidizing agents
Incompatible Materials: Strong acids, alkalis, oxidizers, heat sources
Hazardous Decomposition: Carbon monoxide, carbon dioxide, organic vapors under fire or overheating
Polymerization: Does not occur under recommended conditions
Reactivity Hazards: Vapors can oxidize, form peroxides over time if stored improperly
Routes of Exposure: Skin contact, eye exposure, inhalation, ingestion
Acute Toxicity: Low oral toxicity for propylene glycol (LD50 rat: 20 g/kg); cinnamic aldehyde shows moderate toxicity (LD50 oral rat: ~2 g/kg)
Skin Sensitization: Cinnamic aldehyde can provoke allergic dermatitis
Respiratory Irritation: Inhalation of high vapor levels may cause throat and lung discomfort
Eye Effects: Causes redness and watering, may provoke severe irritation
Chronic Exposure: Prolonged contact may bring skin sensitization and dermatitis
Carcinogenicity: No evidence for IARC, NTP or OSHA classification as human carcinogen
Reproductive Toxicity: Animal studies do not indicate significant hazard at occupational exposures
Ecotoxicity: Cinnamic aldehyde toxic to aquatic organisms (EC50 Daphnia ~0.7 mg/L, fish moderately sensitive), propylene glycol less hazardous (LC50 fish >40,000 mg/L)
Persistence and Degradability: Propylene glycol readily biodegradable, cinnamic aldehyde quickly degrades by hydrolysis and microbial pathways
Bioaccumulation: Low potential due to log Pow and rapid breakdown
Mobility in Soil: Expected to be mobile in water-rich soils due to propylene glycol
Other Adverse Effects: Spillage can harm aquatic environments, avoid releases to waterways and soil
Waste Disposal Methods: Collect in closed containers, dispose in accordance with regional and national regulations
Incineration: Suitable if permitted at local facility, ensure no release of hazardous combustion products
Rinse Water Handling: Do not flush down drains or release untreated into the environment
