Application

1. Food additives, because of its fruity aroma similar to apples or pineapples, it is often used in food flavors, such as candies, baked goods and beverages, to enhance the flavor.

2. Flavor and fragrance ingredients: used in daily chemical products (such as perfumes, soaps, and skin care products) to provide a fresh fruity aroma.

3. Cleaners: used for metal surface treatment or electronic component cleaning, effectively removes grease and evaporates quickly.

4. Used as a medium-polar solvent in coatings and ink solvents.

Safety Information

  • This information is a summary based on the Globally Harmonized System of Classification and Labelling of Chemicals (GHS).
    • 1. GHS Classification
      • Flammable Liquids (Category 2)
    • 2. GHS Label Elements
      • Pictogram:
        • Flame (GHS02)
      • Signal Word: Danger
      • Hazard Statements (H-Statements):
        • H225: Highly flammable liquid and vapor.
      • Precautionary Statements (P-Statements):
      • Prevention:
        • P210: Keep away from heat, hot surfaces, sparks, open flames and other ignition sources. No smoking.
        • P233: Keep container tightly closed.
        • P240: Ground and bond container and receiving equipment.
        • P241: Use explosion-proof electrical/ventilating/lighting equipment.
        • P280: Wear protective gloves, eye protection, and face protection.
      • Response:
        • P303 + P361 + P353: IF ON SKIN (or hair): Take off immediately all contaminated clothing. Rinse skin with water or shower.
        • P370 + P378: In case of fire: Use dry sand, dry chemical or alcohol-resistant foam to extinguish.
      • Storage:
        • P403 + P235: Store in a well-ventilated place. Keep cool.
      • Disposal:
        • P501: Dispose of contents/container to an approved hazardous waste disposal plant.
    • 3. Summary of Primary Hazards
      • Fire Hazards: Highly flammable. Vapors are heavier than air and may travel a considerable distance to a source of ignition and flash back. Forms explosive mixtures with air. The liquid is volatile and gives off invisible vapor.
      • Health Hazards: Not classified for acute health hazards under GHS, but high vapor concentrations can be irritating to the eyes and respiratory system and may cause central nervous system effects such as dizziness and nausea.
      • Environmental Hazards: While not classified as hazardous to the aquatic environment, large spills should be contained and prevented from entering waterways.
