Application

1. Food additives, commonly used to prepare fruity flavors such as banana, pineapple, apple, pear, and cream, and added to foods such as whiskey, cheese, bread, and beverages.

2. Flavors and spices, used to prepare flavors such as apple, pear, banana, and cream, which can be used in daily chemicals, cosmetics, perfumes, skin care products, shampoos, plastics, soap flavors, tobacco flavors, and softeners for laundry detergents.

3. Industrial solvents: As a medium-to-high boiling point solvent (boiling point of about 166°C), and with low toxicity, it is used as a solvent for coatings, paints, inks, and adhesives, effectively dissolving resins and greases and balancing the evaporation rate.

4. Plasticizers and coating raw materials: Butyl ester derivatives (such as butyl acrylate) can be used to produce plastic plasticizers and acrylic resin coatings. As an auxiliary plasticizer, it enhances the flexibility of plastic products and is often used in combination with other plasticizers.

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 3)
    • 2. GHS Label Elements
      • Pictogram:
        • Flame (GHS02)
      • Signal Word: Warning
      • Hazard Statements (H-Statements):
        • H226: 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.
        • 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: Flammable liquid and vapor. Vapors are heavier than air and can form explosive mixtures with air. Vapors may travel to a source of ignition and flash back.
      • Health Hazards: Not classified for acute health hazards, but prolonged or repeated contact may cause skin and eye irritation. High vapor concentrations may cause drowsiness or dizziness.
      • Environmental Hazards: While not classified as hazardous to the aquatic environment under GHS, large spills should be contained and prevented from entering waterways.
