Dinonyl phthalate(CAS: 84-76-4)

Dinonyl phthalate (DNP) is a colorless, transparent liquid with the chemical formula C21H20O4. It is a phthalate ester commonly used as a plasticizer in various applications due to its good flexibility and low volatility.

Dinonyl phthalate is widely used as a plasticizer in the manufacturing of flexible polyvinyl chloride (PVC) products, such as hoses, cables, and coatings. It is also utilized in the production of leather products, adhesives, and sealants due to its flexibility and good chemical resistance.

Dinonyl phthalate is generally considered safe for industrial and consumer use when handled properly. However, it should be used with caution as it may cause skin irritation. Necessary safety measures include avoiding contact with skin and eyes, and using personal protective equipment. Exposure to high concentrations may be harmful, and it should be handled in a well-ventilated area.

Dinonyl phthalate should be stored in a cool, dry place away from direct sunlight and heat sources. It should be kept in a tightly sealed container to prevent evaporation and contamination. The storage temperature should not exceed 25°C, and the container should be kept tightly closed to prevent moisture absorption.
