Stored in a ventilated and dry warehouse.
1. Container: Store DINP in airtight containers made of compatible materials, such as glass or certain phthalate-resistant plastics.
2. Temperature: Keep storage area cool and well ventilated. Avoid exposure to extreme temperatures, as high temperatures can degrade chemicals.
3. Light Exposure: Please store it in a dark place or in an opaque container to avoid light, as light may cause it to degrade over time.
4. Separation: Keep DINP away from incompatible substances such as strong oxidants, acids and bases.
5. Label: All containers are clearly labeled with the chemical name, hazard information, and receipt date.
6. Safety Precautions: Ensure storage areas are equipped with appropriate safety equipment, such as spill control measures and handling personal protective equipment (PPE).
7. Regulatory Compliance: Follow any local regulations or guidelines regarding chemical storage to ensure safety and compliance.
Diisononyl phthalate (DINP) is considered to have low toxicity, but there are concerns about its potential health effects. It is classified as a plasticizer with possible endocrine disrupting properties. Some studies have shown that exposure to high levels of phthalates, including DINP, may be associated with reproductive and developmental problems, especially in vulnerable groups such as pregnant women and children.
Regulatory agencies such as the European Chemicals Agency (ECHA) and the U.S. Environmental Protection Agency (EPA) have evaluated DINP and established guidelines for its safe use. While DINP is generally considered safe in many applications, it is important to follow safety guidelines and regulations to minimize exposure.


When transporting Diisononyl Phthalate (DINP), specific precautions must be followed to ensure safety and regulatory compliance. Here are some key considerations to take into account:
1. Regulatory Compliance: Make sure you comply with local, national, and international regulations regarding the transportation of dangerous goods. This may include following guidelines set by organizations such as the U.S. Department of Transportation (DOT) or the International Air Transport Association (IATA).
2. Proper Labeling: All packages containing DINP should be labeled with the appropriate hazard symbol and handling instructions. Use the correct shipping name and UN number, if applicable.
3. Packaging: Use suitable containers that are DINP compatible. Make sure the packaging is sturdy and leak-proof to prevent spillage during transportation.
4. Documentation: Prepare and include all necessary shipping documentation such as Safety Data Sheets (SDS), shipping manifests, and any required permits.
5. Temperature Control: If necessary, ensure the method of transport maintains appropriate temperature conditions to prevent product deterioration.
6. Training: Ensure that personnel involved in the transportation process are trained to handle hazardous materials and understand emergency procedures in the event of a spill or accident.
7. Emergency Response: Develop an emergency response plan in the event of a leak or spill during transport. This should include contact information for local emergency services and containment and cleanup procedures.
8. Avoid incompatible substances: Ensure that DINP is not transported together with incompatible substances that may cause risks during transportation.
