Diisononyl phthalate (DINP) is a phthalate used as a plasticizer. DINP is typically a mixture of chemical compounds consisting of various isononyl esters of phthalic acid, and is commonly used in a large variety of plastic items.
Characteristics of Diisononyl Phthalate
Diisononyl phthalate is a kind of phthalate, with low volatility and good processing performance. It can replace DOP as an extrusion molding agent for wires and cables, PVC floor materials and vinyl acetate dairy industry, etc.
Production of Diisononyl Phthalate
Diisononyl Phthalate is produced by esterifying phthalic anhydride with isononyl alcohol in a closed system. The isononyl alcohol used in the synthesis of Diisononyl Phthalate is produced by the dimerization of butene. Elevated temperature (140-250 °C) and catalyst can accelerate the reaction rate. Following substantially complete esterification, excess alcohol is removed under reduced pressure, and the product is then typically neutralized, washed with water, and filtered.
What is Diisononyl Phthalate used for?
Diisononyl Phthalate is a phthalate, a group of industrially important chemical substances used to make plastics softer. It is used for garden hoses, swimming pool linings, floor tiles and tarps. Its use in food packaging is limited. Congress has (temporarily) banned three phthalates, including diisononyl phthalate, whose content must not exceed 0.1% of children’s toys and child care products that can be put in children’s mouths.
Chemical properties of Diisononyl Phthalate
The plasticizing properties of Diisononyl Phthalate are similar to DEHP, and Diisononyl Phthalate is a general-purpose plasticizer
Diisononyl Phthalate has low volatility and low plasticization efficiency. Compared with DEHP, it has lower plasticization efficiency, migration, water extraction rate, slightly higher gelation temperature and electronic resistance; its low volatility, not only can extending product life can also reduce evaporation during the manufacturing process. Using Diisononyl Phthalate to replace DEHP, which has higher plasticization efficiency and specific gravity, can save considerable volume cost.
What is the harm of Diisononyl Phthalate?
Diisononyl Phthalate harms the environment
If Diisononyl Phthalate is released into the environment, it will interact with particles and water in the soil. It will not move in the soil. It will be decomposed by microorganisms in soil and water. It may accumulate in aquatic organisms. A small amount will move from moist soil and water to the air surface.
Children exposed to Diisononyl Phthalate dust in the air may develop asthma. Exposure to Diisononyl Phthalate in childhood may change the reproductive development of men and women. In experimental animals repeatedly fed with medium to high doses of Diisononyl Phthalate, liver and kidney damage, anemia (red blood cell reduction) and weight loss were found.
The European Union has set a maximum specific migration limit from food contact materials of 9 mg/kg food for the sum of diisononyl phthalates and diisodecyl phthalates.

What specimen can be detected by BALLYA Diisononyl Phthalate Test?
Specimen include: all kinds of grains, food and edible oil. Widely used in feed industry and food processing industry. You can choose the right products according to your needs.
Significance of testing Diisononyl Phthalate
To protect the animal have health grain, food, and edible oil, avoid contaminated food. The excess diisononyl phthalate is harmful for animal being, can’t take too much in the body.
1. Take some grain or food specimen 2. Add the supernatant to cassette 3. Wait for 15 minutes to result 4. The details of operation, refer to the kit instruction
Limitations of BALLYA Diisononyl Phthalate Test?
BALLYA Diisononyl Phthalate Test is a qualitative test kit. It’s only for screening purpose. If have positive cases or suspected case, maybe use other detection method to make a further detection, such as, ELISA, PCR, qPCR, etc.
BALLYA Diisononyl Phthalate Test is suitable for the detection of diisononyl phthalate residues in grain, food and edible oil. Simple operation, high accuracy and short detection time are the characteristics of this product.
It can be widely used in food and drug administration, health departments, higher education institutions, scientific research institutes, agricultural departments, animal husbandry and veterinarians, breeding farms, slaughterhouses, food and meat products deep processing enterprises, inspection and quarantine departments and other units.
