Phthalates are a family of colorless, odorless, durable plasticizers that increase the flexibility and pliability of polymer materials. They are used in a variety of products, including automotive components, synthetic leather, electric cables, and hoses for household appliances and wiring.
Diisononyl phthalate (DINP) is a high molecular weight PVC plasticizer that provides a good balance of cost savings and properties. It has lower volatility, improved cold temperature flexibility, and better permanence in the final product.
Physical Properties
Phthalates are a class of organic chemical compounds used to soften polyvinyl chloride (PVC). Diisononyl phthalate is an important substitute for di-2-ethylhexyl phthalate (DEHP), which is being phased out due to health concerns.
This plasticizer is highly compatible with PVC and shows good permanence in the final product, and it also has lower volatility than DEHP. It is a good choice for a wide variety of flexible PVC applications, including flooring, wire and cable insulation, gloves, tubing, artificial leather, footwear, roofing materials, and toys.
It is also found in many personal-care products, including perfume, eye shadow, moisturizer, nail polish, liquid soap, and hair spray. In addition, it is also used in modern electronics and medical devices such as catheters and blood transfusion devices.
Chemical Properties
Diisononyl phthalate is a high molecular weight, general use plasticizer for flexible PVC. It offers low volatility, good cold temperature flexibility and permanence in the final product.
It can be used to manufacture a variety of PVC products such as plastisols, extruded parts and molded parts. It also finds use in the automotive, construction, adhesive, home, footwear and wire & cable industries.
Unlike other plasticizers, it is very resistant to changing temperatures and shows good thermal insulation as well as long lasting wear and durability. It can be mixed with other phthalates to meet specific product requirements.
Phthalates are a group of chemicals that can interfere with the endocrine system, disrupting hormone production and interfering with sexual development in infants and adults. They can also cause abnormalities in adipose tissue and metabolic homeostasis. These changes may lead to obesity in children, which is a serious health concern. These chemicals have been linked to a number of health effects, including cancer and birth defects in the reproductive organs.
Biological Properties
Diisononyl phthalate (DINP) is a high-molecular-weight phthalate that is widely used as a plasticizer. It is a component in a number of different types of plastic products, including PVC plastics and vinyls.
Its physical properties enable it to be incorporated into a variety of materials, making it an important additive for many applications in the consumer and industrial sectors. However, it also has the potential to pose a health risk.
This is because phthalates are endocrine disruptors, which can influence the function of the endocrine system. This can include altering the function of hormone receptors and affecting adipose tissue, which may increase the risk of obesity.
In addition, a number of studies have shown that exposure to phthalates can cause hepatocarcinogenicity and other adverse effects on the liver. These effects are attributed to the ability of phthalates to mimic the action of certain hepatocellular enzymes, which can lead to apoptotic activation in the liver. The mechanism is not completely understood, but it is thought to involve the breakdown of hepatocellular lipids.
Health Effects
Diisononyl phthalate (DINP) is a plasticizer used in a variety of products. It is found in toys, flooring, gloves, drinking straws, garden hoses, and sealants for food packaging.
Phthalates are toxic chemicals that affect human reproductive health. They may disrupt hormone-related activities in the fetus or infant and lead to abnormalities in development, such as delayed or malformed growth or delayed puberty.
Several studies have shown that exposure to high doses of phthalates, such as those in infant products, can cause birth defects and other developmental problems in rodents. They can also irritate the skin, and have been linked to cancer in laboratory animals.
