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.
DNIP is manufactured through production processes of the following substances: 1,2-benzenedicarboxylic acid, 1,2-isononyl ester and 1,2-benzenedicarboxylic acid, di-C9-11-branched alkyl esters, C9-rich.
DNIP is often used in the following products: adhesives and sealants, coating products, lubricants and greases and polymers.
Packaging, plastic materials:
It is also used in the packaging of household products: for example machine wash liquids/detergents, automotive care products, paints and coating or adhesives, fragrances and air fresheners.
This chemical can be often found in plastic materials that consist of PCV (DNIP is a PVC plasticizer) for example toys, footwear, food packaging, gloves, purses and furniture.
In automotive, it can be found in following: hydraulic liquids in automotive suspension, lubricants in motor oil and brake fluids.
DNIP can be found in log-life building materials: metal, wooden and plastic construction and building materials, flooring.
