The Chemical Company VESTINOL® 9 Diisononyl Phthalate, C6H4(COOC9H19)2

Diisononyl Phthalate (DINP) C6H4(COOC9H19)2, is a clear, colorless, and almost odorless liquid chemical. It is soluble in most organic solvents. DINP is primarily used as a PVC plasticizer. As compared to DOP, the low volatility and better endurability of DINP significantly reduces the fume emissions during the processing procedure and improves its permanence in the final product. DINP is a mixture of isomers that have alkyl chains from 7 to 9 carbons long, but the largest portion of the mixture have chains composed of 8-carbon in length (a.k.a. isononyl alcohol). DINP is a general purpose plasticizer with a broad range of applications used in flexible PVC. It is widely used in the toy, construction, and general consumer product markets. It has limited use in food packaging and is not used in medical applications.Information provided by The Chemical Company
