Diisononyl hexahydrophthalate

Diisononyl hexahydrophthalate (CAS 166412-78-8), commercially known as DINCH, is a non-phthalate plasticizer developed as a high-purity alternative for sensitive-end-use PVC applications. It delivers flexibility and durability to polymer formulations where regulatory compliance and low migration are procurement priorities. In medical devices and food-contact materials, DINCH meets stringent extraction thresholds.

It is ideal for PVC tubing, blood bags, and packaging films. Automotive interior components, including instrument panel skins and door liners, use DINCH-plasticized PVC to meet low-fogging and low-emission specifications. These materials often must comply with standards such as VDA 278. Flexible packaging and printing substrates benefit from its compatibility with inks and coatings where odor neutrality is a critical requirement.

Toy and childcare article manufacturers specify DINCH to satisfy REACH restrictions on conventional phthalate plasticizers in consumer goods. It ensures safety and compliance for products intended for children. DINCH is supplied as a clear liquid in bulk quantities, including ISO tank, drum, and IBC formats standard for industrial plasticizer procurement. It is produced to high-purity technical grades for global supply.

The product is available with documentation supporting food-contact and medical-device compliance requirements. Established producers supply consistent specifications aligned with major OEM and converter programs.
