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.

Where is Diisononyl hexahydrophthalate used?

• Medical devices and food-contact materials: meets stringent extraction thresholds
• PVC tubing, blood bags and packaging films
• Automotive interiors: instrument panel skins and door liners with low-fogging and low-emission specifications
• Flexible packaging and printing substrates: compatibility with inks and coatings where odour neutrality is critical
• Toy and childcare articles: satisfies REACH restrictions on conventional phthalate plasticizers
• It delivers flexibility and durability to polymer formulations where regulatory compliance and low migration are procurement priorities.

Good to know: These materials often must comply with standards such as VDA 278.

Commercial specifications

• Clear liquid in bulk quantities: ISO tank, drum and IBC formats
• High-purity technical grades for global supply
• Documentation supporting food-contact and medical-device compliance requirements
