DINCH (Diisononyl Cyclohexanoate) | Vinyl Plasticizer

DINCH is a foundational plasticizer, it may not deliver the ultra-buttery softness of some alternatives, but it more than makes up for it with exceptional stability, migration resistance, and longevity. Think of it as a more robust, endurance-focused cousin to DOTP.

DINCH offers a slightly firmer feel and slower absorption rate, yet provides outstanding resistance to UV exposure and plasticizer migration. It was originally designed as a drop-in replacement for traditional phthalate plasticizers and has since become one of the most trusted options in modern PVC manufacturing.

In fact, DINCH + DOTP likely form the core plasticizer package used in many, if not most, inflatable pool toys today, meaning the toy you’re treating probably already contains DINCH in its formulation.

Best For: General vinyl conditioning; medium-low softness with maximum stability
Paint Safety: Excellent
Absorption Speed: Slow
Resulting Feel: Firm, sturdy, strong
