What about "non-phthalates"?  

ExxonMobil patented DOTP (DEHT) as early as 1953. Because of its poor compatibility with PVC, the company decided not to commercialize it and shifted its focus to other, more reliable solutions. This resulted in the development of Jayflex™ DIDP and DINP plasticizers.

Squeak or leak?  

Which plasticizers make your PVC squeak with joy?

Toy ducks are fun: they float on water and squeak.
But beware of ducks containing plasticizers with poor PVC compatibility: they don’t squeak, they leak!
Which plasticizers produce squeakers and which produce leakers?

1 ExxonMobil commercializes DINP and DIDP under the brand Jayflex™
2 DINCH is a trademark of BASF
3 The American Society for Testing and Materials loop test (ASTM D3291-74) observes plasticizer compatibility with PVC during compression and while under tensile stress.

“Non-phthalate” doesn’t mean “eco-friendly”  

A few data points

  • If focusing on the manufacturing process, DOTP (DEHT) simply takes more time to produce than DINP1.The esterification of the alcohol used runs 2 to 3 times slower2
  • From cradle (crude oil extraction) to gate (product at plant), DINCH3 takes more energy to produce as it requires an additional manufacturing step vs. DINP with associated hydrogen sourcing and consumption. 
  • An ISO 14-040-44 compliant study provides a detailed picture about the potential environmental impacts of DINP from cradle to gate. Results of the study are presented in the eco-profile and environmental product declaration report, which is regarded as up-to-date high quality environmental data of European DINP production. This data is often used as a building block for Life Cycle Assessment (LCA) studies involving end use applications. 


These facts represent pieces of the overall puzzle…

3 DINCH is a trademark of BASF



Product life cycle

To fully understand the environmental impact of a particular product, the entire life cycle needs to be considered: without data to support the claim, saying DOTP (DEHT) is “eco-friendly” is not accurate.

You can’t teach an old dog new tricks  

DOTP (DEHT) was developed in 1949 and patented in 1953 by ExxonMobil but never commercialized for a good reason.

Because of its poor compatibility with PVC, the company decided NOT to commercialize DOTP (DEHT) and shift its focus to other, more reliable solutions. This resulted in the development of Jayflex™ DIDP and DINP plasticizers.


Same old dog, no new tricks.

    Fundamentals of plasticizers

    Plasticizers bring flexibility to PVC applications. They also attract misconceptions across the value chain. There are indeed similarities, but the truth is that plasticizers can also be fundamentally different!
