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.

Which plasticizers make your PVC squeak with joy?
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.
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.

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

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!
