INSPITE OF BEING PHTHALATE PLASTICIZERS, WHY DINP AND DOTP
The difference is clearly evident from their chemical structure. While DOP and DINP are ortho phthalates, DOTP is para phthalate. In structures of DOP and DINP, one can see that the...

Diisononyl Phthalate (DINP) - Proposition 65 Warnings Website
DINP can be gradually released from consumer products into indoor environments such as homes, schools, daycare centers, offices and cars. It settles on floors and other surfaces, and can accumulate in dust and air. Exposure can result from contact with products containing DINP.
What Is The Difference Between DOTP And DINP？ - News
Compared with DOP, DINP has a larger molecular weight and longer carbon chain, so it has better aging performance, anti-migration performance, anti-extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP is slightly worse than that of D0P.
Inspite of being phthalate plasticizers, why dinp and dotp
When we compare DOP and DINP structures, in contrast to DOP, the ester portion in DINP is branched and occupies much more spacethan n-octanol in DOP. As a result of this, the migration of DINP from the PVC product is reduced or prevented and the accumulation of DINP in the environment is not possible.
- What is the difference between DOTP and DINP?
- What Is The Difference Between DOTP And DINP?
- DINP (diisononyl phthalate) is a commonly used plasticizer derived from the esterification of phthalic anhydride and isononyl alcohol. Diisononyl phthalate is abbreviated as DINP. This product is a transparent oily liquid with a slight odor.
- Is DINP better than d0p?
- Compared with DOP, DINP has a larger molecular weight and longer carbon chain, so it has better aging performance, anti-migration performance, anti-extraction performance and higher high temperature resistance. Correspondingly, under the same conditions, the plasticizing effect of DINP is slightly worse than that of D0P.
- What is the difference between DOP and DOTP?
- It provides excellent flexibility and elongation properties to PVC products. DOTP offers similar plasticizing performance to DOP but with some advantages, including higher thermal stability, improved resistance to migration, and better compatibility with PVC resins. DOTP also exhibits better UV resistance and weatherability compared to DOP.
- What is the difference between DOP and DINP structures?
- In structures of DOP and DINP, one can see that the ester radicals are positioned side by side in ortho position, on the benzene ring. When we compare DOP and DINP structures, in contrast to DOP, the ester portion in DINP is branched and occupies much more space than n-octanol in DOP.
- Which plasticizer is better DOP or DOTP?
- Overall, while DOP and DOTP both serve as effective plasticizers for PVC, DOTP is often preferred over DOP due to its safer profile, better environmental performance, and regulatory compliance. However, the choice between DOP and DOTP may depend on specific application requirements, cost considerations, and regulatory compliance needs.
- Which plasticizer can replace DOP?
- DINP and DOTP are perfect plasticizers for replacing DOP: DINP (Di-Iso-Nonyl Phthalate) and DOTP (Di octyl terephthalate), have the same softening effect as DOP (efficiency factor 1.03). At the same time, both products have been classified as unobjectionable.
