One example of this trend is the substitution of phthalate-based DEHP by its non-orthophthalate counterpart DOTP (based on the same OXO alcohol), steadily expanding its share of the European PVC plasticiser market.
substitution factor (SF) for DINP vs. DOP is 1.06. DINP is 6% less efficient than the plasticizing efficiency of DOP). Tarkett was the first company to manufacture LVT in the U.S. in 2011 and

This colorless viscous liquid is known to be a great substitute for harmful phthalates in plastic production. One of the methods of manufacturing DOTP is by direct esterification of purified
Following the above equation, the yields of the DOTP product can be readily calculated out by using the integrations of the peaks for BDC (8.04 ppm) and DOTP (8.07
- How much ASE & DOTP are in simulants for aqueous and low alcohol foods?
- Migration of ASE, COMGHA, DINCH, DOTP, DEHCH, and TOTM in simulants for aqueous and low alcohol foods ranged from <0.02 to 0.165 mg/kg. Human biomonitoring data are available for DINCH, DOTP, DEHA, DINA, and TOTM, and indicate that total exposures from all sources are below regulatory thresholds.
- What is DOTP & how does it work?
- DOTP is mainly manufactured by direct esterification. Many process parameters need to be monitored simultaneously to guarantee high product quality and high reaction throughput—something that is not possible with traditional laboratory analysis.
- Can plasticizers be used as substitutes for ortho-phthalates?
- Over the past 10 years methods have been developed for key alternative plasticizers, which is needed and important since some of the plasticizers may be used as substitutes for ortho-phthalates, particularly in sensitive applications.
- How is high-purity DOTP obtained?
- High-purity DOTP is obtained through this process. Many parameters need to be monitored in order to guarantee a high reaction yield and high DOTP quality. Traditionally, the amount of reactants and products are measured in the laboratory after taking a sample from the production process.
- What are the characteristics of DOTP produced by esterification?
- One of the distinctive features of DOTP produced by esterification is the qualitative stability of subsequent batches of the product in terms of transparency (colour).
- Are physiological based pharmacokinetic models available for DOTP?
- Recently, physiological based pharmacokinetic models (PBPK) were published for DINCH (McNally et al., 2019) and for two ortho-phthalates, DINP (Campbell et al., 2020) and di-propyheptyl phthalate (DPHP, McNally et al., 2021). We understand that a model for DOTP also is under development.
