DTDP plasticizer | ExxonMobil Product Solutions
DTDP plasticizer DTDP plasticizer Jayflex DTDP plasticizer is the highest-molecular-weight phthalate plasticizer, providing greater performance at high temperatures. It is an optimum plasticizer for automotive cable applications and THHN/NMB* electrical wire insulation.
Multi-pathway human exposure assessment of phthalate esters
The estimated daily intakes of total phthalates (n = 7) by children and toddlers through indoor dust in childcare facilities were 1.6 times higher than the non-phthalate plasticizers (n = 3), whereas estimated daily intake of total non-phthalates for all age groups at homes were 1.9 times higher than the phthalate plasticizers.
Molecular Toxicity Mechanism of Plasticizers in the Reservoir
In Europe, about 1,150,000 metric tons of high-volume plastic monomer were produced in 2005–2006 . Structurally, PAEs have a central ring with two esters, which vary with molecular weight. Longer chains have high molecular weight and possess a higher residence rate in the reservoir environment .

PHTHALATES AND HUMAN HEALTH - Occupational and Environmental
High molecular weight phthalates (for example, di(2-ethylhexyl) phthalate [DEHP], di-isononyl phthalate [DiNP], di-n-octyl phthalate [DnOP]), are primarily used as plasticizers in the manufacture of flexible vinyl which, in turn, is used in consumer products, flooring and wall
- Why do alternative plasticizers have lower dust-phase concentrations than phthalates?
- The lower dust-phase concentrations of alternative plasticizers compared to phthalates may be attributed to their larger molecular weight , , . As listed in Table 1, alternative plasticizers generally have larger molecular weights, which correspond to lower vapor pressures and lower y0 on source surfaces.
- Why do phthalates and alternative plasticizers have different mass-transfer characteristics?
- As SVOCs have significant partition capacities on gas-solid interfaces, phthalates and alternative plasticizers exhibit mass-transfer characteristics that differ from other pollutants, such as volatile organic compounds and nanoparticles, which have smaller and larger molecular weights, respectively.
- What are phthalates physico-chemical properties?
- According to the physico-chemical properties, phthalates are water-insoluble, lipophilic, colorless liquids. Based on the length of side chains phthalates are mainly classified into low molecular weight (LMW) and high molecular weight (HMW) compounds.
- Are alternative plasticizers more dangerous than phthalates?
- In contrast to phthalates, alternative plasticizers were reported less frequently and had lower dust-phase concentrations , . DINCH and DEHT were the top two alternative plasticizers of concern due to their high detection rates (see the dust sheet of Supplementary Material B for details).
- How are phthalates and alternative plasticizers classified?
- Based on the classifications of plasticizers, the total concentrations of phthalates and alternative plasticizers were summed separately for source, gas, particle and dust phases. The data were further categorized by continent and sampled years to explore variation trends.
- What is plasticizer phthalate?
- Plasticizer phthalate is a pollutant. Its teratogenic or carcinogenic effects on human. Phytotoxic effects of phthalate and its transmission through food chain. Abatement of phthalate via bioremediation. Microbe-mediated soil-phthalate bioaugmentation approaches.
