The Epoxidized Vietnam Rubber Seed Oil as a Secondary Plasticizer
The epoxidized rubber seed oil (EeRSO) was a mixture of epoxidized triglyceride, and epoxidized methyl ester of free fatty acids was used as a secondary plasticizer for PVC. An increase in tensile properties was observed by substituting the 10 phr DOP plasticizer with the EeRSO in PVC formulation. A leaching test was performed in five media to evaluate the plasticizing effect. The sample
Alternative Plasticizers As Emerging Global Environmental and Health
We start with a pre-screening based on function-related decision rules, followed by three progressive tiers from (1) rapid risk screening of various alternatives for the consumer use stage, to (2) an assessment of chem. supply chain impacts for selected alternatives with substantially different synthesis routes, and (3) an assessment of product life cycle impacts for alternatives with
SCREENING ANALYSIS OF SELECTED PLASTICIZERS AS EMERGING SUBSTANCES
Di-Isononyl Phthalate, is already on the NORMAN list of emerging substances and di(2-ethylhexyl) phthalate, which is on the list of WFD priority substances, both detected in all samples which confirms statements on its ubiquitous presence. CONCLUSIONS Screening analysis of selected plasticizers as emerging substances in the surface waters

are made, they had to be shaped before testing. A manual punch press was used for this purpose. The tensile samples and cylindrical blocks are allowed to stabilize at 25°C and RH of 50% for 72 hours before they are subjected to analysis. 2.2.2. Testing Methods. Tensile strength of samples was determined according to ASTM D638 standard by using
- Are emerging plasticizers a regrettable substitution?
- This review compiles available data on toxicity, exposure, environmental effects, and safe production of emerging plasticizers. It identifies gaps in scientific research and provides evidence that emerging plasticizers are potential cases of regrettable substitution.
- Are emerging/alternative plasticizers harmful?
- Various emerging/alternative plasticizers entered the market following the ban on several phthalate plasticizers because of their harmful effects. However, there are limited data (especially peer-reviewed) on emerging plasticizers’ toxicity and environmental impact.
- Why are plasticizers a problem in Asia?
- Asia holds the second largest share of freshwater (28%) in the world. The Asia-Pacific region is a hotspot for plastic pollution, mainly due to the mismanaged plastic wastes that find their way into the ocean. Hence, it is inevitable for widely used plasticizers such as phthalic acid esters (PAEs) to be present in the aquatic environment.
- How big is the global plasticizer market?
- It has been estimated that the global plasticizer market is expected to grow from 13 967.9 million dollars in 2018 to 16 700.6 million dollars in 2024, (75) thereby indicating the potential magnitude of this emerging environmental problem.
- Are there alternative plasticizers?
- There are a considerable number of alternative plasticizers in employment, without any toxicological data available (dibutyl adipate, diethylene glycol dibenzoate, and bis-2-ethylhexyl sebacate, to name a few).
- What is a PAE plasticizer?
- PAEs are a type of general plasticizer and represent 65% of the worldwide plasticizer market with a significant contribution from bis-2-ethylhexyl phthalate (DEHP), diisobutyl phthalate (DiBP), and diisononyl phthalate (DINP).
