The effects of phthalate ester exposure on human health: A
Phthalate esters (PAEs) are one of the most widely used plasticizers in polymer products and humans are increasingly exposed to them. The constant exposure to PAEs-contained products has raised some concerns against human health.
A Strategy for Nonmigrating Highly Plasticized PVC - Nature
Phthalate esters are still the most powerful plasticizers and dominate the plasticizer market due to their great plasticizing effect and low-cost, although phthalate plasticizers can migrate to
Phthalate
Phthalate esters are the di alkyl or alkyl aryl esters of phthalic acid (also called 1,2-benzenedicarboxylic acid, not be confused with the structurally isomeric terephthalic or isophthalic acids); the name "phthalate" derives from phthalic acid, which itself is derived from the word "naphthalene".
Bioplasticizer - an overview | ScienceDirect Topics
A PVC plasticizer based on the pentaerythritol ester prepared with predominately C5 acids plus lesser amounts of C7 and C9 acids was patented in 1995 [41] as a low smoke plasticizer. The pentaerythritol ester prepared from C5 acids [42] is now being promoted by the Perstorp Group as a new phthalate alternative under the product brand Pevalen.
Monitoring of DOTP production via esterification with inline
Phthalate esters (e.g., di-2-ethylhexyl phthalate DEHP and diisononyl phthalate DINP) are the main type of plasticizers used to modify PVC and accounted for 65% of global plasticizer consumption in 2017.
- Are phthalate esters released from plastic pipes?
- Phthalate esters (PAEs) are commonly released from plastic pipes in some water distribution systems. Here, we show that exposure to a low concentration (1–10 μg/L) of three PAEs (dimethyl phthalate...
- Do phthalate esters promote Pseudomonas biofilm formation?
- Phthalate esters (PAEs) are commonly released from plastic pipes in some water distribution systems. Here, we show that exposure to a low concentration (1–10 μg/L) of three PAEs (dimethyl phthalate (DMP), di-n-hexyl phthalate (DnHP), and di- (2-ethylhexyl) phthalate (DEHP)) promotes Pseudomonas biofilm formation and resistance to free chlorine.
- What are phthalate esters used for?
- Phthalate esters are used as plasticizers. Phthalate esters are used to prepare in harsh conditions, at a higher reaction temperature. FeCl 3-catalyzed esterification of alcohols with phthalic anhydride affords phthalate esters, under mild conditions. Phthalates are esters of phthalic anhydride.

- Technol. 2022, 56, 2, 1081-1090 Article link copied! Cite this: Environ. Sci. Technol.2022, 56, 2, 1081–1090 Phthalate esters (PAEs) are commonly released from plastic pipes in some water distribution systems.
- Are all plasticizers phthalates?
- They are mainly used as plasticizers, i.e., substances added to plastics to increase their flexibility, transparency, durability, and longevity. They are used primarily to soften polyvinyl chloride (PVC). While phthalates are commonly used as plasticizers, not all plasticizers are phthalates.
- Are phthalate esters a good plasticizer?
- Being inexpensive, nontoxic (in an acute sense), colorless, noncorrosive, biodegradable, and with easily tuned physical properties, phthalate esters are nearly ideal plasticizers.
