Recent Attempts in the Design of Efficient PVC Plasticizers
Chemical and physical properties of PVC formulations containing a wide range of plasticizers have been compared, allowing observance of the improvements in polymer performance in comparison to PVC plasticized with conventionally applied bis(2-ethylhexyl) phthalate, di-n-octyl phthalate, bis(2-ethylhexyl) terephthalate and di-n-octyl terephthalate.
Dibutyl phthalate
Dibutyl phthalate ( DBP) is an organic compound which is commonly used as a plasticizer because of its low toxicity and wide liquid range. With the chemical formula C 6 H 4 (CO 2 C 4 H 9) 2, it is a colorless oil, although commercial samples are often yellow. [3] Production and use [ edit]

There are two main groups of plasticizers: primary—the main plasticizer in a PVC blend, added in large quantities and highly compatible with PVC; and secondary— having limited...
Phthalate Esters in the Environment: Sources and Quantification
The primary route of human phthalate exposure has been presumed to be ingestion, while the more volatile phthalates can be inhaled. Because phthalate plasticizers are not chemically bound to PVC, they can easily leach and evaporate into food or the atmosphere [5-6]. Phthalate exposure can be through direct use or by indirect
- What is dibutyl phthalate?
- Dibutyl phthalate. Acts as a plasticizer. This ester is produced from the reaction of phthalic anhydride with n-butanol. It causes all the polymeric materials including PVC to soften. It does not... view more
- Does PVC microplastic release phthalate?
- In this study, the release behavior of phthalate plasticizer from PVC microplastics in aqueous solutions was comprehensively studied. We found that particle size, plasticizer content, aging of plastics, and DOM presence had great effects on phthalate release, while solution pH and ionic strength showed minor effect.
- How do plastic properties affect dibutyl phthalate release?
- It was found that plastic properties, such as particle size, plasticizer content and aging of plastics had a great effect on the leaching of dibutyl phthalate (DnBP). Phthalate release was generally higher in smaller particles and particles with higher phthalate content.
- Does dibutyl phthalate release toxic chemicals and risks associated with microplastics?
- In this study, the release of dibutyl phthalate (di-n -butyl phthalate, DnBP), a commonly used phthalate plasticizer, was targeted. The findings of this study would provide valuable information for evaluation of toxic chemicals and risks associated with microplastics. 2. Materials and methods 2.1. Microplastics
- Why is di-butyl phthalate a good plasticizer?
- Its versatility and effectiveness as a plasticizer highlight its importance in modern manufacturing processes, contributing to the production of high-quality and functional products across multiple sectors. Di-Butyl Phthalate (DBP) is a versatile chemical compound widely used as a plasticizer in various industries.
- Which plasticizers contain phthalates?
- Among all plasticizers, phthalates are the most popular ones. Flexible polyvinyl chloride (PVC) products, such as packaging/greenhouse films, toys, medical infusion tubing, wires, cables and flooring materials, may contain a significant amount of phthalates (up to 60% by weight) (IHS Markit, 2021).
