Chemists develop safe alternatives to phthalates used in plastics
Researchers have developed safer alternatives to the phthalate plasticizers used to enhance the suppleness, flexibility, and longevity of plastics. Phthalates leach out of plastics into food
A Strategy for Nonmigrating Highly Plasticized PVC
Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as
Plasticizers – Benefits, Trends, Health, and Environmental Issues
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto
Leaching of the plasticizer di(2-ethylhexyl)phthalate (DEHP)
Plasticized PVC is used in hospital equipment, food wrapping, and numerous other commercial and industrial products. Unfortunately, plasticizers can migrate within the material and Di(2-ethylhexyl)phthalate (DEHP) is a widely used plasticizer to render poly(vinyl chloride) (PVC) soft and malleable.
Prevention of plasticizer leaching out of PVC products
Prevention of plasticizer leaching out of PVC products. An elegant approach to internally plasticized PVC, with the main goal of prevention plasticizer leaching. Polyvinyl chloride (PVC) is one of the most widely utilized plastics. It is found in a wide range of consumer products as well as in construction materials and in many medical devices.
- What is nonmigrating highly plasticized PVC?
- Nonmigrating highly plasticized PVC was prepared based on a new compound that acts as a plasticizer that was derived from di (2-ethylhexyl) 4-hydrophthalate and chlorinated paraffin-52. The as-prepared PVC has a plasticizing efficiency as high as DOP and its migration is totally suppressed.
- Are plasticizers harmful to the environment?
- Importantly, plasticizers lack chemical bonds with the products to which they are added, potentially enabling them to leach into the environment; once released, phthalates can contaminate soil, water, and air.
- Do branched and linear nonmigratory internal Plasticizers make modified PVC more flexible?
- Branched and linear nonmigratory internal plasticizers attached to PVC were investigated, the increasing molecular weight and branching of the alkyl ester chains of internal plasticizers makes the modified PVC materials more flexible .
- Which plasticizer has a low plasticizing efficiency?
- Polymeric plasticizer generally has low plasticizing efficiency. Navarro et al. 35 replaced the chlorine on the PVC backbone via nucleophilic substitution of thiol groups attached to the benzene ring of di (2-ethylhexyl)phthalate (also known as dioctyl phthalate, DOP, the most common plasticizer), to give totally nonleachable PVC.
- Is hyperbranched poly (-caprolactone) a nonmigrating alternative plasticizer for phthalates?
- 17.Choi J, Kwak SY. Hyperbranched poly (ε-caprolactone) as a nonmigrating alternative plasticizer for phthalates in flexible PVC. Environmental science & technology. 2007;41 (10):3763–3768. doi: 10.1021/es062715t. [DOI] [PubMed] [Google Scholar]
- Can microbes mitigate plasticizers from the environment?
- This suggests that naturally occurring microbes are capable of mitigate the plasticizers from the environment. Changes in microbial communities and the fate of plasticizers in sediment offer important insights into the lasting environmental effects of microplastic contamination.
