Migration of plasticizers from poly(vinyl chloride) and multilayer
It is not chemically bound to PVC and may migrate after contact with surfactants or oily agents. Multilayer infusions bags may also release plasticizers as phthalates (dibutyl phthalate, diethyl phthalate) or adhesive as caprolactam (Haned et al., 2018). The use of adequate material for human medicine is therefore of major importance. Show abstract
Migrability of PVC plasticizers - ScienceDirect
The study of the extraction and migration of PVC plasticizers is of great importance for different reasons. Extraction of the plasticizer can occur in PVC films in contact with food, in bags or pipes in contact with biological fluids, such as blood, or even when a child could chew a PVC toy.
Methods for determination of plasticizer migration from polyvinyl
Plasticizer migration is responsible for premature coating failure in polyvinyl chloride (PVC) synthetic materials that continue to benefit our daily life as a reliable and cost-efficient simulant of genuine leather. In this context, the establishment of standard assays that measure the migration rate of plasticizers under varying scenarios plays a pivotal role in comparing durability of those

Migrability of PVC plasticizers from medical devices into a
Migrability of PVC plasticizers from medical devices into a simulant of infused solutions Medical devices (MD) for infusion and artificial nutrition are essentially made of plasticized PVC. The plasticizers in the PVC matrix can leach out into the infused solutions and may enter into contact with the patients.
- Can PVC plasticizers migrate to a polymer in contact with flexible PVC?
- The ability of different PVC plasticizers to migrate towards a polymer in contact with flexible PVC has been investigated. A procedure based on the monitoring of the plasticizer concentration by infrared spectroscopy has been employed.
- Why is plasticizer migration a problem?
- The plasticizer migration from the plastic item to its surroundings may involve the appearance of problems, namely the modification of flexibility of the PVC and the contamination of the media in contact with PVC.
- Do plasticizers migrate from PVC to DOP?
- As expected, the migration of plasticizers was equal to zero. Mechanical properties of the material with modified PVC were compared to a material plasticized by DOP. The commonly used plasticizer provided significantly lower tensile strength and higher elongation at break than the modified one.
- Are PVC plasticizers harmful to patients?
- The plasticizers in the PVC matrix can leach out into the infused solutions and may enter into contact with the patients. In order to assess the risk of patient exposure to these plasticizers we evalu … Migrability of PVC plasticizers from medical devices into a simulant of infused solutions Int J Pharm.
- How do we detect plasticizer migration from PVC synthetic materials?
- To this end, this review is compiled as a general review of the methods now available for detecting plasticizer migration from PVC synthetic materials via three different mechanisms (i.e., volatilization, exudation, and extraction), with an emphasis on the instrumentation, methodology, advantages, and limitations of each method.
- Which plasticizers are used in flexible PVC?
- In flexible PVC formulations, esters derived from phthalic acid are the most common monomeric plasticizers, although other compounds based on various organic acids (phosphates, trimellitates, citrates, sebacates, and adipates) can also be used [6, 7].
