Plasticizer migration from children's toys, child care
Migration rates correlated roughly with plasticizer concentration and inversely with the molecular mass of the plasticizer. We then combined the migration rates with data on mouthing duration to estimate children's exposure to plasticizers in toys and child care articles, and estimated margins of exposure. All margins of exposure were >1,000

Migration of plasticizers from PVC medical devices
Alternatives to DEHP plasticizers are used in various PVC medical devices (MD) for infusion. As they are able to migrate from these MDs into infused solutions, they may come into contact with patient. Different and specific clinical parameters influence their migration in at-risk situations such as
Migration of phthalate and non‐phthalate plasticizers out
The plasticized PVC (p-PVC) films are obtained by gelation at 160°C for 15 min. The p-PVC films were heat treated at 50, 85, 100, 130, and 160°C up to 420 min to follow the mass loss to find out diffusivity of plasticizer out of films into air and to determine related activation energies.
Diverging trends of plasticizers (phthalates and non
Background European chemicals management aims to protect human health and the environment from legacy and emerging contaminants. The plasticizer market changed in response to the restriction of low molecular weight (LMW) phthalate plasticizers such as Di (2-ethylhexyl) phthalate (DEHP) due to their hazardous properties. We investigated patterns and trends of 19 regulated and emerging
- Do plasticizers migrate from PVC products?
- Due to the tendency of plasticizers like di-2-ethylhexyl phthalate (DOP) and bis (2-ethylhexyl)adipate (DOA) to migrate from PVC products, which pose serious health risks, and have therefore been increasingly restricted in many countries. Enhancing the migration resistance of plasticizers in PVC remains a critical challenge.
- Can flexible PVC be prepared with permanent plasticizer effect and zero migration?
- However, the migration is completely suppressed. This approach may open new ways to the preparation of flexible PVC with permanent plasticizer effect and zero migration.

- Are phthalate plasticizers safe?
- Despite their low cost and favorable performance, phthalate plasticizers exhibit high volatility and poor solvent resistance, making them susceptible to migration from PVC and raising significant safety concerns [9, 10, 11].
- What is the plasticization process of plasticizers in PVC?
- There has been no clear evidence observed regarding the plasticization process of plasticizers in PVC. However, three predominant plasticization theories are widely recognized: the free volume theory, the lubrication theory, and the gel theory [40, 41].
- What are the low migration plasticizers among 3?
- New York, USA. perature.33 Summing up, the FTIR investigations reveal that DOTP and DINCH are the low migration plasticizers among 3. Brebu, M.; Vasile, C.; Rovana Antonie, S.; Chiriac, M.; Precup, M.; Yang, J.; Roy, C. Polym.
- Are PVC plasticizers safe in oily environments?
- Within less than 6 h, the plasticizers had nearly fully precipitated, with mass loss rates significantly exceeding the safety threshold of 5%. Consequently, PVC materials plasticized with DOTP and DOA are unsuitable for use in oily environments. In contrast, E-EOD-50 and E-EHD-50 initially exhibited relatively low migration rates.
