The plasticizer market: an assessment of traditional
Hence, preventing leaching and migration of plasticizers will have considerable impact on the environment as well as human health. 3.4.1. Government regulation of phthalatesThe regulation of phthalates as plasticizers has undergone scrutiny with the concerns over the toxicity and carcinogenic behavior of DEHP.
Study of the migration of PVC plasticizers - ScienceDirect
2.3. Migration test. Small squared strips of polystyrene ( 3 mm ×3 mm) with approximately 1 mm of thickness were placed between two PVC sheets of 2 mm of thickness, and kept under mild pressure (217 kPa) in a oven at 50 °C for 1 week. Plasticizer migrated after this time, was determined by thermogravimetric analysis, in a Perkin-Elmer
Phthalate Plasticizers Covalently Bound to PVC
The internal plasticization of PVC by displacement of chlorine with phthalate-based thiol additives, that is, the covalent attachment of the plasticizer to the PVC chain, is described for the first time. Using this methodology, a good plasticization efficiency is achieved although flexibility is reduced compared with that of commercial PVCphthalate systems. However, the migration is
Phthalates in Food Packaging and Food Contact Applications
The FDA revoked authorizations for the food contact use of 23 phthalates and two other substances used as plasticizers, adhesives, defoaming agents, lubricants, resins, and slimicides.
Migration of plasticizers phthalates, bisphenol A and
Migration of plasticizers phthalates, bisphenol A and alkylphenols from plastic containers and evaluation of risk This study investigates the potential migration of plasticisers, plastic components and additives from several plastic water bottles.
- Do plasticizers migrate better than SML?
- Migration performance of conventional and new plasticizers were investigated. Distinct migration was due to different interactions between the plasticizers. Correlation between migration and tensile properties of the films was done. Most of commercial samples showed migration lower than SML established.
- Do plasticizers migrate into acidic foodstuffs?
- Thus, it has been demonstrated that a contact for prolonged time up to 40 °C did not promote the migration of plasticizers into acidic foodstuffs, but the migration of plasticizers to fatty foods can be high (75%–90% loss of plasticizers) and limit the use of PVC films as fatty food packaging. 1. Introduction
- Are phthalate plasticizers covalently bound to PVC?
- Phthalate plasticizers covalently bound to PVC: plasticization with suppressed migration Correlation of specific migration (Cf) of plastics additives with their initial concentration in the polymer (Cp) Food Additives and Contaminants, 14 ( 6–7) ( 1997), pp. 705 - 719
- Does Mercosur regulate the migration of phthalates from food packaging materials?
- Migration of phthalates, alkylphenols, bisphenol A and di (2-ethylhexyl) adipate from food packaging Plasticizers in Brazilian food-packaging materials acquired on the retail market Mercosur/GMC/Res. n. 32/10. Mercosur technical regulation on migration from plastic materials, packages and equipments intended to come in contact with foodstuffs
- Do plasticizers migrate into food simulants?
- In addition, commercial films have been evaluated as to plasticizers concentration and specific migration into food simulants. It was found that 25% of the samples comply with the specific migration limits for fatty foods contact while 50% might be used for contact with fatty foods with FRF 2–5.
- Which plasticizers produce the highest migration values?
- Therefore, samples formulated with approximately 16% of DEHA (sample 1) and 18% of MGA and AGM – vegetable-origin plasticizers (samples 3 and 5) were the samples that produced the greatest values for overall migration, as can be seen in Fig. 1.
