Machine learning-assisted non-destructive plasticizer identification
Diisobutyl phthalate (DIBP) was found in only 2 objects and was quantified using DBP as standard, as the flame ionization detector gives a response proportional to the number of carbon atoms....
Phthalates leaching from plastic food and pharmaceutical
Phthalates are often used as plasticizers in the production of plastic food contact materials (FCMs) and pharmaceutical contact materials (PCMs), and having in mind that they are not bound to plastics, phthalates may easily leach from plastics under certain conditions.

Portable Raman Spectroscopy for Screening of Phthalate Plasticizers
In addition to food contact tubing, the developed methodology is applied to plasticizer analysis in bottle cap gaskets. Portable detection of phthalates in food contact materials is important, as it alleviates the need for high cost and time-consuming laboratory-based testing while allowing for rapid, on-site detection of plasticizers.
Toxics | Special Issue : Phthalate Exposure: From Quantification
Phthalates, the diesters of phthalic acid, are industrial chemicals widely used in commercial products. The ubiquitous use of phthalates results in human exposure from food, dermal absorption, inhalation, and parenteral use of medical—in addition to possible occupational—exposure.
- How to analyze phthalates in plastic?
- Traditional methods for the analysis of phthalates in plastic such as Soxhlet or microwave assisted solvent extraction are time consuming and use vast amounts of organic solvents.
- Which GC-MS analysis system is suitable for phthalates in plastic samples?
- Thermo Scientific Pyrolyzer/thermal desorption GC-MS analysis system composed of a Thermo Scientific ISQ 7000 GC-MS, coupled with a Thermo Scientific TRACE 1310 Gas Chromatograph and a Frontier EGA/PY-3030D multi-shot Pyrolyzer system, is a suitable analytical solution for the analysis of phthalates in plastic samples.
- What are phthalates used for?
- Phthalates are often used as plasticizers in the production of plastic food contact materials (FCMs) and pharmaceutical contact materials (PCMs), and having in mind that they are not bound to plastics, phthalates may easily leach from plastics under certain conditions.
- What is an example of phthalate analysis?
- Examples of samples for phthalate analysis A standard PVC substrate (1,000 mg/kg) was weighed to 0.50 mg (accurate to 0.01 mg) and analyzed as detailed to produce a single-point calibration curve.
- What phthalate is used in PET bottles?
- Phthalates are used principally as plasticizers in polymers to modify its flexibility, workability and durability . PAEs most commonly found in PET bottles are dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), benzylbutyl phthalate (BBP), bis (2-n-ethylhexyl) phthalate (DEHP) and di-n-octyl phthalate (DNOP) [12, 13].
- How to determine plasticizers in polymers before a polymer analysis?
- The extraction is a crucial step for the determination of plasticizers in polymers before their analysis . During this stage, PAEs should be separated from the polymer matrix and isolated from other plasticizers to minimize interferences.
