Analytical methods for the determination of DEHP plasticizer
Polyvinylchloride (PVC) is a plastic material which is widely used in fields as diverse as construction, automobiles, cabling, toys, luxury goods, and healthcare. PVC possesses the largest share of the medical market. Almost 30% of all plastic-based disposable medical devices (MDs) used in hospitals are made from PVC, usually as flexible PVC [1

Determination of the Banned Phthalates in PVC Plastic of Toys
To strengthen the control of the quality of toy products and protect children’s health, it is very important and meaningful to study the determination methods of plasticizers in PVC plastics. The pretreatment method of plasticizers in PVC plastics generally used the ASTM D3421-75 (this method had
GC/MS Method for the Determination of Adipate Plasticizers
A GC/MS method was developed and successfully used for the determination of adipate plasticizers in ham sausage samples. All 5 adiapte plasticizers, including DEA, DIBA, DBA, BBOEA, and DEHA, were well separated within less than 18 min of elution without significant interference from the sample matrix.
Plasticizers: Types, Uses, Classification, Selection & Regulation
Plasticizers increase the flow and thermoplasticity of a polymer by decreasing the viscosity of the polymer melt, the glass transition temperature (Tg), the melting temperature (Tm) and the elastic modulus of the finished product without altering the fundamental chemical character of the plasticized material.
- Are plasticizers in children's backpacks and plastic toys a source of dermal exposure?
- This work has measured the mass content of plasticizers that are currently used in children’s backpacks and plastic toys. Product wipes were used to examine the transfer of plasticizers from children’s backpacks and plastic toys, which may be potential sources for dermal exposure to plasticizers.
- How many plasticizer compounds are in a backpack or plastic toy?
- Each backpack or plastic toy contained at least one plasticizer compound with mass content higher than 5%, or 50 mg/g.
- Which plasticizer is used in a backpack and a toy?
- DIDP and DINCH dominated the plasticizer composition in one backpack (ST-b, 14.6±3.71%) and one plastic toy (WA-t1, 22.7±2.43%), respectively. The CPSIA limits the application of DEHP, DBP, BBP, DnOP, DINP and DIDP in children’s toys and child-care articles.
- Do plastic toys contain O-acetylcitrate?
- Other than DEHT, only tributyl o-acetylcitrate (ATBC) and DINCH were identified in plastic toys at mass contents higher than 0.1%. The mass contents of plasticizers in backpacks and plastic toys were comparable to those reported for vinyl flooring (0.1–23%) 4, 23, 24 and crib mattress covers (13.6–15.1%). 25
- Why does a gauze pad wipe a plastic toy?
- One possible reason is that the 3 ml of isopropanol on the gauze pad ran out on the surface of each plastic toy during the wiping process because of the toys’ much larger surface area (155–428 cm 2, Supplementary Tables S4 and S5) compared with the backpack pieces. Thus, the effective wiping time with solvents would have been shorter for toys.
- Do product wipes transfer plasticizers from children's backpacks and plastic toys?
- Product wipes were used to examine the transfer of plasticizers from children’s backpacks and plastic toys, which may be potential sources for dermal exposure to plasticizers. The amount of plasticizers observed on product wipes was correlated with the compounds’ mass content in the product.
