- What phthalates are used in PVC & PP?
- Phthalates targeted in this study are namely: benzyl butyl phthalate (BBP), diethyl phthalate (DEP), dimethyl phthalate (DMP), bis (2-ethylhexyl) phthalate (DEHP), di-n-octyl phthalate (DNOP) and di-n-butyl phthalate (DBP) in PVC and in PP. Other commonly used phthalates were also evaluated to ensure method selectivity and specificity.
- How accurate are phthalates and DEHT in PVC?
- An accurate method for 11 phthalates and DEHT in PVC was developed and validated. The developed method has high-order metrological quality. The developed method was successfully applied to analysis of real-life PVC products. Phthalates are mainly used as plasticizers in polyvinyl chloride (PVC).
- How many phthalates are present in PVC?
- In this study, we have developed and validated an analytical method for the accurate determination of 11 representative phthalates, including both regulated phthalates and the non-phthalate plasticizer di (2-ethylhexyl) terephthalate, in PVC.
- Which PVC CRMs are used for phthalate analysis?
- Notably, our laboratory at the Korea Research Institute of Standards and Science (KRISS) has developed and disseminated PVC CRMs (CRM 113–03–006 and CRM 113–03–007) for phthalate analysis, providing certified values for six phthalates: diethyl phthalate (DEP), dimethyl phthalate (DMP), DEHP, DBP, BBP, and DnOP.
- What chromatographic conditions are used for phthalates eluted before DEHP?
- For all compounds eluted before DEHP, including DEHP, the chromatographic conditions used for the quantification of phthalates in medical devices are identical to those developed for the determination of the same compounds in cosmetics (same chromatographic column, same injection conditions, same solvent, same ISTD, etc.).
- How to extract phthalates from PVC?
- Ultrasonic extraction (UE) method was modified from the methods described in literature for extracting phthalates from PVC [33, 39-40]. THF dissolution was followed as described in literature with THF at room temperature for PVC [17,30,37,40-41] and with heated THF for the PP matrix.
