diethyl phthalate: what is it and where is it used?,diethyl phthalate (c12h14o4), or DEP is a diethyl ester of phthalic acid. DEP is used as a plasticizer in consumer goods, including plastic packaging films, cosmetics, solvent for fragrances, a surface lubricant in food and pharmaceutical packaging, and in tubing used for medical purposes.

aug 1, 2023 · as a plasticizer, DEP is added to polymers, especially polyvinyl chloride (pvc), to increase their flexibility, softness, and durability. this allows pvc to be molded into various shapes and used in diverse products such as flexible hoses, cables, synthetic leather, and vinyl flooring.
accurate determination of 11 representative phthalates and di,nov 22, 2023 · in this study, we developed an accurate and simultaneous method for determination of 11 representative phthalates and a non-phthalate plasticizer (di (2-ethylhexyl) terephthalate, deht) in pvc as a higher-order reference method.

nov 1, 2022 · the present study seeks to determine the effect of storage and labelling on the levels of phthalates dimethyl phthalate (DMP), diethyl phthalate (DEP), dibutyl phthalate (DBP), benzyl butyl phthalate (bbp) and di(2-hexylethyl) phthalate (dehp) in hdpe packaged water.
diethyl phthalate,diethyl phthalate (DEP) is a phthalate ester. it occurs as a colourless liquid without significant odour but has a bitter, disagreeable taste. it is more dense than water and insoluble in water; hence, it sinks in water. diethyl phthalate is produced by the reaction of ethanol with phthalic anhydride, in the presence of a strong acid catalyst.
- 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.
- Do phthalates soften PVC?
- “Phthalates work as ‘plasticizers’ to help soften PVC,” Dr. Taylor explains. “Manufacturers use it to create flexible plastic products such as shower curtains, food containers and medical tubing.” Phthalates are also found in personal care products, including soaps, cosmetics and deodorants.
- Can phthalate terephthalate be used as a higher-order reference method?
- In this study, we developed an accurate and simultaneous method for determination of 11 representative phthalates and a non-phthalate plasticizer (di (2-ethylhexyl) terephthalate, DEHT) in PVC as a higher-order reference method.
- Are cosmetics phthalate-free?
- You may find products labeled “phthalate-free.” (That makes it easy.) But labels rarely advertise that a product contains phthalates, says Dr. Taylor. Still, you can find specific phthalates listed as ingredients. The U.S. Food and Drug Administration (FDA) requires all cosmetics to include an ingredient list on the packaging.
- 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.
