What is monoethyl phthalate in?
Monoethyl Phthalate (MEP) is a metabolite of plasticizer diethyl phthalate (DEP). Monoethyl Phthalate is a one of the most abundant phthalate metabolites present in human urine. It is also present in other body fluids including breast milk, serum, semen, saliva and amniotic.
Where is monoethyl phthalate found?
Monoethyl Phthalate (or Monoethylphthalate) (MEP) from diethyl phthalate is the most abundant phthalate metabolite found in urine. Diethyl phthalate is used in plastic products. Elevated values indicate exposure from various possible sources.
Is diethyl phthalate hazardous?
► Exposure to Diethyl Phthalate can cause headache, dizziness and nausea. causing numbness, “pins and needles,” and/or weakness in the hands and feet. NIOSH: The recommended airborne exposure limit (REL) is 5 mg/m3 averaged over a 10-hour workshift.
What is phthalate free?
Non-phthalates are essentially plasticizers that are free of phthalates. A few examples of non-phthalates include DOTP (diethylehexyl terephthalate, aka DEHT), Hexamoll DINCH (diisononyl cyclohexane dicarboxylate), as well as bio-based plasticizers, such as a line of soy-based plasticizers.
What is the formula for KHP?
C8H5KO4Potassium hydrogen phthalate / Formula
Are phthalates banned in the US?
A: In 2017, the Consumer Product Safety Commission banned the use of eight ortho-phthalates in children’s toys and child-care articles. But in terms of their use in vinyl plastics and personal care products, there’s currently no specific legislation by other governmental agencies.
How do you identify phthalates?
How do I identify phthalates in products? There is no easy way to tell if a product has added phthalates. Phthalates can be identified on labels by a three or four letter acronym that defines their chemical structures. Labels rarely state “contains phthalates”.
What is diethyl phthalate used in?
Diethyl phthalate is used as a plasticizer in a wide variety of consumer products, including plastic packaging films, cosmetic formulations, and toiletries, as well as in medical treatment tubing. As a result of its use, human exposure to diethyl phthalate is expected to be signi- ficant.

Liver tumors were seen in mice that had diethyl phthalate placed directly on their skin daily for 2 years.
Is PVC the same as phthalates?
A group of plasticizers commonly found in PVC products are phthalates, also called ortho-phthalates. Phthalates are used in PVC and certain other plastics and rubber as a softening agent to make the plastic flexible.
Why is phthalate bad?

Liver and kidney toxicity. Certain phthalates are linked to adverse impacts on the liver and kidney in laboratory animals.
What is the KHP standard?
Potassium hydrogen phthalate (KHP) is a widely used primary standard (functioning as a mono- protic acid) for acid/base titrations. The titration curve in Table 1 shows an example of using KHP to determine NaOH concentration (a process called standardization).
