Method: LC-MS/MS (Liquid Chromatography/Tandem Mass Spectrometry) with creatinine normalization by Jaffe Reaction (CLIA 17D0919496); not cleared or approved by the FDA. Results reported in µg/g creatinine. Not a stand-alone diagnosis; should be interpreted in clinical context.
Ethyl-paraben is a synthetic preservative widely used in cosmetics, toiletries, pharmaceuticals, and certain foods since the 1920s.
Key benefits of Ethylparaben (EtP) testing
- Ethylparaben personal care product exposure tracking
- complements methylparaben for total paraben burden assessment
What is Ethylparaben (EtP)?
Ethylparaben (EtP) is a paraben preservative used in cosmetics and some food additives. Less prevalent than methylparaben in most individuals but regularly detected alongside it. Measured via LC-MS/MS.
Why is Ethylparaben (EtP) important?
EtP often appears alongside methylparaben in multi-paraben preservative blends. Tracking EtP in context with the full paraben panel provides a more complete picture of total paraben body burden from consumer product use.
What insights will I get?
Your EtP level - reviewed with the other parabens in this panel - may indicate the breadth of paraben-containing product use. A combined review of all four parabens may guide product selection for members seeking to reduce overall paraben exposure.
