Analyze Cosmetics and Personal Care Products for Ethylene Oxide and 1,4-Dioxane With New Restek® Standards

Restek PEG StandardsEthylene oxide and 1,4-dioxane are considered probable carcinogens by the U.S. EPA and International Agency for Research on Cancer respectively. These compounds are impurities in polyethylene glycol (PEG), but because of the potential danger they pose to humans, they must be removed before PEG can be used as a thickener / softener in cosmetics and personal care products.

Restek has formulated the only off-the-shelf suite of reference standards targeted toward the analysis of PEG-based products to make it easier for labs to verify the safety of shampoos, hand creams, and more. Produced with the specific concentrations needed in the industry, these newest Restek® certified reference materials (CRMs) are quantitatively tested to confirm their composition, and detailed support documentation is provided with each purchase. Because they are manufactured and QC-tested in Restek’s ISO-accredited labs, they also help satisfy ISO requirements.

With the release of these new ready-made reference standards, contract labs and manufacturers of PEG-based cosmetics and personal care products no longer need to order custom standards or make their own mixes.

It is also ideal for surface water and groundwater testing inside or outside the U.S.

This new set of reference standards offers a full 82-component EPA 524.3 list using as few as three ampuls to reduce prep time and chances for error or contamination.
