Permethrin Testing at Vartest

Vartest is one of the few labs that are able to deal with both the textile technology and organic chemistry aspects of permethrin testing.

 

Permethrin is the most widely used insect repellent against mosquitoes, ticks, cockroaches, and other pest insects. It is typically applied as a finish to both textile piece goods and finished apparel.

Using gas chromatography/mass spectrometry (GC/MS) based industry standard methods and military specifications, Vartest is able to report the amount of permethrin present on a garment both as a percentage on weight of fabric (OWF) and as a mass per unit area (grams per square meter or ounces per square yard).

 

Vartest is also able to assess the amount of permethrin present on a garment after refurbishment, using both diagnostic and industrial wash formulas as well as dry cleaning.
