OVERVIEW

Screening for residual solvents is only applicable to hemp products made using a solvent-based extraction method. The amount of residual solvent left in a hemp concentrate should be shown to be below the allowable limit in milligrams, which varies for each applicable solvent.

WHY IT MATTERS

Concentrated hemp products made using a solvent should be purged at the end of the extraction process. Trace amounts of the solvent used can remain even after purging, and high concentrations of certain solvents can be harmful if consumed. Screening products for residual solvents helps ensure consumer safety.
