RESIDUAL SOLVENT TESTING

What is Residual Solvent Testing?

Residual solvents are the solvents (propane, isobutane, n-butane, pentane, hexane, benzene, toluene, xylenes, methanol, ethanol, isopropyl alcohol, acetone, and others) that remain in cannabis oils, shatters, waxes and budders after the extraction process, which strips the cannabinoids and terpenoids from the plant material.

Extraction typically involves passing a liquid or gas over ground-up plant material (flower, trim or shake). Once the combination becomes room temperature, it can be taken through a series of different processes to create various concentrates.

The remaining solvents should be purged from the concentrate using heat, vacuum pressure, or other methods to make certain no harmful residue remains.

What is the Importance of Solvent Testing?

For various reasons, residual solvents are UNSAFE for human consumption, regardless of the processing or consumption method. For that reason, any supplier should and MUST ensure consumer and patient safety prior to sales or distribution.

Propane, n-butane, pentane, hexane, benzene, toluene, xylenes, methanol, ethanol, isopropyl alcohol, and acetone are just some of the commonly-found solvents for which we test.

All responsible concentrate makers should use safe extraction methods in order to produce cannibinoid concentrates that can be trusted with the health and wellness of their patients.
