Residual Solvent Contamination

In today’s market, you have to compete with every type of product from concentrates: waxes, oils, shatters and salves. With such product diversity, it is vitally important to ensure safety across all of your lines.

Products purified with organic solvents must be tested to ensure that remaining or “residual” solvents in manufactured products are within safe consumption levels. Colorado currently requires residual solvent testing for butanes, heptanes, benzene, toluene, xylenes and hexane to be within acceptable limits per gram of product.
