Residual solvents[rɪˈzɪdjʊəl ˈsɒlvənts]
Residual solvents are substances leftover from the extraction of cannabinoids and terpenes from plants. These solvents need to evaporate to make high-concentration oils and waxes. The solvent may not be completely removed during the evaporation process. Because these solvents are not suitable for human consumption, it is critical to check for their absence to ensure suppliers deliver a chemical-free product.
Solvents are divided into three categories: Class 1, Class 2, and Class 3. Among them, class 3 solvents are the ones recommended to prepare Cannabis extracts since they have a low toxic potential.
