Solvent free

A concentrate made with solvents that have been purged out to non-detectable levels. Solvent-free concentrates differ from solventless concentrates, which are made without solvents. Any concentrate made with a solvent can be purged to be solvent free, though solvent-free concentrates are often oils.
