Solvent Polarity

Solvent polarity is a chemical property describing a solvent's ability to dissolve polar or non-polar compounds, measured on a scale from non-polar (hydrocarbon-like) to highly polar (water-like). In cannabis extraction workflows, solvent polarity directly influences which plant compounds—cannabinoids, terpenes, lipids, waxes—are selectively dissolved during processing. Ethanol, for example, is moderately polar and captures a broad spectrum of plant material, while hydrocarbons like butane are non-polar and preferentially extract lipophilic compounds. Understanding solvent polarity is essential for breeders and processors evaluating extraction efficiency, final product composition, and consistency across batches. Different extraction goals (full-spectrum, isolate, distillate) rely on deliberate solvent-polarity choices.

Breeders working with extraction-focused cultivars consider terpene and cannabinoid profiles in relation to likely extraction methods; higher sesquiterpene or monoterpene loads may behave differently under polar versus non-polar solvents. Seed selection and phenotype stabilization sometimes account for plant lipid profiles and resin composition, which interact predictably with solvent-polarity pro
