Abstract
Overview
ISO 4715:1978 defines a quantitative laboratory method for determining the evaporation residue of essential oils. The method removes the volatile fraction of an essential oil by heating on a boiling water bath and quantifies the non‑volatile residue by direct weighing. This straightforward gravimetric technique supports routine quality control and purity assessment of essential oils.
