A Working Definition for Founders<\/b><\/span><\/h2>

\"What are essential oils?\" is a question every new brand founder must answer precisely. The marketing answer - \"natural plant aromatics\" - is fine for advertising but inadequate for product development. Technically, essential oils are concentrated, lipophilic, volatile chemical mixtures extracted from plant material. They contain terpenes, terpene alcohols, esters, aldehydes, ketones, oxides, and phenols at concentrations 70-200\u00d7 higher than in the source botanical. They are not lipids; the \"oil\" describes texture and solubility, not chemistry.<\/span><\/p>
