About Essence Authority

Practical explanations for essential-oil product questions, room scenting, fragrance calculations, cleaning, candles, and packing.

Find the next useful step

Start with the question in front of you: what a label means, how a percentage is calculated, which product document you need, or what to write in a test or packing record. Guides explain the task, work through an example, and link to a worksheet where one helps.

Choose a task or search by product, oil, or question.
