Oil Safety IQ

Oil Safety IQ: how it works

Ten real situations with essential oils. Pick the safe move and see the reason behind every answer you miss. It is part of the free essential oils tools on Natural Knows, and it runs in your browser: no sign-up, and your answers stay on your device.

Each play draws 10 questions from a bank of 30, and the answers are shuffled, so the tool feels new when you come back. After the last question you see your score and a short explanation for every answer you missed.

Three questions from the bank

• How many drops of essential oil go in a 10 ml roller for the face? 2 drops (about 1%). A standard dropper gives about 20 drops per ml, so 10 ml of carrier is about 200 drops. 2 drops is about 1%, a gentle strength for the face.
• What does "therapeutic grade" on a label mean? It is a marketing phrase, not an official standard. No official body grades essential oils as therapeutic. Look for the Latin name, the country of origin and a batch number.
• Which oils can make skin react to sunlight when cold-pressed? Lemon, lime, bergamot and grapefruit. Some cold-pressed citrus oils contain compounds that react with UV light. Steam-distilled or bergaptene-free (FCF) versions avoid it.
