Pure essential oils can be effective and efficient additions to your aromatherapy, home, and body care creations. However, these powerful plant extracts come with a great responsibility to exercise restraint. A single drop of essential oil contains an incredible concentration of herbal properties, so all this plant potential must be dispersed to levels that are safe for our bodies to process.
As the popularity of essential oils has increased among natural-living and body care enthusiasts, so has the number of inquiries we receive about how to incorporate safe levels of essential oils into homemade creations. While many professional herbalists and natural product crafters have happily shared their insights on this topic in terms of parts, percentages, and ratios, these terms can be confusing and intimidating for those just starting out with their essential oil explorations. That’s why we’ve assembled some simple guidelines and tools to get new users off to an encouraging (and safe!) start.
Essential oils are strong and must be diluted for safe use, whether you plan to use them on their own (usually in a neutral carrier oil) or as ingredients in a finished product such as a massage oil, lotion, or aroma spray. Whichever dilution method you choose, the essential oil content should only account for 0.5% to 2% of the total blend. This equates to 3 to 12 drops per ounce of finished product. For easier versions of all this math, check out our handy charts and calculators below!
For most body care formulations, it is recommended that essential oils make up no more than 2% of your total end product volume. This dilution takes into consideration that creams, lotions, serums, and other products are often applied liberally, frequently, and to large portions of the body, and fragrance is usually a secondary concern to the formula's primary function (moisturizing, smoothing, etc.).
Perfumes containing essential oils are a bit different. Since these formulations are generally applied sparingly and to localized areas, you may choose to use a higher proportion, up to 5%, to allow your aroma blends to shine.
