Directions for use:
Always dilute essential oils properly before use. Base oils and alcohol are both good for dilution.
Dilution rates will vary by age of the individual and application of the oil.
.25% - for children 3 months to 2 years
1% - for children 2-6 years, pregnant women, and individuals with challenged or sensitive immune systems, and facial use
1.5% - children ages 6-15
2% - for most adults for general use
3%-10% - focused use on smaller areas of the body for therapeutic purposes
10-20% - perfumery level dilution, for small areas of the body and very temporary use on larger areas such as muscle injury
6 drops of essential oil per 1 oz carrier oil is a 1% dilution
12 drops of essential oil per 2 oz carrier oil is a 2% dilution
Citrus oils in particular can be phototoxic, which means they can darken the skin and cause burning of the skin faster than normal when exposed to sunlight. In order to avoid this effect with citrus oils use them below 4%, and preferably use them at times when the skin will not be subsequently exposed to sun.
If irritation occurs discontinue use. Keep essential oils stored in a cool location out of sunlight to best preserve them.
