Essential oils, used for everything from insect repellents
to aromatherapy and fragrance, are very strong and need to
be used with care, but they can cause environmental health
problems if the brand doesn’t provide pure oils. Some oils
have petroleum-based solvents added, which can be very toxic.
Petroleum-based solvents are often long-lasting in the
environment, are stored in our fat, and are a source of
volatile organic chemicals (VOCs) that negatively affect
indoor air quality.
Do an easy blotting paper test to see if your oils are pure.
Put a few sample drops of your oils on a blotting paper. Pure
essential oils will not leave any residue once they have
evaporated, whereas petroleum solvents will.
