How to Blend Essential Oils – how many drops should I use?

A simple and creative way to bring essential oils into your everyday life is to add them to daily house hold products.  Something like a shower gel, or face cream would be ideal or even fabric conditioner. Choose something fragrance free or with a natural or mild perfume, otherwise the essential oils you choose may not be noticeable above the fragrance already present or if essential oils are already in the ingredients, adding more could increase the ratio to more than is safe.

Once you have your chosen base, add some of your favourite essential oils to the product and mix them in (see below for inspiration or click here to choose from the range of essential oils). It’s important to know how much essential oil to use because they can irritate the skin if not diluted appropriately.

I have put together 2 charts to help you with this (and a more comprehensive one at the end of the article for when you feel more confident), the first is for general use (which gives a 2% blend strength), and the second for any products being used on sensitive skin, or more delicate skin such as very young or aged skin (which gives a 1% blend strength).

2% General blend strength
Amount of base product No. of drops of essential oil to add
10ml 4
30ml 12
50ml 20
100ml 40
1% Delicate blend strength
Amount of base product No. of drops of essential oil to add
10ml 2
30ml 6
50ml 10
100ml 20

How to mix essential oils into your chosen products:

Sometimes it’s easy enough to remove the cap, add the appropriate number of drops to the bottle and give it a shake to disperse the oils evenly.  I often use a chopstick to stir in essential oils to a pot of cream.  If you have something very thick in a container that you can’t stir through, you may need to pour the product into a mixing jug first to blend the essential oils thoroughly, and then pour back into the original container -a funnel is particularly useful here.  You may also notice that the product becomes a little thinner when the essential oils have been added -this is normal.

Every day body care products and household products you can add essential oils to:

These are some every day products you can easily enhance with a few drops of essential oil, and some suggestions that would work well with their intended use -make sure the original product is fragrance free (organic, natural and children’s products are often more gently scented):

  • Shampoo ~ Rosemary and orange (for dark or thin hair), or chamomile and lemon (for fair hair)
  • Conditioner ~ Rosemary and orange (for dark or thin hair), or chamomile and lemon (for fair hair), benzoin and orange (for all hair types)
  • Shower Gel ~ Lemon and lavender (detoxifying & cleansing), eucalyptus and peppermint (clearing and invigorating).
  • Bubble Bath ~ Lavender and mandarin (cleansing & calming), roman chamomile and neroli (soothing and very calming).
  • Hand soap ~Lavender (cleansing) or rose (nurturing).
  • Face cream ~ Rose and frankincense (for dry, mature skin) or chamomile and neroli (soothing and gentle for sensitive skin).
  • Body cream ~ Benzoin and mandarin (protective and nourishing), geranium and rose (balancing and nurturing).
  • Washing Up Liquid ~ Lavender (cleansing) or basil and lime (fresh and zingy).
  • General Surface Cleaner ~ Lemon or citronella (detoxifying).
  • Bathroom Cleaner ~ Lemon, peppermint, eucalyptus and/or thyme (detoxifying and powerfully anti-microbial).
  • Laundry Liquid ~Lavender (cleansing) and lemon (detoxifying).
  • Fabric Conditioner ~ Lavender (cleansing) or geranium and orange (balancing).

Caution: Because many of these products are usually already fragranced, I would recommend you choose a fragrance free version, or something with a very gentle scent that you can enhance with additional essential oils.   A brand called Urtekram do a perfume free range that would be suitable.  Children and baby products are often fragrance free, and can be gentler with less aggressive ingredients, although this is not always the case.  Organic and sensitive skin ranges may also be fragrance free.

Tip: If I have any essential oils that are past their best then instead of throwing them away I use them in cleaning products around the house.
