Blending essential oils for soap making is something I get asked about time and time again. Not only do you have to contend with the high PH of your soap chasing away the more flighty citrus scents for example but you also need to think about your scents and how they work together, top, middle and base notes. Cost (a big factor as you do need a fair amount of essential oils and they are not cheap) Plus as if that were not enough to contend with some essential oils can only be used in limited percentages as they can cause irritation.
Phew - the mind does boggle! As a guide EU legislation dictates that you can add up to 3% of your base weight of oils in essential oils. Assuming you are not using one that is restricted - for eg Clary Sage and Peppermint can only be used at a maximum 2%. Clove Bud 0.5% and Nutmeg a teeny tiny 0.08% !
Below I have come up with a few favourite combinations to get you started, you will need to work out quantities depending upon the volume of oils you are using. When we make soap in my soap making workshops the volume of oils we use is 900g so 3% of this is 27g of oils which you can then break down in to parts depending on which blend you like the sound of.
