One of the most common questions in soap making. Why does the scent fade in my soap?
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% !
Here are some of my tried and tested essential oil blends that work in cold process soap making.
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.

The whole topic of blending essential oils is huge. It can also be an extremely costly exercise in wasted ingredients and batches that have not turned out as you had hoped. As a soap coach and mentor I often find this to be the biggest hurdle for many of my students and yet it is a topic that can often be demystified in a 30 or 60 minute discussion and if you are looking to create blends for selling in particular investing in some help in this area can be incredibly helpful. If this interests you then take a look at booking onto one of my one to one Zoom sessions, they start at just 30 minutes up to 2 hours and I can cover a lot of information in that time, about all things soap, not just essential oils.
