Using Blended Base Oils
by Mimi

I was wondering how blended oils should be run through a lye calculator. I have a 90% canola and 10% olive oil blend. Should this be considered 100% canola (unblended)?
If a recipe calls for 30% olive oil, how can I use this blend to satisfy that percentage? I was thinking that I needed to add more olive oil. Please help. I am really confused about this blended oil. I am going to try the cocoa and shea butter soap recipe found on your website. Thanks!
Answer:I believe you will have to do some creative math...dividing the 270 grams of olive oil that the recipe calls for into 90% canola and 10% olive. ie. 243 grams canola and 27 grams olive. Use these figures to run the recipe through the lye calculator to get the correct amount of lye.
Then just pour the 270 grams of your blend...the math is just to get the correct amount of lye for the recipe.
Be aware that I've not soaped with canola myself so I don't know how the recipe will work out using this blend.
Good luck,
