EO's are "the ancient intelligence of plants". They are medicine as well as a delight to smell, so they are not to be taken lightly, imo. I love eos in soaps but they fade So Fast....I have been experimenting with fos recently....the conclusion I come to is I wish the eos smelled like the fos...
I like the soap very much--regular cure--4-5 weeks and terrific lather. One caveat...in hot and humid weather some of my coconut soaps began to get dossy at two months!! so I wouldnt count this as a long lived soap, alas. The high superfat may have contributed to the issue.
I make a 100% CO with a 20% superfat and I have never had a problem with an oil slick on top...but I make a 3lb loaf...it may be harder with such a small batch..no help at all......sorry! I do make this soap often tho, sometimes use aloe vera juice instead of water and it always behaves well.
