Castile soap

I tried making a 100% olive oil soap just using extra-virgin olive oil, sodium hydroxide and water - 5% superfatting, no fragrances. I used the cold process method. It came to a trace fairly quickly and when it reached a custard-like consistency, I poured it into a mould, covered it and left it on the top of our boiler for two days so that it could keep warm. When I took it out of the mould, it looked almost perfect. Left it to stand for more than five weeks in a dry place, and then tried using it. It is very gentle to the skin and lathers quite well, but tends to go too soft when it comes into contact with water and turns almost jelly-like. Do you think the hot process could yield better results or is it just a matter of waiting longer for the soap to season properly? Could sodium lactate help in improving the consistency of the bars and make them last longer?

As regards the oil

As regards the oil being adulterated, I must say I've got a few doubts myself, seeing that it freezes at a temperature that is too high for genuine evoo. Actually, I bought that oil off some people who live in Apulia who have some olive groves and produce their own oil. Since it had a rather strong taste which I didn't like, I decided to use it to make soap. When I mixed the oil and lye using the stick blender, it came to a trace almost instantly - and a very thick trace too. Anyway, as regards the soap I made, I got fed up waiting and decided to cook it at the end. I also made some other soap with the same oil using the hot process method, and I must say the bars are very hard and long-lasting...so, whatever the oil, the result isn't so bad after all!

It takes up to 6 months

It takes up to 6 months for a 100% olive oil soap to cure completely. I am still waiting on my first CP batch. Being impatient, I went ahead and made a 100% olive oil with goat's milk powder HP batch. I'm giving it 6 weeks to cure so it's not quite ready yet either. :( From the sounds of it tracing quickly, you may have gotten adulterated olive oil. Pomace doesn't seem as slow to trace but evoo definitely is slow. Maybe we just need to keep experimenting. Good luck!   PS Costco's olive oil hasn't tested as adulterated so try Kirkland brand. It has worked fine for me.
