Single Oil Soap – Hydrogenated Soybean Oil 3

What have you thought about the single oil soaps? Have you learn a lot? I know I have. I wanted to test another highly popular oil in soap making. Today I will be testing Hydrogenated Soybean Oil. Come join me in the test kitchen for this next single soap!


I didn’t have any problems when mixing this soap. It went smoothly with no accelerated trace. When I went to cut my soap after 24 hours, it was very firm. It also crumbled a little when I cut the soap. It made a nice hard, white creamy bar.

When I went to the sink to test this soap it was very creamy. There were some bubbles but not anything I would classify as lather. I do like how hard the soap was but I am not a fan of how it crumbled when I cut it. Otherwise, I think it made an excellent bar of soap that cleaned and was also creamy. What do you think of a bar like this?

    I found all hydrogenated soy oil soap, at 8% lye discount, to be hard on the outside and soft on the inside… even after 4 weeks cure. Nice and white, tho.

    Hi, I am a soaper, fairly new but have been testing recipes, I live in L.A., I can not find hydrogenated soybean oil, where can I find it? What brand did you use and was it in your local supermarket?? Is it liquid or solid?

      Try your local supermarket. Use a brand of shortening that includes vegetable oils only. The saponification value will be very similar.
