    I’m trying to make my own first recipe. I had castor at 17% but then I read to much castor can make a sticky slimy bar. So I changed it to 5% is that okay or can I add more? I’m using coconut oil 92*, palm oil, castor oil, canola oil and rice bran oil. I’m working on the % of each. I’ve changed it about 25 times now. I’m superfatting at 5% Any help or input is greatly appreciated!

    5% is a good amount for castor oil in soap. Castor helps stabilize lather, but doesn't actually make bubbles itself.

    5%-8% in my book. However I have read of people going as high as 10%. Perhaps one of them will chime in.

    I use 5 to 7% Castor. It doesn't seem to add anything to the mix for me, except to stabilize the lather that I have from the other ingredients.

    I personally hated the soap I made with 10% castor oil. 5% is plenty for me and sugar helps with the bubbles all the more.

    Saponified castor oil in soap is very soluble and helps kickstart the lather from the other saponified oils.

    In general, I'd say keep it under 10%. My limited experience with higher percentages is that it worked fine when I had a relatively high percentage of hard oils as opposed to soft oils (maybe 75:25, but I can't say for sure). It seems like with more soft oils, too much castor made the soap sticky.

    Perhaps a better question than "how much castor can I use" is "why do I want to use a lot of castor"? If you can answer that, then it's easier to evaluate your results. Castor is fairly expensive in the US so a reason is warranted, for me anyway.

    Right here, silly!
    I use it at different levels in different formulas. In my shave formula, which contains a high amount of stearic, I use castor at 20%; in a 65% tallow formula of mine, I use castor at 23%. In my tallow/lard formula that also contains olive oil, hydrogenated PKO, coconut oil and mango butter, I use it at 10.5%. Basically, the more hard fats in my formula, the more castor I find I can use without it making my soap feel sticky.

    I use 5% with 1 tablespoon of sugar per lb of soap.

    5% castor works great for me.

    Any kind of sugar will work fine - granulated or powdered. Add it to your water and let it fully dissolve BEFORE adding your lye.

    Okay what do you all think of my recipe? I changed it.

    Castor 6%
    Cocoa butter 15%
    Coconut oil 92* 33%
    Olive oil 33%
    Rice bran oil 13%

    5% super fat

    Adding sugar to water

    Adding coconut milk I will do a water discount so I can add this.

    I’m working on another one with palm oil.

    If you are using coconut milk as a replacement for all or half of the water, I don't think you need to add sugar - plenty of it in the coconut milk.

    Last time I made a bar with 33% coconut oil I found it too drying unless I bumped up the superfat to about 6-7% BUT again - the coconut milk will also add some additional SF so you may be ok with a 5% superfat. Try it and see.

    I'm confused my coconut milk says 0 sugar? I’m also only using about 2oz of the milk for hp.

    Coconut milk does not have any ADDED sugar. There are natural carbohydrates in the coconut milk. Look at the "total carbohydrates" amount.
