Hello Dear, thanks. I tried with Babassu oil, but it’s no good. It doesn’t make a lot of foam.

Do I need to increase the estearic acid? Can you help me.

I tried to get on the internet, but they do not speak a value, just 10 to 30 % of stearic acid. Wasn’t white, got a little transparent

My Formulation is:

stearci acid - 7,50 %
Miristic Acid - 11,50%
Babassu OIl -9,5%
Glicerin - 5%
KOH - 5,30%
NaOH - 0,30%
triethanolamine -1%
water - qsp

Sodium Lauroyl
Sarcosinate………………………..
3,00

Your Stearic Acid content it not high enough. Your Babassu (similar to Coconut Oil and used for lather) is too high and so is your Myristic Acid. Basically, your ingredients aren’t too bad but the amounts aren’t in the right ranges for each.

Dear Mr David. Thank you very much for your help!! Very Kind.

In my country don’t find coconut fatty acids. Can I keep the Babassu oil or Coconut Oil in the same quantities?

Yes, you can substitute the Babassu or Coconut Oil in the 4.5 to 5% range for the Coconut Fatty Acids (4.8% in this formula). You really only need to lower the Myristic Acid 1% or 2% to get into the range in this formula. The biggest change will be the Stearic Acid which is about a third of what it should be. That is a major reason your results are clear and not white!
