Thanks Belassi, the surfactant is the ingredient missing that I’m trying to fix with the formula. Do you have any recommendation? I’ve heard these information about phosphate.. I’ll be careful and used only if needed at the minimum concentrations allowed. Very appreciated for the links .

Bobzchemist thanks for the info. It is not the final list of ingredients mainly because the most important ingredient (surfactant) is missing… I hope to find the optimum one.

Thanks for you help! Here are the details:

 

Ingredients: olive oil, phosphate salt, stearic acid, sodium stearate and bee wax. I do not have the percentages of the ingredients yet.. 

Belassi, what do you mean by a natural soap bar? I guess in my case is synthetic, as all ingredients are synthetically produced except the olive oil and bee wax.
