    I’ve never made a soap before but I noticed there is nothing to neutralize the stearic acid since you replaced TEA… Why did you replace TEA with ethanol? What functions do you think they have in common? Ethanol will not neutralize anything.

    To get a stearate salt, which will be more transparent in solution (stearic acid by itself is bright white), you need to neutralize your stearic acid with something

    @Romis A lot of corrections are needed as i see : Actually stearic acid make soap creamy and decrease the transperency of soap so for the transperency you need high soluble oil as coconut oil , you need also to reduce greasy % and to modify % of solvent respecting the following % in pic.
     for having solid soap you should use between 40% and 60% saturated oil better 50 % however  you have just  (18/48 saturated oil ) so i suppose to decrease the % of SLES and increase the % of saturated oil to have harder bar.
     About changing TEA to ethanol that prouves that you need to learn more about soap so TEA can be solvent right but it play also as Alkalin ” Neutralizer of oils” so if you change it by ethanol you must add an adequat amount of NaOh.
     wish that all is clear unless you are welcome for more explain.
