Hi this question is kind of tricky which I may not answer to my panelist in my thesis.
base on this link
An alternative in making soap without using lye is to use glycerin soap or melt&pour soap or transparent soap.
how does a glycerin soap made, because based on my research, glycerine soap is also created by using lye.
this is the part which I couldn'tnot answer to my thesis. Please help.
The only difficulty which can keep you from making glycerin soap - the purchase of ethanol. Requires quite a lot of alcohol, vodka and it does not fit. If alcohol is freely available in your country - you're in luck! Proceed to the production! This typically takes about 60% soap butters, 1-5% stearic acid, theremainder is an oil. Alcohol - 40-50% (I use 96% alcohol (called an antisepticsolution)). Sugars 25-30% by weight of oils. Glycerol to 15%.
You will need: 15% coconut oil 50% palm oil 15% olive oil 10% oil minlalnoe 10% avocado oil 5% SF (perezhir) alkaline NaOH and water on the calculator additionally 4% by weight of stearic acid oils 50% ethanol (by weight of oil) 15% glycerol (by weight of oil) Sugar 25% (by weight of oil) 10% water syrup (by weight of oil) Soap turns opaque but very enjoyable!
