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.

Answer 1

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!
