Fats:
150 g (168 mL) of palm oil (we filter it on filter paper, coffee strainer) - [density 0.892 g / mL]
150 g (162 mL) of coconut oil [density 0.927 g / mL]
Sodium Hydroxide Solution (lye) - 35% w / w:
47.6g of sodium hydroxide, 96-99% pure
88.4g of water to dissolve sodium hydroxide
107g Ethanol 96 GL (should be 83.5g, but we put an excess of 28% because there are evaporation losses.)
88g of sugar
50g of water to dissolve sugar
54.7g (43.5 mL) of vegetable glycerine [density 1.26 g / mL]
True soap mass (fats + sodium hydroxide, water is not counted) was 347.6 g
If we multiply 347.6 by 2, we have the soap mass that we will produce. This is because our soap will have 50% true soap, and the rest will be solvents (water, ethanol, sugar and glycerin).
So we will have 695.2 g of product. From this total, we calculate the following percentages for solvents:
15% water
12% ethanol + (20-30% to prevent evaporation losses)
15% sucrose (sugar)
8% glycerin
You can modify small amounts in this preparation, for example we use the following proportion for this soap:
17.3% Water - 695.2 x 0.173 = 120g (part will be used to dissolve sodium hydroxide, part to dissolve sugar);
12% Ethanol - 695.2 x 0.12 = 83.5g (add 20 to 30% extra ethanol as this amount evaporates during manufacture);
Sucrose 12.3% - 695.2 x 0.127 = 88 g
8% glycerin - 695.2 x 0.08 = 55.6 (54.7 g it was used)
We used a slight excess of water (excess of 18.4 mL more than calculated) to ensure that all sugar dissolved.
