Questions about cold process handmade soap and saponification reaction

It sinks to the bottom of the water

Because the normal temperature reaction process of cold soap lengthens the saponification time, the resulting mixture of sodium fatty acid, glycerol and non-saponifiable substances mixed with water after complete reaction is The specific gravity is greater than water, so it will sink to the bottom of the water.

There is a large error between the theoretical reaction degree of cold soap and the actual reaction degree

To judge that the saponification reaction is complete, the T state is the end state of the cold soap reaction
