What temperature should lye water be?
What temperature should my lye solution be when I mix it into my oils? And how does the temperature of lye water affect the saponification process of the soap? can it be added too cool or too hot? Thanks
For instructions on soap making, visit my pages describing the Cold Process
and Room Temperature
Both use different lye temperatures and each works equally well.
The wrong temperature of the lye can have adverse effects. Too low and the soap may take forever to trace or could sieze quickly (this depends on the oils used in the recipe). To low temperatures can cause steaking and grainy textures. Too high of temperatures can also cause siezing and grainy textrures.
For cold process soap making, I like to use around 90 degrees and it works well for me. With the room temperature method, the lye is quite hot but because you are using it to melt the hard oils, I believe it cools down the lye to an acceptable level.
