Why do handmade soaps go “gluggy”, or seem to melt before my eyes?
Most handmade soaps are made using the cold process method, which retains the naturally formed glycerin in the final soap bars. Glycerin attracts moisture from the atmosphere, and this makes the soap very soft, if the soap isn’t able to dry out between use. Provided handmade soap is stored on an open rack to allow it to dry out between use, it will significantly outlast mass produced soaps containing very little glycerin.
