/diy/ - Do It Yourself

Nearly all soaps use sodium hydroxide (lye). If they don't, they really can't even be called soap, legally. But to answer your question: Not at all.

The reason is that when the soap is finished curing, there is NO lye left in the soap (provided you made it properly). Lye itself is very caustic and can cause severe burns, but when added to the oils in the proper proportions, the process of saponification changes everything chemically into soap. There's no lye left in the soap once it is finished curing. That is why, if you make cold process soap, you have to let the bars cure for 4-6 weeks. That ensures that everything is fully saponified.
