Q: Why is lye needed for soap?
A: It is required to convert oils into soap through saponification.

Q: Can true soap be made without lye?
A: No. True soap made from oils and fats requires an alkali such as sodium hydroxide.

Q: Is finished soap harsh because it uses lye?
A: When formulated correctly and fully cured, the lye is consumed during saponification and the finished soap should be suitable for normal use.
