Handmade soap is made without synthetic preservatives or
artificial hardeners. One of the great things about handmade soap is that
it does not need these things added to them. If made and stored properly your
handmade soap will be very hard and long lasting.
The number one rule for prolonging the life of your soap is to
make sure it does not sit in a pool of water between uses. Get a good soap dish
that allows the water to completely drain away from the soap. The best type of
soap dish will also allow air to circulate around the bar. It is even better if
you can let your soap completely dry between uses. For soap that is unused
store it in a dark cool place like a lingerie
drawer or linen closet.
