Cracked Soap: Cracking the Code

Have you ever wondered why most bars of soap crack after a few uses? Many people have opted to buy liquid soap because they don't like the look of unsightly cracks that absorb dirt. Many people also opt to have a bar of "display" soap that they don't use because it looks pretty until you use it.

Pineapple Home Apothecary soap does not crack. My soap is cold-process soap and it differs from the "triple-milled" or "French milled" soap that cracks after several uses or gets mushy on its underside.

Triple-milled soap is soap that is pushed three times through a milling machine three times to push glycerin into the soap and press water out of it. This produces a hard, long-lasting bar, but the caveat is that it cracks when it takes on moisture. These cracks develop quickly and cause the soap to look unsightly in a soap dish.

French-milled soap goes through the milling machine one time.

Cold-process soap does not go through a machine press. It is created by mixing sodium hydroxide (lye) with water and then oils, fragrance oils or essential oils, clays, mica, goat's milk, or in the cases of other companies, dyes or chemicals. Pineapple Home Apothecary soaps are all cold-process soaps that contain no dyes, synthetics or chemicals and become soap in 24 hours, and then cure for 6 weeks while the moisture evaporates to produce a harder, longer-lasting bar. The combination of oils is what makes my bars moisturizing and high in lather. The Castile soap cures for one year to produce an even harder bar.
