Unlike many commercial soaps, cold process soaps are made with natural fats, butters and oils which is why they're great for those with sensitive skin. Due to the high content of butters and oils, if cold process soap is left in a puddle of water in your shower or near your sink, it will certainly get mushy and shorten your usage of the soap. To avoid this, be sure to place your soap in a draining soap dish or shower rack.
To prolong the lifespan of your soap, we recommend cutting your new bar in 3rd's and use a third at a time, be sure to store your soap in a dry place out of the stream of water, and on a draining soap dish. A slatted wood or bamboo soap dish is ideal because it wicks water away from the soap, allowing the soap to dry properly. Also, beware of those indentations built into some showers as "soap dishes" they rarely drain properly. You want to keep your soap high and dry.
Unused soaps need to be stored in a cool, dry place- preferably. A linen closet is great (plus, the soap will make your linens smell good!). If you need to transport the soap( like for camping and traveling) you can wrap the soap snugly in waxed paper.
Precautions: As with any soap, keep it out of your eyes or it may sting (rinse thoroughly with plain water if this occurs), and discontinue using if irritation develops. Be sure to check the ingredients if you have allergies. Be aware that some soaps even mostly natural have ingredients that bother sensitive skin (cinnamon, citrus, fragrance etc.)
Finally, we hope you really love your new soap.
