Often in the summertime, when you receive your soaps during humid conditions, you may notice some of the soaps and wrappers may have some wet spots. It looks like almost "sweat" coming out of the soaps. There is absolutely nothing wrong with the products. Actually, it's a good thing and here's why.
Quality handcrafted soap bars often "sweat" in humid weather due to the high content of natural glycerin. Glycerin is a byproduct of saponification, the chemical reaction between oils and lye that produces soap. Glycerin is a humectant which attracts moisture from its surroundings. When handmade soap sits out in humid conditions, the glycerin in the soap will attract the moisture in the air and keep it on the soap. That's the "sweat" you see.
Handmade soaps are rich in natural glycerin and act like a moisturizer every time you wash with them. It leaves a thin layer of natural glycerin on your skin and naturally retains the moisture in the skin. In commercial soaps, on the other hand, the glycerin is removed and used to produce other products like moisturizers, lotions and cosmetics. That's why commercial soaps are drying to the skin. If you tend to have a dry skin condition, it would be best to stay away from commercial soap/body wash and choose a soap made with natural ingredients.
All of our soaps and shampoo bars are made with other natural humectants – or moisturizing ingredients – such as sea salt, unpasteurized honey, and castor seed oil. That's why they quite often sweat, especially in the summertime when humid.
In our studio, soaps are kept as dry as possible during the four-week curing stage and make sure they are not "sweating" when we ship them out to you. However, during the transportation in the humid weather, or after you receive the products, they may develop some natural sweating. And that's completely normal and a sign of quality natural soaps. To prevent the soaps from sweating further, please keep them in a cool dry place away from direct sunshine.
