Sodium hydroxide (lye) is essential in the process of making soap. There is no real bar of soap out there that has been made without lye. With that said, although lye is used in the process of soap making, there is no lye remaining in properly made soaps. This is because the chemical reaction of creating soap, called saponification, produces completely different molecules. The lye and lipid mix together to formulate soap and glycerin as the end product.
The shelf life of each soap bar is 1 year after purchase. Since HEDIYEH only uses essential oils as fragrance, it is best to use scented soaps within 3 months of purchase.
Superfat is a method used in soapmaking which leaves an amount of leftover oil molecules that have not reacted with lye. HEDIYEH uses this method in all of our soaps, which gives our soap bars more moisturizing and emollient properties making it gentler on your skin.
