Sodium Hydroxide, also known as Lye, is what allows the necessary chemical reaction to take place during the soap making process. Our lye is 99% pure and is in bead form. We package it in a resealable HDPE canister which should be stored in a dry place (It is important to keep Lye away from moisture when storing). There are 2 lbs of Lye per canister with a maximum of 12 canisters per order. There is no need to fear working with Lye when it is worked with safely. It only becomes caustic when combined with water, so please take the necessary safety measures for handling and storing. By taking appropriate precautions, you can safely enjoy making “true soap” with lye. Please read and familiarize yourself with the necessary safety precautions found here. You can also review a Material Safety Data Sheet for Sodium Hydroxide (Lye, NaOH) for more safety and product information. *We only ship Sodium Hydroxide by FedEx Ground. Those with orders that choose expedited shipping and contain Lye risk delaying their order. *Due to shipping requirements, we cannot accept returns of Sodium Hydroxide (Lye, NaOH). All sales are final.
