Sodium Hydroxide: LYE - for Soap Making. Sodium Hydroxide, or Lye, is the chemical that induces saponification with fats and oils to create that magnificent thing called soap! Our lye is now in flake form! This is a huge improvement because they don't cling to you and your tools due to static electricity like the pellets do. The flakes are a little less pure (97% instead of 99%) but this small variation does not make a difference in soap recipes and saponification rates.Please be sure to educate yourself on the safety precautions and proper handling of Lye before using this ingredient. Our Lye is 32 oz. by volume and 27 oz. by weight.

How do you use this type of law in soap?
I'm a M&P soap maker and I want to start making cold process soap. I'm used to seeing it as a liquid not in a flake form. How do you make cold process soap with this form of lye?

Hi Destiny! To use this product, measure out how much lye you need. In a separate heat-resistant glass container, measure out how much distilled water you need. If you need to find out how much lye to add to your recipe, check out our Lye Calculator. Then, slowly add the lye to the water and stir until all the flakes are dissolved. You can see the process in this How to Make Cold Process Soap: Lye Safety and Ingredients video. I'll be emailing you personally to help out!

Great Product
I am new to soap making. I have never made any soap until last night. I started reading all the material I could find then I ordered what I needed. I followed all the directions for using the lye and my soap turned out great! I was scared to use lye because of the warnings I had read but the large flakes of this product made for easy handling and I was amazed about how well it mixed. My soap turned out great and I can't wait until the soap cures so I can use it. Remember I am new to everything and this was my very first time and all turned out great.

Scared Lye Virgin!
I used lye for the very first time today as I ventured into cold process soap making. Like most people, my biggest fear was mixing that lye. I was so relieved to find these LARGE flakes of lye. They poured out great, didn't go anywhere but where I put them. Will definitely stick with this and not venture further. I feel very confident using this lye. Thank you sooo much for offering this flake form. I must say that the flakes surprised me by their size. I thought they were much smaller. Love them! Also, the bottle came inside a plastic bag and arrived in perfect condition.

To try it
Been purchasing fragrances from BB, the lye I've used is been 100% from hardware store in pearl form. It did jump when carefully spooning out. Right now I have stopped making soap because I've developed an intoxication from chemicals, love making soap and can't wait to try this lye form after I get better. For the record I did use a surgical mask and gloves when soap making.

I really like the flakes! Easy to pour, but I have a question: for the 33 oz. soap batches, the lye calculator says to use 4.6 oz of lye, but is that in weight or volume? I've been doing weight, and it always turns out great, but just realized that and wanted to ask. I'll keep using this lye for my cp soap!
