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.

Works great for soap making. It is a little harder to measure than crystals.

Not the best option for Milk Soap.
New soaper, but I've made hundreds of bars over the last two months. I only do CP goat milk soap. I love BB, and I'm not knocking the product, but it's not the best option for milk soap. I was using microbead lye from another supplier. I hated that the beads bounce and cling to my plastic measuring cup. However, the microbead form dissolves perfectly and quickly. I KNOW that it's dissolved, and that's really important in goat milk soaping because you can't see through milk. Because of the static and bounce issues with the beads, I gave the lye flakes a try. I'm sure they're great for other types of soap, but they take FOREVER to dissolve. After 30 mins of stirring and stirring, I still see bits in the bottom of the bowl when I pour it into my oils, after I was sure that I'd gotten them all broken and dissolved! I'd rather have the worry of a bouncing bead than the worry of lye chunks in my finished soap. Really frustrated and worried about the last two batches I've done. :( Argh!

Hi Kristi! I'm sorry this product wasn't your favorite. We like using the flakes because they're easy to measure and there is less chance of them poofing up in the air when you measure it out. In our tests and recipes, we've found it dissolves fully. However, because the milk is typically frozen when you're adding the lye, it can take a little longer to incorporate it, as seen in this Goat Milk Soap Tutorial. I'll be emailing you personally to talk about this!

I wasn't sure how much I would like this, but I LOVE it. The lye is in flakes that are very easy to measure, quick to dissolve, and the lid is like that of a pill bottle so it makes it difficult for children to open. The bottle is nice and big making it easy for me to grip and there is a very clear label on it to make sure that no one grabs it looking for the wrong thing. Although I do keep my soaping supplies & tools separate from the kitchen.

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.
