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.

Product is fine, but the numbers are misleading
It works fine, though it's a little trickier to measure this out than the beads, but nothing that will prevent you from using it. One issue though: It says in the description "Our Lye is 32 oz. by volume and 27 oz. by weight." An ounce simply isn't a measure of volume, it is strictly a measure of weight. So to say that this is 2 lb of lye isn't true. It's only about 1.69 lb of lye (excluding the fact that it is only 97% pure, which would make it even less.) So the description shouldn't say "Sodium Hydroxide Lye, 2 lbs" because it isn't. It should say either 1.69 lb, 767g, or 32 fl. oz. If it's supposed to be understood that by 'oz' you mean 'fluid oz', then that's still a little odd: in any case, using a volumetric measure is misleading with small amounts of substance that are not liquids, such as this. I can't see a reason why any of us would be buying lye by volume. Anyway, the stuff works. But the numbers on this page are odd and/or wrong.

Hi Korgan! I'm sorry for any confusion! We've tried to clarify exactly what you get in the description. The jar is a 32 oz. jar, but in our sampling we found that how much you get by weight varies. It seems that it settles (kind of like cereal!) so the least amount you will get is 27 oz. but sometimes there is a little more. I'll be emailing you personally to discuss this!

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!
