Sodium Hydroxide Lye
Qty Price  
(max 5)


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.

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!

Lucky I was outside.
Normally, I always pour or scoop my lye in my soap room. However, upon opening my package and pulling out my lye I noticed that the little plastic baggie was covered and a fine dust. I couldn't figure out how it was covered. Upon even closer inspection I saw that the top was slightly open on the lye bottle. I assume this was just a problem during shipping. I went outside and started to open the bottle and a hazardous cloud of dust went everywhere choking me. I'm so scared to use it now and it was my only bottle. :(

Hi Jamie! Our lye bottles have an extremely tight seal, and are placed in a plastic bag in case the bottle is damaged in shipment. It sounds like the bottle was damaged slightly during shipping, which caused the plastic bag to come into contact with the lye. I will be emailing you personally to help you with this! I recommend opening bottles of lye in a well ventilated area, and some soapers like to wear a surgical face mask to prevent breathing in any dust. While lye is something to take seriously, with the right precautions it is perfectly safe to use!

I was told by several people not to use the flakes as they were harder to weigh and dissolve while making cp soap, but I ignored them and ordered this anyway! I'm so happy I did, I've had no issues with my soap, it dissolves very quickly, and the flakes are very easy to keep track of (if you spill a bit) since they are a tad larger. They don't hold that evil static cling, so you don't have to worry about some attaching to your sleeve while you aren't looking. Overall a wonderful product!
