Sodium Hydroxide - Pure - Food Grade (Caustic Soda, Lye) (2 Pound Jar)

If you’re diving into cold-process soap, this is your magic ingredient. This NaOH is high-purity, lab-grade clean, and perfect for soap, biodiesel production, cleaning prep, or even food uses (like pretzels—yep, seriously). But let’s focus on soap: I’ve used this exact jar to make multiple 1–2 lb loaf batches of cold process, and it’s consistent, easy to measure, and behaves beautifully in solution.The 2 lb jar gives you plenty of product for a good run of batches, and the crystal form dissolves cleanly—no clumps, no weird off-gassing if you mix it properly. Just respect it: always add lye to water, never the other way around. And ventilate—your face will thank you.

This lye worked well for my soap. It did take while for it to harden but that could’ve been due to certain oils I used. Great size and will last me a while. I recommend using safety equipment when working with any lye to avoid any irritation.

Great product! I use this for making soap. Fair price and always arrives in new condition. Works well in my soap products.

I've used this for soap making multiple times and have never had an issue.

Good deal and does the trick. I used this in some soap recently and it worked well. If you're knew to this, read instructions and use all safety protocols mentioned. It is dangerous, if you're careless.

Lye is notoriously caustic, but this particular batch need to have something added to it. Compared to previous batches of food grade lye, this product takes longer to heat up, doesn't get as hot, and doesn't foam as much. In fact, the fumes from using this to clean pots and pans smells rather sour. Maybe there is some sort of additive that retards the reaction with water. I was intending to use this for soap, but will probably consult a commercial supplier. It's still fine for cleaning and pretzel blanching, though.

Mix with water, great for baking pretzels and getting that dark color and pretzel flavor!Be safe handling it!!

I bought this for making soft pretzels. It works great. It gives them the unique taste and that dark golden brown color.I use 1/4 cup lye with 5 cups of boiling water. I pour the water into a glass dish then slowly add the lye. It boils up when you add it so go slow and be careful. I then put on a glove and add the formed pretzel dough letting it soak for 10-20 seconds. Take it out the letting it drain for a couple of seconds then onto some parchment paper.I noticed that they cook faster than when I used baking soda so keep a close watch on them. Mine cooked in 9 1/2 minutes versus 15 with baking soda.I wouldn’t make pretzels without the lye. It makes all the difference.
