Worked Well for My Electrolysis Demonstration
This potassium hydroxide product worked well to demonstrate the decomposition of water into hydrogen and oxygen gas through electrolysis. Anyone handling chemicals like this should know to always add this product to the water and not the reverse because the possibility of "flashing" the solution explosively. If I need any more in the future, I would not hesitate to buy this product again.

Used In Hydrogen Welder, Great Product
Bought as the reactor for our hydrogen water welder, great price seems like a bottle will last about 8-10 full tank cycles (we use our water welder 24/7 in a wax mfg house). High quality, I recommend

Still a good buy
This year works very well for cp soap. I did however receive 1 bottle that ruined every batch made with it. It was a different texture than previously received and 6 batches of soap later 😬

This is a must when making liquid soap paste
I always use this to make my soap paste that I use in making liquid soap. I have always used this brand ever since I started making liquid soap many years ago. It is the best price, the quality is great and I trust the company. I believe it is the purest grade you can find. It is food grade which means it has the lowest parts per million of heavy metal impurities in it. Being made in the U.S. is what I look for also.

Perfect for soap making
High quality and worked out fine in my liquid soap! I did not get my first order on time (it got lost in the void between UPS and the post office "smartpost" isn't so smart) and wrote in to them and they immediately sent me out another, free of charge and via a more expensive shipping method that takes USPS out of the equation, and told me that if the first one surfaced to go ahead and keep it. I did eventually receive the second one and I have no idea if I'll be able to even make enough liquid soap in my lifetime to use up all this lye but between a high quality product and high quality customer service (as well as really fast shipping turnaround time if you take smartpost out of the mix) I couldn't be happier. I wish there were another star to give. Top notch here.

Great for CP soap making
I was previously trying a different brand but the shipping was slower and the price was crazy and I had to pay for shipping. This checked off all the boxes and soaped perfectly

Good and fast service

Excellent potassium hydroxide for soap making. Safely packed in sturdy, thick plastic container. It has child-proof cap and not easy to be opened. As per the MSDS available online, the purity is around 90%.
