Potassium Hydroxide: Used for making Liquid Soap,  each container has 2 pounds by weight. Potassium Hydroxide, also known as potash, lye, or KOH, is the chemical that induces saponification with fats and oils to create that magnificant thing called liquid soap! Please be sure to educate yourself on the safety precautions and proper handling of Lye before using this ingredient.

Making Liquid soap is a little different than making bar soap. Check out our Online E-book 'Liquid Soapmaking' for everything you need to know to make liquid soap successfully. 

Storage: Potassium Hydroxide is extremely hygroscopic (attracts moisture) so be sure to always keep it in a sealed container in a cool dry place. If left out, it can attract enough moisture from the air to turn completely liquid!

NOTE: When you order this item you must agree to the Hazardous Materials Waiver. This item may only be shipped via Ground Only to the continental (48) United States.

Safety and Handling: Visit this post on the Soap Queen Blog for information on how to safely use Potassium Hydroxide.

KOH Purity %
Great product. It should however contain the KOH purity % in the product description, AND most importantly, on the bottle itself. I double checked my bottle, and it's not listed. Knowing this % IS important to know, especially when running recipes, and formulating recipes through a lye calculator. Again, this is a great product, but I'm docking it 1 star because of not listing the purity %... Come on Brambleberry. With as much as you push safety and running recipes through a lye calculator, this should really be a no brainer... Colin

First time using, mixed results
Mixed results and disappointed that BB doest offer even one free recipe for using this product. Heres a tip from BB (tip was given on the Castile soap concentrate product I for page) that would have been helpful to include in product description for making liquid soaps, "Special Tip: You can also use .5 oz. table salt (very important it be plain table salt, just the cheap stuff) dissolved in 1.5 oz. distilled (warm) water to naturally thicken the soap prior to adding fragrance. We use about 12 ml of the salt solution in 16 oz. to get a very thick soap. Give it a try!" Had this tip been included I wouldn't have wasted money buying liquid crothix which did absolutely nothing to thicken my Castile soap.

Hi AJ! I'm sorry you were unhappy with the description on this product. This Liquid Soapmaking Online Video has step-by-step instructions, an easy recipe and tips for making liquid soap. Making liquid soap is a very in-depth and multi-step process that isn’t easy to show in a blog post or regular length video, which is we provide this Liquid Soapmaking E-Book and created a full length video to help people learn to make liquid soap. I'll be emailing you personally to discuss this issue!

Lye description
The Lye description should contain the exact concentration of KOH in the container. It should also link to safety and mixing instructions.
