READ BELOW FOR USAGE INSTRUCTIONS

Lye (kOH) used in liquid soap making. Some soapers use both sodium and potassium hydroxide.  Dual-lye recipes are often used for specialty soaps such as cream soap, shave soap, and liquid soap.

90% purity, flakes

When working with lye never use vinegar on your skin! Water is best to rinse the skin area. It is fine on counters to neutralize.

Vinegar can neutralize lye, but it’s an exothermic reaction which means it heats up, which can cause additional burns on top of the lye burns.

Glass including pyrex can shatter when mixing your lye water, use stainless steel or #2 and #5 code Polypropylene

INCI: Potassium Hydroxide

Product No:  16155064

When handling Potassium Hydroxide, always wear gloves, goggles, closed footwear, long sleeve pants and shirts! Lye can burn you!  Use it in a properly ventilated area. Always keep your container tightly closed when not in use. Not only does air reduce its efficacy, but it will also attract moisture from the air and get chunky and hard to use.
