READ BELOW FOR USAGE
Lye (NaOH) commonly referred to as Lye or Caustic Soda is used in bar soap making and widely used as a pH buffer in cosmetics. 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.
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.
Glass including pyrex can shatter when mixing your lye water, use stainless steel or #2 and #5 code Polypropylene
When handling Sodium Hydroxide, always wear gloves! Lye burns. Sodium Hydroxide can cause nasty burns on your skin. In addition, you should only use Sodium Hydroxide when wearing eye protection, wearing a long-sleeved shirt, closed footwear and 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.
