What kind of reaction occurs when making lye water?

Saponification is an exothermic chemical reaction—which means that it gives off heat—that occurs when fats or oils (fatty acids) come into contact with lye, a base.

Is lye soap toxic?

Lye is a caustic substance that can certainly damage your skin if you’re exposed to it. It can cause a number of problems, such as burns, blindness, and even death when consumed.

Why does lye react with water?

The liquid dissolves the lye and creates a lye solution. Mixing water and lye creates an exothermic reaction that causes a dramatic temperature increase. Adding lye to room temperature water can cause the water to reach temperatures up to 200 ° F. The mixture also creates fumes, which should not be inhaled.

What does lye react with?

Lye will react with metals such as aluminum, cast iron and steel. It should be stored and mixed in ceramic, stoneware, glass or heat-resistant plastic containers. Glass should be used with caution because it may break due to the heat released when lye reacts.
