Soap, by definition, is fat or oil mixed with an alkali. The oil is from an animal or plant, while the alkali is a chemical called lye. In bar soapmaking, the lye is sodium hydroxide. Liquid soap requires potassium hydroxide.

When oil and lye are combined and heated, the result is soap. This chemical reaction is called saponification. Without lye, saponification isn’t possible, so lye is necessary to create soap

Answer:

Ingredients and equipment

coconut oil ⅔ cup (helps to produce lather)  

olive oil ⅔ cup  

other liquid oil ⅔ cup – like almond oil, grapeseed, sunflower or safflower oil  

¼ cup lye – also called 100% sodium hydroxide  

¾ cup cool water (use distilled or purified)

Quart canning jar

Pint canning jar

Soap molds

Gloves and protective goggles

Explanation:Instructions

Step 1: Cover your work area. Put your gloves and other protective wear on. Measure your water into the quart canning jar. Have a spoon ready. Measure your lye, making sure you have exactly ¼ cup. Slowly pour the lye into the water (never the water into lye) stirring as you go. Stand back while you stir to avoid the fumes. When the water starts to clear, you can allow it to sit while you move to the next step. It will generate heat as the chemical reaction occurs.  

Step 2: In the pint jar, add your three oils together. They should just make a pint. Heat in a microwave for about a minute, or place the jar of oils in a pan of water to heat. Check the temperature of your oils – it should be about 120°F or so. Although you can use a soap-maker thermometer, a regular meat thermometer will also work. Your lye should have come down by then to about 120°F. Wait for both to cool somewhere between 95°F and 105°F. This is critical for soap making. Too low and it'll come together quickly, but be coarse and crumbly.

Step 3: When both the lye and oils are at the right temperature, pour the oils into a mixing bowl. Slowly add the lye, stirring until it's all mixed. Stir by hand for a full 5 minutes with any spoon or spatula that is heat-resistant. It's very important to get as much of the lye in contact with as much of the soap as possible. After about 5 minutes, you can keep stirring or you can use an immersion blender. The soap mixture will lighten in color and become thick. When it looks like vanilla pudding it's ready.
