Why is it possible to make soap with olive oil?
Olive oil contains several fatty acids (oleic, linoleic, palmitic, stearic…). Caustic soda (NaOH) itself is a strong base.When an acid joins a base, a chemical reaction occurs that produces salt + water, which is usually exothermic (gives off heat).
The most common soap to make is caustic soda, but you can also use caustic potash (KOH) to make liquid soap or detergent if you prefer.
If you want to produce soap without the use of caustic soda, caustic potash is an alternative, although it is more aggressive than caustic soda, so you must be very careful when handling it. The end result is also different.
The reaction that occurs when oil is mixed with a strong base is called saponification.
During the saponification process, fatty acids combine with fatty acids in water to form soap and glycerin.
What do you have to prepare before making soap with olive oil?
Before making soda soap, you should prepare protective gear and prepare the necessary ingredients for soap making.
To safely make homemade soap, you should consider the handling practices recommended by the supplier of caustic soda.
The most common is to use waterproof gloves and goggles. Although we also recommend that you cover both to protect your nose and mouth. For this you can use a mask.
• Waterproof gloves
• Safety glasses
• Face mask
• Plastic container (9 liters)
• Stick or tool to remove
• Soap molds

You can add drops of essential oils or fragrances, such as lavender, thyme, rosemary, sweet almond, coconut, shea butter, aloe, and more. Or garnish it with herbs or fruits to make them fragrant.
Steps to follow to make soap with olive oil
Next, you will see how to make a spectacular homemade soap from used oil.
First of all, keep in mind compliance with the security measures that we have previously mentioned. This is probably the most important point.
Pour 3 liters of water into a plastic bucket.
Very carefully, add 1 kilo of caustic soda to the water, stirring constantly until it dissolves completely (when the mixture looks transparent).
Stir slowly and carefully with the stick or tool of your choice.
This results in an exothermic reaction that releases heat and raises the temperature of the mixture. At this point, you must be very careful as any stain can cause skin burns.
After about 5 minutes, the water and baking soda mixture becomes hot. Then add little by little 5 liters of used oil. Keep mixing in the same direction and try not to splatter.
It is important to note that you filter the recycled oil until you are sure that it does not contain impurities.
Now all that’s left is stirring. You should do this for 1 hour until the mixture resembles mashed potatoes. Don’t worry about clumping, the soap will be smooth when completely dry.
Pour the contents of the block into the tray or mold of your choice. At this point, you just have to wait about 10 days for the soap to be ready to break the mold and cut. After cutting, it is recommended that it dry for an additional 10 days before use for satisfactory curing.
