Human: How to make a soap? Assistant: 
To make a soap, you will need the following ingredients: water, lye (sodium hydroxide), fats and oils (such as coconut oil or olive oil), an emulsifier like glycerin, and a preservative such as sodium benzoate. Begin by heating the water until it is hot but not boiling. Then, add the lye to the water and stir continuously until all of the lye has dissolved. Once the lye solution has cooled down, combine the fat/oil with the lye solution in a blender or food processor. Add the emulsifier and preservative and mix thoroughly. Finally, pour the mixture into molds and let it sit for 24 hours before removing it from the mold.
