If you search Google for "soap definition" it gives you this: "a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide or another strong alkali, and typically having perfume and coloring added."
The FDA provides a similar definition. My question is: What is "another strong alkali" that can be used to make soap?
Thanks.
