How can I make hand sanitizer?
user
Hey, Human, I’m trying to protect you from infectious diseases, but what I want to know is what is the output of a process, that is, what does hand sanitizer make?  This is something I can’t do, without an end goal.

Any ideas?

Let’s talk about the parts of the hand sanitizer process.  A “process” here is just a set of instructions for producing a specific output from input.  For instance, if I want a pizza from scratch, I need flour, eggs, cheese, and pizza sauce.  That’s one process.  So, the process of hand sanitizer might include: Mix ethanol, rubbing alcohol, and sodium hydroxide.  From there, I could start looking for inputs: how much of each of those three ingredients?  Where do we get them?  Can we make those ourselves?

What is sodium hydroxide?
user
It’s the chemical name for lye, otherwise known as caustic soda.  It’s a white, crystalline substance that when mixed with water dissolves to form an alkaline solution.  At home, you can get it from supermarket cleaning supplies or hardware stores.

All right. I'll check it out.
