The foam-y handsoaps (like Kandoo and Bath and Body Works) that kids love are basically made of watered-down soap. You can use regular soap refills and add water to them. I fill my soap pumps with 1/4- 1/3 soap, and then almost to the top with water, then shake it up. Works great! Don’t use any soap refill with microbeads in it, though – those will clog the dispenser.
