If you make your own the one thing to be sure of is the oil has to be essential oil, the kind that is okay to put in soap. It's kinda pricey but will last a long time. My recipe says a few drops of the essential oil. I have used the recipe since I was in my teens. We made it in Home Ec. class by the gallon for refills. The teacher bought in Vodka and no one thought to sue. LOL I was so glad when I discovered Best Press and Bounce. No more having to make it.
