Why are there two different “recipes” for a self-made disinfecting solution?

Disinfection usually requires soaking or drenching the item for several minutes to give the chemical time to kill the remaining germs. §746.3411 (1)(A) lists a weaker self-made disinfecting solution (One tablespoon of regular strength liquid household bleach to each gallon of water) to be used on those items which children routinely place in their mouth.
