Surfactants are the main cleaning agents in most cleaning products. They can be made from natural sources or synthetic sources. Natural surfactants are made out of vegetable or animal fats. Synthetic surfactants are made out of petrochemicals. The molecules in surfactants attract to dirt and oils. They release their bond to the dirtied material. Different surfactants attract to and release different forms of dirt and oils.
Enzymes are protein molecules. When added to cleaning products, they increase the speed of stain removal. The enzymes attack and break down dirt and oils. There are different types of enzymes, each effective on different types of stains. Cleaning and stain fighting product makers choose enzymes to include in their product formulations, based on the stains they want their products to remove. Shout must formulate its products to include ingredients that are harmless to the enzymes. Bleach would destroy the enzyme molecules, making them ineffective.
