A single enzyme will typically catalyse around 10, chemical reactions per second. This means that only a tiny amount of enzyme is needed to have a huge effect on a reaction. The rate of enzyme activity depends on the amount of enzyme present, and also the temperature and pH of the reaction solution. The most favourable pH for many enzymes is , around neutral, but there are exceptions: pepsin, a digestive enzyme in the stomach, works best at pH 2.
People have been experimenting with ways to use the power of enzymes to clean clothing for a long time; in fact, the first patent was in Because stains are made of different types of molecules, a range of enzymes are needed to break them down. Proteases break down proteins, so are good for blood, egg, gravy, and other protein stains.
Amylases break down starches, and lipases break down fats and grease. Washing powders usually only contain one type of enzyme, though some have two or all three.

The proteins "eat" odor and stain-causing bacteria, a feat normally accomplished with synthetic, chemical cleansers.
These catalytic proteins are featured in a number of laundry detergents, their inclusion designed to make cleaning easier and more environmentally friendly. Arm and Hammer's website advertises two laundry detergent products that contain enzymes. Both of these detergents are available in their Power Gel line of cleansers. The manufacturers claim these products contain multiple enzymes for added stain removal power. The Material Safety Data Sheet for the Arm and Hammer Plus OxiClean detergent states that the product contains zero to 2 percent enzyme mixture based on the weight of the product.
The MSDS for Arm and Hammer Powdered laundry detergents, including the phosphate, nonphosphate, fragrance free, color-safe bleach and fabric softener versions, lists the product as containing less than 1 percent of a protease enzyme preparation.
This stuff forms the film that holds the other ingredients in a jolly, candylike form. It's a water-soluble polymer related to Elmer's Glue: Pop it in the wash and it dissolves, releasing detergenty goodness without any messy spills.
Tide has said its three-chambered design "maximizes the consumer experience," which probably means keeping the ingredients separated so that they don't neutralize each other while sitting on the shelf. In , Tide added a bittering agent to its outer film to discourage kids from eating and swallowing it.
Their additive of choice: an inert, white powder called denatorium benzoate. You may know it as soap. It works by attaching its hydrocarbon chain to the grease or oil in a clothing stain, allowing both to be washed away by water. This could be any of several linear anionic surface acting agents.
