Laundry Detergent Ingredients and How They Work
May 07, 2021·Laundry detergents have come a long way since the first bar soaps made from animal fat and lye were offered for sale in the 1700s. The introduction of synthetic detergents to the marketplace in the 1950s offered homemakers more options for fabric care. But it was the 1970s that brought the most significant innovation in the laundry, the addition of enzymes that "attack" specific types of stains.

Soap is alkaline, which irritates sensitive skin, which is normally acidic. Alkaline skin degrades quickly as protease enzymes are activated that destroy the skin proteins. Soap forms scum when used with hard water (water that contains a high amount of calcium in solution). The scum stops the surfactant properties, so one tends to use more soap.
