Detergents and Cleaning Products

A detergent is a chemical compound that removes "soil". The term "SOIL" refers to any stain or dirt that has to be removed. Chemical cleaning compounds are based on detergent concentrates produced through a process called sulphonation and are referred to as sulphonates. These are the primary ingredients used in detergents and cleaners.
