A detergent is a surfactant, which exhibits cleaning properties in water. Detergents are also referred as alkylbenzenesulfonates, a class of compounds that are quite similar to soaps. These compounds have molecular structure, properties and cleaning action similar to that of soaps. These compounds are amphiphilic- partly hydrophobic or non-polar and partly hydrophilic or polar. This allows them to remove oil, dirt and grease. Further, these compounds are less affected by hard water containing magnesium and calcium ions. These cleaning agents are commonly available in the form of powders and concentrated solutions. These compounds can be classified as laundry detergent and dish detergent. http://amplify.com/u/a1edjr
