CLASSIF OF CLEANING AGENTS

• • Surfactants, or surface-active ingredients, are chemical agents that aid in cleaning surfaces that contain oil, stains, and dirt, which usually are not soluble in water. They include a hydrophilic (water- loving) polar head and a hydrophobic (water-fearing) nonpolar tail. The head interacts with polar molecules like water, while the tail that is usually comprised of a hydrocarbon chain attaches to nonpolar substances like oil.
• • Bleaching agents are formulations that cause whitening – or lightening – to an affected substrate by solubilizing color-producing substances or by altering their light-absorbing properties. These substances are usually oxidizing agents, such as peroxides and chlorine.

  .
• • Disinfectants are substances made to lessen, if not eradicate, harmful microbes on surfaces.

  Sanitizers work in the same manner as disinfectants
