Description
A general class of materials that, when dispersed in a liquid such as water, aid in the removal of dirt, oil, stains, and contaminants from a surface. Detergents contain a surface-active compound (surfactant) that has hydrophilic and hydrophobic groups, thus allowing the surfactant to contact a contaminant, then reduce its surface tension and wet it. The contaminant can then be displaced, solubilized, or emulsified. Synthetic detergents are generally classified as
In addition to surfactants, detergents may contain other additives such as bleaches, whitening agents and sudsing agents. Some detergents are designed to work in nonaqueous solutions such as gasoline and dry cleaning solvents. See also Cleanser and Soap.
