detergent

 [de-ter´jent]
1. purifying or cleansing.
2. an agent that purifies or cleanses.
3. in biochemistry, any of a class of agents structurally consisting of a nonpolar hydrocarbon chain and a hydrophilic polar head group, which reduce the surface tension of water, emulsify, and aid in solubilization of soil.

de·ter·gent

(dē-tĕr'jent),
1. Cleansing.
2. A cleansing or purging agent, usually salts of long-chain aliphatic bases or acids (for example, quaternary ammonium or sulfonic acid compounds) that, through a surface action that depends on their possessing both hydrophilic and hydrophobic properties, exert cleansing (oil-dissolving) and antibacterial effects; acridine derivatives (for example, acriflavine, proflavine) as well as other dyes (for example, brilliant green, crystal violet) have detergent properties for the same reasons.
Synonym(s): detersive

detergent

a substance that when dissolved in water acts as a cleansing agent for the removal of grease by altering the interfacial tension of water with other liquids or solids. Powerful detergents are used to break up oil spillages at sea.
