Surfactant vs. Detergent: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
A surfactant is a substance that reduces surface tension between liquids and solids, while a detergent is a cleaning agent, often containing surfactants, used to remove dirt and grease.
Key Differences
Surfactants are chemical agents that alter surface tension between different substances, like oil and water. Detergents, on the other hand, are cleaning products that use surfactants to break down and remove dirt and grease.
