Soap vs. Detergent: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 21, 2023
Soap is a natural cleansing agent made from fats and lye; detergent is a synthetic cleaning product designed for specific conditions.

Key Differences

Soap and detergent, though both serve as cleaning agents, have distinct differences in their composition and applications. Soap is typically created by combining fats or oils with an alkali, such as lye. Detergent, conversely, consists of synthetic or man-made compounds.
