What are detergents used for in laundry?

Detergents play a crucial role in the laundry process primarily by removing dirt, stains, and oils from fabrics. They are specially formulated chemical agents that contain surfactants, which help to break down and lift away these unwanted substances from clothing. When you add detergent to the washing machine, it interacts with water and effectively encases dirt and grease, allowing it to be washed away. This property of detergents makes them essential for achieving clean laundry and maintaining the appearance of fabrics.

While options such as softening clothes, increasing water temperature, and adding fragrance can enhance the laundry experience or provide secondary benefits, they do not represent the primary function of detergents. The main purpose remains the effective cleaning of fabrics, highlighting why the choice centered on removing dirt, stains, and oils is the correct answer.
