How does the use of detergent help to clean soiled clothes?

उत्तर
Detergents are substances that help clean dirty clothes by breaking down and removing dirt, grease, and stains. They contain surfactants, which reduce the surface tension of water, allowing it to pass through clothes more easily. Surfactants feature a hydrophilic (water-attracting) head and a hydrophobic (water-repelling) tail, allowing them to surround and remove dirt and oil from fabric. This technique rinses the dirt away with water, resulting in cleaner clothes.
