Step 1
Surfactants
Answer
Surfactants play a crucial role in laundry detergents by reducing the surface tension of water. This reduction allows water to penetrate the fabric more easily, thereby facilitating the removal of dirt and stains. By allowing the water to better wet the fabric, surfactants ensure that dirt and grime are dislodged and dispersed in the wash water, enhancing the overall cleaning efficiency.
Step 2
Enzymes
Answer
Enzymes in fabric detergents are designed to target specific types of stains, particularly those derived from proteins, such as grass or blood. They work by breaking down these larger protein molecules into smaller particles, which can then be more easily removed during washing. This enzymatic action allows the detergent to perform more effectively, ensuring a deeper clean on difficult stains.
