Cleansing Power: How Does Dishwashing Liquid Work?
Have you ever wondered why it takes more than just water to get your clothes and dishes clean? Detergent dissolves in water and attaches to things like dirt and whatever is staining your clothes to help dissolve them into the water to be washed away. But how does dishwashing liquid work, and where does its cleansing power come from?
Most detergents are amphiphilic, which means they are partly hydrophilic and partly hydrophobic. Hydrophilic means a molecule is polar, and thus is attracted to water. Hydrophobic describes to non-polar molecules that don’t like to mix with water.
