Here's why:

* Cleaning Power: Laundry detergents need to break down dirt and grime, which are often acidic. Bases are good at neutralizing acids.

* Surfactants: Laundry liquids contain surfactants, which are chemicals that help remove dirt and grease. Many surfactants are alkaline.

* pH Levels: The pH of laundry liquids is typically between 8 and 11, indicating an alkaline solution.

However, there are exceptions. Some laundry liquids are formulated with specific ingredients that might make them slightly acidic.

It's always best to check the product label for specific pH information if you have concerns.
