Powder detergents are cleaning agents in a powdered form, commonly used for laundry. They contain surfactants, enzymes, and other ingredients that help remove dirt and stains from fabrics. Powder detergents are often effective in hard water and can be more cost-efficient than liquid alternatives. These detergents are typically packaged in boxes or bags and can be measured easily for different loads of laundry. They dissolve in water during the wash cycle, releasing their cleaning agents. Many brands offer specific formulations for various washing machines, including high-efficiency (HE) models, to enhance cleaning performance.
