Powdered soap is a washing product that combines cleaning and protecting functions, offering the advantages of being naturally gentle, strong in cleaning power, and producing less foam for easy rinsing. Its active ingredients are mainly fatty acids, with over 90% of the raw materials coming from renewable plant oils, and it does not contain polyphosphates. It comes in a variety of specifications, with common small packages ranging from 200-500g, convenient for travel or short-term trials; household sizes are mostly 1-3kg, such as the 2.3kg Da Canal Natural Powdered Soap, which can meet daily laundry needs; large packages are available in 5kg or more, suitable for commercial scenarios like restaurants.
