Laundry detergents play a very important role in cleaning habits. Besides their efficiencies, their impacts on the environment determine their places on the market. Nowadays concentrated (ultra) detergents are popular. Decreased impact on the environment is a driving force behind the development of concentrated detergents. Concentrated formulas mean smaller containers, less water and more efficient transport in the environmental point of view. They are also good for the clothes' appearances, handle and the life of washing machines. Although the concentrated detergents are announced as consumer friendly, there are some questions on the consumers' minds. The consumers tend to accept more is more. The reason for them to use more detergent does not provide more soil releasing effects. The proper dosage is the key to get optimum results. In this study a comparison between two types of commercial detergents were made. One type was traditional and the other one was concentrated. The comparison was made by using standard stains and constant washing conditions except than wash temperatures and applying the recommendations for the amount of detergents to be used for the washing procedures.
