Abstract

The most fundamental request for laundry detergents is the efficiency of washing. As widely accepted, the efficiency is affected by many conditions such as a wide variety of soils and stains, type of fabric, extent of mechanical agitation, cloth/wash-liquor ratio and so on. Therefore, many laundry detergent manufactures have been trying to improve the performance of detergents including the development in the evaluation methods of detergency. Recently, as the washing circumstance has changed, the various performances have been requested for the detergents by the consumers. In this paper, I describe the general evaluation method of washing performance and new functions of recent detergents.
