【英文摘要】Through the conduction of a set of experiments based upon orthogonal design, an optimal formulation using layered sodium silicate STHS-1 as non-phosphate builder was developed.This new formulation has a better cost/performance ratio. Products made in accordance with this formulation were compared with some non-phosphate built laundry powder purchased from the market with respect to detergency and ash deposition performance. At the same time their cost/performance ration was carefully evaluated. The results show ...
