摘要
Abstract
The properties of lignosulfonates (LSs)and its potential application as detergent builder were investigated. The mechanism and performance of sodium lignosulfonate (LS)as well as its modified product (GLS)in detergent formulations were discussed. The results showed that GLS exhibits better emulsifying power,foaming power and lime soap dispersing power than that of LS. After decolorization,the whiteness retention value of decolorized LS (LSW)on white swatches achieves 91. 93%,while that of decolorized GLS (GLSW)achieves 99. 37% . It demonstrated that the decolorizing process could solve the staining problem on white cloth and eliminate the negative effect of LS appears in the laundry process. Blending of LS or its modified product in the laundry detergent exhibits enhanced detergency for sebum soil removal. These results suggested that LS and its modified product may provide a new perspective as a builder for formulation of laundry detergents.关键词
