SURFACTANTS IN TEXTILE FINISHING PROCESSE S .15. USE OF CARBOHYDRATE-BASED SURFACTANTS AS ALTERNATIVES TO TRADITIONAL SURFACTANTS IN TEXTILE WASHING PROCESSES .1.

The physico-chemical properties such as foaming, static and dynamic su rface tension, and the solubilization behaviour towards Sudanred G of a C-12-C-14-Alkylpolyglucoside (APG) alone and in combination with a C -12-C-14-NaSO4 (FAS) was determined to check their applicability for t extile washing processes. Furthermore a C-16-C-18-Alkylglucoside emuls ifier was used as antifoaming agent to reduce the foaming of the very foam stable APG/FAS-mixture. The results were compared with those of a washing auxiliary based on a fatty alcohol ethoxylate (FAE). The APG reduced the static surface tension in the same manner as the commercia l FAE does, but at lower detergent concentrations. At 60 degrees C APG diffuses much faster to new formed surfaces than the textile washing auxiliary as was shown by dynamic surface tension determinations The s olubilization power of APG and the APG/FAS-mixture towards Sudanred G was also higher in comparison to the commercial FAE. The ratio of BSB5 /CSB was between 0.46 and 0.57 for APG, FAS and the antifoaming agent, whereas it was 0.18 for the commercial auxiliary.
