Sažetak
Investigations of washing agents are interesting from the technological and environmental points of view. The trend towards natural ingredients is growing and vegetable- derived surfactants are gaining popularity in “green formulations”. Soap nut tree, Sapindus mukorossi, is a source of natural surfactants, saponins. Soap nut shells as an alternative washing agent to commercial detergent, are studied. Washing performance of tested agents is studied at different temperatures, 60 and 90 °C. Primary washing effect of soap nuts and detergents is obtained applying naturally soiled cotton fabrics. Spectral characteristics of washed samples compared to unwashed indicate beneficial primary effect of washing with soap nuts, especially at 90 °C. Secondary effects are evaluated using a reference cotton fabric washed through 10 cycles in a washing machine. The obtained effects are studied after 1, 3 and 10 cycles applying the following control criteria: ash content, chemical wear, decrease in breaking strength and whiteness quality of washed samples compared to unwashed. Better multiple washing performances of the natural saponins are confirmed through less ash content as well as low level of chemical and mechanical damage. The whiteness degree of multiple washed cotton fabrics with saponins is not increased, as there are bleaches or fluorescent components in soap nut shell. Nevertheless, washing with soap nut shell provides many benefits to consumers.
