The aim of the study presented in the paper was to demonstrate that using a combination of glycerin and surfactants in the form of sodium salts in the production of laundry liquid detergents might be an alternative to the currently commonly produced products based on surfactants in the form of potassium or triethanol ammonium salts. Tests were performed to determine functional standard properties of model liquid laundry detergent formulations with different contents of glycerin. The analysis focused on foaming power, rheological properties, solubility, washing ability and decrease in fabric strength after washing. The most beneficial functional properties, comparable to those found in formulations containing potassium or triethanol ammonium salts, were achieved at the glycerin content of 20%.
