Studies on Removal of a Fatty Soil Mixture of Triglyceride and Fatty Acid

Effect of the presence of fatty acid soil on removal of triglyceride soil from cotton fabrics in an alkaline builder solution was studied. Cotton fabrics were soiled with a mixture of triolein and individual fatty acids such as lauric, myristic, palmitic, stearic, and oleic acid. Triolein and individual fatty acids adhering to cotton fabrics were determined by gas-liquid chromatography (GLC) after the extraction with ethyl ether. Triolein alone was hardly removed by a sodium carbonate (Na2CO3) solution, however, when triolein was mixed with individual fatty acids, its efficiency of the removal increased in the order C12
