INTERFACIAL-TENSION AND WETTING - PARAMET ERS FOR PRODUCT CHARACTERIZATION

The performance of a product constitutes of different part-processes. In most cases these can be described and quantified by physico-chemica l effects. Exemplary parameters are the interfacial tension between th e oil- and the aqueous phase as well as the wetting of solids They are discussed with respect to their importance for practical applications The possibilities To characterize products by physico-chemical parame ters are demonstrated following the examples of detergents dish washin g agents and all-purpose cleaners
