Giuseppe De Giacomo,Maurizio Lenzerini,Francesco Leotta,Massimo Mecellaidentify product equivalents and surfactant suppliers. Application information, where available, is usually scant or given as a footnote. This new directory approaches the identification of surfactants primarily from the applications standpoint. Hence the formulator or end-user can readily assess th

When properly designed, they can be as much as three orders of magnitude mor
