The surfactants offer excellent solvency, low foam characteristics and broad compatibility with formulation additives. They also provide good thermal and chemical stability, are miscible in various organic liquids and are liquid at room temperature with little or no odor. The Tergitol L Series surfactants available in North America include four biodegradable grades: Tergitol L-61, L-62, L-64 and L-81. A fifth grade, TERGITOL L-101, does not comply with the European detergent regulation but is an efficient foam control agent in aqueous environments.
