Calfax® 16L-35

Calfax® 16L-35 is an aqueous solution of sodium hexadecyl diphenyl oxide disulfonate, which has a clear light amber appearance and contains no halogenated solvents. It offers superior solubility and stability in electrolyte solutions such as brine, bleach, caustic and inorganic acids. The long, linear side chain promotes lower critical micelle concentration (CMC), higher surface tension and lower foam stability than the other Calfax® products.
