Hardness salts stabilization effect

Schulze [51] described an extensive study on C12-C14 ether carboxylic acid sodium salt (4.5 mol EO) in terms of surface tension, critical micelle concentration (CMC), wetting, detergency, foam, hardness stability, and lime soap dispersing properties. He found good detergent effect compared to the etho-xylated C16-C18 fatty alcohol (25 mol EO) independent of CaCl2 concentration, there was excellent soil suspending power, low surface tension, and fewer Ca deposits than with alkylbenzenesulfonate. 

These last examples illustrate the effecte of heavy cations on anionic stability. The opposite case of an anionic effect is also possible. Thus diazonium salts are hardly stable but not dangerous when the anion is a chloride ion, whereas they become dangerous when the anion is a sulphide or carboxylate. 

Uses Water treatment formula to prevent buildup of min. scale and to control corrosion in industrial water circuits mainly used in open cooling water systems incorporated additive controls growth of algae and slime bacteria contains no biocides dispersant and cleaning effects protection against corrosion of steel, copper, and copper alloys stabilization of hardness forming salts even at high water temps.
