Chemical additives employed to offset the effects of water with an excessive mineral content are called?

• A. Desiccants
• B. Water conditioners
• C. Surfactants
• D. Preservatives

Answer: (B)

When water contains high levels of minerals (hard water), those minerals can interfere with embalming solutions, causing scaling, precipitation, reduced solubility, and less effective chemical action. Additives used to offset these effects are called water conditioners. They work by binding or exchanging the troublesome minerals (for example, chelating agents or ion-exchange softeners), keeping the embalming fluids stable, preventing scale, and allowing chemicals to work as intended. Desiccants remove moisture, surfactants primarily alter surface tension and wetting, and preservatives are for preventing decay; none of these address mineral content in water.
