APPLICATIONS
Calcium Dodecyl Benzene Sulfonate serves as an anionic emulsifier in agricultural emulsifiable concentrates containing oil-soluble active ingredients.
Calcium Dodecyl Benzene Sulfonate helps the organic concentrate form an oil-in-water emulsion during dilution.
Calcium Dodecyl Benzene Sulfonate contributes to interfacial stabilization between the solvent-rich droplets and the surrounding water.
Calcium Dodecyl Benzene Sulfonate requires formulation-specific evaluation because emulsification depends on the active ingredient, solvent system, dilution water, and companion surfactants.
Calcium Dodecyl Benzene Sulfonate combines with nonionic surfactants to produce mixed emulsifier systems for agricultural formulations.
Calcium Dodecyl Benzene Sulfonate supplies the anionic component while the nonionic component helps adjust the overall emulsification characteristics.
Calcium Dodecyl Benzene Sulfonate allows formulators to balance concentrate compatibility with performance after water dilution.
Calcium Dodecyl Benzene Sulfonate performs most effectively when the complete emulsifier package is selected for the particular formulation rather than treated as a universal blend.
Calcium Dodecyl Benzene Sulfonate functions as an emulsifying ingredient in agricultural oil dispersions.
Calcium Dodecyl Benzene Sulfonate supports dispersion of the oil carrier into water when the concentrate is diluted for application.
Calcium Dodecyl Benzene Sulfonate can accompany separate dispersants that stabilize suspended active-ingredient particles within the original oil phase.
Calcium Dodecyl Benzene Sulfonate therefore contributes to the dilution behavior of an oil dispersion without necessarily providing every function needed for suspension stability.
Calcium Dodecyl Benzene Sulfonate is incorporated into selected suspoemulsion formulations containing both suspended solids and emulsified liquid components.
Calcium Dodecyl Benzene Sulfonate contributes principally to stabilization of the liquid-liquid interface within these multiphase systems.
Calcium Dodecyl Benzene Sulfonate must be compatible with the dispersants, rheology modifiers, and other ingredients supporting the suspended phase.
Calcium Dodecyl Benzene Sulfonate requires assessment of both emulsion stability and solid-particle behavior during formulation development.
Calcium Dodecyl Benzene Sulfonate provides dispersant functionality in selected wettable powder formulations when supplied in a suitable dry grade.
Calcium Dodecyl Benzene Sulfonate can also contribute to dispersing systems for water-dispersible granules.
Calcium Dodecyl Benzene Sulfonate supports distribution of the formulation components into the dilution water alongside other wetting and dispersing ingredients.
Calcium Dodecyl Benzene Sulfonate must be evaluated for wetting, dispersion, suspensibility, and compatibility with the active ingredient and carrier.
Calcium Dodecyl Benzene Sulfonate offers formulation flexibility when supplied as solvent-free flakes or powder.
Calcium Dodecyl Benzene Sulfonate enables the formulator to choose the solvent system independently instead of accepting the carrier solvent present in a liquid concentrate.
Calcium Dodecyl Benzene Sulfonate supports both dry formulations and conventional solvent-based emulsifier systems through selection of the appropriate physical grade.
Calcium Dodecyl Benzene Sulfonate retains its own handling hazards even when a solvent-free grade eliminates exposure to an accompanying organic carrier.
Calcium Dodecyl Benzene Sulfonate has reported industrial applications as a lubricating agent and corrosion-inhibiting ingredient.
Calcium Dodecyl Benzene Sulfonate brings surface-active sulfonate functionality to selected lubricant and protective-fluid formulations.
Calcium Dodecyl Benzene Sulfonate requires compatibility assessment with the base fluid and the remaining additive package.
Calcium Dodecyl Benzene Sulfonate should not be assumed to provide the alkalinity reserve or grease-thickening performance of an overbased calcium sulfonate system.
Calcium Dodecyl Benzene Sulfonate also serves as a detergent and surface-active ingredient in selected industrial formulations.
Calcium Dodecyl Benzene Sulfonate contributes interfacial activity that can assist the emulsification and dispersion of hydrophobic components.
Calcium Dodecyl Benzene Sulfonate must be selected according to the intended formulation because the calcium salt does not behave identically to the corresponding sodium salt.
Calcium Dodecyl Benzene Sulfonate requires the appropriate grade and applicable authorization for regulated uses, including any pesticide, cosmetic, pharmaceutical, or food-contact application.
DESCRIPTION
Calcium Dodecyl Benzene Sulfonate belongs to the calcium salts of alkylbenzenesulfonic acids.
Calcium Dodecyl Benzene Sulfonate has a nominal composition containing two singly charged dodecylbenzenesulfonate anions for each divalent calcium ion.
Calcium Dodecyl Benzene Sulfonate contains a sulfonate group attached to an aromatic ring and should be distinguished from an alkyl sulfate ester.
Calcium Dodecyl Benzene Sulfonate may contain different alkyl-chain and substitution isomers, so the commercial designation does not necessarily identify one uniquely defined molecular structure.
Calcium Dodecyl Benzene Sulfonate is described in solvent-free form as a white to light yellow solid, with commercial dry grades supplied as flakes or powder.
Calcium Dodecyl Benzene Sulfonate can also be supplied in liquid concentrates whose appearance and flow properties depend on the carrier solvent and active content.
Calcium Dodecyl Benzene Sulfonate therefore has no single concentration, viscosity, or liquid density applicable to every commercial offering.
Calcium Dodecyl Benzene Sulfonate specifications should identify the physical form and solvent composition before numerical properties are compared.
Calcium Dodecyl Benzene Sulfonate exhibits amphiphilic behavior arising from the combination of hydrocarbon-rich groups and ionic sulfonate functionality.
Calcium Dodecyl Benzene Sulfonate can participate in interfacial films and surfactant aggregates rather than behaving solely as individually dissolved molecules.
Calcium Dodecyl Benzene Sulfonate water compatibility depends on composition, concentration, temperature, solvent content, and other surfactants present.
Calcium Dodecyl Benzene Sulfonate apparent dispersion or emulsification in water should therefore be distinguished from a measured equilibrium molecular solubility.
Calcium Dodecyl Benzene Sulfonate commercial grades can differ in active matter, water content, residual acidity, inorganic salts, and solvent content.
Calcium Dodecyl Benzene Sulfonate is assigned skin-irritation, serious-eye-damage, and harmful-if-swallowed classifications in published safety documentation, although classifications vary between supplied grades and jurisdictions.
Calcium Dodecyl Benzene Sulfonate also requires environmental release control because published classifications identify potential harm to aquatic organisms.
Calcium Dodecyl Benzene Sulfonate workplace labeling, protective measures, and transport requirements must follow the current regional safety data sheet for the exact supplied grade.

Skin Contact:
Remove contaminated clothing and wash affected skin thoroughly with soap and water.
Obtain medical advice if irritation persists.
Wash contaminated clothing before reuse.
Eye Contact:
Immediately rinse with gently flowing water for at least 15 minutes, holding the eyelids open.
Remove contact lenses if present and easy to remove, then continue rinsing.
Obtain urgent medical attention because concentrated grades may cause serious eye damage.
Ingestion:
Rinse the mouth if the person is conscious.
Do not induce vomiting.
Contact a poison center or physician promptly, and never give anything by mouth to an unconscious person.
Note to Physicians:
Provide symptomatic and supportive treatment.
Assess exposure to carrier solvents when the supplied grade is a liquid formulation.
