Sodium C10-13 alkyl benzenesulfonate

Sodium C10-13 alkyl benzenesulfonate (CAS 68411-30-3) is an anionic surfactant derived from linear alkylbenzene sulfonic acid, neutralized with sodium.

Where is Sodium C10-13 alkyl benzenesulfonate used?

• Household and institutional cleaning: primary active ingredient in liquid and powder detergents, dishwashing formulations, and all-purpose cleaners
• Textile processing: scouring and wetting agent that removes oils, sizing agents, and contaminants from fiber and fabric before dyeing or finishing
• Leather processing: degreasing baths that prepare hides for tanning
• Paper manufacturing: pulp processing and surface treatment for fiber dispersion
• It breaks down grease and soils at low concentrations.
• Component of air-entraining admixtures for concrete and cement mortars.
• Emulsifier in emulsion polymerization for synthetic latex and polymer dispersions.
• Used in agricultural chemicals to improve wetting, spreading and adherence of pesticides and herbicides to plant surfaces.

Formulation notes

• Reacts with acids, producing toxic and corrosive fumes, notably sulfur oxides.
• Shows synergism with non-ionic products in the washing process.
• Stable in mixtures with all nonionic and amphoteric surfactants but not compatible with cationic compounds and enzymes.
• Present in toilet blocks on the French market at concentrations between 20 and 50% by mass.

Typical specification

• Water solubility of 25 g/100 ml at 20°C.
• Available as a delaminating semi-liquid paste; delamination does not affect product properties.
• Resistant to hydrolysis in alkaline media, allowing preparation of strongly alkaline cleaning agents for professional use.
• Foaming properties can be controlled using sodium soaps and foam suppressors.

Regulatory status

• Not subject to restriction under EU REACH.
• Listed as REACH-registered in the public ECHA CHEM database (EC 270-115-0).

Storage, packaging and handling

• Store in an area without drains or access to sewers, separated from acids.
• Primary packaging material is HDPE.
