What is Sodium Xylene Sulfonate CAS 1300-72-7?

Sodium Xylene Sulfonate, also called SXS or sodium xylenesulfonate, is an anionic hydrotrope and coupling agent with CAS 1300-72-7, EC No. 215-090-9, and molecular formula C8H9NaO3S. It is used mainly in aqueous detergent and cleaning formulations.

What does Sodium Xylene Sulfonate do in a detergent formulation?

SXS helps improve solubility, clarity, and compatibility between surfactants, fragrances, oils, and other formulation components. It may also reduce cloud point or viscosity in suitable liquid systems, making it useful as a formulation-balancing aid.

Is Sodium Xylene Sulfonate a primary surfactant?

It is normally used as a hydrotrope, solubilizer, and coupling agent rather than as the main cleansing surfactant. It is combined with primary surfactants and builders to support a stable, clear liquid formulation.

What supply forms and active contents are common for Sodium Xylene Sulfonate?

Commercial SXS may be supplied as a white powder, crystal, or light-colored aqueous solution. Common liquid grades include about 40% and 45% active content, while dry powder or granule grades may be around 90% active or higher; the exact solids and grade should be confirmed before dosage calculation.

How is Sodium Xylene Sulfonate different from Sodium Cumene Sulfonate or other sulfonates?

SXS and sodium cumene sulfonate are both hydrotropes, but they have different aromatic structures and performance profiles in electrolyte-rich systems. They are not interchangeable with primary sulfonate surfactants such as alpha-olefin sulfonate or dodecyl benzene sulfonate, so selection should be based on the target formulation.
