Sodium Cumene Sulfonate (SCS) CAS 28348-53-0

What Sodium Cumene Sulfonate Is

Sodium cumene sulfonate is a short-chain aromatic sulfonate salt with the formula C9H11NaO3S, made by sulfonating cumene (isopropylbenzene) and neutralizing with sodium hydroxide. It is sold as white to off-white crystalline powder or flakes and as a ready-to-use aqueous solution. The molecule is too short to foam or remove soil by itself. It works by hydrotropy: in water it couples surfactants, electrolytes and organic additives that would otherwise separate, so concentrated liquid products stay clear and pourable, pour at lower viscosity and tolerate high salt or alkali loads. SCS and sodium xylene sulfonate are the two standard hydrotropes to choose between. UATChem supplies both powder and solution grades, with active matter and appearance reported on the COA and TDS for each lot.

Detergent, Cleaning and Formulation Use

• Liquid detergents and dishwash. Solubilizes surfactants and electrolytes, keeps concentrated laundry and dish liquids clear and single phase, and reduces viscosity for easy pouring.
• Hard-surface and industrial cleaning. Stabilizes high-alkali, high-salt hard-surface, metal cleaning and CIP formulas that would otherwise cloud or separate.
• Textile. Coupling and dye-solubilizing aid in level dyeing, scouring and wetting baths.
• Agrochemical and personal care. Hydrotrope in soluble liquid and emulsifiable concentrates, and a viscosity and clarity aid in shampoos and body washes.

SCS is commonly evaluated side by side with sodium xylene sulfonate (SXS), the other main aromatic hydrotrope; the choice depends on the formula, electrolyte load and target cloud point.

Typical Specifications

SCS is sold in powder, flake and aqueous solution forms that differ in active matter, so the active level, color and clarity are confirmed on the TDS and COA; the physical constants below identify the material.

Packaging, Documents and Ordering

• Powder and flakes are packed in 25 kg bags or drums; aqueous solution ships in 25 kg or 200 kg drums and IBC totes. Packages stay sealed in a cool place, and liquid grades are protected from freezing.
• Every lot carries a TDS and COA with active matter, color and clarity, together with an SDS; formulation samples and small trial packs can be discussed at inquiry.
• For a quote, UATChem needs the form (powder, flakes or solution), active matter grade, quantity, packing and destination port.

FAQ

Q: What is sodium cumene sulfonate used for?

A: It is an anionic hydrotrope that keeps formulas clear and single phase and cuts viscosity in concentrated liquid detergents.

Q: Is SCS a surfactant that cleans by itself?

A: No, it is a short-chain hydrotrope with little foam or detergency, helping surfactants and salts dissolve and stay stable.

Q: Powder or liquid sodium cumene sulfonate, which to choose?

A: Powder or flakes suit dry blends; the solution doses straight into liquid products, both with grade-specific COA from UATChem.
