What is Sodium Cumene Sulfonate SCS CAS 28348-53-0 used for?

Sodium Cumene Sulfonate is a low-molecular-weight aromatic hydrotrope used mainly in concentrated liquid detergents, hard-surface cleaners and degreasers. It helps keep surfactants, builders, fragrances and other hydrophobic components dissolved in a clear, stable formulation.

What is the difference between SCS-40 liquid and SCS-90 powder?

SCS-40 is supplied as a liquid, commonly around 40% active sodium cumene sulfonate, while SCS-90 is a higher-active powder form. They contain the same hydrotrope chemistry but differ in active content, water balance and handling, so the grade should match the formulation and processing route.

Is Sodium Cumene Sulfonate a surfactant or a hydrotrope?

It is an anionic aromatic sulfonate that is frequently classified as a surfactant, but its main industrial function is hydrotropic coupling. Unlike a typical long-chain detergent surfactant, it works by promoting solubility and phase stability rather than acting as the primary foaming or cleaning agent.

How does SCS improve concentrated cleaner stability and viscosity?

SCS disrupts liquid-crystalline and gel structures that can form in high-active surfactant systems, reducing viscosity and improving pourability and cold-temperature clarity. It also couples ingredients that would otherwise separate in built alkaline or electrolyte-loaded cleaners.

Which Sodium Cumene Sulfonate specifications should formulators confirm?

Confirm the supplied form, active content, appearance, pH range, water solubility, residual inorganic content and the stated test method. For liquid grades, also check density and the specific solids basis; for powder grades, confirm assay and moisture limits against the intended formulation.

CAS: 28348-53-0.

Molecular formula: C9H11NaO3S.

It is supplied as SCS-40 liquid or SCS-90 powder according to grade.

It is positioned as a detergent hydrotrope for concentrated liquid cleaners and degreasers.

It helps keep surfactants, builders, fragrances and other hydrophobic components dissolved in a clear, stable formulation.

It disrupts liquid-crystalline and gel structures in high-active surfactant systems.

It reduces viscosity and improves pourability and cold-temperature clarity.

It couples ingredients that would otherwise separate in built alkaline or electrolyte-loaded cleaners.

SCS-40 is a liquid commonly around 40% active, while SCS-90 is a higher-active powder.

It is an anionic aromatic sulfonate whose main industrial function is hydrotropic coupling rather than primary foaming or cleaning.

Confirm supplied form, active content, appearance, pH range, water solubility, residual inorganic content, and test method.

Store in tightly closed containers in a cool, dry, well-ventilated area, away from moisture and direct sunlight.

Use suitable PPE when handling the material to prevent skin or eye contact and dust or mist exposure.

Confirm packaging suitable for the physical form and order quantity, and follow the current SDS.
