Quick answer

Sodium Cumene Sulfonate 40% (SCS-40) is a clear, aqueous hydrotrope solution (CAS 28348-53-0) containing 40 ± 1% active matter. It improves the solubility of non-polar surfactants in water-based formulations, reduces cloud point, lowers viscosity, and stabilises clear liquid detergents, dish wash concentrates, agrochemical EC/SL formulations, and industrial cleaners.

About Sodium Cumene Sulfonate 40%

Sodium Cumene Sulfonate 40% (SCS 40%) is a high-performance liquid hydrotrope used as a coupling agent, solubiliser, and viscosity reducer in surfactant-based formulations. It enhances the aqueous solubility of sparingly soluble organic compounds — such as surfactants, fragrances, and dyes — preventing phase separation, cloudiness, and gel formation in concentrated liquid detergents, industrial cleaners, and personal care products. SCS 40% is sulfate-free and sulfone-free, making it suitable for mild and sensitive-skin formulations. Also known as sodium isopropylbenzenesulfonate or sodium 4-(propan-2-yl)benzenesulfonate, it is a versatile ingredient used across household, industrial, oilfield, and agrochemical applications. Manufactured by Vasudev Chemo Pharma at our ISO 9001:2015 certified facility in Gujarat, India, this product is exported to detergent manufacturers, personal care formulators, and specialty chemical companies worldwide.

Frequently Asked Questions

What is Sodium Cumene Sulfonate 40% and what does it do?+
Sodium Cumene Sulfonate 40% (SCS 40%, CAS 28348-53-0) is a high-performance hydrotrope supplied as a clear aqueous solution containing approximately 40% active sodium 4-isopropylbenzenesulfonate. It functions as a coupling agent, solubiliser, and viscosity reducer in surfactant-based formulations. By disrupting the ordered structure of surfactant micelles, SCS 40% keeps high-surfactant-concentration products — liquid detergents, industrial cleaners, and personal care formulations — clear, stable, and pourable even at low temperatures. Vasudev Chemo Pharma manufactures SCS 40% at our ISO 9001:2015 certified facility in Gujarat, India, and exports it to cleaning product manufacturers and chemical formulators worldwide.
What is the difference between Sodium Cumene Sulfonate 40% and 90%?+
SCS 40% is a ready-to-use aqueous solution ideal for direct addition to liquid formulations — it blends easily, requires no pre-dissolution, and is preferred by detergent and personal care manufacturers for ease of handling. SCS 90% is a concentrated powder (flake/granule) that delivers more active content per kilogram, reducing freight costs for large-volume buyers, but must be dissolved before use. Both grades share the same active ingredient (CAS 28348-53-0) and hydrotropic performance. Choose SCS 40% for convenience and formulation speed; choose SCS 90% for lower shipping cost per unit of active content.
How does Sodium Cumene Sulfonate 40% work as a hydrotrope?+
A hydrotrope increases the aqueous solubility of sparingly soluble organic compounds — such as surfactants, fragrances, and dyes — without forming micelles of its own. SCS 40% achieves this by intercalating between surfactant molecules at concentrations above the minimum hydrotrope concentration (MHC), disrupting liquid crystal and gel phases that cause cloudiness, phase separation, or excessive viscosity. This makes it invaluable in formulating concentrated liquid detergents, all-purpose cleaners, and personal care products where clarity, stability, and low viscosity are critical quality attributes.
Is Sodium Cumene Sulfonate 40% safe for personal care and household products?+
Yes. SCS 40% is biodegradable and non-toxic at formulation-use concentrations. It is widely used in shampoos, liquid soaps, body washes, and household cleaning products globally. It is classified as a mild irritant — prolonged undiluted contact may cause skin or eye irritation (GHS07, H315/H319) — so standard handling precautions (gloves, goggles) are recommended during manufacturing. In finished consumer products at typical use levels (5–15%), it poses no significant safety concern. Vasudev Chemo Pharma provides a full Safety Data Sheet (SDS) with every shipment.
What is the CAS number of Sodium Cumene Sulfonate 40%?+
The CAS (Chemical Abstracts Service) Registry Number of Sodium Cumene Sulfonate 40% is 28348-53-0. The molecular formula is C₉H₁₁NaO₃S with a molecular weight of 222.24 g/mol. The HS code for international trade is 29041090.
What grades of Sodium Cumene Sulfonate 40% are available from Vasudev Chemo Pharma?+
Vasudev Chemo Pharma supplies Sodium Cumene Sulfonate 40% in the following grades: Technical Grade, Industrial Grade. Grade selection depends on your application requirements — contact our technical team for guidance on the best grade for your process.
