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.

Application Areas — Detailed

Liquid detergents, dish wash and laundry concentrates

SCS 40% is the standard hydrotrope choice for clear, high-active liquid detergents. It keeps anionic + nonionic surfactant blends single-phase at high active matter, depresses the cloud point so the formula stays clear at low storage temperature, and reduces gel formation when concentrating LAS / SLES / AES surfactants.

Typical dosage 1 – 8% on product weight; 3% is a common starting point at 20% surfactant active matter
Compatible with LAS, SLES, AES, AOS, alpha-olefin sulfonates, alkanolamides, and amphoterics
Reduces viscosity in concentrated APG / amine-oxide systems for easier pumping and bottling
Maintains clarity in dish wash gels containing fragrance, dye, and electrolyte builders

Hard-surface cleaners, degreasers and APCs

In alkaline all-purpose cleaners and metal-degreasing concentrates, SCS 40% couples solvent and surfactant phases at high builder loadings (silicates, carbonates, EDTA, citrate). It tolerates electrolytes better than SXS in the lower-electrolyte cleaner systems and prevents salting-out at the surfactant layer.

Stabilises clear single-phase concentrates with sodium hydroxide, sodium silicate, or sodium metasilicate
Improves rinse-off behaviour and reduces residue on stainless steel, glass, and painted substrates
Used in floor strippers and wax cleaners as a solubiliser for d-limonene, glycol ether, and aromatic solvents

Personal care: shampoos, body wash, liquid soap

SCS 40% is sulfate-free and sulfone-free in its 40% liquid form (sulfate < 1.0%, sulfone < 1.0%) and is acceptable in mild personal-care systems. It clarifies fragrance-loaded SLES / cocamidopropyl betaine systems and is compatible with cationic conditioning agents in 2-in-1 shampoos.

Keeps cloudy fragrances and essential oils in solution at high surfactant concentration
Reduces viscosity in over-thickened SLES systems for accurate pump dispensing
Compatible with Polyquat-7, Polyquat-10, behentrimonium chloride conditioners

Agrochemical EC / SL formulations and adjuvants

SCS 40% acts as a coupling agent in pesticide / herbicide concentrates, helping water-immiscible actives stay solubilised in EC and SL formulations. It improves wetting on hydrophobic leaf surfaces and is permitted as an inert ingredient in non-food pesticide products.

Used in glyphosate, 2,4-D, paraquat, and dicamba formulations as a hydrotrope/wetting aid
Compatible with nonyl-phenol-free emulsifiers and modern alkyl-polyglycoside surfactants
Improves spray-tank dilution stability of high-electrolyte SL concentrates

Oilfield and metal processing applications

In drilling fluids and stimulation fluids, SCS 40% improves the dispersion of polymeric viscosifiers (xanthan, HEC, PHPA) and helps water-soluble actives penetrate oil-bearing formations. In metal processing it is a viscosity reducer for concentrated electroplating bath cleaners and zinc-plating brighteners.

Drilling fluid solubiliser for water-based mud (WBM) and oil-based mud (OBM) brine phases
Cementing-aid coupling agent in oil-well cement slurries
Bath additive in alkaline degreasers, electroplating cleaners, and zinc-plating brighteners

It is used as a coupling agent and viscosity modifier in liquid detergents, dish wash, agrochemical concentrates, and industrial cleaners to keep anionic and nonionic surfactants soluble at high active loadings.

What is the CAS number and molecular formula of Sodium Cumene Sulfonate?+

The CAS number of Sodium Cumene Sulfonate is 28348-53-0, also known as cumenesulfonic acid sodium salt or isopropylbenzenesulfonic acid sodium salt. The molecular formula is C9H11NaO3S and the molecular weight is 222.24 g/mol.

Sodium Cumene Sulfonate 40% liquid vs 90% powder — which should I buy?+

The 40% liquid blends cold and ships best for regional buyers within ~2,500 km of the plant. The 90% powder cuts freight cost per kg active by roughly 60%, making it preferred for long-haul export. Chemistry and CAS are identical — only form factor, handling, and logistics differ.

What is the typical dosage of SCS-40 in liquid detergent?+

Typical dosage of SCS-40 in liquid detergent is 1–8% on product weight depending on surfactant loading and target clarity temperature. A starting point of 3% is common for a 20% active-matter laundry liquid; increase to 5–8% for concentrated formulations above 30% active matter that require a low cloud point.
