SODIUM CUMENESULFONATE


Sodium cumenesulfonate is a solubilizer, coupling agent and cloud point depressant used in heavy duty cleaners, wax strippers and dishwashing detergents, oil field and metal working applications. Sodium cumenesulfonate is a Hydrotrope, solubilizer, coupling agent, cloud point depressant, viscosity reducer, an anti-caking agent in powdered detergent.
Sodium cumenesulfonate is a hydrotope compound, which consists of a hydrophilic part and a hydrophobic part, similar to surfactants. 
These compounds can get dissolved in water. 
They are available in powder as well as liquid form. 
There are several advantages of sodium cumenesulfonate. 
It increases the solubility for less soluble organic matter; lowers the cloud point of aqueous formulated products, effectively promotes the compatibility of various ingredients present in a multicomponent system, and moderates the viscosity of aqueous formulated products. 
Sodium cumenesulfonate is used as a solubilizer and cloud point depressor in wax cleaners, air mist drilling, laundry washing, drilling fluids, stimulation fluids, anti-caking agents, and coupling agents in powdered detergents. 


Sodium cumenesulfonate is a compound that solubilizes hydrophobic compounds in aqueous solutions by means other than micellar solubilization. 
Typically, Sodium cumenesulfonate consists of a hydrophilic part and a hydrophobic part (similar to surfactants), but the hydrophobic part is generally too small to cause spontaneous self-aggregation. 
Sodium cumenesulfonate does not have a critical concentration above which self-aggregation spontaneously starts to occur (as found for micelle- and vesicle-forming surfactants, which have a critical micelle concentration (cmc) and a critical vesicle concentration (cvc)). ,

Instead, some hydrotropes aggregate in a step-wise self-aggregation process, gradually increasing aggregation size. 
However, many hydrotropes do not seem to self-aggregate at all, unless a solubilizate has been added. 
Examples of hydrotropes include urea, tosylate, cumenesulfonate and xylenesulfonate.

The term hydrotropy was originally put forward by Carl Neuberg  to describe the increase in the solubility of a solute by the addition of fairly high concentrations of alkali metal salts of various organic acids. 
However, the term has been used in the literature to designate non-micelle-forming substances, either liquids or solids, capable of solubilizing insoluble compounds.

Applications
Hydrotropes are in use industrially and commercially in cleaning and personal care product formulations to allow more concentrated formulations of surfactants. 
About 29,000 metric tons are produced (i.e., manufactured and imported) annually in the US.
Annual production (plus importation) in Europe and Australia is approximately 17,000 and 1,100 metric tons, respectively.

Common products containing a hydrotropes include laundry detergents, surface cleaners, dishwashing detergents, liquid soaps, shampoos and conditioners.
They are coupling agents, used at concentrations from 0.1-15% to stabilize the formula, modify viscosity and cloud-point, reduce phase separation in low temperatures, and limit foaming.

Hydrotropes. 
Compounds known as hydrotropes are described as amphiphilic substances composed of both hydrophilic and hydrophobic functional groups.
The hydrophobic part of the molecule is a benzene substituted apolar segment (ie, methyl [common name: toluene], dimethyl [common name: Xylene], or isopropyl [common name: cumene] apolar segment). 

The hydrophilic, polar segment is an anionic sulfonate group accompanied by a counter ion (eg, sodium and ammonium). 
This segment is a comparatively short side chain. 
Commercial toluene(and cumene) sulfonates consist of mixtures of 3 isomers (ortho-,meta-, and para-). 
Commercial xylene sulfonic acid consists of mixtures of 6 isomers (ortho,ortho; meta,meta; para,para; ortho,meta; ortho,para; and meta,para).

Sodium cumenesulfonate increases the solubility of less soluble substances (ie, surfactants) in aqueous solution. 
Sodium cumenesulfonate has structures somewhat similar to surfactants, but they are not themselves surfactants. 
The main property of Sodium Cumenesulfonate is related to the minimum hydrotropic concentration, which is defined as the concentration at which Sodium Cumenesulfonate begins to aggregate.
Sodium Cumene Sulfonate inhibits the formation of surfactant liquid crystalline phases by forming mixed micellar structures with surfactants. 
Since the hydrotrope hydrophilic heads are large and their hydrophobic groups are small, they tend to form spherical rather than lamellar or liquid crystalline structures, therefore inhibiting the formation of the latter. 
This destruction or inhibition of the liquid crystalline phase increases the solubility of the surfactant in the aqueous phase and the capacity of its micellar solution to solubilize material

Method of Manufacture
Hydrotropes are produced by sulfonation of an aromatic hydrocarbon solvent (ie, toluene, xylene, or cumene).
The resulting aromatic sulfonic acid is neutralized using an appropriate base (eg, sodium hydroxide, ammonium hydroxide, potassium hydroxide, or calcium hydroxide) to produce the sulfonate or hydrotrope. 
The liquid product is produced in a closed system.

A hydrotrope is a compound that solubilizes hydrophobic compounds in aqueous solutions by means other than micellar solubilization. 
Typically, hydrotropes consist of a hydrophilic part and a hydrophobic part (similar to surfactants), but the hydrophobic part is generally too small to cause spontaneous self-aggregation. 
Hydrotropes do not have a critical concentration above which self-aggregation spontaneously starts to occur (as found for micelle- and vesicle-forming surfactants, which have a critical micelle concentration (cmc) and a critical vesicle concentration (cvc)). 
Instead, some hydrotropes aggregate in a step-wise self-aggregation process, gradually increasing aggregation size. 
However, many hydrotropes do not seem to self-aggregate at all, unless a solubilizate has been added. 
Examples of hydrotropes include urea, tosylate, cumenesulfonate and xylenesulfonate.

Hydrotropes
Hydrotropes are used to adjust the viscosity in a formulation as well as enable control of foaming characteristics.

ELTESOL SC 40
Sodium Cumenesulfonate

ELTESOL SC 40 is an aqueous solution of a sodium cumene sulphonate. 
This product acts as a hydrotrope and may be used to increase the solubility of other compounds. 
In conjunction with non-ionic surfactants, it will raise the cloud point of the solution allowing clear liquids to be obtained at higher temperatures, enabling additional control of the foaming characteristics and performance. 
It may also be used to reduce the viscosity of concentrated surfactants and formulations.

ELTESOL SX 40
Sodium Xylenesulfonate

ELTESOL SX 40 is an aqueous solution of sodium toluene sulphonate. 
This product is an example of a hydrotrope, which when dissolved in water will assimilate molecules of other normally insoluble compounds. 
They, therefore, act as solubilizers, coupling agents and viscosity modifiers in liquid formulations.

Sodium cumene sulphonate (SCS) is an anionic surfactant and acts as hydrotropes to modify solubilities, viscosities, and other properties of surfactants and surfactant formulations.  
SCS is produced by the sulphonation of cumene followed by neutralization with sodium hydroxide.  
Sulphonation step: involves the use of oleum, a solution of SO3 in sulphuric acid.  
Neutralization step:  The generated aromatic sulphonic acid is converted to their respective salts by neutralization with sodium hydroxide to produce the sodium sulphonate.    
The neutralization is conveniently done in water, since the sulphonates, and even more so the short alkyl chain hydrotropes, are generally water soluble to the extent of 30–50%.  
Post‐processing step: can involve a solvent extraction to remove sulphones and chemical bleaching.  
If solvent extraction is done, traces of solvent must be removed by distillation, usually as the azeotrope. 
For a low sulphate product treatment with lime may be necessary.
