Industrial Isopropylamine Dodecylbenzene Sulfonate | CAS 68584-24-7

Isopropylamine Dodecylbenzene Sulfonate for Demanding Industrial Applications

At Royalchem, we supply key chemistries that drive industrial progress. This bulletin provides a technical overview of one of the most versatile products in our portfolio: Isopropylamine Dodecylbenzene Sulfonate (CAS NO. 68584-24-7).

As a high-performance member of the Linear Alkylbenzene Sulfonate (LAS) family, this anionic surfactant is a cornerstone of global industry. Its value is rooted in a powerful combination of cost-effectiveness, robust performance, and established biodegradability. This document is intended for formulators, procurement managers, and industry professionals seeking a reliable surfactant.

Mechanism of Action

The efficacy of Isopropylamine Dodecylbenzene Sulfonate originates from its amphiphilic molecular structure. Each molecule contains a hydrophilic (water-attracting) sulfonate head and a hydrophobic (oil-attracting) alkylbenzene tail.

This dual nature allows it to dramatically lower the interfacial tension between oil and water. At a specific concentration (the Critical Micelle Concentration, or CMC), the molecules self-assemble into "micelles" that encapsulate oil and grease particles, lifting them from the surface and allowing them to be rinsed away. This fundamental mechanism drives its performance in cleaning, emulsification, and wetting applications.

A Technical Note for Formulators and Procurement Managers

A key point of clarity involves the different CAS numbers associated with this product.

• CAS No. 68584-24-7: This refers to the industrial-grade product, which is a mixture of linear alkyl chains (typically C10-C16). This is the standard product used in commercial formulations.

• CAS No. 26264-05-1: This refers to the idealized C12 single molecule, often cited in academic research and for regulatory standards.

Understanding this distinction is crucial for accurately interpreting technical specifications and scientific literature. The core chemical function remains consistent between the two.

Core Applications Across Key Industries

This surfactant's versatility makes it a critical component in some of the world's most demanding sectors.

• Oil & Gas (High-Value Applications):

• Pipeline Flow Assurance: Isopropylamine Dodecylbenzene Sulfonate is a primary active ingredient in advanced pipeline integrity formulations. It functions as a highly effective corrosion inhibitor by forming a protective film on the pipe's internal surfaces. Simultaneously, it prevents the deposition of paraffin wax and asphaltenes, which can restrict flow. Crucially, these formulations can often be injected into live pipelines, eliminating the need for costly shutdowns.

• Enhanced Oil Recovery (EOR): In tertiary recovery operations, this surfactant is used to mobilize residual oil trapped in reservoir rock. It works by radically lowering oil-water interfacial tension and through wettability alteration, shifting the rock surface from "oil-wet" to "water-wet." This allows water flooding to more efficiently displace trapped oil, maximizing asset value.

• Cleaning & Detergents: It is a foundational ingredient in high-performance industrial degreasers, institutional cleaners, and specialty household detergents designed to remove heavy oil and grime.

• Industrial Manufacturing: It serves as a primary emulsifier in emulsion polymerization processes for producing latex, adhesives, and coatings. It also functions as a highly effective dispersing agent for pigments.

• Textiles & Leather: The product is used as a potent degreasing agent for rawhides in leather processing. In textiles, it is applied as an anti-static agent for synthetic fibers like polyester and nylon, preventing static buildup during high-speed manufacturing processes.

Innovation and Sustainable Development

The LAS family is not a static technology; it is continuously evolving to meet modern sustainability standards. Historically, LAS was developed in the 1960s as a readily biodegradable replacement for the environmentally persistent Branched Alkylbenzene Sulfonates (BAS).

Today, the industry is focused on further reducing the carbon footprint of LAS production. Leading manufacturers are pioneering new methods using renewable feedstocks and clean energy.

Furthermore, ongoing research is unlocking next-generation applications for this chemistry in fields such as:

• Advanced quenchants for steel heat treatment.

• High-performance membranes for water desalination and purification.

• Flexible strain sensors for use in smart textiles and wearable electronics.
