Sodium 2-ethylhexyl Sulfate CAS 126-92-1

Sodium 2-ethylhexyl Sulfate CAS 126-92-1 is a branched anionic surfactant chemically defined as the sodium salt of 2-ethylhexyl hydrogen sulfate , functioning primarily as a low-foaming wetting agent in alkaline industrial cleaners and electroplating baths. Also known as Sodium etasulfate or Sodium isooctyl sulfate, this compound is utilized to reduce surface tension in high-electrolyte solutions and serves as a hydrotrope in the formulation of fruit washing solutions and textile mercerizing agents. We provide professional access to this material with competitive factory pricing and the ability to meet customized specifications for various manufacturing requirements. Our commitment to technical transparency ensures that every shipment is accompanied by comprehensive MSDS, TDS, COA documentation to support your quality assurance protocols, and we maintain capacity for consistent bulk supply to facilitate large-scale industrial operations.

Product Description

Physicochemical Properties

The secret to its performance lies in its branched C8​ structure. Unlike linear chains, the 2-ethylhexyl branch prevents tight molecular packing, which grants it exceptional solubility even when the water is saturated with salts or alkalis.

Application Fields: Where It Excels

This surfactant isn’t just a “detergent”; it is a functional additive used where others cannot survive.

  • Industrial & Institutional (I&I) Cleaning: It is the “gold standard” for heavy-duty degreasers. If your cleaner contains high levels of Sodium Hydroxide (caustic soda) or phosphates, CAS 126-92-1 ensures the formula remains stable and the surface is properly wetted.
  • Textile Industry (Mercerizing): During the mercerization of cotton, fabric is treated with highly concentrated caustic baths. This surfactant acts as a powerful penetrant, ensuring the caustic soda reaches the fiber core instantly and evenly.
  • Metal Finishing & Electroplating: In acid or alkaline pickling, it acts as a low-foaming wetting agent. It helps clean metal surfaces of oils and scales more efficiently before the plating process begins.
  • Agrochemicals: It serves as a wetting agent in pesticide and herbicide concentrates, especially those with high salt loads, ensuring even coverage on leaf surfaces.

Safety Precautions

While widely used, Sodium 2-ethylhexyl Sulfate is a concentrated industrial chemical and requires standard professional handling:

  • Eye Protection: It is a significant eye irritant. Always wear chemical safety goggles when handling the 40% concentrate.
  • Skin Care: Prolonged contact can cause irritation or dryness due to its powerful de-fatting properties. Use chemical-resistant gloves (Nitrile or PVC).
  • Ingestion/Inhalation: Avoid breathing mists if the product is sprayed. If swallowed, rinse the mouth and seek medical attention immediately.
  • Documentation: Always refer to the latest Safety Data Sheet (SDS) provided with your shipment for specific local regulatory compliance.

Storage Conditions & Shelf Life

To ensure the product maintains its clarity and performance, follow these storage protocols:

  • Temperature: Store in a cool, dry place between 5°C and 35°C.
    • Note: Exposure to temperatures below 0°C may cause the product to become cloudy or solidify. This is usually reversible by gentle warming and stirring without affecting the chemical properties.
  • Container Compatibility: Use plastic (HDPE), fiberglass, or stainless steel containers. Avoid prolonged storage in untreated carbon steel to prevent discoloration and iron contamination.
  • Seal Integrity: Keep the container tightly sealed. Evaporation of water from the 40% solution can lead to pH shifts or crystallization at the liquid line.
  • Shelf Life: Under ideal conditions in original unopened packaging, the product typically remains stable for 12 months.

FAQ - Technical & Supply Chain

  • Q:

    How is Sodium 2-ethylhexyl Sulfate (CAS 126-92-1) chemically distinguished from Sodium Lauryl Sulfate (SLS)?

    A: Sodium 2-ethylhexyl Sulfate is identified by CAS 126-92-1 and possesses a short, branched C8 carbon chain structure. This distinguishes it from the linear C12 chain of Sodium Lauryl Sulfate, resulting in significantly lower foaming properties and superior stability in high-concentration alkaline or electrolyte solutions suitable for industrial rather than cosmetic applications.
  • Q:

    What is the primary industrial application of Sodium 2-ethylhexyl Sulfate in surface treatment?

    A: In surface treatment and electroplating formulations, this material is intended for use as a wetting agent. It is added to processing baths to ensure uniform coverage and rapid wetting of metal surfaces, particularly in alkaline degreasing or acid pickling steps, without generating excessive foam.
