Sodium 2-ethylhexyl Sulfate CAS 126-92-1

Physicochemical Properties

The secret to its performance lies in its branched $C_8$​ 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.
