Sodium Lauryl Ether Sulfate (SLES) | High-Purity Surfactant for Detergents & Personal Care

📌 Detailed Introduction of Sodium Lauryl Ether Sulfate (SLES)

✔ What is Sodium Lauryl Ether Sulfate (SLES)?

Sodium Lauryl Ether Sulfate (SLES) is an anionic surfactant widely used in personal care and household cleaning products. It is derived from natural fatty alcohols and is known for its excellent detergency, emulsification, and foaming abilities. SLES is commonly used in shampoos, liquid soaps, body washes, toothpaste, dishwashing liquids, and industrial cleaners.

✔ CAS Number & Chemical Formula:

• CAS Number: 9004-82-4

• Chemical Formula: C12H25(OCH2CH2)nOSO3Na

📌 Applications of SLES in Various Industries

✔ Personal Care Industry

• Shampoos & Conditioners: Provides excellent foam stability and cleansing while being gentle on the scalp.

• Body Wash & Liquid Soap: Creates a rich, creamy lather with high cleansing power.

• Toothpaste & Oral Care: Used as a foaming and emulsifying agent to improve texture and cleaning efficacy.

✔ Home & Industrial Cleaning

• Dishwashing Liquids & Hand Soaps: Ensures powerful grease removal while being skin-friendly.

• Laundry Detergents & Fabric Softeners: Enhances foaming and dirt removal efficiency in both liquid and powder detergents.

• Car Wash & Hard Surface Cleaners: Provides high foaming action for deep cleaning applications.

✔ Other Industrial Applications

• Textile & Leather Processing: Acts as a wetting and dispersing agent for textile dyes.

• Agricultural Formulations: Used in pesticides and herbicides as an emulsifier.

• Construction & Paints: Enhances emulsion stability in paint formulations.

📌 Production Method & Raw Materials

✔ Raw Materials Used:

• Lauryl Alcohol (Natural or Synthetic)

• Ethylene Oxide (EO)

• Sulfur Trioxide (SO₃) or Chlorosulfonic Acid (CSA)

• Sodium Hydroxide (NaOH) Solution

✔ Production Process:

1. Ethoxylation: Lauryl alcohol is reacted with ethylene oxide to form ethoxylated alcohol.

2. Sulfation: The ethoxylated alcohol undergoes sulfation with SO₃ or CSA.

3. Neutralization: The resulting sulfate is neutralized with NaOH to form SLES.

4. Purification & Standardization: The final product is purified and adjusted to the desired concentration (e.g., SLES 70%).

SLES, or Sodium Lauryl Ether Sulfate, is a widely used surfactant in industrial applications due to its excellent foaming, cleaning, and emulsifying properties. Here's a description of its industrial applications:

1. Detergents and Cleaners: SLES is a key ingredient in various industrial and household cleaning products such as dishwashing detergents, laundry detergents, and all-purpose cleaners. Its ability to produce copious amounts of foam helps in lifting and removing dirt and grime from surfaces effectively.

2. Personal Care Products: SLES is commonly found in personal care products like shampoos, body washes, and soaps due to its ability to create a rich lather and cleanse the skin and hair gently. Its emulsifying properties also help in stabilizing formulations and ensuring even distribution of other ingredients.

3. Textile Industry: SLES is used in textile processing as an emulsifier and detergent. It aids in the removal of oils, dirt, and other impurities from textiles during processes like scouring, bleaching, and dyeing.

4. Emulsion Polymerization: SLES is employed as a surfactant in emulsion polymerization processes to stabilize the dispersion of polymer particles in water. This is crucial in the production of various synthetic latex products, such as paints, adhesives, and coatings.

5. Agricultural Chemicals: SLES is utilized in the formulation of agricultural chemicals such as pesticides and herbicides. It helps in dispersing the active ingredients evenly and enhances their effectiveness.

6. Metal Processing: In industries dealing with metalworking fluids, SLES is used as an emulsifier to facilitate the dispersion of oils and coolants, aiding in the lubrication and cooling of metal surfaces during machining and forming processes.

7. Food Industry: While not as common as in other industries, SLES can also find applications in the food industry. It may be used as a foaming agent or emulsifier in certain food processing operations, though regulations regarding its use in food products are stringent.
