Sodium Lauryl Ether Sulfate (SLES) is a chemical compound that has become indispensable in modern product formulations, particularly within the cleaning and personal care industries. Its unique molecular structure as an anionic surfactant allows it to perform multiple functions, from creating luxurious lather to effectively lifting dirt and oils. NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of supplying high-quality SLES, ensuring your products benefit from its exceptional attributes.

Understanding the Chemical Makeup of SLES

At its core, SLES is characterized by a hydrophilic (water-attracting) sulfate head and a hydrophobic (oil-attracting) fatty alcohol tail. The 'ether' in its name refers to the ethoxylation process during its manufacturing, where ethylene oxide units are added to the fatty alcohol chain. This ethoxylation step is critical, as it modifies the surfactant's properties, making it milder on the skin and more soluble in water compared to non-ethoxylated counterparts like SLS. The typical CAS number associated with SLES is 68585-34-2.

Key Properties Driving SLES Usage

The popularity of SLES can be attributed to a combination of beneficial properties:

  • Detergency: Its primary function is to clean by reducing surface tension, allowing water to penetrate and lift away impurities.
  • Emulsification: SLES effectively stabilizes mixtures of immiscible liquids, such as oil and water, which is vital in creating homogenous products.
  • Foaming: It is renowned for producing a dense, stable foam, which enhances the consumer's perception of cleaning power and product efficacy.
  • Wetting: SLES improves the ability of liquids to spread over surfaces, aiding in more efficient cleaning and application.
  • Compatibility: It is compatible with a wide array of other surfactants, including non-ionic and amphoteric types, offering formulators great flexibility.
  • Hard Water Resistance: SLES performs well even in the presence of hard water ions, maintaining its foaming and cleaning efficacy.
  • Biodegradability: SLES is readily biodegradable, making it an environmentally sound choice.

Diverse Applications Across Industries

The versatility of SLES makes it a preferred ingredient in numerous applications:

  • Personal Care: From shampoos and body washes to facial cleansers and toothpaste, SLES provides the necessary lather and cleaning action.
  • Household Cleaners: It is a key component in dishwashing liquids, laundry detergents, and surface cleaners, valued for its grease-cutting power.
  • Industrial Processes: In the textile industry, SLES serves as a wetting agent and emulsifier in dyeing and finishing processes. It also finds use in the leather and petroleum industries.
