What is Sodium Lauryl Polyoxyethylene Ether Sulfate

Sodium Lauryl Polyoxyethylene Ether Sulfate, identified by CAS number 9004-82-4, is a widely used anionic surfactant in personal care and cleaning products. Its molecular formula is generally represented as (C2H4O)nC12H26O4S.Na, where the “n” denotes the variable number of ethylene oxide units introduced through a process called ethoxylation.

Chemical Identity and Structure

CAS 9004-82-4 confirms the chemical’s unique identity for regulatory and sourcing purposes.
The molecule combines a hydrophobic lauryl (C12) alkyl chain with a hydrophilic polyoxyethylene (ethylene oxide) chain and a sulfate group, making it an effective surfactant.
The ethoxylation process attaches ethylene oxide units to sodium lauryl sulfate, creating a softer, more water-soluble, and less irritating surfactant compared to unmodified forms.

Anionic Surfactant Properties and Ethoxylation

As an anionic surfactant, Sodium Lauryl Polyoxyethylene Ether Sulfate carries a negative charge on its sulfate group, which helps it to reduce surface tension and interact with oils and dirt.
The ethoxylation step improves its performance by increasing solubility and reducing irritation, making it gentler for skin and eyes while maintaining strong cleansing and foaming properties.
This process also enhances its compatibility with hard water and other formulation ingredients.

Comparison with Sodium Lauryl Sulfate (SLS)

Unlike Sodium Lauryl Sulfate (SLS), which is non-ethoxylated and often harsher, SLES (Sodium Lauryl Polyoxyethylene Ether Sulfate) is known for having better skin tolerance and lower irritation.
Both are strong detergent surfactants and excellent foaming agents, but SLES is preferred in formulations where mildness and biodegradability are important.
SLES is often labeled as Sodium Laureth Sulfate or Sodium Lauryl Ether Sulfate (SLES 70%) in the market, reflecting its ethoxylate content and standard purity.

By choosing Sodium Lauryl Polyoxyethylene Ether Sulfate, formulators gain a highly effective, mild, and biodegradable surfactant trusted across cosmetics, detergents, and industrial applications.

Key Properties and Benefits of Sodium Lauryl Polyoxyethylene Ether Sulfate

Sodium Lauryl Polyoxyethylene Ether Sulfate (SLES) is prized for its excellent chemical properties that make it a go-to anionic surfactant in many formulations. It offers:

Superior emulsification – SLES effectively blends oil and water, ensuring smooth and stable mixtures.
Strong dispersion ability – It distributes particles evenly in solutions, which helps prevent clumping.
Outstanding wetting power – This allows liquids to spread quickly and thoroughly over surfaces, improving cleaning efficiency.
Rich foaming capabilities – SLES creates abundant, stable foam that boosts the sensory experience in personal care and cleaning products.

Performance Benefits

What sets SLES apart from similar surfactants like Sodium Lauryl Sulfate (SLS) is its high biodegradability, which aligns well with eco-conscious regulations and consumer demand in the U.S. market. It also shows:

Low skin and eye irritation compared to SLS, making it gentler for use in shampoos, body washes, and toothpaste.
Resistance to hard water – SLES maintains its performance even in water with high mineral content, important for consistent cleaning results across different regions.

Versatility in Formulation

SLES stands out due to its broad compatibility with other ingredients, allowing it to be easily integrated into complex formulas without destabilizing them. Additionally, it serves as an effective thickening agent, enhancing texture and viscosity in various products.

These key properties make Sodium Lauryl Polyoxyethylene Ether Sulfate a reliable, efficient, and eco-friendly choice for manufacturers targeting both personal care and household cleaning applications in the U.S. market.

How Sodium Lauryl Polyoxyethylene Ether Sulfate Is Manufactured

Manufacturing Sodium Lauryl Polyoxyethylene Ether Sulfate (SLES CAS 9004-82-4) involves several precise steps to ensure high quality and consistent performance. Here’s a straightforward look at the process:

Step by Step Manufacturing Process

Ethoxylation of Lauryl Alcohol
- The process starts with ethoxylation where lauryl alcohol reacts with ethylene oxide. This adds polyoxyethylene groups (–(C2H4O)n–) making the molecule more water-soluble and less irritating compared to non-ethoxylated surfactants.
Sulfation
- Next is the sulfation of the ethoxylated lauryl alcohol. This introduces the sulfate group (–OSO3Na), turning the compound into an anionic surfactant with excellent foaming and cleaning power.
Neutralization
- The sulfated product is then neutralized, usually with sodium hydroxide, to create the sodium salt form that is stable and easy to use in formulations.
Filtration and Purification
- Finally, the product undergoes filtration and purification to remove impurities, ensuring a clear, consistent, and high-performance surfactant.

Raw Materials Sourcing

High-grade lauryl alcohol is sourced primarily from natural oils like palm kernel oil or coconut oil.
Using renewable raw materials supports sustainability and meets increasing demand for eco-friendly chemicals in the U.S. market.

Frequently Asked Questions About Sodium Lauryl Polyoxyethylene Ether Sulfate SLES

What Is the Difference Between SLES and SLS

SLES (Sodium Lauryl Polyoxyethylene Ether Sulfate) and SLS (Sodium Lauryl Sulfate) are closely related anionic surfactants but differ in mildness and structure. SLES is ethoxylated, meaning it contains additional ethylene oxide units that make it gentler on skin and eyes, with lower irritation potential. SLS is more aggressive and can cause dryness or irritation, especially with repeated use. For personal care and household products, SLES is preferred for better skin compatibility and performance in foaming and cleansing.
