Sodium Laureth Sulfate (SLES) – Cosmetic and Industrial Grade Raw Material Supply Guide

Introduction
Sodium Laureth Sulfate (SLES) is a widely used anionic surfactant in the cosmetic, personal care, and industrial cleaning sectors. Known for its excellent foaming properties and effective cleansing ability, SLES has become a staple raw material for shampoo, body wash, facial cleansers, and industrial detergents. As a high-quality SLES cosmetic-grade raw material supplier, we provide reliable, bulk SLES raw materials that meet stringent quality standards for OEM manufacturers, cosmetic formulators, and industrial cleaning product developers. This article provides a comprehensive overview of SLES raw material properties, applications, performance characteristics, and procurement considerations, helping businesses make informed sourcing decisions.

Chemical Properties of SLES

Sodium Laureth Sulfate is a water-soluble anionic surfactant with the chemical formula C₁₂H₂₅(OCH₂CH₂)nOSO₃Na, typically presented as a viscous liquid or paste. SLES is derived from ethoxylated lauryl alcohol, making it slightly milder than Sodium Lauryl Sulfate (SLS) while retaining strong cleansing properties. Key chemical properties include:

• Appearance: Pale yellow to light brown viscous liquid

• Active matter content: 28–30%

• pH value: 6–8 (1% aqueous solution)

• Solubility: Fully soluble in water, compatible with most cosmetic formulations

• Stability: Stable under normal storage conditions; avoid prolonged exposure to high temperatures

Applications of Sodium Laureth Sulfate

SLES is primarily used as a surfactant in both cosmetic and industrial products due to its excellent foaming and cleansing properties. Its major applications include:

1. Cosmetic and Personal Care Industry

   • Shampoo, conditioner, and body wash formulations

   • Facial cleansers and bubble baths

   • Foam-based hand wash and liquid soaps

   • OEM cosmetic production for bulk SLES raw material sourcing

2. Industrial Cleaning

   • Industrial detergents and liquid cleaners

   • Floor cleaning solutions and machine wash detergents

   • Laundry detergents requiring high foaming and emulsification

Advantages of Using SLES in Formulations

SLES provides several benefits for manufacturers and formulators:

• Efficient Cleansing: Removes oils, dirt, and impurities effectively from surfaces and hair.

• High Foaming Capability: Produces rich, stable foam, enhancing consumer perception of cleaning efficacy.

• Mild on Skin Compared to SLS: Lower irritation potential makes it suitable for cosmetic and personal care products.

• Formulation Compatibility: Compatible with various surfactants, thickeners, preservatives, and fragrances.

Comparison with SLS and Other Surfactants

While SLS (Sodium Lauryl Sulfate) is a stronger cleansing surfactant with higher irritation potential, SLES offers a milder alternative suitable for daily-use cosmetic products. In B2B raw material sourcing, choosing between SLES and SLS depends on the end product application:

Quality Standards and Certificates

As a trusted SLES raw material supplier, our products comply with international quality standards and regulations:

• Certificates: MSDS, COA, ISO 9001, Cosmetic-grade compliance

• Purity Levels: Customizable to meet specific OEM formulation requirements

• Packaging: 25kg/50kg drums or customized bulk orders

Procurement Considerations for OEM Manufacturers

When sourcing SLES, OEM manufacturers and industrial buyers should consider:

• Purity and Active Matter Content: Ensures consistent foam and cleansing efficiency.

• Compatibility with Formulations: Check compatibility with other surfactants, preservatives, and thickeners.

• Bulk Supply Capability: Stable inventory and supply chain reliability are critical for continuous production.

• Certificates and Compliance: Required for cosmetic-grade products and regulatory approvals in different markets.

Conclusion

Sodium Laureth Sulfate (SLES) remains a cornerstone anionic surfactant for both cosmetic and industrial applications. Its balanced combination of cleansing power, high foam, and moderate skin mildness makes it ideal for shampoo, body wash, facial cleansers, and industrial detergents.
