What Is Sodium Lauryl Ether Sulfate 70%?

Sodium Lauryl Ether Sulfate 70% (SLES 70%), also known as Sodium Laureth Sulfate (AES), is a high-concentration anionic surfactant produced through the ethoxylation of fatty alcohols followed by sulfation and neutralization.

Compared to lower concentration grades, SLES 70% is supplied in a viscous paste form with significantly higher active matter content, allowing manufacturers to dilute it according to specific formulation requirements. It offers a balanced combination of strong detergency, stable foaming performance, and good emulsification capacity, while maintaining better mildness compared to traditional sulfates such as SLS.

Due to its high concentration and formulation flexibility, SLES 70% is widely used as a core raw material in detergent production, industrial cleaning systems, and intermediate surfactant bases for personal care formulations.

Key Functions

Sodium Lauryl Ether Sulfate 70% functions as a core anionic surfactant, delivering strong cleaning performance, stable foam behavior, and reliable formulation compatibility across various applications.

Primary Detergency Performance
Provides effective removal of oils, grease, and particulate dirt through strong surface activity. It reduces surface tension efficiently, allowing water to penetrate and lift contaminants from surfaces, which is critical in both household and industrial cleaning formulations.
Rich and Stable Foam Formation
Generates dense, fine, and long-lasting foam even after dilution. This foam stability enhances cleaning efficiency and improves user perception in applications such as dishwashing liquids and liquid detergents where foam persistence is important.
Emulsification and Degreasing Capability
Effectively breaks down and disperses oily and greasy substances into water-based systems. This ensures contaminants remain suspended and can be rinsed away easily, making it particularly suitable for kitchen cleaning and industrial degreasing formulations.
High Water Solubility and Process Compatibility
Easily dissolves after dilution and integrates smoothly into liquid systems. It supports efficient large-scale production processes, including automated batching and continuous mixing systems.
Formulation Compatibility with Co-Surfactants
Works well with amphoteric and nonionic surfactants such as Cocamidopropyl Betaine (CAPB), allowing formulators to adjust viscosity, foam structure, and mildness to meet different product positioning requirements.
Cost-Performance Balance in Bulk Systems
Due to its high active content, SLES 70% enables manufacturers to reduce the dosage of raw materials per unit of finished product, achieving a more cost-efficient formulation without compromising performance.

Applications

Sodium Lauryl Ether Sulfate 70% is widely used as a primary surfactant raw material in detergent manufacturing, industrial cleaning, and intermediate formulations due to its high concentration and formulation flexibility.

Liquid Detergent Manufacturing
Used in the production of laundry liquids and concentrated detergents where strong cleaning performance and cost control are required. Its high active content allows flexible dilution and formulation scaling.
Dishwashing Liquids
Provides excellent grease-cutting ability and foam stability, ensuring effective removal of food residues and oils while maintaining consistent performance during use.
Household Cleaning Products
Applied in hard surface cleaners, all-purpose cleaners, and kitchen cleaning formulations where reliable detergency and emulsification are essential.
Industrial Cleaning Systems
Suitable for degreasers and industrial cleaning agents that require strong removal of heavy oils and contaminants, especially in manufacturing and maintenance environments.
Personal Care Base (Intermediate Use)
Used as a concentrated base material that is diluted and further formulated into shampoos, body washes, and liquid soaps, enabling manufacturers to control final product composition and cost structure.

FAQs

What makes SLES 70% different from other SLES grades?

The key difference lies in active matter concentration. SLES 70% is a high-concentration paste designed for industrial dilution, allowing manufacturers to optimize transportation, storage, and formulation cost compared to lower concentration liquid grades such as SLES 28%, which is typically supplied as a ready-to-use liquid for direct formulation.

Is SLES 70% suitable for personal care formulations?

Yes, but it is typically used as an intermediate raw material. It must be diluted and combined with co-surfactants and additives before being incorporated into final personal care products.

Is SLES 70% compatible with other surfactants?

SLES 70% shows excellent compatibility with amphoteric and nonionic surfactants such as Cocamidopropyl Betaine, allowing formulators to adjust foam performance, viscosity, and mildness.

Does SLES 70% meet environmental and regulatory requirements?

SLES is considered readily biodegradable and complies with widely accepted environmental standards for surfactants used in household and personal care applications.
What quality parameters should buyers focus on?

Key indicators include active matter content, sodium sulfate level, unsulfated matter, and 1,4-dioxane content. These parameters directly affect formulation stability, product safety, and compliance with international standards.
