What Is Sodium Lauryl Sulfate 70%?

Sodium Lauryl Sulfate 70% (SLS 70%) is a high-concentration anionic surfactant typically supplied in powder, needle, or granular form. It is produced through the sulfation of fatty alcohols, delivering strong detergency, excellent wetting ability, and high foaming performance.

Compared to lower concentration liquid grades such as SLS 28%, SLS 70% provides significantly higher active matter content, allowing manufacturers to optimize transportation efficiency, reduce formulation cost, and control dosing in large-scale production systems.

Due to its strong cleaning power and cost-performance advantages, SLS 70% is widely used in laundry detergents, industrial cleaning agents, and powder-based formulations where high efficiency and low cost per active ingredient are critical.

Key Functions

Sodium Lauryl Sulfate 70% serves as a high-performance anionic surfactant, delivering strong detergency, powerful foaming capability, and efficient soil removal in industrial and detergent applications.

Strong Detergency and Cleaning Power
Provides aggressive removal of oils, grease, and heavy dirt through high surface activity. It effectively breaks down and lifts contaminants from fabrics, hard surfaces, and industrial equipment.
High Foaming Performance
Generates abundant and fast-forming foam, even at low concentrations. This enhances cleaning efficiency and improves performance in laundry and industrial washing systems.
Excellent Wetting Ability
Reduces surface tension rapidly, allowing water to spread and penetrate surfaces more effectively. This improves contact between cleaning solutions and contaminants.
Efficient Emulsification Capability
Helps disperse and suspend oils and greasy substances in water, preventing re-deposition and improving overall cleaning performance.
Suitable for Powder and Solid Formulations
Supplied in powder or needle form, SLS 70% is ideal for dry blending processes such as laundry powders and solid detergent systems.
Cost-Efficient High Active System
With high active matter content, SLS 70% reduces dosage requirements and lowers cost per unit of effective surfactant in bulk industrial production.

Applications

Sodium Lauryl Sulfate 70% is widely used as a primary anionic surfactant in industrial cleaning and detergent systems due to its strong cleaning performance and high concentration.

Laundry Detergent Powders
Used as a core surfactant in washing powders to deliver strong cleaning performance, foam generation, and effective removal of stains and dirt from fabrics.
Industrial Cleaning Agents
Applied in degreasers and heavy-duty cleaning formulations where removal of oils, grease, and industrial residues is required.
Hard Surface Cleaners
Provides strong detergency for cleaning floors, tiles, and equipment surfaces in commercial and industrial environments.
Car Wash and Vehicle Cleaning
Used in car wash formulations for effective removal of dirt, road grime, and oily residues while producing visible foam.
Textile and Industrial Processing
Functions as a wetting and cleaning agent in textile processing and industrial washing systems where fast penetration and cleaning are required.

FAQs

What is the difference between SLS 70% and SLS 28%?

SLS 70% is a high-concentration powder or needle form designed for industrial use and dry formulations, while SLS 28% is a liquid form suitable for direct use in personal care and liquid cleaning products.

Why is SLS 70% preferred in detergent powders?

Due to its solid form and high active content, SLS 70% is easy to handle in dry blending processes and provides strong cleaning performance with lower dosage requirements.

Is SLS 70% suitable for personal care formulations?

SLS 70% is generally not used directly in personal care products due to its high concentration and potential irritation. It is more commonly used in industrial and detergent applications.

How does SLS 70% perform in hard water conditions?

SLS 70% maintains good cleaning performance but may experience reduced foaming in very hard water. This can be improved by adding chelating agents or formulation adjustments.

How does SLS 70% compare to SLES in industrial and detergent applications?

Sodium Lauryl Sulfate (SLS 70%) offers stronger detergency and faster wetting performance, making it suitable for industrial cleaning and detergent formulations. In comparison, Sodium Lauryl Ether Sulfate (SLES) is milder due to ethoxylation and is mainly used in personal care and liquid products. SLS 70% is preferred for cost-efficient, high-performance cleaning, while SLES is selected when mildness is required.
