1. Product Description

Sodium Lauryl Ether Sulphate 70% (SLES 70%) is a widely used anionic surfactant designed for personal care products, household detergents, and industrial cleaning formulations. It provides effective cleansing, foaming, and wetting properties, making it a key ingredient in a broad range of liquid and semi-liquid cleaning products.

Supplied as a white viscous paste, SLES 70% has an active matter content of 70% ± 2.0%. Its concentrated formulation makes it suitable for manufacturers seeking an efficient surfactant ingredient for detergent and personal care applications.

SLES 70% is commonly used in shampoos, body washes, hand washes, dishwashing liquids, laundry detergents, and multipurpose cleaners. It can be formulated alone or combined with other surfactants, depending on the desired cleansing performance, foam characteristics, viscosity, and overall product formulation.

2. Chemical & Physical Properties

SLES is valued for its surface-active properties, which help reduce surface tension, support wetting, and facilitate the removal of dirt and oily residues. Its foaming and cleansing performance makes it suitable for a variety of aqueous cleaning systems.

The product is supplied in a concentrated form. Appropriate mixing procedures and formulation adjustments may be required when incorporating it into finished products.

3. Specifications

The above specifications are based on the supplied product quality standard. Batch-specific test results can be verified through the corresponding Certificate of Analysis (COA).

4. Applications

4.1 Personal Care Products

SLES 70% is widely used as a cleansing and foaming ingredient in rinse-off personal care formulations.

• Shampoos: Helps remove sebum, dirt, and styling product residues from hair and the scalp. It contributes to foam formation and can be combined with amphoteric or nonionic surfactants to adjust cleansing performance and formulation characteristics.

• Body Washes and Shower Gels: Provides cleansing and foam generation, helping remove perspiration, surface oils, and everyday impurities from the skin.

• Liquid Hand Washes: Functions as a primary or co-surfactant in hand-cleansing formulations, supporting effective washing and a rich lather.

• Facial Cleansers: Can be used in selected rinse-off facial cleansing formulations. The concentration and surfactant blend should be carefully designed to meet the intended skin-feel and mildness requirements.

• Bubble Baths and Bath Products: Helps generate foam in bath formulations, depending on the overall composition and use concentration.

In personal care products, SLES is often combined with ingredients such as Cocamidopropyl Betaine (CAPB) to modify foam characteristics, viscosity, and the sensory properties of the finished formulation. Finished products should be evaluated for skin compatibility and intended-use requirements.

4.2 Household Cleaning Products

SLES 70% is suitable for a range of household cleaning formulations that require effective detergency and foaming.

• Dishwashing Liquids: Helps remove food residues and grease from dishes, cookware, and kitchen utensils. Its foaming properties are useful in hand dishwashing formulations.

• Laundry Detergents: Can serve as a surfactant component in liquid laundry detergents, supporting the removal of everyday soil and oily stains. Its suitability depends on the complete formulation and the intended washing conditions.

• Multipurpose Cleaners: Can be incorporated into selected household surface cleaners for removing common dirt and greasy residues from washable surfaces.

• Kitchen Cleaners: Contributes to the cleansing action of formulations intended for worktops, sinks, and other washable kitchen surfaces.

• General Household Detergents: Can be blended with other surfactants, builders, hydrotropes, and functional ingredients to achieve the required cleaning performance and product stability.

The final formulation should be assessed for foam level, rinsability, viscosity, stability, and compatibility with other ingredients.

4.3 Industrial and Institutional Cleaning

SLES 70% can also be used in selected commercial and institutional cleaning products.

• Commercial Dishwashing and Manual Cleaning Products: Provides foaming and detergency in formulations intended for manual cleaning operations.

• Janitorial Cleaning Formulations: Can be incorporated into certain floor cleaners, washable-surface cleaners, and general-purpose cleaning products, depending on the required foam profile.

• Equipment and Surface Cleaning: May be used as a surfactant component in aqueous cleaning formulations designed to remove routine dirt and oily residues from compatible surfaces.

• Cleaning Concentrates: Its concentrated active matter content makes it suitable for manufacturers producing surfactant-based concentrates that are diluted or further formulated before use.

For low-foam industrial cleaning systems, the suitability of SLES should be assessed carefully because it is a foaming surfactant. Compatibility with the substrate, cleaning equipment, and wastewater treatment requirements should also be considered.

4.4 Detergent and Surfactant Formulations

SLES 70% can function as a primary surfactant or as part of a mixed surfactant system.

• Surfactant Blends: Can be combined with amphoteric surfactants, such as Cocamidopropyl Betaine (CAPB), or selected nonionic surfactants to adjust foam, cleansing performance, and formulation properties.

• Liquid Cleaning Bases: Suitable for use in surfactant bases developed for shampoos, hand washes, dishwashing liquids, and other aqueous detergents.

• Customized Formulations: Formulators can adjust the surfactant ratio, salt content, pH, and other ingredients to achieve the desired viscosity, stability, and user experience.

The recommended dosage depends on the finished product, the required active surfactant level, and the properties of the other formulation ingredients. Laboratory testing is recommended before commercial production.
