SLES (Sodium Laureth Sulfate) 70% – Anionic Surfactant Supplier from China
SLES (Sodium Laureth Sulfate) 70% is a widely used anionic surfactant applied in personal care products, household detergents, industrial cleaning formulations, and other chemical applications. It is well known for its excellent foaming ability, detergency, emulsification properties, and compatibility with other surfactants.
The most common commercial product is SLES 70%, also known as SLES N70, which is a high-active paste containing approximately 70% active matter. It is widely used as a primary surfactant in shampoos, shower gels, liquid soaps, hand washes, detergents, and cleaning products.
We supply SLES 70% from China for international customers, importers, distributors, and manufacturers of personal care and detergent products. COA, SDS, TDS, and product specifications can be provided according to customer requirements.
SLES Product Information

SLES is produced by ethoxylation and sulfation of fatty alcohols, followed by neutralization with sodium hydroxide. The number of ethylene oxide (EO) units affects the performance characteristics of the surfactant.
Commercial SLES products are commonly available as SLES 1EO, SLES 2EO, SLES 3EO, and other EO variations. Among them, SLES 70% (commonly SLES 2EO or SLES 3EO depending on manufacturer specification) is the most widely used grade in the detergent and personal care industries.
SLES as an Anionic Surfactant
SLES belongs to the anionic surfactant family. It contains a negatively charged sulfate group that provides strong cleaning and foaming properties.
Compared with traditional sulfate surfactants, SLES provides good detergency while offering better mildness and formulation flexibility when combined with other surfactants.
Its main functions include:
- Cleansing
- Foaming
- Emulsification
- Wetting
- Solubilization
- Viscosity adjustment in formulations
Because of these properties, SLES is one of the most widely used surfactants in modern cleaning and personal care products.
SLES for Shampoo and Personal Care Products
One of the largest applications of SLES is in personal care formulations.
SLES is commonly used in:
- Shampoo
- Shower gel
- Liquid hand soap
- Facial cleanser
- Body wash
- Bubble bath products
In shampoo and body wash formulations, SLES works as the main cleansing and foaming ingredient. It helps remove oil, dirt, and impurities from hair and skin while producing rich foam.
SLES is often combined with other surfactants such as CAPB (Cocamidopropyl Betaine) and nonionic surfactants to improve mildness, foam quality, and overall formulation performance.
SLES for Detergents and Cleaning Products
SLES is widely used in household and industrial cleaning formulations because of its excellent detergency and foaming properties.
Applications include:
- Liquid laundry detergents
- Dishwashing liquids
- Household cleaners
- Industrial cleaning products
- Car wash formulations
In detergent systems, SLES helps remove grease and dirt by reducing surface tension and improving the interaction between water and oily substances.
Its compatibility with other surfactants makes it suitable for complex detergent formulations.
SLES 70% (N70) Advantages
SLES 70% is preferred by many detergent and personal care manufacturers because it provides:
- High active surfactant content
- Excellent foam performance
- Strong detergency
- Good water solubility
- Good compatibility with other surfactants
- Suitable viscosity for formulation processing
- Cost-effective performance
- Wide application range
Compared with lower concentration liquid surfactants, SLES 70% offers advantages in transportation efficiency and storage.
SLES and Other Surfactants
SLES is commonly used together with other surfactants to achieve balanced formulation performance.
SLES vs SLS
Both SLES and SLS are anionic surfactants. SLS (Sodium Lauryl Sulfate) generally provides stronger cleansing and foaming performance, while SLES contains ethoxylated chains that can provide improved formulation flexibility and mildness.
SLES vs CAPB
CAPB is an amphoteric surfactant commonly used together with SLES. CAPB can improve foam stability and reduce the irritation potential of sulfate-based surfactant systems.
SLES vs AEO
AEO (Alcohol Ethoxylate) is a nonionic surfactant mainly used in industrial detergents, emulsification, and cleaning formulations. SLES is more commonly associated with personal care and household detergent applications.
SLES Storage and Handling
SLES should be stored in a cool and dry place away from direct sunlight and extreme temperatures.
Because SLES 70% is a high-active paste, viscosity may change depending on storage temperature. Proper storage conditions help maintain product quality and processing performance.
Before use, customers should confirm compatibility with other formulation ingredients.
