Product Introduction
SLES-70% (Sodium Lauryl Ether Sulfate) is a high-performance anionic surfactant widely used in personal care, household cleaning, and industrial cleaning formulations. It is valued for its excellent foaming, cleansing, emulsifying, and wetting properties, making it an effective and versatile surfactant for a broad range of applications.
SLES 70% offers an excellent balance between cleaning performance, foam generation, formulation flexibility, and cost efficiency. Its high active matter allows formulators to achieve the desired cleaning and foaming performance at relatively low usage levels.
Due to its versatility and performance, SLES 70% is commonly used in the manufacture of shampoos, liquid hand washes, body washes, shower gels, dishwashing liquids, liquid detergents, household cleaners, and various industrial cleaning products.

Industrial Applications
1. Personal Care Products
SLES 70% is widely used in shampoos, body washes, shower gels, liquid hand soaps, facial cleansers, and bath products. It provides excellent cleansing and rich, stable foam and can be combined with amphoteric and nonionic surfactants to achieve the desired formulation performance.
2. Household Cleaning Products
Commonly used in dishwashing liquids, liquid laundry detergents, multipurpose cleaners, surface cleaners, and bathroom cleaners. It provides effective detergency and helps remove oils, grease, and other soils.
3. Industrial & Institutional Cleaning
Applications include car wash shampoos, industrial detergents, hard-surface cleaners, institutional cleaning products, and general-purpose degreasers. SLES can also contribute wetting, emulsification, and soil-removal properties in cleaning formulations.
4. Textile & Leather Industry
Can be used as a wetting agent, dispersing aid, cleaning agent, and degreasing component. It is applicable in selected textile processing, dyeing, and leather-cleaning formulations.
5. Agricultural & Agrochemical Formulations
SLES 70% may be used as a surfactant, wetting agent, or formulation aid in selected agrochemical formulations to improve dispersion and surface wetting.
Key Benefits
Excellent foaming: Produces rich and stable foam.
Strong detergency: Provides effective cleansing and soil removal.
Good water solubility: Easily incorporated into aqueous formulations.
Versatile: Suitable for personal care, household, institutional, and industrial applications.
High active matter: 70% active concentration provides efficient formulation performance.
Cost-effective: Offers a good balance between performance and formulation cost.
Biodegradable: Readily biodegradable under applicable standard test conditions.
Safety & Handling
- Avoid direct contact with eyes and prolonged contact with skin.
- Wear appropriate protective gloves, safety goggles, and protective clothing during handling.
- Avoid splashing during transfer and dilution because SLES can generate significant foam.
- In case of eye contact, rinse thoroughly with clean water and seek medical attention if irritation persists.
- Follow the product Safety Data Sheet (SDS) for detailed handling, storage, and emergency procedures.
Packaging
SLES 70% can be supplied in:
- 220 kg HDPE drums
- 1,000 kg IBC containers
- Bulk tanker loads, subject to customer and transportation requirements
Storage
Store SLES 70% in tightly closed, clean containers in a cool, dry, and well-ventilated area. Protect the product from direct sunlight, excessive heat, and contamination.
Avoid prolonged storage at very low or very high temperatures, as temperature fluctuations can affect the product's appearance, viscosity, and handling characteristics.
Recommended storage temperature: approximately 20–40°C, unless otherwise specified by the manufacturer's validated storage data.
