SLES 70% (Sodium Lauryl Ether Sulphate)

Sodium Lauryl Ether Sulphate (SLES), also written as Sodium Lauryl Ether Sulfate or Sodium Laureth Sulfate, is an anionic surfactant used for detergency, foaming, wetting and emulsification. Sinoright supplies SLES 70% under CAS 9004-82-4 as a white or light yellow viscous paste at 25°C. The standard specification is 70 ± 2% active matter.

The main documented product is SLES 70% 2EO. Its current representative batch records 70.2% active matter, 1.50% unsulphated matter, 0.60% sodium sulphate and 11 ppm 1,4-dioxane. Buyers can also request 1EO or 3EO according to their formulation requirements. Every grade should be validated in the buyer's own surfactant system before commercial production.

Three packaging formats are available: 170 kg drums, 220 kg plastic drums and 1,100 kg IBCs. The MOQ is 10 MT, LCL orders are supported, and a 200 g evaluation sample can be dispatched within 3 days after the request is confirmed.

SLES 70% is a concentrated, ethoxylated anionic surfactant. Its high active-matter content allows formulators to transport and store less water than with more dilute surfactant solutions. The material is supplied as a viscous paste, so handling and formulation conditions should keep the product temperature between 15°C and 40°C.

The EO designation refers to the nominal ethoxylation level. It can influence foaming, viscosity response and mildness in a finished formulation. Because these effects also depend on co-surfactants, electrolytes, pH and the complete formula, EO selection should be confirmed through formulation testing rather than treated as a guaranteed finished-product result.

No single molecular formula or molecular weight is shown on this page because commercial SLES is a distribution of alkyl-chain and ethoxylation components rather than one discrete molecule.

These descriptions are industry-level selection guidance, not Sinoright-specific comparative test results. Request the applicable grade documentation and test the selected EO level in your complete formulation.

The table combines the agreed product specification with actual results from representative batch 20251112.

The pH condition is stated as a 1% aqueous solution so buyers can compare the result on the same basis. The 1,4-dioxane result is reported in ppm, not percent. The downloadable file beside the product gallery is the representative batch COA for this page; the applicable batch documentation is provided for each order.

Personal Care Formulations

SLES is used as a primary or co-surfactant in shampoos, shower products, hand washes and liquid cleansing systems. It contributes detergency, foam generation and emulsification. The suitable EO grade and use level depend on the required mildness, foam profile, viscosity target and the other surfactants in the formula. Conduct stability, compatibility and skin-appropriateness testing on the finished formulation before scale-up.

Household and Institutional Cleaning

SLES 70% is used in dishwashing liquids, liquid detergents and liquid soaps where foaming, wetting and soil removal are required. Its response can change with water quality, builders, electrolytes, solvents and nonionic or amphoteric co-surfactants. Add the material under controlled mixing and confirm the final pH, viscosity and storage stability in the complete formulation.

Textile Processing

In textile applications, SLES can be used as a wetting, cleaning and emulsifying component in suitable liquid systems, including dyeing-related processes. Performance depends on the fibre, dye system, water hardness, temperature and other auxiliaries. Buyers should confirm compatibility and working concentration through laboratory trials before plant use.

The payment method applicable to a specific order is confirmed during commercial negotiation. Shipment timing is quoted according to the selected EO grade, packaging, quantity and current availability.

 

• Maintain the product temperature between 15°C and 40°C during storage.
• Keep the packaging tightly closed in a well-ventilated storage area.
• Protect the product from freezing, excessive heat and strong oxidizing agents.
• Avoid prolonged or repeated skin contact and follow the handling instructions in the SDS.
• Shelf life is 24 months in the original sealed packaging under the recommended conditions.

SLES 70% is handled as general cargo for transport. Buyers should review the current SDS and their destination-market requirements before shipment and use.

The page's single downloadable document is the representative batch COA, positioned beside the product images. This gives buyers direct access to the active matter, unsulphated matter, sodium sulphate, pH, 1,4-dioxane and color results used on this page.

TDS and SDS/MSDS can be provided during an inquiry or order. REACH, RSPO, ISO 9001 and Halal documentation can also be provided on request, subject to the supplied grade and current document validity. 

Sinoright International Trade Co., Ltd. was founded in 2011 and serves more than 1,000 industrial customers across 80+ countries. For SLES sourcing, buyers receive a practical combination of documented batch data, grade selection and export coordination:

1. COA-backed specification: the page shows both agreed limits and actual results from batch 20251112, including 11 ppm 1,4-dioxane.
2. EO selection: 2EO is fully documented, while 1EO and 3EO can be requested for different formulation priorities.
3. Flexible export quantities: LCL is supported from a 10 MT MOQ, with three packaging options up to 1,100 kg IBCs.
4. Evaluation support: a free 200 g sample can be dispatched within 3 days after confirmation; the buyer only covers courier cost.
5. Commercial flexibility: T/T, L/C, D/P and D/A are supported, with the applicable terms confirmed for the order.

Is this SLES supplied at 70% active matter?

Yes. The specification is 70 ± 2% active matter. Representative batch 20251112 recorded 70.2%.

Which CAS number is used for this product?

The CAS number used consistently on this page and in the current SDS/MSDS is 9004-82-4.

Which EO grade should I select?

2EO is the main documented grade and provides a balanced selection point for foaming, viscosity response and mildness. 1EO is available when foam and viscosity building are priorities, while 3EO is available when enhanced mildness is the priority. Final selection must be confirmed in the complete formulation.

What is the 1,4-dioxane limit and actual result?

The specification limit is ≤30 ppm. Representative batch 20251112 recorded 11 ppm. This result appears in the downloadable COA.

What is the MOQ, and do you support LCL?

The MOQ is 10 MT, and LCL shipments are supported. Available packaging includes 170 kg drums, 220 kg plastic drums and 1,100 kg IBCs.

Can I receive a sample before ordering?

Yes. A 200 g sample is free of charge; the buyer pays courier cost. It can be dispatched within 3 days after the sample request is confirmed.

How should SLES 70% be stored?
