Q1: What is SLES? What are its mainstream specifications?

A1: SLES stands for Sodium Lauryl Ether Sulfate, CAS No.68585-34-2, a widely used anionic surfactant. Our regular export grades include SLES 28%, SLES 60% and SLES 70%.

• SLES 70%: High-concentrated stock liquid, low transportation cost for large manufacturers who have dilution equipment.
• SLES 28% & 60%: Ready-to-use low-concentration products, suitable for small detergent factories without dilution procedures.

Q2: What is the difference between SLES and SDS/SLS?

A2: Compared with SDS (Sodium Dodecyl Sulfate), SLES contains ethoxy groups, which greatly reduces skin and eye irritation. SLS has strong cleaning power but high irritation, only used in industrial degreasing; SLES is milder with rich foam, ideal for shampoo, body wash and household dishwashing liquid.

Q3: Is SLES safe for skin care and food contact detergents?

A3: High-purity SLES with low dioxane content meets international export standards, safe for daily personal care products. It is globally approved for shampoo, facial cleanser and dishwashing liquid that contact food residues. Our factory strictly controls unsulfated matter and impurities to pass EU, Africa and Southeast Asia import inspections.

Q4: What products can SLES be added to? What is the recommended dosage?

A4:

1. Personal care: Shampoo, shower gel, hand sanitizer, bubble bath, facial cleanser, adding amount 8%-18%
2. Household cleaning: Dish soap, laundry liquid, multi-purpose cleaner, adding amount 5%-12%
3. Industrial field: Textile degreasing agent, metal cleaning fluid, pesticide emulsifier It can compound with amphoteric surfactants, nonionic surfactants to enhance mildness and foam performance.

Q5: Does SLES work well in hard water?

A5: Yes. SLES has excellent hard water resistance. Its foaming and decontamination effect will not be weakened by calcium and magnesium ions in hard water, keeping stable cleaning effect in areas with poor water quality such as Africa and the Middle East.

Q6: What is the packaging of SLES? What is the loading volume for one container?

A6:

• Standard package: 210kg plastic drum
• Bulk package: 1000L IBC tote tank
• 20GP container: Load around 10 tons of 210kg drums
• HS Code: 3402390000 Custom small packaging is available upon customer request.
