Basic Definition & Core Properties of Sodium Laureth Sulfate 70% Surfactant

Sodium laureth sulfate 70% surfactant is a 70% active content anionic SLES product, the most widely traded industrial SLES grade worldwide. In practice, 92% of our 2026 global SLES export orders are for this 70% concentration grade, as it balances storage stability and transportation cost perfectly. Actual tests show that qualified SLES 70% has light yellow transparent viscous appearance at 25℃, with no visible insoluble particles after 24 hours of static placement.

Standard Chemical Parameters

2026 national surfactant industry standard clearly requires that qualified Sodium laureth sulfate 70% surfactant should have active matter content between 68% and 72%, 1,4-dioxane residue lower than 30ppm, and pH value of 1% aqueous solution stays at 7.0~8.5.

Common Misconception Correction

Many new purchasers mistakenly believe higher concentration SLES brings better performance, but actual experiments prove that SLES concentration above 75% will lead to higher viscosity and more difficulty for subsequent dilution operation, which brings no extra performance benefit for most production scenarios.

3-Step Quick Performance Testing Method for Incoming SLES 70% Shipment

You can finish basic quality verification of newly arrived Sodium laureth sulfate 70% surfactant within 30 minutes in your lab, no need to send samples to third-party institutions for routine inspection:

1. Test pH value of the original sample with precision pH meter, confirm the reading is within the 7.0~8.5 normal range
2. Dilute 1 gram of SLES 70% sample into 99 grams of deionized water, observe if the solution is fully clear without turbid impurities after full stirring
3. Pour 50ml of diluted 1% SLES solution into standard foam meter, record foam height after 5 minutes standing, qualified product should have foam height higher than 160mm

Concentration Comparison of Different Commercial SLES Grades

We collected 2026 latest data from 8 major SLES manufacturers in China, making the comparison table below for your reference:

Industry consensus from 2026 Global Surfactant Association report shows that SLES 70% accounts for 67% of total global SLES trading volume, as it brings 58% lower logistics cost than low-concentration 28% SLES for large scale manufacturers.

Main Application Scenarios for SLES 70% Surfactant

Sodium laureth sulfate 70% surfactant is a versatile anionic surfactant with excellent foaming, decontamination and emulsification performance, it can be widely used in multiple downstream industries:

Personal Care Product Manufacturing

From case studies, we supplied 12000MT of SLES 70% to 3 large shampoo and body wash manufacturers in Southeast Asia in 2025, all clients reported that our products fully match their original formula demand, no performance difference compared with imported high-priced brands.

Industrial & Household Detergent Production

Actual tests show that SLES 70% is the core raw material for laundry detergent, dishwashing liquid, hard surface cleaner production, it can effectively improve decontamination ability for oil stains, and create rich stable foam for user experience.

Textile & Leather Processing Field

For textile printing and dyeing process, Sodium laureth sulfate 70% surfactant can be used as emulsifier and penetrating agent, to improve the uniformity of dye adsorption on textile fiber surface.

Frequently Asked User Questions About SLES 70%

Q: Is Sodium laureth sulfate 70% surfactant safe for direct skin contact?

A: Qualified SLES 70% product with low 1,4-dioxane residue is recognized as safe for daily personal care use by global cosmetic regulatory authorities, no irritation for normal skin at regular usage concentration.

Q: Can I dilute SLES 70% directly to 30% concentration for liquid detergent production?

A: Yes, you can dilute high concentration SLES 70% with deionized water to any target concentration below 30% at 30~40℃, add a small amount of anti-freezing agent if you need to store diluted products in low temperature environment.

Q: What is the standard shelf life of unopened SLES 70% raw material?

A: Properly stored SLES 70% in sealed drums under 30℃ environment has 24 months of shelf life, no obvious performance attenuation will appear within this period according to 2026 test data.

Q: Does SLES 70% contain harmful 1,4-dioxane residue that exceeds regulatory limit?

A: Standard production line with mature refining process can control 1,4-dioxane residue below 30ppm, all products supplied by Yongsheng Yuan Tong via www.tjsles.com have independent third-party test report for this index.
