SLES 70% Paste Market Snapshot, Specs, and Real‑World Performance

If you work in home & personal care, you already know the quiet workhorse behind the foam: SLES. The batch I’ve been tracking lately is 70% SLES Paste Best Price Sodium Lauryl Ether Sulfate — a utility-grade paste that, to be honest, keeps showing up on purchase lists for shampoos, dish liquids, and industrial cleaners.

What’s trending

Buyers are prioritizing lower 1,4‑dioxane residuals, tighter color control, and, surprisingly, better cold-start solubility to minimize batching delays. Lead times matter too. Many customers say they’re willing to pay a hair more if QC data ships with the drum. Actually, that’s smart.

Quick specs (industrial grade)

How it’s made (short process map)

Materials: Fatty alcohol ethoxylates (C12–C14, EO≈2–3), sulfation agent (SO3 or chlorosulfonic acid), NaOH for neutralization, DI water.

1. Sulfation: Ethoxylates are sulfated (continuous SO3 reactor preferred for color control).
2. Neutralization: Sodium salt formed; heat managed to limit byproducts.
3. Paste-up: Concentration adjusted to ~70% active; filtration and polishing.
4. QC: Active by two-phase titration (ISO 2271), pH (GB/T 6368), color (ASTM D1209), 1,4‑dioxane by GC.

Service life: around 12–24 months in sealed drums, 5–35°C, away from acids/oxidizers; real-world use may vary.

Where it’s used

• Shampoos, body washes, hand soaps (primary anionic surfactant; stable foam, good skin feel with the right co‑surfactants).
• Dishwashing liquids and hard-surface cleaners (high foam, grease cutting).
• Textile wetting/scouring; leather, paper auxiliaries; some agrochemical adjuvants.

Performance notes from the floor

In a basic dishwash base (12% actives total), this paste hit target foam height fast and rinsed clean. In fact, viscosity build with salt was predictable—no surprises. A shampoo pilot run needed a touch of cocamidopropyl betaine to soften the feel, which is typical. Many customers say color stability over 8 weeks at 45°C held up well.

Customization and compliance

• Ethoxylation degree and active range tuning for mildness vs foam.
• Low-dioxane grades (
• Documentation: COA, SDS, ISO 9001, and biodegradability statements aligned to OECD 301; anionic-active data per ISO 2271.

Mini case notes

A Southeast Asia dishwash brand shaved 6% off formulation cost by swapping to this paste and still met panel foam targets; another mid-size shampoo plant reported smoother dilution at 25°C (less fisheye formation) after switching supplier. I guess the cleaner sulfation helped.
