If you work in personal care or household cleaning, you already know SLES is the dependable workhorse. This specific paste-grade, 70% active AES (aka SLES) coming out of Hebei is what a lot of mid-market brands quietly rely on—good performance, consistent foam, sensible price. To be honest, after talking with procurement teams and QC managers, it seems the sweet spot right now is a stable 70% paste with low color and controlled 1,4-dioxane. That’s where 70% SLES Paste Best Price Sodium Lauryl Ether Sulfate has been winning orders.
Two big currents: cost-down reformulations and “mild-enough” cleaning. SLES remains the practical middle ground—more forgiving than SLS, easier to thicken, and friendly with common co-surfactants (CAPB, APGs). Actually, many customers say this paste grade cuts compounding time in shampoos and dish liquids because it dissolves cleanly and builds foam fast.
| Parameter | Typical | Method / Note |
|---|---|---|
| Active matter (as AES) | ≈ 70% | ISO 2271 (two-phase titration) |
| pH (1% aq.) | 7.0–9.5 | Glass electrode |
| Unsulfated matter | ≤ 3.5% | Internal QC |
| 1,4-Dioxane | ≤ 10 ppm (typical) | GC, per client spec; real-world use may vary |
| Color (Klett, 5% sol.) | ≤ 50 | Visual/Klett |
| Shelf life | 18–24 months | Sealed, 5–35°C |
C12–C14 fatty alcohol → Ethoxylation (EO ≈ 2–3) → Sulfation (SO3 or CSA route) → Neutralization with NaOH → Vacuum stripping → Filtration and QC. Key tests: active matter (ISO 2271), foam (ASTM D1173, Ross–Miles), surface tension (GB/T 6368), biodegradability screening (OECD 301B). Certifications commonly requested: ISO 9001, ISO 14001, REACH registration/assistance.
| Vendor | Active | 1,4-Dioxane | MOQ | Lead time | Price | Notes |
|---|---|---|---|---|---|---|
| FIZA (this product) | ≈70% | ≤10 ppm (typ.) | 5 MT | 10–15 days | Best value | 170 kg drums; free sample |
| SEA Supplier A | 68–70% | ≤20 ppm | 8 MT | 2–3 weeks | Low–mid | IBCs optional |
| EU Producer B | 70% | ≤5 ppm | 1 MT | Stock–10 days | Premium | Tight specs; higher cost |
Options usually include EO moles (for mildness/foam tuning), lower dioxane cuts on request, and alternative packs (IBCs or flexi—ask first). Standard is 170 kg drums for safe transport.
A Southeast Asian dishwash blender told me viscosity build was “predictable with salt, no drama.” A mid-size shampoo brand reported switching to 70% SLES Paste Best Price Sodium Lauryl Ether Sulfate trimmed raw cost ≈ 6% and held panel foam scores steady (Ross–Miles, 0.1% sol., ≈150 mm at 0 min).
Store sealed at 5–35°C, avoid freezing; stir before use. Check local cosmetic and detergent regulations; REACH/SDS support generally available. Biodegradability aligns with OECD 301 screening; still, formulation context matters.
If you need reliable AES performance without paying a premium, 70% SLES Paste Best Price Sodium Lauryl Ether Sulfate hits the value/mildness/foam triangle quite well—especially for shampoos, body washes, and dish liquids where consistency is king.
