70% SLES Paste Best Price Sodium Lauryl Ether Sulfate — insider notes, specs, and real-world use

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.

At a glance

• Model: 02 | Grade: Industrial | Other names: AES, Alcohol Ether Sulfate | CAS: 9004-82-4
• Appearance: White to yellowish paste; Odor: Odorless; Trademark: FIZA
• Pack: 170 kg drums (standard); MOQ: 5 MT; Sample: free (nice touch)
• Origin: Zhongyuan Building, No.368 Youyi North Street, Shijiazhuang, Hebei, China | HS Code: 340239

Why it’s trending

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.

Typical technical specifications

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

Process flow (condensed)

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.

Applications that actually work

• Shampoo/body wash: pairs well with CAPB for mildness; stable viscosity with NaCl.
• Dishwash liquids: fast foam break-and-recovery; good grease cut.
• Laundry gels and car wash: high, dense foam; tolerant to hard water when blended.
• Industrial cleaning, textiles, and emulsion polymerization as primary anionic surfactant.

Vendor snapshot (price/fit, informal)

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

Customization and packaging

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.

Field feedback (short and honest)

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).

Handling & compliance

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.

Bottom line

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.
