Alkylaryl sulfonates

Description

1. Product Overview
Alkylaryl sulfonates are high-performance anionic surfactants, recognized globally for their exceptional detergency, wetting, and emulsification properties. Their primary industrial use is as the foundational active ingredient in high-efficiency industrial cleaners, lubricant additives, and enhanced oil recovery (EOR) formulations. The key value proposition lies in their superior stability across hard water, extreme pH, and high-temperature conditions—delivering operational cost reduction and process reliability. Strategically, they are indispensable for industries transitioning to water-based, low-VOC cleaning systems, making them a critical enabler of both regulatory compliance and sustainability roadmaps.

2. Key Specifications & Technical Characteristics

• Chemical composition: Linear or branched alkylbenzene sulfonic acid (neutralized as sodium, calcium, or amine salts)

• Purity level / Grade: Industrial grade (90–96% active matter) / Technical grade (96–98% for EOR applications)

• Physical characteristics:

  • Form: Viscous paste or free-flowing powder (depending on neutralization)

  • Color: Pale yellow to amber (paste); off-white to light tan (powder)

  • Density (paste): ~1.05–1.10 g/cm³ at 20°C

  • pH (1% solution): 7.5–10.5 (depending on counter-ion)

  • Water solubility: Fully dispersible in water; stable in hard water up to 300 ppm CaCO₃

• Packaging options: 200 kg HDPE drums, 1,000 kg IBC totes, 25 kg multi-wall paper bags (powder), or bulk isotanks

• Shelf life: 24 months when stored in sealed containers between 5–40°C, away from oxidizing agents

3. Core Industrial Applications

• Primary industries: Industrial & institutional cleaning, oil & gas (EOR), metalworking fluids, textile processing, agrochemical emulsifiers, and construction chemicals

• Operational use cases:

  • Heavy-duty degreasers for manufacturing floors and automotive parts → outperforms nonylphenol ethoxylates (NPEs) with faster wetting and no endocrine-disruptor risks

  • Enhanced oil recovery (surfactant flooding) → reduces interfacial tension to 10⁻³ mN/m, mobilizing up to 30% additional residual oil vs. water-only injection

  • Metalworking coolants → provides stable emulsion and rust inhibition, extending sump life by 40–60% compared to petroleum sulfonates

• Cost advantage: Lower required use concentration (2–5% active matter vs. 8–10% for conventional nonionics) reduces formulation cost by 15–25% per batch

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified batch-to-batch variability < ±0.5% active matter; each lot tested for free oil, unsulfonated matter, and color stability

• Supply reliability: Multi-continent production (Asia, Europe, GCC) with 50,000 MT annual capacity and contractual safety stock guarantees (30 days coverage)

• Logistics capability: 48-hour dispatch from regional hubs; temperature-controlled containers for paste products; dangerous goods classification (Class 8, PG III) expertly managed

• Price competitiveness: Direct-from-manufacturer pricing with volume-based tiering; formula-linked pricing options available for long-term contracts

• Sustainability: Biodegradable per OECD 301 (ready biodegradability >70% in 28 days); no APEO/NPE content; REACH and TSCA compliant; supports customers’ EPD and green chemistry targets

• Technical support: Dedicated application lab for formulation optimization; free compatibility testing with co-surfactants, builders, and solvents; SDS and regulatory documentation available in 12 languages

5. Commercial & Supply Information
