Sodium lauroyl sarcosinate

Description

1. Product Overview
Sodium Lauroyl Sarcosinate (SLS) is a high-purity, anionic surfactant derived from natural fatty acids and sarcosine, engineered for superior mildness and foam performance. Its primary industrial use is as a secondary surfactant in premium personal care formulations, including high-end shampoos, facial cleansers, and oral care products. The key value proposition is its exceptional ability to create dense, creamy foam while remaining non-irritating to skin and eyes—significantly outperforming conventional sulfates. Strategically, SLS is critical for formulators transitioning to sulfate-free, bio-based product lines, meeting accelerating global demand for sustainable and mild cleansers.

2. Key Specifications & Technical Characteristics

• Chemical composition: Sodium N-lauroyl sarcosinate (C₁₅H₂₈NNaO₃); derived from lauric acid and sarcosine

• Purity / active matter: ≥95% (anhydrous basis); typical 30% aqueous solution also available

• Physical form: White to off-white powder (anhydrous) or clear to pale yellow liquid (30% solution)

• Particle size (powder): 100% through 40 mesh; ≥85% through 80 mesh

• Bulk density (powder): 0.35–0.55 g/cm³

• pH (10% solution): 7.0–9.0

• Solubility: Freely soluble in water; stable across pH 4.5–9.0

• Packaging options: 25 kg multilayer kraft/PE bags (powder); 200 kg HDPE drums or 1000 kg IBC totes (liquid)

• Shelf life: 24 months when stored in original sealed containers at 5–30°C, away from direct light and moisture

3. Core Industrial Applications

• Primary industries: Personal care & cosmetics; oral care; pharmaceutical topical preparations; high-end household cleaning

• Specific operational use cases:

  • Sulfate-free shampoos & body washes: Functions as primary or co-surfactant delivering rich foam without stripping natural oils

  • Facial cleansers: Provides mildness superior to betaines, preserving skin barrier integrity

  • Toothpaste: Acts as a foaming agent and antimicrobial enhancer, compatible with fluoride and enzymes

• Performance advantages over alternatives:

  • Versus Sodium Lauryl Ether Sulfate (SLES): Significantly lower ocular/skin irritation (OECD 439: non-irritant vs. moderate irritant)

  • Versus Cocamidopropyl Betaine (CAPB): Higher foam volume at lower use concentration (3–5% vs. 8–10%)

  • Provides anti-static and conditioning effects on hair, reducing need for separate conditioning agents by 15–20%

4. Competitive Advantages

• Quality consistency: ISO 9001:2025 certified production; each lot tested for residual lauric acid (<0.5%), sodium chloride (<1.5%), and microbial limits (USP <61>)

• Supply reliability: Multiple redundant manufacturing sites (Asia, Europe, Americas) with 50,000 MT annual capacity; 98.5% on-time-in-full (OTIF) track record

• Logistics capability: Global warehousing network enabling 3–7 day lead times to major industrial hubs (Rotterdam, Singapore, Houston, Shanghai)

• Price competitiveness: Vertically integrated from lauric acid refining; fixed-volume contracts available with price adjustment formulas tied to fatty acid indices

• Sustainability: ≥92% renewable carbon content; readily biodegradable (OECD 301B: 98% in 28 days); RSPO Mass Balance certified lauric acid option available

• Technical support: Full regulatory documentation (TSCA, REACH, IECIC, COSMOS-compliant); formulation optimization support via application lab
