Disodium Lauryl Sulfosuccinate

Description

1. Product Overview

Disodium Lauryl Sulfosuccinate is a secondary anionic surfactant valued for its exceptional mildness and high-foaming capacity, serving as a strategic alternative to harsher sulfates. It is primarily used as a primary or co-surfactant in personal care cleansing products and industrial foam-based cleaners. The key value proposition lies in its ability to deliver rich, stable foam and effective detergency without compromising skin or ocular compatibility. In a market increasingly driven by “gentle but effective” formulations, this product is strategically critical for brands targeting sensitive-skin, baby care, and sulfate-free segments.

2. Key Specifications & Technical Characteristics

• Chemical composition: Disodium Lauryl Sulfosuccinate (C18H30O7S · 2Na)

• Purity level: ≥ 98% active content (anhydrous basis)

• Physical characteristics: White to off-white fine powder; odor: slight characteristic; bulk density: 0.45–0.55 g/cm³; particle size: 95% through 100 mesh

• pH (1% solution): 5.0–7.0

• Packaging options: 25 kg multi-layer paper bags with PE liner; 500 kg super sacks; custom big bags

• Shelf life: 24 months in unopened original packaging, stored below 40°C in dry conditions

3. Core Industrial Applications

• Personal care (baby shampoos, facial cleansers, body washes) – Outperforms SLS/SLES in ocular and dermal irritation scores, enabling “tear-free” claims.

• Oral care (toothpastes) – Provides stable foam with low mucosal irritation vs. sodium lauryl sulfate.

• Industrial foam cleaning (car wash shampoos, foam cannon concentrates) – Superior foam density and stability in hard water compared to betaines or amine oxides.

• Textile & leather processing – Acts as a rewetting and leveling agent with lower foam sensitivity to electrolytes than nonionics.
  Cost advantage: Reduces need for secondary foam stabilizers or opacifiers.

4. Competitive Advantages

• Quality consistency – Batch-to-batch active matter variance < 0.8%; residual lauryl alcohol < 0.1% for odor control.

• Supply reliability – Dual manufacturing sites (Asia, EMEA) with 98% on-time-in-full rate over 36 months.

• Logistics capability – Regional warehousing in US, EU, and ASEAN for 5-day average lead time.

• Price competitiveness – Direct sodium monochloroacetate (SMCA) integration lowers variable costs by 12-15% vs. spot buyers.

• Sustainability – RSPO-certified lauryl alcohol chain; readily biodegradable per OECD 301B.

• Technical support – Full formulation database (pH stability, viscosity synergy with carbomers) and HPLC analytical method transfer package.
