SDBS/LAS 60%:Sodium Dodecyl Benzene Sulfonate

SDBS/LAS 60%: The High-Performance Surfactant Precursor for Cost-Effective Cleaning

Product Overview

SDBS/LAS 60% is an anionic surfactant precursor supplied as a sodium salt, requiring no further neutralization for its primary application. With a high active matter content of ≥60%, it serves as a powerful and cost-effective cleaning agent, establishing itself as the "best-value choice" for heavy-duty household and industrial detergent formulations. Its efficacy is derived from its powerful hydrophobic and hydrophilic structure, which enables superior emulsification and removal of stubborn soils.

Unmatched Cleaning Power Against Stubborn Soils

The core value of SDBS/LAS 60% lies in its exceptional detergency, particularly against challenging, oil-based stains. Its molecular structure efficiently emulsifies and displaces fats, greases, and mineral oils from various surfaces. This makes it the primary workhorse ingredient in laundry powders, heavy-duty liquid detergents, and industrial degreasers, where its high performance-to-cost ratio is unmatched by many alternative surfactants.

Excellent Process Compatibility for Powder Detergents

A key technical advantage of SDBS/LAS 60% is its outstanding stability under demanding manufacturing conditions. It exhibits high tolerance to heat and is perfectly suited for spray-drying processes used in the production of powdered detergents. This allows for its seamless integration into powder granulation. In a typical low-foam machine laundry powder formulation, an inclusion rate of 8% to 12% provides robust cleaning performance without causing excessive sudsing in modern washing machines.

Environmental Compliance: Linear vs. Branched Chain

The environmental acceptability of this surfactant is critically dependent on its chemical structure. Branched-chain Alkylate Sulfonates (LAS, CAS 68411-30-3), known for their poor biodegradability, are now restricted under regulations like the EU Detergent Regulation and REACH. However, SDBS (Sodium Dodecylbenzene Sulfonate, CAS 25155-30-0), which features a linear alkyl chain, is readily biodegradable and complies with current global environmental and safety standards, making it the responsible and compliant choice for modern formulations.
