    LABSA 96% (Linear Alkylbenzene Sulfonic Acid) CAS 27176-87-0

    Linear Alkylbenzene Sulfonic Acid (LABSA 96%, CAS 27176-87-0, EC 248-289-4) is a high-active anionic surfactant raw material used in laundry detergents, dishwashing liquids, hard-surface cleaners, industrial cleaners and related formulations. Active matter, color, acid value, free oil and packaging vary by grade; check compatibility with the intended neutralization or blending process. COA, TDS and SDS are available for the confirmed grade. For liquid detergent systems where a milder ethoxylated anionic surfactant is required, SLES (Sodium Laureth Sulfate) CAS 68585-34-2 is a related product to compare by active matter, viscosity and salt tolerance.

    Product Overview

    Linear Alkylbenzene Sulfonic Acid (LABSA) 96% is a high-active anionic surfactant raw material widely used in detergent and cleaning product formulations. Identified by CAS 27176-87-0, this material is used as an anionic surfactant component in laundry powders, liquid detergents, hand dishwashing liquids, industrial cleaners and related household-cleaning formulations.

    LABSA 96% is an unneutralized linear alkylbenzene sulfonic acid supplied as a viscous brown liquid. When comparing offers, align the test methods for active matter, free sulfuric acid, unsulfonated matter (free oil), water, color and acid value. COA, TDS and SDS are available for the confirmed grade.

    Applications

    LABSA 96% is widely applied in the following areas:

    • Laundry Detergent: Key anionic surfactant in powder and liquid laundry formulations.
    • Dishwashing Liquid: Anionic surfactant component for hand dishwashing liquid formulations.
    • Industrial Cleaners: Degreasers, hard surface cleaners, and institutional cleaning products.
    • Textile Auxiliaries: Scouring, wetting, and dyeing assistants in textile processing.
    • Emulsion Polymerization: Emulsifier and stabilizer in polymer production.

    For related anionic detergent surfactant raw materials, see SLES (Sodium Laureth Sulfate) CAS 68585-34-2 and Sodium Alpha-Olefin Sulfonate (AOS).

    Packaging & Storage

    Packaging varies by grade, quantity and destination. Follow the supplied SDS and product-specific storage conditions, and keep containers tightly closed when not in use.

    FAQ - Technical & Supply Chain

    • Q:

      Is LABSA 96% already neutralized?

      A: No. LABSA 96% is supplied in its acid form, not as sodium LAS. Neutral or alkaline detergents normally use its neutralized salts; suitably designed acidic cleaners may use the acid form. The chosen base, neutralization level and final pH depend on the formulation.
    • Q:

      Which specifications matter when comparing LABSA 96% offers?

      A: Compare active matter, free sulfuric acid, unsulfonated matter (free oil), water, colour and acid value using agreed test methods. Anionic-active matter can be measured by two-phase titration (ISO 2271), while ASTM D4711 addresses sulfonic and sulfuric acids. Align the calculation basis, including average molecular mass where required. LABSA 96% denotes a commercial active-matter grade, not 96% chromatographic purity.
    • Q:

      Can LABSA 96% replace SLES in a detergent?

      A: LABSA is not a drop-in replacement for SLES. In typical neutral or alkaline detergents it is used as a neutralized alkylbenzene sulfonate, while SLES is an ethoxylated sulfate surfactant. Compare formulations at the same active-matter level and assess foam, viscosity, electrolyte response and stability. The two surfactants can also be used together.
