Features Of Solvay Soprophor S/40 Flakes Surfactant

  1. Non-ionic surfactant based on ethoxylated linear alcohol chemistry for excellent compatibility with ionic and non-ionic systems.

  2. Free-flowing flakes form enables precise dosing, easy handling, and reduced dust generation compared to powder alternatives.

  3. High foaming capacity combined with good foam stability across a broad pH range (pH 4–12).

  4. Outstanding emulsifying and wetting performance in aqueous formulations, even at low concentrations.

  5. Readily biodegradable (OECD 301D compliant), supporting sustainable formulation design.

Typical Applications Of Solvay Soprophor S/40 Flakes Surfactant

  1. Household and industrial hard-surface cleaners requiring balanced detergency and rinseability.

  2. Laundry detergents and pre-treatment agents for enhanced soil removal and fabric care.

  3. Agrochemical adjuvants to improve active ingredient dispersion, spreading, and foliar uptake.

  4. Textile processing auxiliaries for scouring, dye leveling, and finishing baths.

  5. Industrial metal cleaning formulations where low foaming control and corrosion inhibition synergy are needed.
