Features Of Solvay Rhodafac LO-11/ALA Surfactant

  1. Nonionic surfactant based on alkylphenol ethoxylate (APEO-free) and aliphatic alcohol ethoxylate blend.

  2. Excellent wetting, dispersing, and emulsifying performance in aqueous systems.

  3. Low foaming profile suitable for high-shear and continuous industrial processes.

  4. Good compatibility with anionic, cationic, and nonionic co-surfactants and additives.

  5. Stable across a broad pH range (pH 4–12) and tolerant to moderate electrolyte concentrations.

Typical Applications Of Solvay Rhodafac LO-11/ALA Surfactant

  1. Agrochemical formulations — including SC (suspension concentrates), EW (emulsion in water), and OD (oil dispersions).

  2. Industrial cleaning agents for metalworking fluids and heavy-duty degreasers.

  3. Textile auxiliaries — particularly as a leveling and penetration aid in dyeing and finishing baths.

  4. Paints and coatings — used as a stabilizer in pigment dispersion and latex emulsion systems.

  5. Oilfield chemicals — applied in demulsifiers and pipeline flow improvers for crude oil handling.
