Q1: What is the primary chemical nature of Lutensol XL 80?
A: Lutensol XL 80 is a nonionic surfactant based on ethoxylated linear alcohols, specifically designed with a balanced hydrophilic-lipophilic profile to deliver effective solubilization and emulsification in demanding industrial formulations.
Q2: In which types of cleaning or process applications is Lutensol XL 80 most commonly used?
A: It is widely employed in high-performance industrial and institutional cleaners—especially alkaline heavy-duty cleaners, metalworking fluid emulsifiers, and textile processing auxiliaries—where stable emulsions, low foaming, and good hard water tolerance are required.
Q3: How does Lutensol XL 80 perform in cold-water formulations?
A: Thanks to its optimized ethoxylation pattern, Lutensol XL 80 exhibits good water solubility and dispersion stability even at lower temperatures, making it suitable for ambient- or cold-water cleaning systems without significant loss of performance.
Q4: Is Lutensol XL 80 compatible with anionic and cationic surfactants?
A: As a nonionic surfactant, Lutensol XL 80 generally demonstrates good compatibility with anionic surfactants in formulated systems. Compatibility with cationics should be evaluated case-by-case, as interactions may occur depending on concentration, pH, and ionic strength.
Q5: What is the typical dosage range for Lutensol XL 80 in industrial cleaner concentrates?
A: Dosage depends on formulation requirements, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in ready-to-use or concentrate systems where emulsification and soil suspension are critical.
