Q1: What is the primary chemical nature of Lutensol XL 100?
A: Lutensol XL 100 is a nonionic surfactant based on a linear alcohol ethoxylate structure, featuring a balanced hydrophile-lipophile relationship that supports effective wetting, emulsification, and solubilization in aqueous systems.
Q2: In which types of industrial cleaning formulations is Lutensol XL 100 commonly applied?
A: It is frequently used in high-performance industrial and institutional cleaners—especially alkaline and low-foaming formulations—for metal cleaning, CIP (clean-in-place) solutions, and hard-surface degreasers where robust soil removal and compatibility with builders and chelants are required.
Q3: How does Lutensol XL 100 perform under elevated temperature and high-pH conditions?
A: It demonstrates good thermal stability and alkaline resistance, maintaining surfactant functionality in formulations with pH values up to approximately 12.5 and at temperatures commonly encountered in hot cleaning processes.
Q4: Is Lutensol XL 100 compatible with anionic surfactants and common detergent builders?
A: Yes—it exhibits broad compatibility with anionic surfactants (e.g., LAS, AES), phosphates, silicates, carbonates, and polycarboxylates, making it suitable for complex multi-component cleaning systems without significant phase separation or performance loss.
Q5: What is the typical dosage range for Lutensol XL 100 in formulated products?
A: Dosage depends on formulation requirements and application intensity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in final ready-to-use or concentrate systems.
