Q1: What is the primary chemical nature of Lutensol XL 70?
A: Lutensol XL 70 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 industrial cleaning applications is Lutensol XL 70 commonly used?
A: It is widely employed in high-performance aqueous cleaning systems for metalworking, industrial degreasers, and hard-surface cleaners—particularly where low-foaming behavior, good soil removal, and compatibility with alkaline builders are required.
Q3: How does Lutensol XL 70 perform in hard water conditions?
A: As a nonionic surfactant, Lutensol XL 70 exhibits excellent tolerance to water hardness and remains effective in the presence of calcium and magnesium ions—making it suitable for use in municipal and industrial water supplies without significant loss of performance.
Q4: Is Lutensol XL 70 compatible with anionic and cationic ingredients?
A: Lutensol XL 70 demonstrates broad compatibility with anionic surfactants and many common formulation additives; however, direct blending with strongly cationic species may lead to reduced stability or precipitation, and compatibility testing under intended use conditions is recommended.
Q5: What is the typical dosage range for Lutensol XL 70 in formulated products?
A: Dosage depends on the specific application and desired performance attributes, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight—in final formulations such as cleaners, emulsions, and process aids.
