Q1: What is the primary function of Lutensol XP 70 in industrial formulations?
A: Lutensol XP 70 is a nonionic surfactant based on ethoxylated linear alcohols, primarily used for its excellent wetting, emulsifying, and solubilizing properties in aqueous systems—especially where low-foaming performance and good temperature stability are required.
Q2: Is Lutensol XP 70 suitable for use in low-temperature applications?
A: Yes, Lutensol XP 70 exhibits good low-temperature stability and remains fluid and homogeneous down to approximately 0 °C, making it appropriate for formulations intended for cold-climate use or winter-grade products.
Q3: How does Lutensol XP 70 compare to other Lutensol XP grades in terms of hydrophilicity and cloud point?
A: As a mid-range grade in the XP series, Lutensol XP 70 offers balanced hydrophilicity—higher than XP 45 but lower than XP 90—resulting in a moderate cloud point that supports versatility across both ambient and mildly elevated processing temperatures.
Q4: Can Lutensol XP 70 be used in combination with anionic surfactants?
A: Yes, Lutensol XP 70 is generally compatible with common anionic surfactants such as alkyl sulfates and alkylbenzene sulfonates, enabling synergistic performance in cleaning and emulsification applications—though compatibility should always be verified experimentally under specific formulation conditions.
Q5: What are typical dosage ranges for Lutensol XP 70 in industrial cleaning concentrates?
A: Dosage depends on formulation requirements, but Lutensol XP 70 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve effective wetting and soil removal without excessive foaming.
