Q1: What is the primary chemical nature of Dehypon LST 254?
A: Dehypon LST 254 is a nonionic surfactant based on alkyl polyglucoside (APG) chemistry, offering excellent biodegradability and mildness while maintaining robust surface-active performance in aqueous systems.
Q2: In which types of industrial cleaning formulations is Dehypon LST 254 most commonly used?
A: It is widely applied in low-foaming, high-rinsing industrial cleaners—especially for metal parts cleaning, CIP (clean-in-place) solutions, and precision cleaning where residue control and compatibility with chelants or builders are critical.
Q3: How does Dehypon LST 254 perform in hard water and at elevated temperatures?
A: Thanks to its APG backbone, it exhibits good tolerance to calcium and magnesium ions and maintains effective wetting and solubilization across a broad temperature range, including typical hot cleaning conditions up to 80 °C.
Q4: Is Dehypon LST 254 compatible with common anionic and nonionic co-surfactants?
A: Yes—it shows broad formulation compatibility, particularly with common anionic surfactants like LAS or AES, as well as other nonionics such as alcohol ethoxylates, enabling synergistic cleaning performance without significant phase separation or viscosity instability.
Q5: What is the typical dosage range for Dehypon LST 254 in formulated cleaners?
A: Dosage depends on formulation requirements and desired performance, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—in ready-to-use or concentrate systems.
