Q1: What is the primary function of Lutensol TO 8 in industrial formulations?
A: Lutensol TO 8 is a nonionic surfactant based on linear alcohol ethoxylates, primarily used as a solubilizer, emulsifier, and wetting agent in aqueous systems. It supports stable oil-in-water emulsions and enhances the dispersion of hydrophobic components in cleaning, agrochemical, and industrial maintenance applications.
Q2: How does Lutensol TO 8 compare to other Lutensol TO grades in terms of hydrophilicity and cloud point?
A: Lutensol TO 8 features a moderate ethoxylation level, resulting in balanced water solubility and surface activity. Its cloud point is higher than lower-EO grades like TO 5 but lower than higher-EO variants such as TO 12, making it suitable for applications requiring good low-temperature stability without excessive sensitivity to temperature changes.
Q3: Is Lutensol TO 8 compatible with ionic surfactants and common formulation additives?
A: Yes, Lutensol TO 8 is generally compatible with anionic, cationic, and amphoteric surfactants, as well as typical co-solvents, chelators, and biocides found in industrial cleaners and crop protection concentrates. Compatibility should always be verified experimentally under intended use conditions due to system-specific interactions.
Q4: What are key handling and storage recommendations for Lutensol TO 8?
A: Store in original sealed containers at temperatures between 5 °C and 30 °C, protected from direct sunlight and moisture. Avoid prolonged exposure to freezing conditions, as crystallization may occur and require gentle warming to redissolve. Ensure adequate ventilation during handling, and refer to the Safety Data Sheet for occupational hygiene guidance.
