They are alkyl polyethylene glycol ethers based on C10-Guerbet alcohol and ethylene oxide. The Lutensol® XP types are manufactured by reacting the C10-alcohol with ethylene oxide in stoichiometric proportions. The numeric portion of the product name indicates the general degree of ethoxylation. Product properties: Lutensol XP 30, XP 40, XP 50, XP 60, XP 70, XP 80 and XP 90 are clear to cloudy liquids at room temperature, and can form a sediment. Lutensol XP 100 and XP 140 are soft, colorless or slightly yellowish pastes at 23°C; they become clear at 50°C. Lutensol XP 69, XP 79, XP 89 and XP 99 are clear liquids at room temperature. Solubility: Details on the solubility of the Lutensol XP types in various solvents are given in the table below. Biodegradability: The Lutensol XP types are readily biodegradable according to test methods OECD 301 A – F.
