Abstract
1. A process for the removal of ethylene oxide and/or propylene oxide and, optionally, dioxane from surface-active derivatives - prepared by ethoxylation and/or propoxylation - of organic compounds containing at least one active hydrogen atom, characterized in that the surface-active derivatives are treated with steam, optionally in vacuo, at temperatures of 70 to 130 degrees C and the steam treated product is optionally dried.
