Composition, useful as adjuvant for hydraulic binder based on e.g. calcium sulfate, comprises optionally ethoxylated fatty alcohol and mineral support having salt of alkaline/alkaline-earth sulfate excluding barium sulfate

摘要

Composition comprises at least one optionally ethoxylated 12-40C fatty alcohol, and a mineral support comprising salt of alkaline or alkaline-earth sulfate excluding barium sulfate. An independent claim is included for a process for preparation of the composition comprising contacting at least one fatty alcohol and at least one mineral compound at temperature greater than the melting point of the fatty alcohol, and mixing the obtained medium.
