LONDON – The ZDHC Group has issued a new ‘research list’ which outlines its research and development efforts to prioritise replacements for substances that currently do not have safer alternatives and that are restricted on its recently released manufacturing restricted substance list (MRSL). In the list, the ZDHC also says that for some end-uses there may never be ‘suitable alternatives’ to fluorine-based chemistry for oil and water repellent fabrics.
