On account of its balsamic constituents, _eau de Lavande ambrée_ in being manufactured cannot be mixed with water, as the latter would produce an emulsion which cannot be removed. _Eau de Lavande double_ is used for the toilet, in the wash-water, or the bath. It is very popular, its action upon the skin and nerves being refreshing and stimulating.
