Used for wool and silk dyeing, also can be used for leather dyeing.
Primarily wool, silk and nylon (acid dyeing). It can be used on leather and in aqueous ink formulations with proper auxiliaries and fixation.
Slightly soluble in cold water but dissolves readily in hot water; warm to ~60–80°C for stock solutions and add slowly with agitation for even dispersion.
Good light and wash/perspiration fastness on protein fibers when properly exhausted and fixed; results depend on substrate and mordanting conditions.
Light sensitive and may cause irritation—use PPE and consult the SDS. Treat dye wastewater per local regulations to avoid environmental release.
