Basic bleaching agent, without optical brightener.
Stabilized reducing agent for bleaching wool, silk, cellulose and polyamide fibers.
The insensitivity to water hardness is a peculiarity of Arostit IT gr and distinguishes it from products that are stabilized with phosphate. The bleached fabrics processed in hard water also remain free of deposits of any kind and retain their natural feel. Hard-water salts contained in cotton are dissolved out, improving the stability of the white effect.
Arostit IT gr bleaches textiles by reducing coloured minor constituents, rendering them colourless and water-soluble. Due to the effective stabilization liquors with Arostit IT gr retain their bleaching effect longer than liquors containing unstabilized dithionite (hydrosulphite)
