TCP also manufacture Sodium Hydrosulphite of higher purity. Quality system of TCP's process is as per ISO 9001.APPLICATIONS:Textile: A Reducing Agent, Dyeing Auxiliary in Vat Dyeing, in 'Reduction Clearing' of Disperse Dyes and in the 'Stripping' of direct colour and as a reduction Bleaching Agent for wool, nylon and cotton. Food: As a preservative. Sugar/Jaggery: For purification as a Bleaching Agent in the removal of organic and other impurities, thereby imparting attractive colour and sweetness to the end product. Jaggery produced by hydros will not become black and will not become semi solid on long storage.Pharmaceutical: Extensively used in reducing reaction and as a Bleaching Agent in the Manufacture of certain Antibiotics and Analgesics.Paper: Used as a Bleaching Agent in Paper and Pulp Industry, for bleaching of mechanised pulps, single stage or for split bleaching. Clay: Hydrosulphite bleaching of clay removes of iron impurities and allows clay to be bleached to perfect whiteness. Sodium Hydrosulphite transforms trivalent iron to bivalent which, on subsequent acid treatment, dissolves and removes iron from the clay. Vat Dyes: Hydrosulphite is used in the manufacture of Vat Dyes. Soap: Hydrosulphite is used in the bleaching of Crude Soap, particularly, in the manufacture of Washing Soaps.
