[ What is claimed is:] [1.] A process of bleaching fabrics with a composition selected from the group consisting of:1) a liquid bleaching composition comprising:a) a hypohalite bleach in an amount of from 2% to 20% by weight,b) a pH buffering component in an amount of 0.5% to 5% by weight, andc) fro

[ What is claimed is:] [1.] A process of bleaching fabrics with a composition selected from the group consisting of:1) a liquid bleaching composition comprising:a) a hypohalite bleach in an amount of from 2% to 20% by weight,b) a pH buffering component in an amount of 0.5% to 5% by weight, andc) from 0.001% to 0.3% by weight of an ingredient having the ability to prevent the precipitation of the salts of said buffering component upon dilution of the composition in water; wherein said ingredient is a polymer selected from the group consisting of polyacrylate polymers, co-polymers of acrylic acid and maleic acid, co-polymers of styrene sulphonic acid and maleic acid, and mixtures thereof; wherein said ingredient has a molecular weight of from 4,000 to 100,000; and wherein said liquid bleaching composition is suitable for use in laundry applications which provide improved fabric safety and whiteness to fabrics treated therewith, and2) a solid bleaching composition comprising:a) a hypohalite bleach in an amount of from 20% to 95% by weight,b) a pH buffering component, andc) from 0.01% to 3% by weight of an ingredient having the ability to prevent the precipitation of the salts of said buffering component upon dilution of the composition in water; wherein said ingredient is a polymer selected from the group consisting of polyacrylate polymers, co-polymers of acrylic acid and maleic acid, co-polymers of styrene sulphonic acid and maleic acid, and mixtures thereof; wherein said ingredient has a molecular weight of from 4,000 to 100,000; and wherein said solid bleaching composition is suitable for use in laundry applications which provide improved fabric safety and whiteness to fabrics treated therewith;where said fabrics are immersed in a bleaching solution formed by diluting said composition in water.
