BLEACHING COMPOSITION AND ITS USE

摘要

The liquid bleaching composition comprises:(a) a hypohalite bleach; (b) a pH buffering component in an amount of 0.5-9wt%; and (c) an ingredient having the ability to prevent the precipitation of the salts of the buffering component upon dilution of the composition in water. When the ingredient is a polyacrylate polymer, the polymer is present in an amount of less than 0.5wt%. Also claimed are: (1) a solid bleaching composition comprising: (a) a hypohalite bleach; (b) a pH buffering component; and (c) an ingredient having the ability to prevent the precipitation of the salts of the buffering component upon dilution of the composition in water. Use - The composition is useful in laundry applications such as machine and hand laundry methods. The fabrics are immersed in the bleaching solution formed by diluting the composition in water. Advantage - The ingredient having the ability to prevent the precipitation of the buffering component upon dilution of the composition in water provides improved whiteness and/or safety to the fabrics treated with the composition. The composition is chemically stable and is suitable for bleaching different types of fabrics including natural/synthetic fabrics.
