POWDER BLEACH DETERGENT COMPOSITION

摘要

To provide a bleach detergent composition in the form of a powder suitable for use in bleaching hard surfaces such as dishes and cooking utensils, which has better composition storage stability and better available oxygen stability in aqueous solution, less scale production and better corrosion resistance, and better bleaching power and detergency regardless of the extent of hard components in aqueous solution. A powder bleach detergent composition, characterized by including (A) 25 to 85 mass% peroxide compound, (B) 0.3 to 2.5 mass% poly- alpha -hydroxyacrylic acid and/or salt thereof, (C) 0.5 to 5 mass% high molecular weight polymer, being a homopolymer and/or copolymer with monomer structural units selected from acrylic acid, methacrylic acid, and maleic acid, (D) 0.4 to 2 mass% anionic surfactant and/or nonionic surfactant, and (E) 10 to 30 mass% carbonate.
