Patent number: 6211141Abstract: A high-density powdered detergent composition which has a bulk density of 0.6 to 1.2 g/ml and which comprises 0.5 to 30% by weight of (a) a glycine-N,N-diacetic acid derivative, 5 to 45% by weight of (b) a nonionic surfactant having an HLB value of 10.5 to 15.0, 0.5 to 18% by weight of (c) an anionic surfactant and 1 to 30% by weight of (d) an aluminosilicate, each percentage being based on the total weight of the composition, and the weight ratio of the component (b) to the component (c) lying between 90:1 and 60:40. This composition contains both a glycine-N,N-diacetic acid derivative which is a builder excellent in biodegradability and sequestering power and an inorganic builder such as zeolite or crystalline silicate, and exhibits high detergency.Type: GrantFiled: July 13, 1998Date of Patent: April 3, 2001Assignee: Kao CorporationInventors: Shu Yamaguchi, Hiromitsu Hayashi, Masaki Tsumadori, Masaaki Yamamura, Noboru Moriyama

Patent number: 6211131Abstract: Sequestering agents for use as a whitening and fabric strength enhancer for aqueous hypochlorite bleach compositions are provided. It was found that the sequesterants when used with hypochlorite in the presence of soluble heavy metal ions, particularly iron and manganese ions, provide significantly improved whitening and fabric protection. Most preferably, the sequesterants are selected from polyacrylic acid, a polyacrylic acid derivative, a copolymer of acrylic acid or methacrylic acid and a comonomer which is maleic acid or maleic anhydride and mixtures thereof.Type: GrantFiled: November 13, 1997Date of Patent: April 3, 2001Assignee: The Clorox CompanyInventors: Thomas W. Kaaret, William L. Smith
