Abstract:
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.

This composition contains both an organic builder excellent in biodegradability and an inorganic builder, and exhibits high detergency.
Abstract:
A high-density granulated detergent composition having a bulk density of 0.6 to 1.2 g/ml, which comprises 0.5 to 30 wt.% of an aspartic acid-N,N-diacetic acid salt (a), 20 to 50 wt.% of an anionic surfactant (b) and 1 to 30 wt.% of an aluminosilicate (d), each percentage being based on the total weight of the composition, and which further contains a nonionic surfactant (c) having an HLB value of 10.5 to 15.0 in an amount of 0.5 to 25 parts by weight per 100 parts by weight of the component (b). This composition contains an organic builder excellent in biodegradability together with an inorganic builder and exhibits high detergency.
Abstract:
A super-heavy oil emulsion fuel is formed by emulsification using 100 parts by weight of super-heavy oil, 30-80 parts by weight of water, 0.01-4 parts by weight of an anionic surface activating agent, and a nonionic surface activating agent having an HLB (hydrophilic lipophilic balance) of 9-19 at an anionic surface activating agent/nonionic surface activating agent weight ratio of 1/99-75/25. The super-heavy oil emulsion fuel can also comprise 100 parts by weight of super-heavy oil, 30-80 parts by weight of water, 0.05-4 parts by weight of a nonionic surface active agent having an HLB of 9-19 and, optionally, 0.005-4 parts by weight of an anionic surface active agent.
Abstract:
A polymer or copolymer of maleic acid is produced by neutralizing (I) maleic acid in an aqueous medium with (III) an alkali metal hydroxide or ammonia at a molar ratio of (I) to (III) in the range of 100:0 to 100:90, polymerizing (I) with a polymerization initiator, adding (III) a further amount of the alkali metal hydroxide or ammonia at a molar ratio of (I) to (III) in the range of 100:100 to 100:130 in total through the previous addition and this addition and continuing the polymerization to the complete effect.
Abstract:
A polymaleate having an average molecular weight of 300 to 5000 is obtained by polymerizing a monoalkali metal maleate or monoammonium maleate at 80 DEG to 180 DEG C. in the presence of a polymerization initiator in an aqueous solvent.
