Abstract: The layered double hydroxide is characterized by comprising base layers each comprising a metal double hydroxide represented by the formula: M(II)1-XM(III)X(OH)2 (wherein M(II) represents one or two bivalent metal atoms; M(III) represents a trivalent metal atom; and x represents 0.2 to 0.33), and an intermediate layer and interlayer water each intercalated between the base layers, wherein the intermediate layer comprises a compound represented by the formula: R1-COOH or R2-SO3H (wherein R1 and R2 independently represent at least one substituent selected from an aliphatic hydrocarbon group, a substituted aliphatic hydrocarbon group, an aromatic hydrocarbon group, a substituted aromatic hydrocarbon group, a heterocyclic group and a substituted heterocyclic group).

Abstract: Disclosed is a layered double hydroxide capable of delamination in water comprising a plurality of basal layers of a double hydroxide of Formula: M(II)1-xM(III)x(OH)2 wherein M(II) is Mg, Zn or a combination thereof, M(III) is Al, and x is 0.2 to 0.33 and a plurality of intercalated layers between each adjacent basal layers of Mg acetate, Zn acetate or Ce acetate and water of intercalation. A process for producing the layered double hydroxide is also disclosed. The layered double hydroxide find use as an vehicle component or an anti-corrosive pigment of water-based protective coatings for metallic substrates, and as a humectant or a stabilizing agent for cosmetic preparations such as lotions, creams or foundations.

Abstract: The disclosure describes a humectant, antistatic agent, film-forming agent or dispersant comprising an effective amount of a polysaccharide produced by two strains of Kliebsiella composed of D-glucuronic acid, L-rhamnose, D-galactose and D-glucose in a molar ratio of D-glucuronic acid:L-rhamnose:D-galactose:D-glucose=0.8-1.2:2.4-3.6:0.8-1.2:0.8-1.2.

Abstract: A polysaccharide having a molecular weight of about 5.times.10.sup.3 to 10.times.10.sup.6 as measured by gel permeation chromatography and composed of 5 saccharides, viz. D-glucose, D-galactose, D-glucuronic acid, D-ribose and D-riburonic acid, in a molar ratio of D-glucose:D-galactose:D-glucuronic acid:D-ribose:D-riburonic acid=10:1.8-2.9:1.8-2.6:0.5-1.7:0.5-1.7, with the content of o-acetyl groups in the polysaccharide being 0-10% by weight.

Abstract: Disclosed are novel polysaccharides having the following physicochemical properties: (1) a molecular weight determined by gel filtration chromatography is about 5.times.10.sup.3 to 10.times.10.sup.6, (2) the constituent glycoses are D-galacturonic acid, L-rhamnose and D-glucose, (3) the constituent glycoses are joined substantially by 1,3-linkages, and (4) a configuration of D-galacturonic acid is .alpha., that of L-rhamnose is .beta. and that of D-glucose is .alpha.. A process for producing polysaccharides composed of D-galacturonic acid, L-rhamnose and D-glucose, use of the polysaccharides and a strain for producing the polysaccharides are also disclosed.
