Abstract: An object is to provide an ultrasonic transmission efficiency improving composition for ultrasonic diagnosis which can suppress attenuation of ultrasonic waves in a skin stratum corneum to reach deeper portions of a living body, and has ultrasonic transmission efficiency stable even with temperature change during use; an ultrasonic diagnostic gel composition which is obtained by gelling the ultrasonic transmission efficiency improving composition into a gel state; and an imaging method using the ultrasonic transmission efficiency improving composition and the ultrasonic diagnostic gel composition.

Abstract: A cosmetic in an emulsified state, in which a titanium dioxide microparticle coated with hydrous silicic acid and/or a hydrous silicate compound, a higher alcohol, an oily component other than the higher alcohol, and a polysaccharide are contained, and the polysaccharide containing at least one of fucose, glucose, glucuronic acid and rhamnose as a constituent monosaccharide, and having fucose and/or rhamnose in a side chain is contained in an amount of 0.01% by weight to 1% by weight relative to the total amount of the cosmetic. And a cosmetic containing the higher alcohol, the oily component and the polysaccharide in an emulsified state, in which the higher alcohol is composed of two or more kinds of higher alcohols having different molecular weights, and is contained in the cosmetic in an amount of 1% by weight to 20% by weight relative to the total amount of the cosmetic.

Abstract: A cosmetic exhibiting improved thermal stability and storage stability, which is prepared by using a three-phase emulsification-dispersing method in an aqueous phase. In the cosmetic containing an oily base material and/or a pigment as a component to be emulsification-dispersed, an emulsification-dispersing agent and water, the thermal stability and storage stability are improved, and the emulsification-dispersing agent composed of a polysaccharide having a particulate structure as a main component, and two or more kinds of components to be emulsification-dispersed are contained. The components to be emulsification-dispersed exhibit a dielectric constant ranging from 1 to 5 (F/m), and an inorganicity/organicity ratio ranging from 0 to 0.5.

Abstract: An emulsion and dispersion system exhibiting excellent stability against heat and excellent stability over a long period time in interfaces between functional oily bases and water, or between functional granules as solid particles and water, etc., a cosmetic composition containing an emulsifying dispersant which is capable of performing emulsification and dispersion independently of required HLB values of the functional oily bases or the surface states of the functional granules, and a producing method of such a cosmetic composition. A cosmetic composition characterized in that an emulsifying dispersant including polysaccharides with particulate structure as a main component, and components to be emulsified are contained, and a producing method thereof.

Abstract: The present invention provides a polymer comprising a polysaccharide having excellent water absorption properties, moisture absorption properties, moisture retention properties and thickening properties. Said polysaccharide has the following properties: (A) the principal constituents of the sugar composition are rhamnose, fucose, glucose and glucuronic acid which are present in a molar ratio of (1-4):2:(1-8):(1-4); (B) elemental analysis (wt %):C: 36 .+-.3H: 7 .+-.1O: 56 .+-.4,containing 9-13% of crystalline water(C) solubility:slightly soluble in water; soluble in alkalies; insoluble in methanol, ethanol and acetone;(D) UV absorption spectrum:no absorption detected at 280 nm characteristic of proteins (peptides) or at 260 nm characteristic of nucleic acids; and(E) IR absorption spectrum:an absorption pattern characteristic of polysaccharides is observed near 800-1200.sup.-iSaid polysaccharide is produced by a fermentation method using a natural medium or a synthetic medium of Alcaligenes microorganism.

Abstract: A polysaccharide (Biopolymer B-16) being produced by cultivating Alcaligenes latus strain B-16 (FERM-2015) and having at least one function selected from water absorption, moisture absorption, humectant capability, thickening capability, suspension stability, emulsion stability and dispersant capability along with high biodegradability and which can be used without creating any environmental hazard such as secondary pollution, said Biopolymer B-16 consisting essentially of rhamnose, fucose, glucose, mannose and glucuronic acid which are present in a molar ratio of(1-10):(2-10):(4-20):(1):(1-5).
