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. The oily component is contained in an amount of 1% by weight to 20% by weight relative to the total amount of the cosmetic, and the polysaccharide is contained in an amount of 0.01% by weight to 1% by weight relative to the total amount of the cosmetic, and a producing method thereof.

Cosmetic and method for production thereof

Polysaccharide and a method of producing it

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

Polysaccharide, and water absorbent, moisture absorbent or humectant and
