An emulsifying dispersant includes, as the main component, vesicles formed from an amphiphilic substance capable of self-assembly or an emulsifying dispersant comprising single particles of a biopolymer as the main component. The particles made from amphiphilic substances capable of self-assembly are used. The amphiphilic substances are selected from among polyoxyethylene-hydrogenated castor oil derivatives wherein the average number of added ethylene oxide molecule is 5 to 15, dialkyldimethyl-ammonium halides wherein the chain length of the alkyl or alkenyl is 8 to 22, and phospholipids or phospholipid derivatives. According to the invention a three-phase structure composed of an aqueous phase, an emulsifying dispersant phase and an oil phase is formed on the surface of an emulsion to give an emulsion (such as emulsion fuel) excellent in thermal stability and long-term stability.

Emulsification dispersants, a method for emulsification and dispersion using the emulsification dispersants, emulsions, and emulsion fuels

The invention provides an emulsification technique which permits the formation of functional oil/water or functional granules/water emulsion systems excellent in thermal stability and long-term stability and which can attain the emulsification independent of required HLB of the functional oils, and the dispersion independent of surface properties of the functional granules. In the technique is used an emulsifying dispersant comprising, as the main component, vesicles formed from an amphiphilic substance capable of self-assembly or an emulsifying dispersant comprising single particles of a biopolymer as the main component. The particles made from amphiphilic substances capable of self-assembly are used. The amphiphilic substances are selected from among polyoxyethylene-hydrogenated castor oil derivatives represented by the general formula (1) wherein the average number of added ethylene oxide molecule is 5 to 15, dialkyldimethyl-ammonium halides wherein the chain length of the alkyl or alkenyl is 8 to 22, and phospholipids or phospholipid derivatives. According to the invention a three-phase structure composed of an aqueous phase, an emulsifying dispersant phase and an oil phase is formed on the surface of an emulsion to give an emulsion (such as emulsion fuel) excellent in thermal stability and long-term stability. 

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.
