PROBLEM TO BE SOLVED: To provide a method for producing dried powder oxygen-containing carotenoids, by using a protective colloid not exhibiting disadvantages of conventional technique. SOLUTION: This method for producing dried powder of one or several oxygen-containing carotenoids comprises (a) dispersing one or several kinds of oxygen-containing carotenoids into an aqueous molecular dispersion or a colloidal dispersion of protective colloid and (b) removing water and another solvent used, drying the oxygen-containing carotenoids in the presence or absence of a coating agent to convert the formed dispersion into the dried powder. In the method, at least one kind of a partially hydrolyzed soybean protein having a rate of hydrolysis larger than 5% is used as the protective colloid in the step (a).

PROBLEM TO BE SOLVED: To provide a product of an ultraviolet-protecting agent having effective action for protecting an organic material, especially the skin and/or the hair of a human from ultraviolet rays, and capable of being compounded readily in an aqueous system or a lipophilic system. SOLUTION: An aqueous dispersion of a scarcely water-soluble or water- insoluble organic UV-filter material containing at least one kind of scarcely water-soluble or water-insoluble organic UV-filter material as an amorphous or partially amorphous colloidal dispersion phase.
Abstract:
PROBLEM TO BE SOLVED: To provide a finely powdered carotenoid preparation controllable to have intended coloration effects and having a high bioavailability. SOLUTION: The production process comprises forming a molecular dispersion of carotenoid at an elevated temperature in a water-miscible volatile organic solvent optionally together with an emulsifier and/or an edible oil and adding a protective colloid to the solution. In this process, the hydrophilic solvent component is transferred to the water phase to form a hydrophobic phase of carotenoid as a nano-disperse phase and the obtained hydrosol is heat-treated at 40-90 deg.C. Then the solvent and water are removed from the heat-treated hydrosol to convert it into a water-dispersible dry powder.
Abstract:
The invention relates to pulverulent phytosterol formulations, methods for the production and use thereof. The aim of said invention is to deliver the phytosterol formulations incorporatable in aqueous and oily preparations. For this purpose, said pulverulent phytosterol formulations contain at least one type of phytosterol whose mean particle size ranges from 0.01 and 100 mu m, preferably from 0.01 to 10 mu m, better from 0.01 and 2 mu m and ideally from 0.05 and 1 mu m. Said phytosterol formulations are characterised, in particular in that at least one type of phytosterol is used in a semi-amorphous form. In a preferred embodiment, said phytosterol formulations are characterised in that said phytosterol is embedded in a protective colloid matrix.
Abstract:
The invention relates to a method for producing dry powders of one or several carotenoids, said method being characterised in that a) one or several carotenoids are suspended in an aqueous molecularly dispersed or colloidally dispersed solution of a mixture consisting of trehalose and at least one protein-containing protective colloid and b) the obtained suspension is transformed into a dry powder by separation of water and, optionally, additionally used solvents and by subsequent drying, optionally in the presence of a coating material.
Abstract:
The invention relates to a method for producing multi-layered surface structures, particles or fibres. Said method comprises the following steps: the reactive polycarboxylic acid or a derivative thereof is applied to a flat, particle or fibre-shaped support material which already contains the groups which can react with polycarboxylic acid or a derivative thereof, in order to form a covalent connection or is initially provided with said groups; (b) the carrier material treated in step a is, optionally, heated to between 60 °C to 130 °C, preferably to 80 °C to 120 °C due to acceleration, completion or additional optimisation of the covalent connections; (c) cellulose is applied to the carrier material which can form a covalent connection with the polycarboxylic acid or the derivatives thereof. The invention also relates to the use of the inventive method for producing multi-layered surface structures, particles or fibres for hydrophilizing surfaces, in particular for promoting adhesion between hydrophobic and hydrophilic materials and to improve the washability of synthetic fibres. The surfaces which are hydrophilizied by said method form the flat, particle or fibre-shaped carrier material.
