Definitions
- the present disclosure relates to a liquid composition having a powder in a solvent and a method for producing the same.
- the present disclosure also relates to a cosmetic having the composition.
- Slurry products in which solid particles are dispersed in a solvent are used in a wide range of fields such as foods, paints, cosmetics, inks and ceramics.
- a technique for improving the dispersibility of particles has been developed (see, for example, Patent Document 1 and Non-Patent Document 1).
- the organic-inorganic composite particle dispersion described in Patent Document 1 is obtained by converting organic-inorganic composite particles into oils, waxes, hydrocarbons, fatty acids, alcohols, alkyl glyceryl ethers, esters, polyhydric alcohols, saccharides.
- the organic-inorganic composite particles are dispersed in a solvent selected from silicone oil, crosslinked silicone gel, and fluorine oil or a mixed solvent thereof in the range of 0.001 to 50% by weight.

- the polymer chain adsorbed on the particle surface is contracted in a coil shape.
- the above-mentioned slurry product is usually prepared so that the ratio of the solvent and the powder is optimal.
