Description

  The present invention is an excellent novel dispersion composition that has high dispersion stability (long-term storage stability) and dispersibility when powder (particles) is blended with a specific oil, and has a stable function during cosmetic production. It is about things. More specifically, a specific organopolysiloxane, a powder and a specific oil agent, more specifically, the ratio IV / OV of the inorganic value (IV) to the organic value (OV) is at most 0.5 (0.5 or less). The present invention relates to a dispersion composition containing at least a certain oil agent, or a powder that has been surface-treated with a specific organopolysiloxane in advance and a specific oil agent, and a cosmetic blended with such a dispersion composition. .

  In the dispersion composition of the present invention, a specific organopolysiloxane is used as a surface for a specific oil agent, that is, an oil agent having an inorganic value (IV) to organic value (OV) ratio IV / OV of at most 0.5. Since the treated powder is dispersed, there is no sedimentation or aggregation over time, excellent dispersion stability (long-term storage stability), and excellent dispersibility. In addition, since such a powder can be blended at a high concentration, when blended into the final product, the function of the powder, which varies greatly depending on the dispersion state and amount of the powder (particles) used, for example, to the skin The adhesive strength (adhesiveness), feel (use feeling), gloss, hiding power, coloring power, transparency, ultraviolet and infrared shielding ability, fluorescence, luminescence, etc. can be dramatically improved.

  Therefore, by blending the dispersion composition of the present invention, the function as a cosmetic is greatly improved as compared with the conventional one, so that a cosmetic superior to the conventional one can be provided.

  Furthermore, the dispersion composition of the present invention can be applied not only to cosmetics but also to various fields such as plastic additives, inks, paints, toners (magnetic powders), chemical fibers, packaging materials, and electronic materials.

  Conventionally, when a dispersion composition is blended with a powder in an oil agent, it tends to settle into a hard cake due to the difference in specific gravity between the powder and the oil agent, and as a third component for preventing sedimentation and stabilizing the dispersion, etc. Many of them are blended with a dispersant or a gelling agent (see, for example, Patent Documents 1, 2, 3, and 4). However, a dispersion composition containing a dispersing agent such as a surfactant or a gelling agent may cause agglomeration of the powder or separation of the oil phase and the aqueous phase depending on the type of the oil or surfactant when formulated into the final product. The nature is low.

  On the other hand, many proposals have been made so far to uniformly disperse the powder in an oleophilic solvent (oil agent) (see, for example, Patent Document 5).

  For example, by incorporating lipophilic powder (lipophilic powder) coated with a solid surface treatment layer and a liquid surface treatment layer at room temperature into a lipophilic solvent, the dispersibility of the powder, etc. There is a report that an oily dispersion (dispersion composition) which is very excellent can be provided (see Patent Document 5). However, in the reported oil dispersions, the affinity between the lipophilic powder and the lipophilic solvent (oil agent) has been improved, but depending on the type of the surface treatment agent selected, Compatibility with oily solvent changes. That is, when the powder content in the oily solvent is defined by the type of the surface treatment agent selected and the powder content in the dispersion composition is small, depending on the type of the lipophilic solvent selected, the dispersion stability It is difficult to store for a long time in terms of storage of the dispersion (low long-term storage stability is poor). In order to solve these problems, it is possible to perform surface treatment of powder by selecting a surface treatment agent with good compatibility for each lipophilic solvent, but use it by replacing the surface treatment agent for each lipophilic solvent. There are many types of raw materials and products to handle, which is a disadvantage for the manufacturing side. Further, there arises a problem that the degree of freedom in designing the cosmetic product as the final product is reduced (the versatility is reduced). Accordingly, the compatibility between the powder and the lipophilic solvent, the dispersion stability in the lipophilic solvent (such as long-term storage stability), and the dispersibility are insufficient, and further improvements have been demanded. Further, a description of a powder in which the powder is dispersed at a very high concentration and uniformly in the oil agent (excellent in dispersibility) and the state is maintained for a long period (excellent in dispersibility and long-term storage stability). Is not found.

Another object of the present invention is to provide a cosmetic or the like that is more excellent in emulsion stability and usability than conventional products and that can fully exhibit the functions of powder.

  As a result of intensive studies to solve the above-described various problems, the present inventors have found that a specific oil agent, that is, an oil agent having an inorganic value (IV) to organic value (OV) ratio IV / OV of at most 0.5. In addition, a dispersion composition containing a specific organopolysiloxane and a powder is excellent in compatibility between the powder and the oil, and even when the target powder is blended at a high concentration, it is dispersed in the oil.
