JP5519114B2 - Solid powder cosmetic - Google Patents

Description

  The present invention relates to a solid powder cosmetic, and more specifically, by blending a specific oily component, etc., it is excellent in use feeling such as smoothness during use, feeling of adhesion to skin, wet feeling, etc. The present invention relates to a solid powder cosmetic having good functionality such as holding property and good impact resistance of a molded product.

  Solid powder cosmetics such as powder foundation, pressed powder, and powder eye shadow can be molded by mixing powder and oil components, then filling the container and compressing and solidifying, and powder, oil components and solvent. There are known two methods, a wet molding method, in which the mixture is mixed, filled in a container, and then solidified by removing the solvent. Recently, due to its good filling moldability, it is possible to blend a large amount of spherical powder, flaky powder, and glitter powder, and in addition to the touch surface such as stretch and smoothness, the appearance quality of high brightness is high. For reasons such as being obtained, the number of cases using a wet molding method is increasing. (For example, Patent Documents 1 to 3)

  However, when a non-aqueous solvent is used, part of the oil component dissolves in the solvent and disappears together with the solvent during suction removal, or locally on the surface of the molded product due to capillary action as the solvent dries. There was a problem of being materialized. In addition, when water or water-based solvents are used, oil agent components insoluble in these solvents aggregate together with the powder, reducing the strength of the molded product and the dispersibility of the powder, resulting in a non-uniform feel. There was a problem.

It is preferable to manufacture by filling and molding and removing water by drying. At this time, a mixture of the oil-in-water emulsion and the component (e) powder may be a slurry. In that case, the mixing amount of the oil-in-water emulsion varies depending on the composition of the powder and the amount of the oil agent, but is prepared so as to have a viscosity that allows easy extraction of air from the slurry and filling into a container or the like. The oil-in-water emulsion is preferably 50 to 250 parts with respect to 100 parts of the powder. If the amount of the oil-in-water emulsion is too large, drying takes a long time, cracking after drying, loss of contents, and impact resistance are also reduced. Thus, after filling a container etc., water is removed and it solidifies. Water is removed by a conventional method such as natural drying, warm drying, warm air drying, or the like.

  In the solid powder cosmetic of the present invention, cosmetic ingredients, perfumes, preservatives, ultraviolet absorbers, antioxidants, and the like can be blended as necessary within a range that does not interfere with the effects of the present invention.

  The solid powder cosmetic of the present invention can be applied as a skin care cosmetic such as eye color, foundation, cheek red, eyeliner, face powder, eyebrow, lipstick and other makeup cosmetics, body powder and antiperspirant powder.

  Hereinafter, although an example is given and explained in detail, the present invention is not limited to these.
