20120308628 | COATED POWDER AND COSMETIC PREPARATION USING THE COATED POWDER - A coated powder is obtained by coating a powder to be treated, with a mixture, as a coating agent, which includes 60 wt % to 90 wt % of an extremely hardened plant fat and oil having a melting point of 50° C. or more and 10 wt % to 40 wt % of an ester oil agent derived from a plant fat and oil. The powder is coated with the coating agent preferably at a temperature higher than the melting point of the extremely hardened plant fat and oil by 10 to 20° C. The powder is coated with the coating agent in an amount of 1 wt % to 15 wt %, particularly preferably 3 wt % to 10 wt %. Further, cosmetic preparations can be obtained by using the coated powder as a part or an entire part of the cosmetic preparations. | 12-06-2012 |
20120148511 | COMPOSITION FOR COSMETICS HAVING UV SHIELDING EFFECT AND SEBUM SOLIDIFYING ABILITY, AND COSMETIC PREPARATIONS - A composition for cosmetics is provided, which has a UV shielding effect and which can produce a cosmetic having good dispersibility, an excellent UV shielding effect and excellent use feeling, cosmetic effect, long-lasting cosmetic performance. The cosmetic obtained by using the same is provided. The composition for cosmetics includes (A) microparticulate titanium dioxide, (B) one kind or two or more kinds of magnesium hydroxide and calcium hydroxide. The composition for cosmetics preferably contains further (C) a clay mineral. The compounding weight ratio among (A):(B):(C) is preferably 20 to 60:3 to 40:0 to 77. In addition, the composition for cosmetics is preferably one in which a mixed powder of (A), (B) and (C) is lipophilically treated. | 06-14-2012 |
20120027709 | LIPOPHILICALLY SURFACE-TREATED POWDER HAVING EASY DISPERSABILITY AND COSMETIC BLENDED WITH SUCH A POWDER - Provided is a surface-treated powder, in which a powder is treated with a surface-treating agent composed of a mixture A+B including A: an alkyl alkoxy silane of a general formula (1): (C | 02-02-2012 |
20110110995 | SURFACE-TREATED POWDER AND COSMETIC COMPRISING THE SAME - Provided is a surface-treated powder having excellent usability and adhesion to skin. The powder is coated with a surface-treating agent including (a) a fluorine-containing monomer of a general formula (I) and (b) an alkoxy group-containing monomer of a general formula (II). The powder is used for various cosmetics. | 05-12-2011 |
20090263660 | SURFACE-TREATED POWDER AND COSMETICS CONTAINING SAME - By coating the surface of a powder comprising a silicone resin and/or an organic powder with a specific hydrophilizing agent, such powder is hydrophilized. The hydrophilizing agent includes water-soluble polyoxyalkylene glycol derivatives. The organic powder is at least one selected from PMMA, nylon, polyester, polystyrene, cellulose, silicone elastomer powder, silicone rubber powder, benzoguanamine, styrenedivinylbenzene pinhole polymer, ethylene tetrafluoride, polyethylene powder, polypropylene powder, polyurethane powder, silk powder, metal soap powder, starch powder, N-acylated lysine, an organic pigment, and a composite of at least one of these organic powders described above with a metal oxide and/or a metal hydroxide. Such coated (treated) powder has extremely great dispersibility (ease of dispersion) and very good dispersion stability (long-term dispersion stability with lapse of time) in aqueous dispersion media, particularly under acidic and alkaline conditions, specifically at pH 3 through 13. Using the surface-treated powder, additionally, a dispersion with good dispersibility (ease of dispersion) and great dispersion stability, preferably for cosmetics can be provided. The use of the surface-treated powder, or the use of the dispersion can provide further a cosmetic excellent in dispersibility and dispersion stability and further in re-dispersibility and dispersion stability with lapse of time and smooth feeling as compared to the related art when selecting aqueous cosmetic as an agent form. | 10-22-2009 |
