METAL OXIDE SOLID SOLUTION CERIUM OXIDE/HYDROXIDE, AND RESIN COMPOSITION OR COSMETIC BLENDED THEREWITH |
| 摘要 |
PROBLEM TO BE SOLVED: To provide white metal oxide solid solution cerium oxide/hydroxide which has high ultraviolet ray shielding effects is white and further has transparency and reduced catalytic activity. SOLUTION: The metal oxide solid solution cerium oxide/hydroxide has a chemical structure satisfying Ce<SP>4+</SP><SB>1-X/4-Y</SB>M<SP>n+</SP><SB>Y</SB>(lattice defect)x/<SB>4</SB>O<SB>2-X-(4-n)Y/2</SB>(OH)<SB>X</SB>(wherein, Ce<SP>4+</SP>is tetravalent cerium ions; M<SP>n+</SP>is metal ions having an ion radius larger than that of tetravalent cerium ions and/or metal ions having a valency lower than that of tetravalent cerium ions; 0<X≤0.5; 0<Y<1; and n is the ionic valency of metal ions allowed to enter into solid solution). The substance is capable of exhibiting ultraviolet ray shielding by being blended into a resin composition or a cosmetic without changing their color tones. COPYRIGHT: (C)2005,JPO&NCIPI
