<p><P>PROBLEM TO BE SOLVED: To provide a skin care external preparation for sunscreen having excellent compatibility with skin and spreadability thereto, and having suppressed squeaky feeling or coated feeling, and also excellent in water resistance and long-term stability. <P>SOLUTION: The skin care external preparation for sunscreen contains following components (A) and (B): (A) a fluorine-modified silicone resin containing (a) R<SP POS="POST">1</SP>SiO<SB POS="POST">1.5</SB>unit, (b) R<SP POS="POST">2</SP><SB POS="POST">3</SB>SiO<SB POS="POST">0.5</SB>unit and (c) (R<SP POS="POST">f</SP>-R<SP POS="POST">3</SP>)R<SP POS="POST">2</SP><SB POS="POST">2</SB>SiO<SB POS="POST">0.5</SB>unit (R<SP POS="POST">1</SP>and R<SP POS="POST">2</SP>respectively independently show an unsubstituted monovalent hydrocarbon group; R<SP POS="POST">3</SP>shows 2C-6C divalent alkylene group; and R<SP POS="POST">f</SP>shows 1C-8C perfluoroalkyl group. Further, the mole ratio of (a) unit/((b) unit+(c) unit) is 2-20, and the mole ratio of (b) unit/(c) unit is 2/3 to 20); and (B) an ultraviolet absorbing agent having absorption on UVA region. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
