发明名称 NOVEL 2-BENZOXAZOLYL BENZENE DERIVATIVES AND THEIR USE AS UV SCREENING AGENTS
摘要 Methods for making UV screening compositions by combining benzoxazolyl benzene derivatives of formula (I): wherein R<SUP>1 </SUP>is hydrogen, C<SUB>1-20</SUB>-alkyl or C<SUB>2-20</SUB>-alkenyl; R<SUP>2 </SUP>and R<SUP>3 </SUP>are independently a group -C(R<SUP>4</SUP>,R<SUP>5</SUP>)C(R<SUP>6</SUP>)-C(R<SUP>7</SUP>,R<SUP>8</SUP>) (a) or a group -C(R<SUP>4'</SUP>,R<SUP>5'</SUP>)CH(R<SUP>6'</SUP>)CH(R<SUP>7'</SUP>,R<SUP>8'</SUP>) (b), wherein R<SUP>4</SUP>, R<SUP>5</SUP>, R<SUP>6</SUP>, R<SUP>7</SUP>, R<SUP>8</SUP>, R<SUP>4'</SUP>, R<SUP>5'</SUP>, R<SUP>6'</SUP>, R<SUP>7'</SUP> and R<SUP>8'</SUP> are independently, hydrogen, C<SUB>1-10</SUB>-alkyl or C<SUB>2-10</SUB>-alkenyl, or C<SUB>2-10</SUB>-alkyl or C<SUB>3-10</SUB>-alkenyl containing at least one oxygen atom interrupting the hydrocarbon chain; or wherein R<SUP>4</SUP>, R<SUP>5</SUP>, R<SUP>6</SUP>, R<SUP>4'</SUP>, R<SUP>5'</SUP> and R<SUP>6'</SUP> are hydrogen, C<SUB>1-10</SUB>-alkyl or C<SUB>2-10</SUB>-alkyl containing at least one oxygen atom interrupting the hydrocarbon chain, or alkyl substituted by silane or oligosiloxane moiety, and one of R<SUP>7 </SUP>and R<SUP>8 </SUP>or R<SUP>7'</SUP> and R<SUP>8'</SUP> is a silane or oligosiloxane moiety and the other one of R<SUP>7 </SUP>and R<SUP>8 </SUP>or R<SUP>7'</SUP> and R<SUP>8'</SUP> is hydrogen; and X is phenylene or naphthylene, or substituted phenylene or naphthylene with a cosmetic base. Methods of protecting a surface from UV radiation by applying a UV screening agent of formula I to a surface such as hair or skin.
