Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
113 words
A sunscreen composition comprising an extending medium and from about 1 to 20% by weight of the total composition of at least one vinylogous amide compound of the formula ##STR6## wherein R 1 is selected from alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, substituted aryl or alkaryl of from 1 to 18 carbon atoms; R 2 and R 3 may be the same or different and are selected from hydrogen, alkyl, alkenyl, cycloalkyl or cycloalkenyl of from 1 to 18 carbon atoms; R 4 and R 5 may be the same or different and are selected from hydrogen, alkyl, alkenyl, aryl and substituted aryl, alkaryl, cycloalkyl or cycloalkenyl of from 1 to 18 carbon atoms.
Claim 2
Dependent Claim
113 words
A sunscreen composition comprising an extending medium and from about 1 to 20% by weight of the total composition of at least one vinylogous amide compound of the formula ##STR6## wherein R 1 is selected from alkyl, cycloalkyl, alkenyl, cycloalkenyl, aryl, substituted aryl or alkaryl of from 1 to 18 carbon atoms; R 2 and R 3 may be the same or different and are selected from hydrogen, alkyl, alkenyl, cycloalkyl or cycloalkenyl of from 1 to 18 carbon atoms; R 4 and R 5 may be the same or different and are selected from hydrogen, alkyl, alkenyl, aryl and substituted aryl, alkaryl, cycloalkyl or cycloalkenyl of from 1 to 18 carbon atoms.
