Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
103 words
A sunscreen composition comprising an extending medium and 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 are 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 are 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; and Y is N.
Claim 2
Dependent Claim
103 words
A sunscreen composition comprising an extending medium and 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 are 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 are 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; and Y is N.
Claim 3
Dependent Claim
22 words
The composition of claim 1 wherein the vinylogous amide is present from about 1 to 20% by weight of the total composition.
Claim 4
Dependent Claim
15 words
The composition of claim 1 containing at least one vinylogous amide and in addition oxybenzone.
Claim 5
Dependent Claim
15 words
The composition of claim 1 containing at least one vinylogous amide and in addition 2-ethylhexyl-p-dimethylaminobenzoate.
Claim 6
Dependent Claim
13 words
The composition of claim 1 containing a vinylogous amide of the formula ##STR7##
Claim 7
Independent Claim
128 words
A method of protecting human skin from the erythmic effects of ultraviolet radiation which comprises applying to the skin a sunscreen composition containing from about 1 to 20% by weight of the total composition of at least one compound of the formula ##STR8## 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 are 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 are 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; and Y is N.
Claim 8
Independent Claim
128 words
A method of protecting human skin from the erythmic effects of ultraviolet radiation which comprises applying to the skin a sunscreen composition containing from about 1 to 20% by weight of the total composition of at least one compound of the formula ##STR8## 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 are 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 are 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; and Y is N.
