Abstract
Abstract This invention relates to topical cosmetic preparations. More particularly, this invention relates to a topical cosmetic preparation for the treatment of oily hair and seborrheic skin which comprises an effective amount of at least one compound of the formula ##STR1## wherein R 1 , R 2 , and R 3 , any of which may be the same or different, each represent hydrogen, hydroxyl, or --OR 4 , where R 4 is an alkyl of from 1 to 6 carbon atoms or a substituted or unsubstituted benzyl, or two of the groups R 1 , R 2 , and R 3 represent methylenedioxy; X is a substituted or unsubstituted alkylene of from 1 to 3 carbon atoms; and Y is --COOH, --CN, --CONR 5 R 6 , or --COOR 7 , where R 5 and R 6 each represent hydrogen, alkyl of from 1 to 6 carbon atoms, or substituted or unsubstituted aryl, or aralkyl, or together with the nitrogen atom R 5 and R 6 represent a heterocycle, and R 7 is an alkyl of from 1 to 6 carbon atoms or a substituted or unsubstituted aralkyl.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
203 words
A process of treating oily hair and seborrheic skin which comprises administering to an individual in need of such treatment an effective amount of a topical cosmetic preparation comprising from about 0.01 to 20 percent by weight, based upon the weight of the total preparation, of at least one compound of the formula ##STR5## wherein R 1 , R 2 , and R 3 , any of which may be the same or different, each represent hydrogen, hydroxyl, or --OR 4 , where R 4 is an alkyl of from 1 to 6 carbon atoms or a benzyl, or two of the groups R 1 , R 2 , and R 3 represent methylenedioxy; X is an alkylene of from 1 to 3 carbon atoms; and Y is --COOH, --CONR 5 R 6 , or --COOR 7 , where R 5 and R 6 each represent hydrogen, alkyl of from 1 to 6 carbon atoms, or benzyl and R 7 is an alkyl of from 1 to 6 carbon atoms or a benzyl, where each of the benzyl and alkylene may have one or more non-interfering substituents selected from the group consisting of lower alkyl, halogen, nitro, lower alkanoyl, lower alkoxy, and methylenedioxy.
Claim 2
Dependent Claim
