  • Patent number: 4545984
    Abstract: The invention concerns cosmetic agents containing compounds of the general formula (I) ##STR1## in which R.sup.1, R.sup.2 and R.sup.3 represent independently of one another a hydrogen atom, an intermediate alkyl group with 3 to 10 carbon atoms, a halogen atom, preferably a chlorine atom, a hydroxy group, an aryl group, an alkoxy group with 1 to 20 carbon atoms, substituted, if needed, with aryl, hydroxy, amino, alkoxy as well as aryloxy groups, or a carboxyl group esterified with an intermediate-chain alkyl group with 2 to 12 carbon atoms or with an aralkyl group, or two of the radicals R.sup.1 --R.sup.3 represent a naphthalene ring together with the benzene ring, and Y stands for an alkoxy group with 1 to 12 carbon atoms or an aralkoxy group. The compounds are used in amounts of 0.01 to 20, preferably 1 to 10, percent by weight, calculated with regard to the total preparation.

    Abstract: A topical cosmetic preparation for the treatment of seborrhea containing an antiseborrheically effective amount of at least one compound having the formula ##STR1## wherein Ar represents a member selected from the group consisting of phenyl, phenyl substituted with at least one group selected from the group consisting of alkyl having from 1 to 4 carbon atoms, alkoxy having from 1 to 4 carbon atoms, hydroxy and halo, naphthyl and heteroaromatic radical having from 4 to 5 carbon atoms in the cycle, and R represents a member selected from the group consisting of hydrogen, alkyl having from 1 to 4 carbon atoms, alkanoyl having from 1 to 4 carbon atoms, aryl and arylcarbonyl, where aryl has the same meaning as Ar, as an antiseborrheic, and further containing conventional vehicles and additives. The invention also relates to the process for reducing sebaceous cell sebum production employing said topical cosmetic preparation.
