Abstract
Novel pyrimidine N-oxide compounds and salts thereof, well suited for stimulating the growth of keratin fibers (e.g., the hair or the eyelashes) and/or limiting the loss thereof and/or increasing their density, have the formula (A): in which n is an integer ranging from 2 to 12; Ris a linear or branched, saturated or unsaturated alkyl radical, optionally substituted with a group —OR', —NR′R″ or —COOR′, Rhaving from 1 to 20 carbon atoms, or is NR′R″; Ris hydrogen, —NRR, —OR, or —SR, wherein Rand R, which may be identical or different, are each a linear or branched, saturated or unsaturated alkyl radical, optionally substituted with a group —OR′, —NR′R″ or —COOR′, Rhaving from 1 to 20 carbon atoms, with the proviso that Rand Rmay form part of a saturated or unsaturated ring member of 4 to 7 atoms, optionally containing at least one hetero atom; and R′ and R″, which may be identical or different, are each hydrogen or a saturated, linear or branched C-Calkyl radical.
