Composition for caring for the hair or the eyelashes, containing a pyrazolecarboxamide compound, use thereof for stimulating the growth of the hair and the eyelashes and/or for reducing their loss

摘要

The invention relates to a composition for caring for or making up the hair or the eyelashes, which is intended to limit their loss and/or to increase their density, and containing a pyrazole compound of formula (I), or a salt thereof: chemistry chemdraw filechemistry mol file;in which: ;R₁ and R₂ represent H; an optionally substituted C₁-C₂₀ alkyl; or at least one ring optionally containing at least one hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function, and possibly being substituted; ;R₃ and R₅ represent H, a halogen, OR₆, SR₆, NR₆R′₆, CN, CF₃, COR₆, CSR₆, COOR₆, COSR₆, CSOR₆, CSSR₆, NR₆COR′₆, NR₆CSR′₆, OCOR₆, SCOR₆, CSNR₆R′₆, SO₂R₆, SO₂NR₆R′₆, NR₆SO₂R′₆, NR₆C(═NR′₆)NR″₆R′″₆, SiR₆R′₆R″₆, A or at least one ring optionally containing at least one hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function and possibly being substituted; ;R₄ represents H, A, COR₆, CSR₆, COOR₆, CONR₆R′₆, CSNR₆R′₆, SO₂R₆, SO₂NR₆R′₆ or at least one ring optionally containing a hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function, and possibly being substituted; ;R₆, R′₆, R″₆ and R′″₆ represent H; an optionally substituted C₁-C₂₀ alkyl; at least one ring optionally containing at least one hetero atom, these rings possibly being fused, comprising a carbonyl or thiocarbonyl function, and possibly being substituted with at least one substituent R; ;A represents an optionally substituted C₁-C₂₀ alkyl.
