权利人:CHEMCOM SA
摘要:The present invention relates to a lightening composition comprising a lightening effective amount of a compound of formula (I), or a tautomer, a stereoisomer, a hydrate, a solvate, a salt, or a polymorph thereof, wherein R1, R2, R3, R4, R5, R6, R7, m and n are as defined in the description and claims. The present invention also relates to a compound of formula (I2) or a tautomer, a stereoisomer, a hydrate, a solvate, a salt, or a polymorph thereof, wherein R1, R2, R3, R4, R5, R6, and R7 are as defined in the description and claims. The present invention also relates to the use of at least one compound of formula (I) or any subgroup thereof, or mixtures thereof, as depigmenting agent. The present invention also relates to the use of at least one compound of formula (I) or any subgroup thereof, or the use of the lightening composition, for preventing and/or reducing pigmentation of normal skin. The present invention also relates to the use of at least one compound, or the use of the lightening composition according to the first aspect, for decreasing the amount of melanin in melanocytes, for decreasing melanin synthesis, for impairing melanin transport and/or for impairing the distribution of melanin in suprabasal layers.
