NOVEL ORGANOGEL PARTICLES, METHOD FOR THE PREPARATION THEREOF AND COSMETIC USES THEREOF

摘要

The present invention relates to nanospheres of organogel comprising a low-molecular-weight organogelling agent capable of gelling a cosmetic or pharmaceutical active ingredient which is lipophilic or amphiphilic, non-volatile and liquid at ambient temperature. The low-molecular-weight organogelling agent is in particular 12-hydroxystearic acid. The invention also relates to a method for preparing aqueous dispersions of organogel nanospheres comprising, in particular, a step of hot emulsification or micro emulsification of an organogel, followed by cooling to ambient temperature. The invention also relates to the nanospheres and the aqueous dispersions of nanospheres obtained by the method according to the invention, and to the cosmetic or pharmaceutical compositions comprising them.
