Title (EN) ACTIVE AGENT-CONTAINING MICROCAPSULES
(FR) MICROCAPSULES CONTENANT UN AGENT ACTIF
Abstract:
(EN) Multi-layer microcapsules comprising a core comprising one or more active agents and two or more shells comprised of a wall-forming polymeric material, an opaque substance and a fatty acid salt, which are rupturable upon rubbing or pressing on the skin, are disclosed. The microcapsules are characterized by improved lightness values (L*) and/or compatibility in aqueous solution-containing formulations. Cosmetic or cosmeceutic formulations comprising the microcapsules, which can be, for example, body skin care formulation or facial skin care formulations, are also provided.
(FR) L'invention concerne des microcapsules multicouches, comprenant un noyau comportant un ou plusieurs agents actifs et deux ou plusieurs enveloppes constituées d'un matériau polymère de formation de paroi, d'une substance opaque et d'un sel d'acide gras, qui sont susceptibles de se rompre lors d'un frottement ou d'une pression sur la peau. Les microcapsules sont caractérisées par des valeurs de clarté améliorées (L*) et/ou la compatibilité de formulations contenant une solution aqueuse. L'invention concerne également des formulations cosmétiques ou cosméceutiques comprenant les microcapsules, qui peuvent être, par exemple, une formulation de soins de peau du corps ou des formulations de soins de peau du visage.
