description	Composition comprising at least one polyhydroxy- alkanoate (PHA) and at least one calcium phosphate, said at least one calcium phosphate being in the form of aggregates having an average size ranging from 0.1 μm to 10 μm, preferably from 0.2 μm to 5 μm, and preparation processes thereof. Said composition can be used in particular in formulations for cosmetic use, wherein it can act not only as a biodegradable polymeric component which lasts for a long time on the surface of the keratins of skin and hair even after prolonged rinses, but also as an innovative carrier and dispenser of specific active ingredients, whose bioactivity is prolonged after each application. L'invention concerne une composition contenant au moins un polyhydroxy-alcanoate (PHA) et au moins un phosphate de calcium, ledit phosphate de calcium au moins se présentant sous la forme d'agrégats dotés d'une taille moyenne comprise entre 0,1 µm et 10 µm, de préférence entre 0,2 µm et 5 µm, ainsi que des procédés de préparation de cette composition. La composition selon l'invention peut être utilisée en particulier dans des formulations à usage cosmétique, la composition pouvant agir non seulement comme composant polymère biodégradable qui persiste longtemps sur la surface des kératines de la peau et des cheveux, même après des rinçages prolongés, mais également comme excipient innovant et distributeur de principes actifs spécifiques dont la bioactivité est prolongée après chaque application.
