Abstract: The invention relates to a compound (1) comprising at least 50% by weight of a functional agent, characterized in that it also comprises a waxy matrix (3), within which said functional agent is dispersed, wherein said compound (1) is solid at room temperature and intended to be dispersed by fluidization and/or solubilization within a cosmetic and/or dermatological composition to incorporate therein said functional agent, said functional agent being formed from solid particles (2) having undergone a surface treatment resulting in a reductions in the absorption capacity of the waxy matrix (3) by said treated solid particles (2), as compared to untreated solid particles of the same nature. The invention also relates to a formulation of cosmetic and/or dermatological compositions.

Abstract: The invention relates to a compound (1) comprising at least 50% by weight of a functional agent, characterized in that it also comprises a waxy matrix (3) having at least one organosilicon material, which organosilicon material forms the greater part by weight of said waxy matrix (3) and preferable the entirety thereof, within which said functional agent, formed by solid particles (3), is dispersed. Said compound (1) is solid at room temperature and intended to be dispersed by fluidization and/or solubilization within a cosmetic and/or dermatological composition of integrating said functional agent therein. The invention also relates to the formulation of cosmetic and/or dermatological compositions.

Abstract: For the cosmetic field, omniphobic cosmetic pigments under the form of a core shell structure: the core is or includes of a metal oxide on which is adsorbed poly(?-(1?4)-D-glucosamine) chains; the chains being acetylated, or partially or totally deacetylated. Also, the process for manufacturing the omniphobic cosmetic pigments, including: (i) preparing an acidic aqueous solution including metal oxide particles and a poly (?-(1?4)-D-glucosamine), the poly (?-(1?4)-D-glucosamine) being acetylated, or partially or totally deacetylated; and (ii) increasing the pH until 12, of the solution obtained at step (i) in order to obtain the adsorption of said poly (?-(1?4)-D-glucosamine on the metal oxide particles and the precipitation of the resulting metal oxide particles coated with the poly (?-(1?4)-D-glucosamine.
