METAL HYDROXIDE COMPLEX CONTAINING MODIFIED MULTILAYER HYDROXIDE STRUCTURE CONTAINING ACTIVE INGREDIENT, AND METHOD FOR PRODUCTION THEREOF Russian patent published in 2024 - IPC C01B13/36 A61K8/02 A61K8/19 

FIELD: chemical or physical processes.

SUBSTANCE: invention relates to a metal hydroxide complex containing a multilayer hydroxide structure, which contains a base layer, a surface layer and an active ingredient, and to a method for production thereof. Metal hydroxide complex contains a multilayer hydroxide structure of chemical formula {[M_x(OH)_z]^B[M_y(OH)_w]^S}{(Aⁿ)_q}·m(H₂O), where [M_x(OH)_z]^B is base layer of multilayer hydroxide structure and [M_y(OH)_w]^S is surface layer of a multilayer hydroxide structure, M is Zn²⁺, A is an active ingredient, is an anionic compound, containing ascorbic acid as a functional group. Metal hydroxide complex includes an asymmetric laminated structure. Metal hydroxide complex is obtained by co-precipitation of an active ingredient and a precursor of the metal hydroxide structure in a precipitation reaction using alcohol and water.

EFFECT: possibility of maximizing the effect of the active ingredient.
