AI Technical Summary
In existing technologies, niacinamide has poor stability, succinic acid has a short retention time on the skin surface and is difficult to exert a long-lasting soothing or oil-controlling effect, and there are no reports on technical solutions for succinic acid and niacinamide to form specific crystal form supramolecular cocrystals.
Succinic acid-nicotinamide cocrystal was prepared using supramolecular cocrystal technology. A specific molar ratio and solvent system were used, combined with gradient cooling crystallization and vacuum drying, to form a stable triclinic cocrystal structure, which enhances the stability of nicotinamide and the skin residue effect of succinic acid.
The prepared succinic acid-niacinamide cocrystal improves the stability of niacinamide and its residual effect on the skin surface, significantly improving its whitening and oil-controlling effects, and is suitable for personal care products, cosmetics and skin care products.
