Electrostatic and Hydrophobic Interactions in the System: Synthetic Food Dye Е133 – Cetylpyridinium Chloride – H2O

Investigated the conditions of formation and solubilization ion associate synthetic food dye «brilliant blue» (Е133) ions with cetylpyridinium chloride (TSPKH). The composition of the associate, the solubility in water and micelles TSPKH. The importance of such interactions in the photometric, potentiometric and other methods of determination of synthetic food dyes.
