AI Technical Summary
Conventional purification processes for C-glycoside derivatives in cosmetic applications are cumbersome, inefficient, and result in unsatisfactory yield and purity, particularly on an industrial scale, due to the formation of impurities like organic salts and unpleasant odors, which are difficult to remove and lead to increased wastewater and reduced compatibility with other additives.
A process involving a purification step with a cationic ion exchange resin in an aqueous medium to convert impurities into less odorous forms, followed by separation, without the use of organic solvents, optimizing the purification process for industrial-scale production of high-purity C-glycoside derivatives.
The process significantly reduces impurities, including those causing unpleasant odors, improves yield, and minimizes environmental impact by reducing organic wastewater, making it easier to implement industrially and enhancing product quality.
