Latest Patents

Z Helena Qi holds a patent for the "Purification of chemically modified cyclodextrins." This patent describes a method for purifying chemically modified cyclodextrins, such as hydroxypropyl cyclodextrins, through treatment with activated carbon derived from coal or coconut shells. The process involves using an amount of activated carbon that ranges from 50% to 300% by weight of the modified cyclodextrin. This treatment effectively removes organic impurities, such as glycol, that are introduced during the chemical modification process. The purification can be achieved by passing an aqueous solution of the unpurified modified cyclodextrin through a column packed with activated carbon or by adding the activated carbon directly to the unpurified modified cyclodextrin and gently agitating the mixture.
