1. In pharmaceuticals industry, hydroxypropyl-beta-cyclodextrin can increase solubility and bioavailability of insoluble drugs, so that the efficacy of drugs can last longer with less ingestion of drugs. It can adjust and control drugs release ratio, decrease side effects of drugs, and enhance stability of drugs. Hydroxypropyl-beta-cyclodextrin can be used for oral medication, injection, mucosal delivery systems (including the nasal mucosa, rectum, cornea, etc.), dermal drug delivery systems, lipophilic drugs targeting delivery, and also used as protective agent and stabilizer of protein.
2. In food and perfume industry, Hydroxypropyl-beta-cyclodextrin can enhance the stability of nutritional constituent and extend active time of effective constituent. Hydroxypropyl-beta-cyclodextrin can cover up bad smell and bad taste of nutritional constituent. It also can improve production processes and product quality.
3. In cosmetics industry, Hydroxypropyl-beta-cyclodextrin can reduce stimulate of organic molecular in cosmetic to the skin and mucosa. Hydroxypropyl-beta-cyclodextrin can enhance the stability of matter, by preventing oxidation and volatilization of nutrients.
