• Description: Dexpanthenol belongs to a derivative of pantothenic acid (vitamin B5). It can penetrate the skin and mucous membrane to be quickly oxidized to pantothenic acid. The later one is extremely hygroscopic and binds water effectively. Therefore, Dexpanthenol can be used as a moisturizer. It is added to pharmaceutical and cosmetic products to relieve itching and improve wound healing. In ointments, it can be used for the treatment of sunburns, mild burns, minor skin injuries and disorders. It is also immediately applied after major abdominal surgery to minimize the possibility of paralytic ileus. In addition, it can also be supplemented into the commercial shampoos and hair conditioners to lubricate the hair shaft and give the hair a shiny appearance. The exact mechanism of action of Dexpanthenol is still unclear, perhaps through its enhancing effect on acetylcholine.
• Uses: Dexpanthenol may be used as an analytical reference standard for the determination of the analyte in pharmaceutical formulations by various chromatography techniques as well as partial least-squares multivariate calibration. D-Panthenol is an analogue of pantothenic acid (P190300), a member of the B complex vitamins. D-Panthenol is the biologically active enantiomer of Panthenol. immunosuppressant, mitoxantrone analogue less toxic on cardiac tissue antineoplastic
• Therapeutic Function: Gastrointestinal drug
