Description

High Performance Liquid Chromatography (HPLC) Method for Analysis of EDTA, Oxymetazoline and Benzyl Alcohol

Benzyl alcohol is found in over-the-counter medications, topical creams, lotions, shampoos, and facial cleansers as an antibacterial, preservative, and/or fungicide. Benzyl alcohol is a colorless liquid with a mild pleasant aromatic scent. Benzyl alcohol is found in many essential oils including jasmine, hyacinth, neroli, rose, and ylang-ylang. Oxymetazoline is a decongestant that shrinks blood vessels in the nasal passages. All active compounds of nasal spray can be separated in HPLC on a Newcrom BH mixed-mode column. The analytical method uses acetonitrile (ACN) gradient and water with sulfuric acid (H2SO4) as buffer and UV detected at 260nm.
