HPLC Method for Chlorphenesin, 2-Phenoxyethanol, EDTA (Ethylenediaminetetraacetic Acid) on Newcrom BH by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Chlorphenesin, 2-Phenoxyethanol, EDTA (Ethylenediaminetetraacetic Acid).
Ethylenediaminetetraacetic acid (EDTA) is a synthetic amino acid with the chemical formula C10H16N2O8. It is typically used in industry to sequester metal ions, which helps prevent change of colors in textiles and uneven bleaching in paper. Due to it being a chelator, it is also used to soften water during laundry, remove hydrogen sulfide from gas streams, as well as treat mercury and lead poisoning.
Phenoxyethanol is a synthetic compound with the chemical formula C8H10O2. It is said to have antimicrobial and preservative properties, leading to wide use of it in cosmetics, medicine, and biocides. It is considered safe in the US and Europe at limited concentrations.
Chlorphenesin is a synthetic preservative with the chemical formula C9H11ClO3. It is often used in cosmetics, pharmaceuticals, and hygiene products. It’s preservative properties prevent yeast, fungi, and bacteria from growing in cosmetics as well as lead to it’s occasional use as an anti-fungal treatment. While it is approved for use in United State as the European Union at low concentration, it is banned in Japan. In higher concentrations it can cause nausea, vomiting, and even seizures.

Separation of 2-Phenoxyethanol on Newcrom R1 HPLC column
May 16, 2018
2-Phenoxyethanol can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
