Simultaneous Analysis of Phenoxyethanol and Parabens

Simultaneous Analysis of Phenoxyethanol and Parabens


Paraben is a generic term for p-hydroxybenzoate esters. Due to their low toxicity in the human body, as well as antiseptic and mold proofing effects, parabens are used as preservatives in medicines, cosmetics, and foods. Phenoxyethanol is another component used as a germicide and antiseptic in cosmetics. It is a naturally-occurring compound that is found in substances such as green tea.

Phenoxyethanol is often used in combination with parabens in cosmetics to reduce the added paraben content. In this presentation, we will introduce and examine the simultaneous analysis of phenoxyethanol and parabens.
