Simultaneous Analysis of Phenoxyethanol and Parabens
Simultaneous Analysis of Phenoxyethanol and Parabens
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.
