Your needs: reliable analysis of parabens in your products and formulations
Parabens: what are we talking about?
A paraben is an alkyl parahydroxybenzoate, which is an ester resulting from the condensation of parahydroxybenzoic acid with an alcohol. Its antibacterial and antifungal properties make it commonly used as a preservative in cosmetics, pharmaceuticals and foods.
The parabens used in the industry are :
- methylparaben or methyl 4-hydroxybenzoate (E218) and its sodium salt (E219);
- ethylparaben or ethyl 4-hydroxybenzoate (E214) and its sodium salt (E215);
- propylparaben or propyl 4-hydroxybenzoate (E216) and its sodium salt (E217);
- isopropylparaben ;
- butylparaben (en) ;
- isobutylparaben ;
- benzylparaben.
How to analyze parabens?
Parabens can be analyzed quantitatively by liquid chromatography coupled to a UV detector or diode array, or, if necessary for the analysis of traces of methylisothiazolinone, by mass spectrometry (LC-MS or LC-MSMS).
Regular controls allow to avoid production incidents and to be always in line with the evolution of the specifications.
