In European Union (EU) countries, the allowable content of PB in
cosmetic products is 0.4% for single ester and 0.8% for mixtures of all
parabens (Official Journal of the European Union, 2009). The governmental
units of the United States (Food and Drug Administration,
FDA) and Canada (Health Canada) have recommended the same
threshold for PB as that of EU. However, there is no legislation regulating
concentrations of parabens in cosmetics in any of those countries
