Undecylenoyl peg-5 paraben is a chemical compound belonging to the paraben family.

Significant substances used in the production method:
Poly(oxy-1,2-ethanediyl), .alpha.-(1-oxo-10-undecenyl)-.omega.-(4-carboxyphenoxy)-, .alpha.hydro-.omega.-hydroxypoly(oxy-1,2-ethanediyl) esters Centrifugation, washed, dried.

Safety
Parabens are preservative chemical compounds that have been the subject of attention in the scientific literature as possible endocrine disruptors (particularly propylparaben and butylparaben), i.e. with the possibility of damaging the hormone-producing glands in our bodies, particularly in the breasts. The 2004 study by Darbre et al. showed that parabens remain in our bodies as intact esters (2). Following this study, some of the scientific literature in 2005 and 2006 cast doubt on Darbre's conclusions and claimed they were limited. However, both the US FDA and the European SCCP authorised in 2006 the use of a single paraben in cosmetic products at a concentration of 0.4% and the use of total parabens at a concentration of 0.8%. However, there is no shortage of studies that consider the restrictions unnecessary: M. G. Kirchhof et al. in 2013 found that parabens are among the safest and most well-tolerated preservatives and that current data do not support drastic regulations or personal exposure restrictions. Darbre in 2014 published a further study in which he showed how parabens can cause DNA damage.

What it is used for and where
