Essential Oils as Preservatives in Cosmetics: An Integrative Review: OAJBS Publishers
Essential Oils as Preservatives in Cosmetics: An Integrative Review by Asia Filatov* in Open Access Journal of Biomedical Science (OAJBS)
Cosmetics
are more natural and sustainable due to pressure from the current society,
which requires modification in traditional components, usually synthetic.
Preservatives, which aim to extend products due to their ability to inhibit the
growth and proliferation of microorganisms, are at the forefront of this
change. The present study is characterized as an integrative review carried out
about the use of essential oils (EO) as a cosmetic preservative, evaluating its
effectiveness to replace or complement the current preservative system. The
research’s guiding question was: EOs are effective as cosmetic preservatives
and substitute equivalents for synthetic ones? Twenty-eight articles were
selected in the consulted databases (Google Scholar, PubMed, and Scielo). EOs
are promising natural preservatives either alone or combined with other EOs and
with synthetic preservatives and additives. The results in vitro and cosmetic
formulations demonstrated antimicrobial action in a broad spectrum of
microorganisms. However, there is no standardization of the methods used to
assess the antimicrobial efficacy and few studies with continuity, being
necessary to carry out more studies concerning the preservative activity in
ready-made cosmetic formulations and in vivo studies with humans using the
final product for comparison and, in the future, replacement of synthetic
preservatives by the OE.
