New study says nanoparticles don’t penetrate the skin

skin1Research by scientists at the University of Bath is challenging claims that nanoparticles in medicated and cosmetic creams are able to transport and deliver active ingredients deep inside the skin.

Nanoparticles, which are tiny particles that are less than one hundredth of the thickness of a human hair, are used in sunscreens and some cosmetic and pharmaceutical creams.
The Bath study discovered that even the tiniest of nanoparticles did not penetrate the skin’s surface.

Metal Oxide Nanoparticles Toxicity Summary

hinamoxConsortium of Scientists from the European project HINAMOX ending in September 2012, targeted on the study of the safety of nanoparticles delivered excellent and surprising results.

Within the last three years the extensive work of 7 groups across Europe (all of them members of the European Nanosafety Cluster) as well as from Mexico and China was targeted on the thorough in vitro and in vivo study of possible adverse effects caused by metal oxide nanoparticles. Cell proliferation, cytotoxicity, immune response, genotoxicity, dust formation experiments as well as intravenous, nasal, oral and topical administrations of five types of nanomaterials – oxides of aluminium, cerium, iron, titanium and zinc – were studied.

All materials - with exception of ZnO nanoparticles - showed
