Directa Plus logoDirecta Plus has announced it has received positive test results confirming that its graphene nanoplatelets are not absorbed through human skin. The Company said this was the eighth in vitro test to show that there is no absorption potential for the Pure G+ powder.

The study was carried out by an independent third party and followed international standards, using human skin reconstructed in the lab. Directa Plus said successful results from in vitro tests of its hypoallergenic, non-toxic products are vital for their use in textile markets, where customers have to be certain of the safety of the apparel they produce and market.

Pure G+ was applied on the tissue surface for six and 24 hours and at the end of the experimental time, it was calculated how much Pure G+ graphene had penetrated through the skin.
