Commenting on the results the team concluded that, "PLA nanoencapsulation is a suitable strategy to improve the stability of OMC without reducing its protective power." In addition, the researchers found that including the PLA-encapsulated OMC into formulations did not affect their storage properties. Formulations containing the free OMC behaved no different than those containing the coated ingredient after being stored for six months at room temperature.

Extension to include UVA radiation
The team's current research investigates only the effect of the nanoencapsulation on OCM, which is a commonly used UVB filter, but research is underway to examine the effect the same technique may have on UVA filters.

Furthermore, research needs to be done to identify the positive effects that encapsulating may have on UVA and UVB filters when combined, in order to fully capitalize on the potential of this technology to protect against the entire spectrum of UV damage.
