MicNo has exhibited a higher visible light transparency than the current commercial nano ZnO particles. It is also able to cover a larger surface area per % mass; with its novel shape able to cover approximately 70% more surface area than the same amount of nano ZnO, assuming no agglomeration takes place. A low level of uncontrolled agglomeration is another advantage of MicNo over the commercially available versions of ZnO which exhibit uncontrolled agglomeration both in micron & nano forms. With the right formulation using MicNo it is possible to create an SPF 50 product with broad spectrum & transparent protection.
The novel & patented MicNo particle technology creates ZnO particles in the micron size range that do not easily penetrate the skin, unlike the smaller nano particles. This means that MicNo has a much lower toxicity level than nano ZnO, similar to micron ZnO.
Research has shown MicNo to be biocompatible & safe, with it presenting much less cytotoxicity, genotoxicity & phototoxicity when compared to commercial nano ZnO. MicNo also exhibited less phytotoxicity since, unlike nano ZnO, it does not accumulate in plant roots. This biocompatibility of MicNo makes it a much kinder sunscreen for the environment as it causes less pollution & damage to aquatic & plant life.
MicNo also has excellent antimicrobial properties, exhibiting broad spectrum antibacterial activity against a range of microorganisms & a number of fungi. This makes it easier to prepare formulations with less or no preservatives, a feature which is particularly appealing to manufactures due to this recent trend in cosmetic product formulations.
Considering the recent market trend for broad spectrum coverage, MicNo offers very high protection to high energy visible light & blue light. While SPF & protection against UV rays is the current main priority of sun protection products, high energy visible light is also known to cause aging effects so an additive which offers extra protection, can only be considered advantageous.
