Entekno Materials have designed & developed a novel Zinc Oxide (ZnO) form that is daily care using their patented MicNo® ZnO Particle Technology. The innovative MicNo® ZnO is a tailored, hexagonal platelet, micron sized particle. MicNo® overcomes the disadvantages while combining the benefits of commercially available micron & nano ZnO.
MicNo® is a single novel ingredient with the added value of,
UVA, UVB & Blue Light protection
High SPF ratio per % mass
Excellent dispersion properties
Very low uncontrolled agglomeration
Opportunity for formulations to be preservative free
ZnO is already in use in daily care products as a bulking agent, colourant & skin protectant. For formulators wishing to add UV protection to daily care products, ZnO works well since it is considered the most effective broad-spectrum UV filter.
MicNo® has a higher absorbance of UV rays than conventional micron & nano ZnO. This results in a higher protection against UVA, UVB & Blue Light by percentage mass & a higher SPF ratio per percentage mass.
With its novel hexagonal shape, MicNo covers a larger surface area per percentage mass than conventional ZnO. This means less ingredient is required to achieve the formulators needs, allowing for more cost-effective formulations.
The broad spectrum antimicrobial properties of MicNo® allow for formulations with less ingredients. Less preservatives are required if MicNo® is included in formulations, with preservative free formulations a possibility. Reduction of preservatives makes the formulation kinder to skin & the environment & also translates to lower formulation costs.
Research has shown MicNo® has a very positive profile for cytotoxic, genotoxic & phototoxicity, making MicNo more biocompatible & safer for humans & the environment. MicNo® does not accumulate in plant roots or permeate the skin’s epidermis, decreasing the chances of allergic reactions.
MicNo® exhibits a higher visible light transparency resulting in none whitening formulations but with a continuous coating over the skin with pore channels that make ventilation of the skin efficient, bringing a cooling effect in addition to smooth, visually & aesthetically pleasing formulations.
|SAMPLE||SPF||CoV %||UVA||UVB||UVA/UVB||CRITICAL WAVELENGTH (nm)|
|MicNo Soft Touch||32.84||10.26||28.16||33.72||0.84||375|
MicNo® powders exhibit high UV protection and good visible light transparency. In-vitro results according to COLIPA Standard Analysis of daily care formulations with MicNo shows High & Broad Spectrum UV protection and well visible light transparency.
The Clear Choice For UV Protection Daily Care Applications
This good visible light transparency means that the white cast effect associated with conventional ZnO is reduced for daily care products. MicNo’s nano-porous structure naturally creates a more ivory/beige colour, due to structural colouration, as opposed to the milk white colour that is currently associated with ZnO.
