MicNo Sun Care Application

Entekno Materials has designed & developed an innovative MicNo® ZnO Particle Technology that provides sunscreen formulators with a single novel ingredient for their broad spectrum UV protection needs with the added benefits of,

  • UVA, UVB & Blue Light protection

  • High SPF ratio per % mass

  • High transparency

  • None whitening

  • Natural ingredient

  • Environmentally friendly

  • Excellent dispersion properties

  • Very low uncontrolled agglomeration

  • Opportunity for formulations to be preservative free

MicNo is a unique, hexagonal platelet morphology that allows MicNo to behave as safe micron particles over the skin & transparent nano particles under the light; exhibiting only the positive elements of micron & nano ZnO.

Proven to have a much higher absorbance of rays within the UV wavelengths than conventional micron & nano ZnO, MicNo offers a higher protection against UVA, UVB & Blue Light by percentage mass & a higher SPF ratio per percentage mass.

With its novel hexagonal structure, MicNo covers a larger surface area per percentage mass than conventional ZnO. This allows formulators to use less UV filter to achieve their sun protection needs, allowing for cost-effective, high SPF formulations.

MicNo® Sun Care Application particle technology combines the strengths of micron and nano size scales while reducing/eliminating their weaknesses.

MicNo exhibits high transparency which results in a formulation that is none whitening, even at 25% MicNo & offers a much more visually pleasing formulation.
Not only is MicNo a superior UV filter, it is also a safer option. Research has shown MicNo has a very positive profile for cytotoxic, genotoxic & phototoxicity, making MicNo more biocompatible & safer for humans & the environment.

MicNo also offers the opportunity for decreased or preservative free formulations, due to its broad spectrum antimicrobial activity against a range of micro-organisms & fungi. The need for less preservatives would result in kinder to skin & environment formulations but also a decrease in total formulation ingredients which could translate to reduced formulation costs.
