Zinc Oxide (ZnO) is traditionally used as a UV filter in sunscreens but is also commonly found in coloured cosmetics as a bulking agent & colourant. It is often found in mineral cosmetics as a pigment. It improves cosmetics’ adhesiveness to the skin, & its whitening, mattifying & covering properties make it efficient as a component of powders, foundations, eyeshadows & blushes.
Entekno Materials have designed & developed a novel ZnO form using their innovative MicNo® ZnO Particle Technology. MicNo combines the benefits & overcomes the disadvantages associated with micron & nano ZnO currently on the market. It 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
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.
In addition to being an excellent UV filter, with a higher protection against UVA, UVB & Blue Light by percentage mass & a higher SPF ratio per percentage mass than conventional micron & nano ZnO, MicNo has many other qualities that make it an ideal additive for colour cosmetics.
MicNo has a nano-porous structure that naturally creates a more ivory/beige colour, due to structural colouration, as opposed to the milk white colour that is currently associated with ZnO. With a higher visible light transparency when used at the same concentrations as commercial transparent nano ZnO, MicNo also produces none whitening formulations.
The excellent dispersion properties of MicNo allow for smoother formulations making it an ideal option for a bulking agent & emulsifier. These characteristics make MicNo easier to incorporate into coloured cosmetics than conventional ZnO.
Another important feature of MicNo is its broad spectrum antimicrobial activity against a range of micro-organisms & fungi, allowing for formulations with less preservatives or even preservative free. Less preservatives result in kinder to skin & more environmentally friendly formulations. Also, less ingredients in a formulation could translate to reduced cost formulations.
In an industry that is focusing increasingly on natural & environmentally friendly cosmetics, MicNo is the ideal ingredient for your cosmetic formulations. MicNo is a COSMOS ECOCERT certified natural ingredient, with its micron sized particles ensuring it is biocompatible & safe for both humans & the environment.
