Nano Power

Nano's, we have all heard bits and pieces on Nano Particles. But what are they? How do they effect your Cosmetic
Products and are they dangerous?. Our world is made up of Nano-Particles/Material, they are the tiniest little particles.

Have you ever seen those Science programmes in which the electron microscope can show you the the hairs on a fly or an even smaller particles than that?... Amazing!
Nanomaterial/particles may be in cosmetics, sun creams, toothpaste just to mention the most common products that may contain Nanomaterial.
So what are they?
Nano particles are the smallest of particles, ranging from 0.2nm to up around 100nm. In general, a Nanoparticle is a material with individual parts that are on the nano-scale. 
One of the most commonly used nano-material in Cosmetics Titanium dioxide. 
Titanium dioxide is also a mineral that is part of our natural environment as well.
Other Nano Particles that maybe  in cosmetics raw ingredients could include Zinc oxide and Carbon black. You may see an ingredient in the list that you have heard is a nanomaterial but is not listed with the “(nano)” suffix. It is important to remember that some ingredients that are used in the nano form can also be used in a non-nano form. For example, larger particles of titanium dioxide, which would not be labelled “(nano)”, can also be used as a UV filter and as a white colourant  which these have been used in conventional products for decades.  Also that Nano Particles/Material should be on the labelling of products that contain this.
Since 2009 the European Commission has stated that not more than 25% of the Nanomaterial is allowed for use in or around the Mucus Membrane area. 
But what is the Mucous Membrane area?
The Mucous Membrane areas are, according to the EU Cosmetic Directive
-the oral cavity, (Lips/Nose/Mouth)
-the rim of the eyes,
-the external genital organs,
-the lungs.
Speak to your manufacturer that you buy your raw material from and ask if their products contains Nano Material.
With regards to your own cosmetic formulations, that you want to sell on the market to the public, it is advisable that you speak with your Safety Assessor to make sure you are staying within the legal required Nano % limit, if your formulation contains Nano material and label the product accordingly.
In a nutshell for  DIY Eye Shadows or DIY Lip Sticks, if  the Titanium dioxide/Zinc oxide or Carbon Black do contain Nano Particles in the formulation, keep them under the EU Regulation % amount of not more than 25% of Nano Material in the final product.
I do not claim to be a Cosmetic Scientist, this guide is for information purposes only. It is up to you to make your own mind up with regards to Nano-material. There are Pro's and Cons for using products containing Nano-materials, so here
is a website that you can look up to make your own informed decisions.

NANO DEFINITIONS: References used from “European Commission Health & Consumer Protection Directorate-General”.
Nanoscale: having one or more dimensions of the order of 100 nm or less.
Nanoscience: the study of phenomena and manipulation of materials at atomic,
molecular and macromolecular scales, where properties differ significantly from those at a larger scale.
Nanotechnology: the design, characterization, production and application of structures, devices and systems by controlling shape and size at the nanoscale.
Nanomaterial: material with one or more external dimensions, or an internal structure, which could exhibit novel characteristics compared to the same material without nanoscale features.
Nanoparticle: particle with one or more dimensions at the nanoscale. (Note: In the
present report, nanoparticles are considered to have two or more dimensions at the
nanoscale).
Nanocomposite: composite in which at least one of the phases has at least one
dimension on the nanoscale.
Nanostructured: having a structure at the nanoscale.
