How does Brushean disinfect makeup brushes and beauty tools?


Brushean’s  design features UV-C LED and ozone sterilization technology that kills 99.9% of all bacteria, germs and viruses which collect on the brushes. Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions. Ozone is an extremely effective disinfectant against bacteria and viruses that uses gaseous oxygen with an extra atom loosely bound to the oxygen molecule.  

UV-C technology destroys the microorganisms of the surface the UV hits while ozone destroys the microorganisms within the space that the ozone is active in. Ozone helps to sterilize in-between brush bristles for maximum effects.

 

What is ozone?

Ozone (O3) is an unstable gas composed of three atoms of oxygen. Two atoms of oxygen form the basic oxygen molecule (O2)--the oxygen we breathe that is essential to life. 

Ozone is produced by running an electric current to disassociate the O2 molecules into oxygen atoms and subsequently collide with oxygen molecules to form O3. 

It is unstable because the gas will readily degrade back to its stable state, diatomic oxygen (O2) with the formation of free oxygen atoms or free radicals.

The free oxygen atoms or radicals are highly reactive and they will oxidize almost anything (including viruses, bacteria, organic and inorganic compounds) it contacts, making ozone an enormously powerful disinfectant.

 

Is ozone safe to use?

Ozone is safe to use as long as it is not inhaled directly into the lungs. With our makeup brush sanitizer, ozone is being generated in an enclosed space, and users are instructed to keep the device shut while it is in use. This ensures that the ozone stays within the device for the purpose of disinfecting tools.      

Since ozone is an unstable gas, it will readily degrade back into its stable state, diatomic oxygen (O2). 

Ozone disinfection does not produce any harmful residues, and all residual ozone will be converted back to oxygen within a short time. Ozone is therefore considered as an environmentally friendly disinfectant.

It is not safe to inhale ozone because it can potentially damage the lungs. The same chemical properties that allow high concentrations of ozone to react with organic material outside the body give it the ability to react with similar organic material that makes up the body, and potentially cause harmful health consequences. 

Much of the literature that warns about ozone being harmful to health is directed toward ozone generators that are being sold as air purifiers. 

Brushean Makeup Brush Sanitizer is NOT an air purifier. Ozone is being generated in an enclosed space, for the purpose of disinfecting tools. Ozone is not harmful as long as the device remains closed while in use. 

Since ozone is an unstable gas, it will readily degrade back into its stable state, diatomic oxygen (O2). 

Ozone disinfection does not produce any harmful residues, and all residual ozone will be converted back to oxygen within a short time. Ozone is therefore considered as an environmentally friendly disinfectant.

 

Do you have laboratory testing?

Yes we do. Brushean’s Makeup Brush Sanitizer was tested at the Guangdong Detection Center of Microbiology. 

 

What is UV Light?

Ultraviolet (UV) light is electromagnetic radiation with a wavelength shorter than that of visible light, but longer than X-rays. 

Ultraviolet radiation covers the wavelength range from 100 to 380 nanometers. The disinfection process uses wavelengths in the UVC range from 240 to 280 nanometers, while the oxidation process uses the wavelengths down to the VUV range below 200 nanometers. 

 

Light Spectrum

 

How strong is the UV-C light in Brushean’s Makeup Brush Sanitizer?

The UV lamp used in Brushean’s Makeup Brush Sanitizer has a wavelength of 254 nanometer (nm)

Over 100 years ago, scientists discovered that if you exposed pathogens to UV light, their reproduction was limited. The UV light used, resided in the UVC range of the light spectrum. Specifically, they discovered that light in the 254 nanometer (nm) range was the most effective. 

Can UV-C kill coronavirus?

We at Brushean are unable to make any claims about UV-C light’s ability to combat Covid-19, but here are links to a few articles that do.
