Nail Polish Good Manufacturing Practice

Nail Polish Good Manufacturing Practice (GMP)


Good Manufacturing Practice or GMP plays an essential role in a cosmetic and independent nail polish manufacturers duties and obligations especially in light of the 2013 EU Cosmetic Regulations where GMP is one of the main focal areas. Essentially GMP refers to a set of practices and procedures that ensure that your products are produced in a clean environment and do not become contaminated during the manufacturing process.

It is vital that microbes are not introduced into your products while you are making them as microbes can degrade your cosmetics and make them harmful for the user. GMP procedures are concerned primarily with product quality therefore little focus is placed on the Health and Safety of personnel and equipment. This is an area that nail polish manufacturer will have to seek alternative guidance on.

The ISO standard 22716 is a set of standards and guidelines created by those in the cosmetic industry that outlines best Good Manufacturing Practice (GMP). If you follow the guidance set out in ISO 22716 it would be assumed that you are compliant with the Regulations but it is not a legal requirement. As a nail polish manufacturer you can create your own GMP as long as it achieves the same objectives as those stipulated in ISO 22716.


The important points to remember and implement are as follows:

   1) When you are making your nail polish it must be made in such a way as to prevent microbes entering your products so that they will not pose any harm to your consumers.

   2) You can use ISO 22716 as your GMP procedure or you can create your own as long as it achieves the same objectives.

Now once you have adopted your own GMP guidelines are there any key considerations more specific to nail polish making?

It is vital that your finished polish creates a nice, smooth homogeneous film that is free from unwanted particles such as dust and debris. Nail polish contains high levels of solvents so it potentially kills microbes. However, it is still important to prevent dust and impurities from getting into it.

In the ISO 22716 standards ventilation is discussed. In section 4.5.2 it states -

4.5.2 Windows should be of non-opening design where ventilation is adequate. If windows are opened to the outside environment, they should be properly screened.

As you can see ISO 22716 states that open windows should be screened. This must be to prevent insects and other unwanted elements from entering the manufacturing facility i.e. your lab or the space where you make your polish. Potentially these elements can contaminate your products, equipment and surfaces. So windows and openings must be screened in some way to prevent unwanted debris from getting in.


NOTE - When you are making your polish you should always have excellent ventilation for your own safety so that you do not breathe in all the solvent fumes and vapours from the ingredients that you are using. So it might be a good idea to invest in an adequate general exhaust ventilation system which typically consists of an exhaust fan, mounted in the ceiling or wall, that pulls the air out of your workspace and discharges it outdoors, if you are doing this on an regular basis. In addition, you should at the very least be using some form of respirator/mask to minimise and prevent inhalation of vapours as well as the powdered pigments that you may be using to make your polish. Please seek independent guidance on the type of mask or respirator that you should use.

Another important part of your GMP might be that you regularly vacuum your workspace and wipe down the walls and ceilings. It might sound a little excessive but this will also minimize the dust in your workspace.

Covering you hair and clothes will also prevent unwanted particles from entering your polish and should be an essential part of your GMP procedures and guidelines.

Put simply Good Manufacturing Practice (GMP) is comprised of mostly common sense procedures to help keep your products microbe free and fit for public consumption.


Happy and safe nail polish making :)
