Disinfection with ethanol and isopropanol

Atomiser Pump Spray Senjo Color

Not only in times of Corona (COVID-19 Coronavirus SARS-CoV-2) should attention be paid to the reduction of germs, bacteria and viruses. Especially in make-up, children’s make-up and body painting, the make-up artist bears the responsibility for his clients.

While thorough washing with soap and water is usually sufficient for hands, a little more care is needed for brushes and the workplace.

What is the difference between bacteria and viruses?

Bacteria and viruses can both make you sick and are invisible to the human eye. They do not have much else in common.

Bacteria are visible under a classic microscope. Viruses are almost a hundred times smaller and can only be seen under an electron microscope.

Bacteria have a cell wall and cell structure in which metabolic processes take place. They reproduce independently through cell division.

Viruses do not reproduce independently. They need a foreign cell to do so.

This means that they are not independent living beings, like bacteria.

What does this mean for us now?

Viruses are dangerously contagious and die after some time without a host cell.

Bacteria continue to multiply on brushes and sponges if they have enough food. And the skin scales of a human being are a special delicacy…

So always keep your hands, brushes, make-up colours and workplace clean and disinfect them regularly!

What is disinfection?

Disinfection means to make something germ-free or to reduce germs considerably. In this way, viruses and bacteria are rendered harmless and inactive.

How does a disinfectant work?

The mode of action of disinfectants cannot be generalised. Depending on the agents used and their area of application, the effects vary.
In the case of enveloped viruses such as Corona, for example, the protein envelope of the viruses is dissolved by the alcohol.
To disinfect against bacteria or fungal spores, the disinfectant/alcohol must remain on the object for some time in order to kill the bacteria/spores.

What disinfectants are available?

Roughly speaking, we use disinfectants for our work when dealing with customers for make-up, face painting, children’s make-up, etc. We use agents for surface disinfection, hand disinfection and brush/tool disinfection.

Overall, we distinguish between the following impact classes:

bactericidal: against bacteria
fungicide: against fungi
limited virucidal: against enveloped viruses (HIV, hepatitis B/C viruses, …)
virucidal: against enveloped and non-enveloped viruses (e.g. Noro viruses, Corona…)

Since we have to deal with bacteria the most in our work, bactericidal disinfections are therefore the main focus.

Therefore, ethanol and isopropanol-containing agents are the best choice for us.

We offer these directly in the shop. Special combinations of active ingredients are available in specialised shops and pharmacies.

What is surface disinfection?

When disinfecting surfaces, ethanol 70%, for example, is applied to a large area before and after work at the make-up area and removed after an exposure time of about 3 minutes.
Any residues of pathogenic bacteria, spores or viruses are then removed and guarantee hygienic work.
There are also numerous broad-spectrum agents, but these are more likely to be of interest to clinics and laboratories.

How long do you have to disinfect your hands?

By disinfecting the hands, I reduce the number of germs and thus the risk of transmission.

Apply approx. 3ml of disinfectant to the hand and spread thoroughly. Do not forget the palms, backs of the hands and also the spaces between the fingers and the fingernails. About 30 seconds is sufficient.

As the skin is dried out during disinfection, skin protection is included in special hand disinfectants. Nevertheless, the hands should be well lubricated after use, as the skin is attacked by the alcohol used.

In most cases, proper hand washing is sufficient.

How do I wash my hands properly?

I can generally clean my hands very well with soap and water. The surfactants already destroy a large number of dangerous pathogens.

Soap up thoroughly, soak the palms, backs of the hands and also the spaces between the fingers and the fingernails thoroughly. Allow about 30 seconds for this. Then rinse thoroughly and dry well.

Even enveloped viruses, such as Corona, cannot tolerate the mixture of water and soap for long. The lye attacks the viruses’ envelope and causes them to burst open.

What is isopropanol?

Isopropyl alcohol is known by many names. We use other names here, such as isopropyl alcohol, IPA or 2-propanol. isopropyl alcohol is obtained chemically by hydration of propene or catalytic hydrogenation of acetone.

Disinfection effects of isopronanol in relation to concentration:

from 13 % microbiostatic
over 30 % microbiocidal
from 80-90 % against noroviruses

You can buy cosmetic isopropanol in the following containers:
100ml, 250ml and in the 1.000ml bottle.

What is ethanol?

Ethanol is produced by alcoholic fermentation from biomass or chemical synthesis from water and ethene.
It is used for technical purposes, e.g. for cleaning.

Disinfection effects of ethanol in relation to concentration:

from 10 % microbiostatic
above 30 % microbiocidal
70 and 80 % against bacteria

You can buy cosmetic ethanol in the following containers:

250ml (96%) and in the 75ml hand spray bottle (70%).
