Father Frost, tattoo inks and pick-up stations
The dark, cold season has been present for a few weeks now, and the increased use of packing stations naturally raises a special question for our industry: What is the situation with tattoo inks that spend the night in a packing station in winter?
How do cold and frost affect tattoo inks?
What do the shipping companies say?
The first question you have to ask yourself, of course, is whether it will be as cold in the package and on the product itself as the ambient temperature is outside the packing station. Temperatures in Central Europe tend to drop into the minus range at night in winter. Values such as -5 to -10° are still possible nowadays, despite the milder climate. So of course you would expect this cold to creep up to a package within 24 hours.
That's why we first contacted the shipping companies and were told that you can't make a general assumption about the ambient temperature of packing stations. Some are in sheltered places, where no frost at all occurs at night. Others are in exposed locations and can therefore be affected by wind and weather. Generally, the shipping service provider is not liable for frost damage, or in the summer even at very high temperatures. It is the responsibility of the recipient to pick up the package in time, so the statement.
What do tattoo and PMU ink manufacturers say?
We understand that the shipping service providers keep this request relatively flat, it should also be catchy that with unheated packing stations at different locations a defined statement is not possible. That's why we went further and wrote to the tattoo and PMU ink manufacturers.
The statement here is that there are, of course, in general storage recommendations that range from 4 °C to 35 °C. Each manufacturer has different specifications here, and these can also be seen on the respective product bottles, on the label. This labeling is mandatory, not only since the REACH law, and therefore you will really find this information on every tattoo and permanent makeup color. In any case, it is important to prevent direct sunlight and thus heat, as well as direct frost and cold. These two conditions are achieved, however, only if the tattoo pigments are also directly exposed to such external conditions for a long time.
All manufacturers of tattoo colors agreed that this is not the case with regular shipping and short-term storage of 24-48 hours in packing stations. Generally, yes the air is kept warm by the packing station and by the package so far that no complete frosting takes place here, at least not in our climes. We have also received several times the statement that low temperatures per se do not damage the paint. One should tattoo colors or permanent makeup colors after opening and proper shaking in color caps eingefülle to test whether the color behaves differently than usual. Only in extreme cases, according to manufacturers, it is possible that the color is lumpy and in this case you would actually have a damaged product. However, each manufacturer considers this very unlikely under the normal conditions mentioned. Therefore: tattoo and PMU colors also do not store in the freezer! ;)
