Stains from shampoo or shower gel on textiles
Recently, someone asked again in the forum, so that they could remove the stains from the towels (textiles), she had already tried everything, bleach, Oxi, Gall soap, nothing helped. I already had my problems with that.
As paradoxical as it sounds, the culprit is in many shampoos and shower gels.
The issue has been discussed several times in the media, I know it not too long: many shampoos and shower gels contain a substance that is called Polyquaternium. Often there is a number behind it, for example Polyquaternium-7.
When the silicone became so discredited, the cosmetics industry manufacturers looked for cheap replacement and found it in Polyquaternium. With its net-like structure, this silicone replacement makes skin and hair nice and smooth, but when it comes to drying on textiles, there are stains that are definitely no longer removable. The negatively charged polyquaternium then acts on the fabric almost like a dirt magnet. It attracts the positively charged dirt particles dissolved in the wash liquor and one can only really throw away the relevant textiles. The NDR had even commissioned a professional cleaning company with a stain removal in a broadcast about it, unfortunately without result. The stain does not necessarily appear immediately, but with every wash it gets worse.
The fact that Polyquaternium is not biodegradable and that the acrylamide contained in PQ-7 as a contaminant is poison for the beneficial bacteria in our clarifiers is not surprising. Rising costs for wastewater are the result. If you want to know more, you can find the video from NDR on YouTube. Incidentally, Polyquaternium is also not good for the skin and hair, as it is even worse than silicone film-forming and deposited on skin and hair. Safe for children's skin and hair worse.
At least the stuff is declarable, ie. it has to be on the shower gel or shampoo when it's in it. The cosmetics industry wants to continue using Polyquaternium, because it is unbeatably cheap. I have now looked specifically for this tip again in the drugstore and was pretty scared, how many shower gels and shampoos still contain the stuff. The NDR found it in 11 out of 17 products at that time, I think there has not been much done yet.
In natural cosmetics, which are now also affordable in drugstores, Polyquaternium is not used by the way.
My concern now was to give you the information. What everyone does and what decisions he derives from it, of course, is up to you.
