Resistance plastics HDPE, CDH, DMSO

Plastics HDPE, CDH, DMSO resistance

Again and again, the question of the resistance of plastics to CDH and DMSO is asked. Therefore, I have written a summary of my experiences here.

Which bottles are best?

The highest resistance of DMSO and chlorine dioxide solutions up to 0.3% is provided by glass bottles.

That’s why I offer the products mainly in glass bottles.

Questions regarding DMSO:

Do solvents from HDPE bottles get into the DMSO solution?

– In general, it can be said that all solvents somehow dissolve in liquids. This applies to the drinking water bottle made of PET just as much as other plastics.

DMSO in a high concentration also dissolves plasticizers from plastic as a solvent.

This can be checked and seen for yourself with a commercially available disposable syringe made of HDPE. If the DMSO is applied undiluted with it, small, even visible streaks form.

– If you rinse the syringe or a bottle to be used beforehand with a little DMSO, this will no longer happen.

With the syringe, you can also notice immediately after rinsing that it becomes more difficult.

The next question is, however, how much plasticizer is it at all?

Another question would then be: Does a trigger in the present concentration harm me?

Furthermore, the question: Does the plasticizer not also remain dissolved in the DMSO and therefore does not harm at all?

Carcinogenic effects (carcinogenic effects) are becoming increasingly difficult to believe according to the current, ever-increasing new findings on cancer. Because we now know that “cancer” requires many factors that are not only related to any substances. It is then attached to a substance

It is becoming increasingly difficult for me to establish what we have had in drinking water for a long time. There is always much more to it.

By the way, HDPE is not dissolved by DMSO. Therefore, a consistency is given, even in the long run. And HDPE is one of the most widely used plastics for the transport of chemicals, also for DMSO.

I don’t know of any supplier who does not supply DMSO in HDPE containers. For this reason alone, a triggering cannot be prevented at all.

So it is ultimately a question of self-responsible assessment, to which we still have to get used to in part.

So many substances that have fallen into disrepute are not what you say about them. That’s why I rely on my own experiences.

If HDPE were to cause significant problems in principle, we would have a completely different impact. In the meantime, the entire water supply (pipes) is being converted to plastic. There are certainly different quantities than with a cap or a bottle…

I think, right now, many people are poisoning themselves with substances they don’t know in order to gain supposed “freedoms”. The question of solvents or plasticizers seems to be too exaggerated.

From my many years of experience, I can report that I use DMSO myself in HDPE bottles for use on the go.

I have not yet been able to identify any problems with this. This also applies to CDH3000. I’ll go into that below.

What about HDPE?

HDPE is one of the most durable plastics in the chemical industry. Only PP, is even more consistent. Almost all durable closure systems are made of HDPE. There is simply nothing else.

However, PET has a higher degree of plasticizers. Therefore, the bottles are also easy to press. But for this reason, you will not find any use in the chemical industry.

What about chlorine dioxide solutions?

Retailers from the very beginning use plastic (HDPE). And this to this day.

From my own experience I know that chlorine dioxide solutions HDPE bottles are apparently oxidized by a longer use of plasticizers. Because at some point the bottles become brittle.

That’s the downside, unlike glass bottles.

Plastic in closures a problem?

Not in my view. On the one hand, the closures are very small and have hardly any significant area.

So far, I have hardly been able to detect any signs of fatigue in the dropper closures. Only after years of use.

Spray caps can reach their limits faster in terms of durability. But the consistency is also relatively good. For a permanent use, however, I would not use them or exchange them regularly.

If one refers to the experiences of the “first hour” with chlorine dioxide and the alternative application, completely different substances and containers were used here, which seem even more questionable.

I only sell chlorine dioxide solutions in glass bottles, but I also like to use HDPE bottles with sprayers for mobile use. However, since some customers have repeatedly requested the version of CDH with the white HDPE bottle, I still have it in my assortment.

Lately, a lot of fear and panic has been spread, because this is a means of power. Fear is not a good guide. Experience is already better suited.

Certainly, there are completely different dangers and toxins that should be of greater concern to us at the moment. HDPE is probably less of a part of it after so many years.

So far my assessment from here.
