Good day Mijostyn,
I will address your four most recent posts at the same time. First, I need to make some adjustments. You have presented very good and clear questions, however, there are a few very minor deviations in the formulations you presented.
My first assumption is that you stated that you are using "Triton X" as a surfactant. I believe that I am correct to assume that you are using "Triton X 100".
Triton X 100 is the most commonly used Triton surfactants manufactured by Dow Chemical. You may not be aware of this trivial bit of information and history about Triton X 100, but, sometime around 1960, TritonX 100 was the Reference Standard of nonionic surfactants. It was the base to which all other nonionic surfactants were compared. In fact, to this day, it is the "Medical Standard" that is used in Medical experimentations. Even if other surfactants are used ( and, they mostly are not), Triton X 100 is also used. This is very important because Medical Research that is done today can accurately be compared and judged to studies that were done more than 63 years ago. This is very important in Medical Research.
Nevertheless, the selection of Triton X 100 for cleaning vinyl records is a good choice, not the best or close to the best, but a good choice. And, if you already have access to Triton X 100, I do not see any reason to make a change unless you are interested in making the "Very Best". Stick with the Triton X 100, but you proportionally need to incorporate more into your formulation. I thought that I would first alter what you are using and make it more relatable to the "Very Best Record Cleaning Formulation" that I initially presented, and then I though to also provide a comparison, and then make comments about the ingredients in question. I decided to refer to your formulation as "Mijostyn’s Good Record cleaning Formula"
"Mijostyn’s Good Record Cleaning Formula
Ingredients: Parts by Weight (Grams)
Distilled Water 779.772
Ethanol 220.000
Triton X 100 (Dow Chemical) 0.228
Benzalkonium Chloride 0.000
1,000.000
Now, if I were to take my formulation and relate it to what you have been using it would read as follows for comparative purposes only.
Ingredients: Parts by Weight (Grams)
Distilled Water 941.499
Denatured Alcohol 50.900
Benzalkonium Chloride 7.600
Triton X 100 (Dow Chemical) 0.001
1,000.000
You should not be concerned with the "Distilled Water" that you purchase at a supermarket, or drugstore, or Walmart. As long as it is stated as distilled and not deionized.
I do not know if your intent to use Benzalkonium was as a "antimicrobial agent" or as an "anti-static agent", or both? Nevertheless, you do not need an antimicrobial agent. Also, the selection of this agent as an anti-static agent can only cause problems, also, if intended for such a purpose, the amount used is extremely excessive. There are much better and easier ways to control static, and, they should never be incorporated within a cleaning formulation.
Now to the denatured alcohol versus "Pure Ethanol" aspect. In one respect using denatured alcohol is LESS DESTRUCTIVE than using another alcohol such as, isopropanol, because it first depends upon the concentration of ethyl alcohol in the denatured. The Ethyl alcohol concentration can be as low as 60%, or 90%, or most often 95%. The majority of the denaturant is "Methyl alcohol". And, I mentioned that ethanol has NO EFFECT on vinyl records, methyl alcohol does, but, although it is destructive - it is the least destructive of the more common alcohols. However, you should use Ethanol purchased at a liquor store ONLY. It is not worth saving a few pennies and progressively damaging your records over time. The other ingredients used to make alcohol denatured are copper sulphate (used for coloring only, and not a big problem), Methyl Ethyl Ketone, Methyl Isobutyl Ketone, and denatunium (to make it bitter tasting), and pyridine (to make it smell to high heaven). There are also others. The exact quantities are no longer governed and benzine has been banned. But it is important to note that even in very minute quantities they are extremely effective. Please, please use only ethanol for numerous reasons. I will be preparing a graph for all to see why the level of 22.000% is important, and not just a number I picked out of a hat. The graph will (or should) make it clear.
So, scrap the BAK, feel confident in your distilled water purchases, purchase and use only ethanol, and significantly increase you level of Triton X 100 by a factor of 5+.
I noticed that many use volumetric methods of making their formulations, I intend to convert my presented formulation in a volumetric format as well very shortly.
I hope this has cleared some things up for you and has been helpful. If you follow what I have stated, you will no longer have any residue problems. Also, Triton X 100 is not as low foaming as the Tergitol 15-S-7, but it is manageable and will not produce unnecessary spotting and quickly dry spot-free.
