![]() To be essentially the same as water), but you may need to adjust the Propylene Glycol concentration for best defoaming results. It will not harm the record (the Hansen solubility analysis shows 100 ppm Just he advised that I have not actually tested this blend. So, the best (and cheapest) ultrasonic cleaner 'may' be a blend of the following two ingredients. Note that 100% propylene glycol is not compatible with records, but diluted sufficiently is safe. Propylene glycol is also very hydroscopic (absorbs moisture from the air) so you will see where it is used for humidors. ![]() ![]() The non-ionic surfactant in Kodak will foam and has a low cloud point, but the propylene glycol is a weak solvent, is a preservative, is very water soluble and can act as weak defoaming agent. Kodak Photo-Flo 200 is a blend of 10% non-ionic surfactant and 30% propylene glycol. ![]() However, I was working with someone who was using a blend of ILFOTOL and Kodak Photo-Flo 200 and they were not seeing any foam, but the solution was not clear. Because the 15-S-3 is not water soluble, you may leave a film on the record if you do not rinse. Tergikleen which is a blend of Tergitol 15-S-9 and 15-S-3 does not foam, and the reason is the water insoluble 15-S-3. Most are associated with an insoluble component be it a hydrocarbon oil or a silicone oil. There are a number of different chemistries available for defoaming. Degassing the tank prior to adding the chemicals will reduce the development of foam. Otherwise, for those that may be using Tergitol 15-S-9 or Ilford Ilfotol in an ultrasonic tank, both of these products can produce foam. The wetting by the surfactant dissipates/removes any static charge that may be on the record. It contains only a non-ionic surfactant and a biocide. I'm a biologist, used these chemicals throughout my career in molecular ILFOTOL contains no 'anti-static" ingredients. These compounds make the water "wetter" they lower the surface tension so the cleaner can get into tiny more hydrophobic spaces on the LP. There are other pure non-ionic detergents, e.g., Tween-80, Nonidet P40, etc, that are either identical chemically to Triton X100 or work just as well. I always use Triton X-100 which comes in near 100% solution, and little bit, a drop or two in a liter of cleaner, is all you need. (I just looked this stuff up I don't pretend I always knew it, but I have known not to use Photo-flo, though many do.) Propylene glycol is arguably not good for LPs. The non-ionic detergent component is less than 10% of the make-up of Photo-flo. Kodak Photo-flo is a mixture of propylene glycol (20-40%), aka "anti-freeze", and a non-ionic detergent that is probably in the same family with Triton X-100 but is chemically a bit different. It is a true surfactant used mostly in biology and I suppose for industrial processes. Push/Pull processing by adjusting temp.Ml89009, Triton X-100, recommended by Mijostyn, is a non-ionic detergent, otherwise known as "2-ethanol". Worlds fastest process at 27☌ in just 3min!
