The ILFOTOL contains no 'anti-static" ingredients. It contains only a non-ionic surfactant and a biocide. The wetting by the surfactant dissipates/removes any static charge that may be on the record.
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. Degassing the tank prior to adding the chemicals will reduce the development of foam. There are a number of different chemistries available for defoaming. Most are associated with an insoluble component be it a hydrocarbon oil or a silicone oil.
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. Because the 15-S-3 is not water soluble, you may leave a film on the record if you do not rinse.
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. Kodak Photo-Flo 200 is a blend of 10% non-ionic surfactant and 30% propylene glycol. 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. Propylene glycol is also very hydroscopic (absorbs moisture from the air) so you will see where it is used for humidors. Note that 100% propylene glycol is not compatible with records, but diluted sufficiently is safe.
So, the best (and cheapest) ultrasonic cleaner 'may' be a blend of the following two ingredients. Just he advised that I have not actually tested this blend. It will not harm the record (the Hansen solubility analysis shows 100 ppm propylene glycol to be essentially the same as water), but you may need to adjust the Propylene Glycol concentration for best defoaming results.
Tergitol 15-S-9 at about 0.01 to 0.02% (100 to 200 ppm). The Tergitol 15-S-9 is 100% concentrated, so 0.01 to 0.02% = 0.1 to 0.2 mL/L; which is equal to 2-4 drops/L. If you are outside the USA, use ILFOTOL instead. If you add 0.9 tablespoons (= about 15 mL) of ILFOTOL to 3.3 gallon of water you will get 62.5 ppm on non-ionic surfactant.
Propylene Glycol USP/EP (PG USP/EP) CAS # 57-55-6. This is a concentrated pharmaceutical/food grade version that is quite cheap, very safe and easily purchased - such as Propylene Glycol - 250mL (8.45 oz.) - USP Food and Pharmaceutical Grade - Highest Purity, Humidor Solution, Humectant, DIY, Cosmetics: Amazon.com: Industrial & Scientific Adding to get 50-100 ppm Propylene Glycol may do the trick to control foam (and act as a preservative) and this would be 0.005 to 0.01% or 0.05 to 0.01 mL/L or 1-2 drops/L.
FWIW - when mixing chemical, you may find disposable LDPE pipettes to be very convenient. They are very cheap - 100pcs Plastic Disposable Transfer Pipettes - 3ml Plastic Calibrated Graduated Eye Dropper Suitable for Lip Gloss Transfer Essential Oils Science Laboratory Experiment: Amazon.com: Industrial & Scientific
Hope this is of some help,
Take care,
