Yes, the isopropyl alcohol is just a carrier for the fatty alcohol, similar to how calcium hydroxide is used as a carrier for cetyl alcohol in HeatSavr. The isopropyl alcohol will mix with water and then evaporate and will not form a surface layer -- it's the fatty alcohol that does that.

These liquid solar blankets somewhat work. i mean they work well for the first while but then they kinda die (this example is of the fish you stick in your pool), but the kind where you pore an actual liquid in your pool EVERYDAY works better, just to let yalll know

Can I use my solar cover with the solar pill, or does that use up the chemical since it floats on the top? In other words, does the solar pill chemical end up sticking to the blanket, thus wasting it. My husband thinks the cover does a better job, and I don't want to use both if it wastes the chemical.

Well yes the composition of Heatsavr liquid is almost all IPA (isopropyl alcohol) .. but the active ingredient
is cetyl alcohol. The important fact is that plain cetyl alcohol is a solid waxy substance. (you can even get it on ebay) and harmless (used in cosmetics etc) - but SOLID. As such you can't easily disperse it on the top of your pool. :-) So for swimming pools the trick is to dissolve the waxy stuff in harmless IPA. Once in contact with water the IPA floats and spreads out .. and evaporates leaving tiny molecules of cetyl alcohol near invisibly spread out on the surface. Whether there is any calcium hydroxide powder in there too I can't say. It might help disperse the stuff initially but it is not going to stay there forming a part the liquid layer - calcium hydroxide (lime) just dissolves so easily in water. So to sum up: if you want you could buy a small quantity of cetyl alcohol and dissolve it in gallons of IPA and try that out :-) ! You certainly don't need much .
How much? well if you pour out a glass of heatsavr liquid and let the IPA evaporate (which it will do quite quickly) you'll be left with the cetyl alcohol vax .. and then you will have an idea. My guess is there is a TINY amount of the wax - but you'll see it.

Stearyl alcohol and cetyl alcohol at 4.6% each are the active ingredients in WaterSavr. I found this in a "Product Evaluation" for WaterSavr. I suspect mixing these two ingredients with Isopropyl alcohol would work very well, to slow swimming pool evaporation.

Has anyone tried adding this to a jacuzzi at night (in addition to using a cover) to minimize heat loss?

I would think that a good cover would do most of the heat retention, but I suppose you could try these liquid solar blanket products to see if it makes any difference.

As for the stearyl alcohol in WaterSavr, this is an alcohol with 18 carbons while cetyl alcohol is one with 16 carbons so they are similar and would tend to form a one molecule thick layer on the surface of the water with the alcohol end sticking in the water and the carbon chain sticking out into the air. These products can work reasonably well when the air is still. They do not work very well when there is wind as this tends to push these substances to one side of the pool. They also do not work very well when there is a disturbance of the water surface so work better when the pump is off and the water is still.

Sorry to be adding to this forum so late in the game, but just found it!

Does anyone know if the liquid solar blankets work effectively with and are safe to use with salt chlorine generators?
