Liquid Solar Blanket

They shouldn't matter. They generally stay on top of the water as a thin film and if they do get sucked into the skimmer and go through the SWG they probably won't break down very much because they are mostly long-chain saturated organics and do not have nitrogen nor sulfur sites (nor double bonds) where chlorine would normally attack. I don't believe the increased salt levels will interfere with this product either.

Just remember that the product doesn't work well in windy environments.

Yes that is completely true, rubbing alcohol is made of mostly ethanol though with isopropanol making it deadly to consume (pentanol is deadly to consume even in low quantities). Ethanol is the key ingredient in alcoholic which makes people drunk. This means that rubbing alcohol is not what they use because it reacts with people in a very negative way (toxic/intoxication). Water and enthanol/pentanol are also both polar and so the two compounds will mix. Therefore the compound must be a non polar compound in order for the compound to be immiscible and therefore make 2 layers. (this follows the old saying like dissolves like, think about oil and water, where oil is a non polar compound). Also, the compound would have to be less dense than water so that it will float to the top. Also the evaporation of ethanol is much greater than water due to its lack of hydrogen bonds making the intermolecular forces less strength and thereby easier to evaporate.

So therefore, the compound would have to be some kind of non polar compound with high intermolecular forces, most likely some synthetic compound or a derived chemical from a naturally occurring polymer, or something of that nature.

We've already talked about this earlier in this thread here. The active ingredient in these products is one or both of cetyl alcohol and stearyl alcohol. Calcium hydroxide is used as a dispersant (that dissolves in water) while isoproponol (isopropyl alcohol) is the carrier that evaporates.

We have an inground pool and use baquacil chemicals. I would like to try the solar pill to reduce heat loss but my husband is concerned about possible interactions with the chemicals. He says if we don't like it, how do we get rid of it. I can't answer that one. Can anybody help?

I doubt very much that there will be any interaction between Baquacil or the oxidizer used in such pools, hydrogen peroxide, with the Solar Pill chemicals.

My Pool: My pool is 18 X 36 inground, vinyl. I have a sand filter that I recently replaced with glass media. Sparkling clear and about 80 degrees today!

Yes, I have tried the solar fish and the solar pill by sea kleer. They both raised the temp by about 5 degrees for 2-3 weeks. It's worth it if you ask me!

I have made the liquid sular blanket with isopropyl alcohol and stearyl alcohol but it leaves a whitish depot ion the surface of the pool and doesnt not seem to dissminate over the entire pool

As I noted in an earlier post, calcium hydroxide is used as a dispersant and the exact proportions and formulation are proprietary, though this is described somewhat in patent 6,303,133 .
