Hi,

I would like to ask for some advice how to dilute squaric acid (C₄H₂O₄) from a 98% to a 2% solution. To be precise my question is what can I use as an ingredient to dilute it down without it separating once constituted? For example I have tried mixing it with coconut oil, but it seems to separate from it.

 

The acid has good soloubility in water. About 20 g/l at 20°C.

But in oil it is almost not solouble.

I dont know what is the problem. To dilute a solution   from 98% to 2% is normal calculation method like cross rule and percentage calculation.

To mix it with oils you need surfactants like soap.

Nobody said to pour water into the acid.

But this rule is so far only valid for sulfuric acid. Other acids don't develop so much heat.

Not  usually important with organic acids.

OK, I didn't know (or possibly remember) that.  Thanks for the info.

What are you planning to use squaric acid for?

Thanks for the reply. Calculations are not a problem. I forgot to mention I want to make it into a topical solution that can be applied onto the skin. Therefore water is not suitable, as it needs to have a thicker structure and the solution must contain non-toxic ingredients.

Unfortunately, we are not in the business with helping with such questions. I also do not believe that squaric acid itself has any medical benefits, so it is not clear what this would achieve.
