Osmolality and pH can be very mysterious factors when it comes to lube. At least pH can be easily home tested, while osmolality levels remain nearly impossible to find.

A few manufactures do list their osmolality ranges though, and a few specify ‘low osmolality,’ so keep an eye out for it. Another thing to look out for is the presence of glycerin or propylene glycol which predict a high osmolality.

Below are a couple of links from people who were good enough to make spreadsheets on various lubes tested, or published, pH and osmolality range.
