Water is one of the best chemical solvents on God's green earth. But I digress.
Most of the fracking fluids being used have proprietary chemical compositions. Some have included benzene, a carcinogen. Various levels of gubmint are trying to demand disclosure of fracking fluid ingredients.
Corrections are always appreciated.
It has become common for companies to publicly list their chemicals. Exact ratios are left proprietary. But the chemicals themselves are available online:
Searchable database, still growing
Some companies list their chemicals directly online, sorted by area.

Some have included benzene
Would you please point to claim of benzene being used?
Some companies like Haliburton make Hydraulic Fracturing Fluids from ingredients sourced entirely from the food industry.
Various levels of gubmint are trying to demand disclosure of fracking fluid ingredients.
It is already state law in Texas to disclose. It hasn't slowed us down. Others have followed.

It was always required to have on site the Material Safety Data Sheets on site for all chemicals used, so it was available before, but not convenient to find.
Yep, and those are every bit as proprietary as the KFC recipe or the formula for Coca-Cola.
Technically, dihydrogen monoxide is a chemical, so is glucose, so is oxygen, but humans aren't going anywhere without any of those, and too much can kill you.
The thing about fracking is that those chemicals are supposed to be and remain sequestered from potable water aquifers. Ordinarily, that is done as a matter of course, provided the well construction is correct and no one spills any on the ground.
In the event of a mishap, the chemicals involved should be available to anyone doing the cleanup or remediation. Publishing them wholesale, though would be like asking the above mentioned commercial ventures to release their recipes--something the particular company has expended a lot of research time and money on would be made available to their competitors, gratis.
(No wonder there is resistance to just ponying up a list.)
It isn't some huge conspiracy, because those chemicals will only see the light of day again (if ever--some break down in the wellbore) as a component of production fluid, either refined, or disposed of in injection wells far below aquifers which people get drinking water from.
