Ok, I wouldn't use that stuff. Unless you know what the ingredients are, you don't want to add that to the aquarium. It also says it is bad for our eyes so putting it into an aquarium with fish, even though it will be diluted, isn't something I would do.
Take the product back to where you got it and get a refund.
Write to the government and tell them there are products being sold with no ingredients listed. That stuff could contain absolutely anything including illegal drugs, antibiotics, carcinogenic substances, etc. Without an ingredients list you have no idea what is in that and whether it's safe for you, your fish, or to end up in the waterway where most aquarium water ends up.
