Item Safety check

[KiwiTraveler]

Hi all
I am currently gathering the materials to do my first extraction and have purchased a 250ml bottle of 'Ph Down' Phosphoric acid, its 81% V/V

I checked the MSDS and it said 81% phosphoric acid and 9% water leaving an unknown 10%, maybe im reading it wrong and im pretty sure its safe but someone with more experience may be able to tell me if its really a safe product.

Here is the Safety Sheet

The quantity of acid you need for an extraction is pretty small, and therefor, any 10% fraction of filler in the phosphoric acid is going to be pretty miniscule and should probably be just fine to use, especially if the 'Ph Down' Phosphoric acid is used for hydroponics.
