As far as I can tell there is at least no formaldehyde in it.
Most of the blue products I viewed in a quick internet scan appears to be 25% formaldehyde.
I have no idea how that is even still legal these days, especially for a product that is absolutely not required or necessary in any way, shape of form: bio is always better.
It reminds me of Victorians using arsenic in gardening and as a dye back in the day
Fluoride toothpaste incidentally won't be helping any septic tanks either as some of the fluorides chosen are quite deadly, for instance IIRC sodium fluoride being 80x more lethal than calcium fluoride.
