I would suggest that if toxicity reduction this year is your goal, instead of saying the individual chemicals in a formulation or product must have below a certain toxicity per gram, rather say the formulation has to have less than a certain toxicity. If someone's changing from that surfactant that's a bit more toxic but far more effective so that less is being used, you would get credit for that in terms of your overall formulation being a lot less damaging to the environment. If you regulate chemicals individually per gram of the chemical rather than per gram of the formulation, then that surfactant that would give such a big green improvement would not be allowed.
