Thanks Scott, I sent them an email with some inquiries. I will post their response.

I did locate the msds for isopropyl alcohol here:

Specific info copied from msds:

SECTION 12 ECOLOGICAL INFORMATION



ECOTOXICITY DATA:

fontinalis)



INVERTEBRATE TOXICITY: 3142000 ug/L 48 hour(s) EC20 (Biomass) Ciliate

Protozoa (Tetrahymena thermophila)



ALGAL TOXICITY: 2200 ug/L 96 hour(s) EC50 (Growth) Green algae (Chlorella

pyrenoidosa)



FATE AND TRANSPORT:

BIOCONCENTRATION: 0.38 ug/L 15 hour(s) BCF (Residue) Red swamp crayfish

ENVIRONMENTAL SUMMARY: Highly toxic to aquatic life.

"Forget pounds and ounces, I'm figuring displacement!"

If we accept that: MBG(+)FGSF(=)HBG(F1)
And we surmise that: BG(>)HBG(F1) while GSF(<)HBG(F1)
Would it hold true that: HBG(F1)(+)AM500(x)q.d.(=)1.5lbGRWT?
PB answer: It depends.
