I've seen tea tree oil been advertized as powerful anti-fungal & anti-bacterial agent, which people seem to use for practically anything:
- laundry (in particular cloth diapers)
- room freshener
- bathroom cleaner
- insect deterrent
I can attest that tea tree oil really works wonders. Old T-shirts (5+ years) that have become smelly even after washing and sun-drying smell like new (2-3 drops in the washing); bathroom mold disappears; fleas (I live next to a cow pasture) leave never to return.
I recently bought a bottle of tea tree oil in Germany. On the bottle it says
Umweltgefährlich (pollutant) and Xn Gesundheitsschädlich (health hazard).
Xn basically means "don't ingest", but concerning the "pollutant" label, I seriously wonder what exactly the effects are and why it is being advertised by manufacturers as a natural alternative to chemical solutions.
(I don't customarily use chemical cleaners, so I don't know, but it might just say the same thing for other "conventional" products...?)
Is there any information on how detrimental using tea tree oil is to the environment?
As a bonus question, my waste water is "bio-digested" on-site. What would be the effects of 2-3 drops of tea tree oil per day (diluted in hundreds of litres of grey water) on the anaerobic tank and on the ground water?
