nice thread, give me some more!
I know there is another chemical that is usually mentioned with Butyl that is frowned upon by some, what is it called and why is it "bad"?
Oh man I don't know.
There are lots of chemicals that are controversial. Phosphates make detergents great cleaners and they really help soften water, but they feed algae and cyano bacteria that grow in our waterways. They upset the balance of ecology in plants, making weeds grow out of control and in the process stifle other plants. They also poison the soil and groundwater.
Alcohols disolve fats and oils and make water based cleaners dry faster. They kill germs and help sanitise. They obviously have flammable fumes and the fumes if very concentrated destroy brain tissue.
Formaldehyde cleans and sterilises well. It breaks up fats in a similar way to alcohol but direct physical contact, or inhalation of the fumes is carcinogenic.
Ammonia is a strong alkaline and is great at cleaning glass and hard surfaces, it also dissolves greasy soils. But the fumes are very irritating and cause asthmatic reactions in some people. Furthermore if cleaners containing ammonia are accidentally mixed with chlorine bleach then a green poisonous gas is produced. This is mustard gas and was used as a chemical weapon in the First World War.
Chems are good and bad. Learn about them and use them with thought and care. That's all you can do.
