You don't need anything fancy, regular PP is chemically resistant to most corrosive chemicals. The main issue is not resistance, but that if the walls of your container are thin, chemicals you put inside might leak out.
Working in hospitality you'll bang your head against the wall convincing some clown their super special bleach based cocktail is a coshh and health nightmare
Honestly if you want to get access to dangerous shit, you needn’t go farther than gasoline. Dissolve syrofoam until saturation to make napalm, or combine with ammonium nitrate, and insert a blank to make an ANFO bomb.
Gasoline and Styrofoam doesn't create the substance Napalm, as the chemical combination lacks naphthene or palmitate. Napalm is just the broader term that the US Army applies to Weaponized Jellied Gasoline, which was petrol + benzene (already in gasoline) + polystyrene.
To make true original napalm (which was used up until Vietnam) you would need aluminum soap powder of napthenic and palmitic acids, hence (NA-PALM), that is the stuff that was originally in flamethrowers and incendiary bombs.
Most household varieties of hydrogen peroxide and vinegar aren't concentrated/strong enough to make paracetic acid. You'd need vinegar of a much higher than 6% concentration typically sold and ideally higher concentration peroxide than the drug store kind (like the kind you could get for industrial applications without a special permit). Not that you should mix household cleaners without a clear understanding of the chemistry but I'm just doubtful this is a risk for most people who don't have access to commercial strength varieties of both.
Bleach and toiletbowl cleaner is way more dangerous than I thought, glad I never did that, I probably would’ve done it as a kid if left to clean the toilet by myself
