Dr. Bronner's Peppermint Soap

Dr. Bronner's peppermint soap has that dense blue label covered in tiny text about moral philosophy and cosmic unity and the first time I read it in the shower I spent 20 minutes trying to follow the argument. Probably the longest I've ever spent thinking about anything while standing under running water. Soap this concentrated produces more lather from a quarter-sized amount than you'd expect. Peppermint oil gives a tingling cold sensation on your skin that wakes you up unlike coffee quite match. I started buying the 32-ounce bottle because it lasts an entire semester and the price per use works out to something absurd like 3 cents a shower. It is the calculation I run when trying to justify not buying the fancy body wash my roommate uses. The bottle has been in production since 1948 and the formula has barely changed. Meaning the company figured out the ratio of castile soap to essential oil 75 years ago and decided that was good enough. Everyone in the outdoor club uses it because you can wash dishes with it and brush your teeth with it and do laundry with it. The fact that a single product handles all of those tasks makes packing for camping trips significantly easier. Labeling claims you should dilute it but nobody actually does and it works fine either way. I keep mine on the shelf next to shampoo bottles that cost 4 times as much per ounce and do one thing.
