Pros: very concentrated, lasts forever, eco-friendly, socially responsible
Cons: Peppermint is most widely available, but I don't like using it in the shower. I prefer Almond....mmmm.
I use the liquid soap in a refillable foaming soap bottle. I don't have any problems with clogging, spurting, etc. I just reuse the Method brand foaming pump, and add 1-2 tablespoons of soap, then slowly fill the rest up with water. The smallest bottle lasts about a month(And I wash my hands a LOT.)
Also, one reviewer said that they didn't like how much water the liquid soap has in it. In fact, it is still very concentrated, and more eco-friendly to ship, uses less materials to package, etc, than other liquid soaps. The big bottle lasts forever! You really can dilute it down quite a bit, without any loss of quality. Also, when you are diluting it, you can add food coloring...kinda fun. One note though--if you don't use the pump very often, some of the soap may settle, causing "loss of lubricity", as my husband likes to say. Just give it a quick shake, and all is right again.
They also use fair trade oils, not many companies are doing this at prices I can afford, so it is really nice to be able to buy products that are so socially responsible. Also, you should check out how this company treats their employees. They are a model for all businesses.
Oh, and p.s. I tried it as toothpaste. It might work in a pinch, but I wouldn't recommend it.
