Salty Toothpaste: The May Challenge

The next step on my ‘reducing plastic’ journey was to replace my empty toothpaste tube with homemade toothpaste.  After doing loads of research online, I went out expecting my task to be easy. I mean, most of the recipes I could find online for homemade toothpaste only had two basic ingredients: Coconut oil (which I already had) and baking soda.  I went to my local supermarket  to get the baking soda.

Only to find that…I couldn’t find baking soda. It then occurred to me that I had no idea what baking soda was called in Japanese nor where to find it in the supermarket.  After a quick search in the dictionary on my phone, I found the name of it (重曹–pronounced ‘juusou’) and looked around in the baking section for it.  It was nowhere to be found. Eventually, I asked an employee where it was.  

She actually didn’t know where it was either! She had to ask someone, who then took us both to the salt/vinegar/sauces aisle.  It was a tiny blue box on the top shelf (by ‘tiny’ I mean 7 cm x 9cm x 1 cm max size…in the US the boxes are at least twice that size).  The tiny box cost about $3.50! I was upset, but bought it anyway because it would speed me on my plastic-free journey.  I mean, you can get a 5 pound bag online for the same price!

 

When I finally got home, I decided to use this recipe.  I hadn’t been able to find the essential oils, but thought nothing of it because ‘meh, it is just for taste and how bad can it be??’  Well, I was disappointed for a couple reasons. First, the whole point of making my own toothpaste was to reduce my waste, but when I opened up the box of baking soda–true to nearly all Japanese products–the baking soda was all inside a plastic bag inside of the box.  The second reason why I was upset was because of the taste. Without the oil drops, all I could taste was the saltiness of the baking soda. This toothpaste was SO SALTY! Like, crying-tears-of-loneliness-that-drip-into-instant-cup-noodles-on-Saturday-night level salty!

Holy mother of margaritas, I was not prepared the first time.  True to my ‘reducing waste’ policy, I used up the full amount (which, thankfully, I had only prepared a small amount as a tester).  The time it took me to finish it up allowed for my peppermint oil to arrive. Even with the peppermint oil, it is still a bit salty, so if you are sensitive to salty things, you can add a bit of stevia to your toothpaste.  Thankfully, baking soda and coconut oil are both really easy to find in Korea, so this part of my life is much easier!
