I dream of closed, self-sufficient systems. A few weeks ago, I visited the London Permaculture Festival as I'm very, very interested in permaculture. There, Hendon Soap had a stand. They were selling a DIY Lip Balm Kit.
I use lip balm regularly, so it occurred to me I ought to learn about how it's made, and maybe make my own in the long run! Today I tried my hand at making it. It's not as easy as it looks! In theory you toss everything into a sauce pan, put in 60g of oil (I used vegetable oil), and once everything is melted, you put it in the tins and put those in the freezer as fast as possible so they cool rapidly (this is to avoid a grainy texture). In theory you can also add some edible essential oils if you want a scent.
Long story short: I made a huge mess. And the stuff is quite difficult to clean. I managed to do one tin approximately right.
The rest I was mostly able to salvage and store in a little jar. When I finish that first tin, I'll re-melt that and maybe this time use a little pot with a pouring tip to avoid spilling, as well as some kind of tool for moving the very hot tins into the freezer properly! It was so hot it melted the ice in my freezer away entirely, creating a nice little indentation to hold it.
Please don't judge the ungodly amount of ice cream -- there's a heatwave coming!
