Prepare your chapstick containers by ensuring they are completely wound down and twisted firmly as this helps prevent them from leaking out the bottom.
Place all the ingredients, except the vitamin e oil, into your pyrex bowl and place it into a saucepan filled with a few centimetres of hot water that is sitting over a medium-low heat.
Make sure that none of the water from the saucepan gets into your oils.
Gently stir until the ingredients have completely melted into a liquid and combined. Don't leave it sitting on the heat any longer than needed, as you don't want it to get too hot.
Remove the bowl from the saucepan and dry off the water from the outside of the bowl so it doesn’t drip onto your work surface and lip balm.
Add the vitamin E and stir to combine.
Pour your liquid lip balm into the chapstick tubes and then leave them to completely cool and become firm.
As the lip balm cools, it can shrink and retract a little. If you want to, reserve a small amount of the melted lip balm. Wait about 5 minutes as the balm cools and hardens, then top each one up.
