Step 2: Ingredients and materials
The following quantity will fit easily into most lip balm tins, but you will have a little left over if you are using a tube, which usually holds only 0.15oz. For the triple lipstick mold, double the recipe.
I have tested a variety of different ingredients, and although the end product varies in "feel" you have a lot of flexibility in your choices.
Here is the basic recipe:
1/2 crayon of your favorite color (approx 2.4g)
1/2 tsp jojoba oil (approx 2 g)
1 almond-sized chunk of shea butter (approx 2g)
Ingredients you can add to the above:
1 pea-sized dab of lanolin (improves feel and possibly color distribution)
1 pinch gum arabic (improves color distribution and durability of color)
1 drop vitamin E (helps prevent oil from becoming rancid, improves shelf life)
1 pinch zinc oxide (makes color lighter and more opaque, offers protection against UVA and UVB sun rays -- but make sure your wax mixture is well stirred before you pour)
You can replace shea butter with cocoa butter (will make lipstick slightly more firm)
You can replace jojoba oil with castor oil (will make a glossier lipstick)
These are the alternate ingredients I've tried, but there's no reason you can't experiment with any other type of edible oils.
