if it makes it any easier this is a simple formula you can use...
say you want to make an 8oz jar...
if you need 10%... you would put into a calculator
8(oz) x .10 = .8... or .8oz
if you need 5%.. you put in
8 x .05 = .4.... make sense?
so on this recipe...
if you wanted to make... say... 10oz (283 grams)... you're looking at:10% emulsifying wax (e-wax, Polawax, or BTMS)
10% cetyl alcohol or stearic acid (5% cetyl and 5% stearic is very nice)
10% cocoa butter (or other really hard butter)
10% shea or mango butter (or quite soft butter - shea aloe would be great here)
56% oil - I'm using soy bean oil here
1% Vitamin E
2% fragrance or essential oil*
1oz ewax (28.3)
1oz stearic (28.3)
1oz cocoa butter (28.3)
1oz shea butter (28.3)
5.6oz oil (158.5)
.01 vitamin e (2.83)
.02 fo (5.66)
.01 phenonip (2.83)
... now, when I'm working with a recipe thats less than 2 lbs, I prefer to work in grams.. because how the heck are you going to measure .01oz, u know? SO... there are 28.3 grams in an ounce. So.. for this recipe, in BOLD you will see the grams. Most good scales come with grams and its WAY more accurate when you are working in small amounts.
Thats really all you need to know to calculate any recipe.
16oz in a pound... so 452.8 grams in a pound
28.3 grams in an ounce...
and any percentage when you are trying to find it is just the base number of the batch.... like 10oz... times the percentage you need... .05% for 5%... .10% for 10%.
