Finally... measuring for Bath & Body products made easy!
We created this chart based on fragrance oils, but also applies to any other additives.
" I get so many questions about how to break down the meausrements into smaller portions that I thought an easy-to-use chart would be really handy. I'm not a math wiz, but I was determined to figure this out for you all! So I spent hours researching, experimenting & calculating this info, and putting it into an organized chart.
I hope it's helpful and makes things a little easier for you :) "

Chart Based on 1 oz per Gallon
(cut these amounts in half for products you only use 1/2 oz per gallon in)

Amount of Bath Base you are making	-	Amount to add in Ounces	Ounces on a digital scale	Approx. Amount in Table Spoons	Approx. Amount in Tea Spoons	Amount in Milliliters	Amount in Grams	Amount in Drops (Based on an average of 23 drops per gram or 115 drops per teaspoon.)
1 Gallon (128 oz.)	add	1 oz.	1	2 Tbsp	6 tsp	29.57	28.35	652
1/2 Gallon (64 oz.)	add	1/2 oz.	.5	1 Tbsp	3 tsp	14.79	14.17	326
32 oz. (1 quart)	add	1/4 oz.	.25	1/2 Tbsp	1 1/2 tsp	7.39	7.09	163
16 oz. (1 pound)	add	1/8 oz.	.125	1/4 Tbsp	3/4 tsp	3.7	3.54	81
8 oz.	add	1/16 oz.	.0625	1/8 Tbsp	3/8 tsp	1.85	1.77	40
4 oz.	add	1/32 oz.	.03125	1/16 Tbsp	3/16 tsp	.925	.885	20

Want to figure out what percentage you're adding when you add an ounce to the gallon?
Take the amount of additive in ounces (1), + the amount of the base (128 oz.) = 129 total ounces.
Now take the additive (1 oz) divided by the total (129 oz) and you get = .00775
Take that number and multiply (x) 100, and that gives you the percentage of .775%,
which is a little over 3/4ths of a percent.

Note: As long as you are adding only 1% or less of an additive (fragrance, soy oil, etc.),
it will not upset the blend or compromise the effectiveness of the preservatives.
Any ingredient with a content of under 1% can be listed on the product label at the bottom
and is not required to be in any specific order as long as they are listed under ingredients
that have contents higher than 1%.

.5 (1/2)% would be .645 ounces (a little over half an ounce)
1% would be 1.29 ounces (a little over an ounce and 1/4)
