Transferring Percents to Grams Easily....

All formulas need to add up to 100%

We write in formulas to make sure all of our ingredients are being used at safe amounts. Formulas also make it super easy to scale up or down our recipes.

If you want to make a 100 gram batch and your recipe calls for 5% glycerin. Then you need 5 grams of glycerin. No math is required for 100 gram batches!

So if you don’t have a formula calculator and don’t want to do the math, or you don't have internet to google it, you can make 100 gram batches with no math needed. Then if you want to make a 200 gram batch, just double it. A 300 gram batch, triple it. Makes it so easy!

If you have 20 (4 ounces) bottles you want to fill, then first google

"how many grams are in 4 ounces?" google will tell you = 113.398 grams

Round this number up to 150. I always round up. Most jars and bottles will actually fit more product than it says, or sometimes they fit less, just depends on how dense your product is. Something more fluid (liquidy like water) like a toner will probably fill a 4 oz bottle perfectly to 115 grams, but as for a thick gelled face wash, you might be able to fit 130 grams of it in your bottle. This is because the product is more dense and it weighs more by volume. So this is why I always make more product than I think I need. Also some of the product just goes away from testing the pH, getting stuck to the side of the beakers or spoons or stirring rods.

Just because you make a 500 gram batch, doesn't mean you will end up with exactly 500 grams of product. Some of the lotion gets stuck on the immersion blender, you can't always scrape your beakers perfectly clean, you have to check and adjust the pH. Always make more product than you think you need.

Back to our equation above. We are rounding 113.398 grams to 150 grams. So if we have 20 bottles that can fit "150 grams of product" we need to multiple 20 x 150 = 3,000

So if you have 20 (4 ounces) bottles you want to fill, I would personally make a 3,000 gram batch.
