The FO %

[Ashlie K]

Hi

I lost my notes on how to determine the Fragrance oil retention in waxes.

Can anyone help me on this, please?

Thanks

Or this? (this was the notes I had been looking for and found a week later

If your finished container needs 11oz. (weight, not volume) to fill, and you use, say 8% FO/lb (notice I'm not using the simple 1 oz/lb ratio), then you would:

Divide your 11 0z. by 1.08 (the .08 representing the %. If using 6% it would be 1.06, etc.). The result is 10.19...that's how much wax you need. Then multiply that 10.19 by 8% (.08 ) and that's how much FO you need, or .81oz. The total of the two is your 11oz., no leftover.

Obviously, some will be lost simply from residue left in your pour pot, so I always calculate my finished weight with a couple tenths of an ounce extra.

This way, I get exactly the amount of wax I need, w/o a bunch of leftovers.
