Question on 2 scrub recipes

[Bret]

I found these on MMS. Neither has a preservative. If one were to want to sell these (after testing, of course), how much preservative/what kind would one need to add?

Recipe 1:
.50 lb fine Sea Salt
3 ounces Colorless Jojoba Oil
1 ounces Sunflower Oil
2 ounces Melt and Pour Soap Base
2 ml fragrance oil

Recipe 2:
180 gram white sugar
40 grams brown sugar
90 grams Sunflower Oil
5 grams Liquid Glycerin (not Melt & Pour Soap Base)
10 grams Colorless Jojoba Oil
50 drops fragrance oil

Diffreent preserves are used at diferent artes. I use germaben II in scrubs & it is suggesteed at .3-1% useage rate so here come your math skilss-LOL!

 

[Tabitha]

The 1st recipe is 12oz so .12th of an oz would be 1%(max)

.36 would be .3 of an oz

1oz=6 teaspoons

1 teaspoon =.16th of an oz (a little more than the max you want to use)

1/2 teaspoon = .32 of an oz (the minimum you would want to use)

Someone pleae double check my math... it was my WORST subject in school!

It si much easier to figure uot in larger batches
