When to use a preservative, and which one to use?

I'm getting some FBB from the co-op order, and I'm excited about trying my hand at scrubs. When do I need to use a preservative, and how do I figure out which one to use?

I started with Liquipar in my scrubs and have kept at it. It works for me. You should always use a preservative on anything that will come in contact with water or could be contaminated.

FBB already has a preservative in it.

I didn't think that it did. I don't see it in the INCI here from Kangaroo Blue and she suggests preservative.

INCI: Glycerin, Distilled Water, Sodium Cocoyl Isethionate, Sorbitol, Propylene Glycol, Disodium Lauryl Sulfosuccinate, Stearic Acid, Sodium Chloride, Pentasodium Pentetate, Tetrasodium Etidronate.

Here's a simple recipe that can be easily adapted into your own creations! Click here for pictorial.

40 oz. FBB

2 oz. Apricot Kernel Oil

2 cup of brown sugar

1 oz. of Pink Sugar

few drops of red colorant

Liquapar Optima Preservative

I was looking at the one from The Chemistry Store, theirs has:

INCI: Distilled Water, Glycerin, Sorbitol, Sodium Cocoyl Isethionate, Disodium Lauryl Sulfosuccinate, Sodium Chloride, Propylene Glycol, Phenoxyethanol, Methylparaben, Ethylparaben, Propylparaben, Butylparaben, Isobutylparaben, Tetrasodium EDTA.

Cool. When this first came out there weren't any preservatives in their, but maybe the formula has changed.

I know, I went and looked at my tub and saw that it didn't come with a preservative so I had to do a double take on their website and thought I was reading the ingredients for something else. lol I wonder though if you add more oils etc to their fbb, wouldn't you have to count for the extra oils added in and add more preservative?
