Teach Soap

Hi there, I've started making salt and sugar scrubs (just for me so far) but I know if I sell them I'll have to add a preservative. In reading through this forum it seems that Phenonip might be the best bet for my scrubs that are just basically olive oil, salt or sugar, and EO or FO. BB says that phenonip should be .5-1% of the total, but I am really, really, REALLY bad at math. Help! If I'm making a 16oz container of scrub, how much phenonip? One drop? Two? Seven?

And speaking of containers, would acrylic containers work for scrubs? Or would the oil break down the container or make it cloudy? And would the container hold onto the scent afterwards? I'm looking for containers I can reuse.

Thank you so much for your help!

You really should get an accurate scale. If you don't use enough preservative it can grow mold, germs and bacteria. Use too much and it can irritate the skin. For 16 ozs. of a scrub at 0.5% of preservative, you will need 0.08 oz. of Phenonip. 20 drops is about 0.031 oz. 40 drops is 0.062 oz. So a rough estimate for 16 ozs. of a scrub would be about 60 drops.

Acrylic containers won't work for scrubs as over time they will crack.

Thank you for the measurements, that helps a lot. As for the containers, if acrylic doesn't last, do you have any information about what does?

I added some Optiphen to my whipped sugar scrub, and I used a 4oz PET jar. Now when I open the jar, the top of the scrub smells "skunky". Did I use too much of the preservative? Or could it be the jar that smells funky?
