I plan on using preservatives in my scrubs and certainly any product with water. My question is this: What is the best percentage of preservative to total volume of the product? Each recipe is different, and I want to come up with my own recipes for products, but am not sure about how much preservative I should use. I assume it will change with each recipe...Can anyone offer advice? Thanks! Leigh

Each preservative has a recommended usage rate so you'll need to go by whatever that is. 1% of one brand preservative might be fine, but for another, it may be way over the recommended use rate. Your supplier should be able to provide you with the correct rate. :D

If the preservative should be used at 1%, then you would use it as 1% of whatever recipe you make. There's a sticky note on one of the boards that gives a list of preservatives and their best uses.

You will need to research each one individually. They are used at different rates and some are temp sensitive or pH sensitive.

Thank you very much! I had sort of thought the usage would be on the bottles, but it isn't so I'll start the research.
