Hi DeAnna,

Thanks for writing.

How do I know if an all natural product needs a preservative for retail?
If a product contains water there is a very good chance that it will grow microbes. Always do a CTFA challenge test for any unique product that you make and an inexpensive plate test for variations.

Is there a safe all natural preservative?
pH can be adjusted, sugar or salt or soap at 20% or more concentration kills germs.

Do you know of any online classes for all natural skin care products?
Do not sorry!

Would a Pure Aloe Vera Gel product need a preservative?
Yes – typically potassium sorbate is used.

Best!
