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!
