Last week, I took a phone call from a customer looking for Grapefruit Seed Extract. She wanted to use the Grapefruit Seed Extract as a preservative in her lotion. I’ve done some research in the past about Grapefruit Seed Extract and I have discovered that it has little preservative abilities. After I explained to the caller that a preservative is different than an antioxidant, I thought it might be a good idea to share information on the differences between preservatives and antioxidants.
An antioxidant helps slow down the oxidation of any substance that will be damaged by exposure to oxygen.
A preservative acts by preventing the growth of yeast, bacteria and mold. Preservatives are desirable to keep our creams and lotions from becoming walking Petri dishes.
I hope this helps!
