While our aloe vera fields are 100% certified organic, the end-products are not certified due to the fact that a small percentage of conventional preservatives have been added to most to ensure a shelf-life (unopened).
These preservatives are not on the USDA’s allowable ingredient list for organic products and therefore are considered prohibited. This is true of just about all preservatives that guarantee a measure of APC or Yeast & Mold control.
What some companies have done is add an alternative organic ingredient (perhaps citrus in nature) to function as a preservative. This can work of challenge studies have been performed with this.
