Grapefruit Seed Extract - Grapefruit Seed Extract (commonly referred to as GSE) is normally used as an antioxidant to help prevent rancidity in lotion and lotion bars. Thick and golden like honey, our GSE is 60% extract and 40% Glycerin. Recommended usage is .5% to 1% by weight. There is some belief that GSE also works as a preservative. At Bramble Berry, we do not endorse the use of GSE as the sole preservative. We believe that a full-spectrum preservative such as Optiphen, Phenonip or Germaben II must be used to truly prevent mold and bacterial growth in your lotion products.
NOTE: GSE is not approved as a food additive or for human consumption by the FDA. In addition you cannot make any microbial or therapeutic claims in products based on the addition of Grapefruit Seed Extract. Please note that this is true of any Grapefruit Seed Extract sold in the US.
