![]() In this same section where you're at now, look to the tab to the left titled Documents, click on it and that's where you'll find either document for the product you seek.

Shelf life: 7-9 years, stored away from light and heat, kept in a cool place tightly sealed, not in steel or metal containers, store only in plastic or glass. Color: Lemon yellow to golden brown liquid, may vary from batch to batch. INCI: Grapefruit Seed Extract (Citrus grandis). Inert Ingredients: Glycerin (USP 97.7 and kosher) 38.22%, Moisture 1.78% (max). If used all by itself as the only preservative, it won't be potent enough or broad-spectrum enough to cover every contingency.Īctive Ingredients: Grapefruit Seed Extract 42.72%, Vitamin C (Ascorbic acid) 17.28% (max., primary source of Vitamin C is from the extract). It needs to be used as an antioxidant or as an add-on with another preservative. ![]() GSE should not be expected to prevent mold when used by itself. It really should be combined with a broad spectrum commercial preservative in items for sale and the items should be challenge-tested in a lab to make sure the preservative system is sufficient and effective under a range of conditions, including heat, exposure to light and over a normal shelf life of maybe a year or so. It can be an effective preservative, but it is neither as potent or as broad spectrum as commercial preservatives like Optiphen or Germaben, etc. It's a good antioxidant, like ROE or T-50. Using as little as 0.05% (one ounce in 16 gallons), soaps could retain color, aroma, and appearance for extended periods (one soapmaker reports having bars that are three years old and they look and smell as fresh as day one).Ĭitrus essential oils/GSE are noted for their anti microbial properties and some customers "swear by" products made with GSE, especially when traveling and during cold and flu season. GSE will greatly extend the shelf-life of hand-crafted soaps. Products that contain as little as 0.1 percent GSE have an indefinite shelf life. To measure, multiply the total volume (in ounces) of your batch times. Usual recommendation is 2% for most applications. ![]() The range of ascorbic acid percentages range typically from 14-18%. ![]() Additionally there is ascorbic acid (or Vitamin C), that is present in the extract and is also added as an active component. The primary active component is the grapefruit seed extract itself which contains several bioflavonoids, primarily naringin, that contribute to the efficacy. Our Grapefruit Seed Extract consists of 60% active and 40% inactive ingredients. ![]() Sold by weight for cosmetic applications, not for internal consumption. SOME CUSTOMERS WHO HAVE POSITIVELY REVIEWED THIS PRODUCT ERRONEOUSLY CONSIDER GSE A PRESERVATIVE. PLEASE READ THIS FULL DESCRIPTION IF YOU ARE UNDER THE IMPRESSION GSE IS A PRESERVATIVE BY ITSELF. THIS IS NOT A PRESERVATIVE, IT’S AN ANTI-OXIDANT. ![]()
