Grapefruit seed extract (GSE), Bulk
THIS IS NOT A PRESERVATIVE, IT’S AN ANTI-OXIDANT. PLEASE READ THIS FULL DESCRIPTION IF YOU ARE UNDER THE IMPRESSION GSE IS A PRESERVATIVE BY ITSELF. SOME CUSTOMERS WHO HAVE POSITIVELY REVIEWED THIS PRODUCT ERRONEOUSLY CONSIDER GSE A PRESERVATIVE.
Sold by weight for cosmetic applications, not for internal consumption. Our Grapefruit Seed Extract consists of 60% active and 40% inactive ingredients. The primary active component is the grapefruit seed extract itself which contains several bioflavonoids, primarily naringin, that contribute to the efficacy. Additionally there is ascorbic acid (or Vitamin C), that is present in the extract and is also added as an active component. The range of ascorbic acid percentages range typically from 14-18%.
Use GSE at a rate of .5-5%. Usual recommendation is 2% for most applications. To measure, multiply the total volume (in ounces) of your batch times .02 to get the ounces of GSE to use.
Products that contain as little as 0.1 percent GSE have an indefinite shelf life. GSE will greatly extend the shelf-life of hand-crafted soaps. 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).
Citrus 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.
It's a good antioxidant, like ROE or T-50. 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 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.
GSE should not be expected to prevent mold when used by itself. It needs to be used as an antioxidant or as an add-on with another preservative. If used all by itself as the only preservative, it won't be potent enough or broad-spectrum enough to cover every contingency.

OUT OF STOCK ISSUES: If a customer orders a large quantity of a product and all of the product is not in stock when the order is entered into our system, once the new stock arrives we will ship separately whatever quantity we may owe the customer. Most of our restocking orders arrive at our warehouse 5-7 business days after we place a restocking order, sometimes sooner. Should the distiller or vendor inform us restocking will take longer than 7 business days, we’ll promptly notify the customer.
Please note that we do not allow order cancellations for any reason and we don’t allow removal/cancellations of products which become partially or completely out of stock after the customer places an order.
Raw materials/ingredients are dispensed by weight. Many customers ask how many ounces in a pound, there are 16 ounces in one pound. These are not fluid ounces, they are ounces by weight.
EO = essential oil
FO = fragrance oil
Our containers are filled with products to where our commercial digital scales indicate the container should be filled. Some containers will be filled to the top, some will not.
HOW OILS ARE DISPENSED: All our products are dispensed by weight. EO's in 8 oz. through 2 lbs. - amber plastic pharmaceutical-grade bottle. EO's in 5 and 10 lbs. - heavy duty plastic container w/pouring spout, the oil may remain inside the container at least 2 months. EO's in sizes of 25+ lbs. - industry-standard metal or plastic can with a pouring spout, the oil may remain inside the metal can indefinitely and up to 2 months in the plastic pail. It's our decision in which type of pail we dispense the product, metal cans are not readily available. CARRIER OILS - plastic bottles/pails depending on the size ordered, do not need to be transferred to glass unless you wish to do so. FO's - in plastic containers, contents do not need to be transferred to glass unless you wish to do so.
Essential oils in sizes from ½ oz. to 4 oz. are dispensed in amber glass bottles without orifice reducers or glass droppers. If we ever run out of amber glass bottles, we reserve the right to use any other glass bottle available at that time. The only sizes of EO's dispensed with orifice reducers are 1/32, 1/16, 1/8 and 1/4 oz. sizes. If you require bottles/vials with orifice reducers or Eurodroppers, we sell those separately.
HOW TO STORE: Upon receipt, EO's dispensed in plastic bottles MUST be transferred into amber glass bottles. EO's, FO's and BUTTERS should be stored in tightly-sealed containers away from direct light and heat. Many oils could be highly flammable, keep away from open flames. Refrigerating butters could adversely affect the consistency of the butter, please join our Forum if you need to learn how to handle and store products.
