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.

Certificate of Analysis (CofA) and Safety Data Sheet (SDS). We publish on our website those documents for most of our products, some products don't provide either because the product doesn't require it. 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.

BULK ITEMS: When a customer adds a bulk item to the cart, the customer’s immediately shown on the screen how many number of days should be allowed for the bulk product to arrive at our warehouse. If the bulk item happens to be in stock, we’ll ship sooner than the customer would expect. As we emerge from Covid, logistics operations are not yet back to normal, what used to arrive at our warehouse in 3 days now takes much longer. Should a vendor inform us the ordered product will take longer than what’s mentioned on our website we’ll email the customer with the latest information.
EO = essential oil
FO = fragrance oil
HOW PRODUCTS ARE DISPENSED...
Essential oils: in 1/32 oz. to 1/4 oz...amber glass vials with orifice reducers. ½ oz. to 2 oz...in amber glass bottles with white caps and Eurodroppers...3 to 4 oz. in amber glass bottles with black caps and without orifice reducers...7 oz. in aluminum bottles...15 oz. in amber glass bottles with black caps...10 & 25 lbs. in HDPE plastic containers with wide mouths although, occasionally, 25 lbs. may be dispensed in factory-issued metal containers with pouring spouts.
28 lbs. of carrier oils and other liquids are dispensed in individual HDPE plastic gallon containers with handles, each holds the purchased net weight of liquid.
30+ lbs. of carrier oils, other liquids, soft butters, Castile gel and other products are dispensed in plastic HDPE pails w/metal handles & pouring spouts in the lid; those products may remain inside the pails indefinitely when properly stored. After Covid, we reserve the right to use any packaging/dispensing container available to us and not mentioned above because it continues to be difficult many times to restock the same packaging container or material used in the past.
NOTE: An EO may safely remain inside an aluminum container for up to 3 months, but if storing longer than 3 months the oil should be transferred to amber glass. Fragrances and carrier oils up to 8 lbs. may remain inside HDPE plastic bottles indefinitely. If the customer at any time feels more comfortable transferring a product to glass this should be done. ALL PRODUCTS ARE DISPENSED BY WEIGHT, THUS, SOME CONTAINERS MAY BE FILLED HIGHER THAN OTHERS DEPENDING ON THE WEIGHT AND VISCOSITY OF EACH PRODUCT.
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.
HOW TO STORE: EOs, FOs and BUTTERS should be stored in tightly-sealed containers away from direct light and heat. Some EOs could be highly flammable, keep away from open flames. Keep all liquids and powders you purchase from Camden-Grey tightly capped and away from the reach of children, the elderly or infirm and pets. Refrigerating butters could adversely affect the consistency of the butter, please join our Forum if you need to learn how to handle, work with and store products.
