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.

I couldn't believe it, this extract diluted with green tea lighten my age spots, minimized the pores, specially around my nose. Just be careful it's very potent. Too much of it will dry your skin. Dilute properly. Can't wait until all my age spots are gone. It's also great for pimples.

These are very easy to use and great quality.

I purchased a small 1/8 lb of this to sample before commiting to a much larger quantity. I'm very pleased with the quality and packaging, I'll be ordering in bulk. GSE is a must in all my CP soaps...

I used a combination of GSE and ROE long before they were approved for use as preservatives, with wonderful results. I like all natural products and GSE helps keep them that way. I do not use man-made chemicals in any of my products I sell.

HOW PRODUCTS ARE DISPENSED...
BOTTLING/PACKAGING:
Essential oils: Are sold only in the quantities/net weights listed on our website. These oils are shipped to us by the distiller or manufacturer in industry-standard metal or plastic containers and that’s how we ship them to you.
Carrier oils and most other liquids are dispensed in individual HDPE plastic pails or containers with some type of handle, each container holds the purchased net weight of liquid.
Soft butters such as Horsetail and Almond are dispensed in plastic HDPE pails w/metal handles; those butters may remain inside the pails indefinitely when properly stored. Hard butters such as Cocoa are dispensed factory-wrapped in plastic and placed inside a box. Castile Gel is dispensed in a self-contained cubitainer with pouring spout.
NOTE: While the packaging methods mentioned above are generalized, we reserve the right to dispense and ship in any available container. If a customer at any time feels more comfortable transferring an essential or carrier oil to glass, this should be done.
Raw materials/ingredients are sold and dispensed by weight. Many customers ask how many ounces are 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 and FOs could be highly flammable, keep away from open flames and from varnished or wood surfaces. 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 a butter, please join our Forum if you need to learn how to handle, work with and store products.
