| Grapefruit seed extract (GSE)
Odor: characteristic Use: 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). |
