What does the UPS mean?
The abbreviation USP stands for United States Pharmacopeia, a document first published in 1820 by the Medical Society of New York State. Recognized as official by Congress in 1848, this document was used as a standard reference by physicians for prescribing medicines.
Today, the USP includes chemical descriptions, identifying tests, and purity tests, primarily for active ingredients. All materials listed in the USP are considered drugs by law and subject to all the U.S. Food & Drug Administration
requirements pertaining to drugs. Labeling a product or a substance as USP implies that it conforms to all the legal requirements of the FDA and that it was produced in accordance with the principles outlined in FDA’s Good Manufacturing Practices (GMP).
What differentiates USP and food-grade glycerin from technical grade glycerin?
Glycerin USP is closely regulated by the FDA in all aspects of manufacturing, testing, inspection, distribution, and warehousing. Glycerin USP is subject to FDA rules requiring registration and listing, and glycerin FCC as well as USP are also subject to Good Manufacturing Practices, a series of appropriate procedures prescribed by FDA, while the technical grade is not under such regulatory control. FDA requires all domestic owners or operators of all establishments that manufacture or process glycerin USP to register and list, unless specifically exempted (21CFR §207.20).
For glycerin USP of foreign origin, the foreign manufacturer and the importer share the responsibility of FDA compliance (21CFR§207.4). The Agency’s definition of "manufacturer" includes the original producer as well as re-packagers and/or distributors(21CFR§207.4). Additional information on drug registration and listing instructions is available from the FDA
. Further, under FDA regulations, the quality and purity of USP and FCC glycerin products must be supported by systematic and complete record keeping on the part of the manufacturer. For example, every shipment of USP and FCC glycerin must be referenced to a lot number, which permits tracing back to the plant in which the product was produced. These requirements are designed to assure a level of product integrity that cannot be achieved strictly by reliance only on physical and chemical testing.
Technical grades of glycerin, on the other hand, are not subject to the same FDA regulatory oversight. Although produced by similar processes, the technical grades of glycerin do not have to comply with USP and FCC requirements or with FDA regulations. This quality grade of glycerin must conform only to the specifications and terms agreed upon in the transaction between buyer and seller.
What are the uses of glycerin UPS?
Glycerin, whether recovered from triglycerides or synthesized, is principally used as a highly refined and purified product, with a very high concentration of glycerol. Glycerol
, the main component of glycerin, has the chemical formula C3H5(OH)3. It is a trihydric alcohol, possessing two primary and one secondary hydroxyl groups, which are its potential reaction sites and the basis for glycerin’s versatility as a chemical raw material. For example, glycerol esters, the reaction products of glycerin with various fatty acids form an important class of derivatives that are extensively used in the food industry. The physical properties and characteristics of glycerin are as significant as its chemical properties for many applications. These qualities enable glycerin to be used as a humectant, plasticizer, emollient, thickener, solvent, dispersing medium, lubricant, sweetener, bodying agent, antifreeze
, and processing aid.
