FAQ Glycerin


USG-small.png   Technical Grade?   USP Grade?    Kosher?    

What does it all mean?


All of the Glycerin that we refine comes from Crude Glycerin shipped to us from various Mid-Western States.  Crude glycerin contains a significant amount of methanol, water, soaps, and salts and typically has a glycerol content of anywhere between 40 to 88%. Crude glycerol is a natural by-product produced during many chemical production process like soap making or Bio-diesel refining, specifically taking place during transesterification of the vegetable fats.


Buyer Beware:

Be leery of any company claiming to produce USP Grade glycerin, or Kosher USP as these companies MUST be registered and controlled by the FDA. Many companies make false claims of producing USP grade glycerin when in fact, they cannot and should not make such claims without being governed by the Federal Government.  As most of the "cheap" glycerin available on the internet is usually imported from Asian countries with questionable quality standards - many stores simply repackage the material and call it USP or Kosher without ever testing the material or verifying the certifications - which is selling outside of FDA control and regulation.

 If you require USP or Kosher and question the source that you're buying from - call for copies of the FDA tracking number/registration and Kosher certificates.

Technical Grade Glycerin - Technical grade glycerin is a refined, high-purity product that is water white with most of its contaminants completely removed. Technical grade glycerin contains no methanol, soaps, salts, and other foreign matter. This is the most common type of Glycerol - used in almost all applications. Unless you need USP or Kosher Grade for the FDA & Kosher Certifications, this is likely the grade that you will want to use.

Our Technical Grade is purer than most available, and in fact usually meets USP requirements.


USP Grade GlycerinUSP Grade Glycerin is a pharmaceutical grade glycerin suitable for food, personal care, cosmetics, pharmaceuticals, and other specialty applications. All of these products have met the US Pharmacopeia specifications (USP 30).  The designation of USP does not mean the Glycerin source crude material is Vegetable of origin, simply that it meets or exceeds the measurable characteristics for purity as required by the USP monograph.  tube1.jpg

To be called USP Grade Glycerin, companies are closely regulated with regards to their manufacturing facility, testing methods, inspections, distribution, and warehousing. True USP Grade Glycerin follows strict rules and guidelines set forth by the FDA. The FDA requires that all domestic companies distributing USP Grade Glycerin must be registered and listed unless they qualify for exemption.

The same applies for USP Glycerin originating from a foreign manufacturing facility going to an importer in the states. In this instance, FDA compliance by both parties is still a requirement. FDA regulations also require systematic and complete record keeping by all USP glycerin manufacturers. They must have supporting documentation at all times for every shipment providing lot numbers and permits tracing back to the plant it was produced in.

USP Grade Glycerin assures buyers of the product's integrity which cannot be achieved through physical and chemical testing alone. On the flip side, Technical Grade Glycerin is not subject to such governmental regulatory control. Although produced by similar processes, Technical Grade Glycerin does not need to comply with USP and FCC requirements or FDA regulations. This grade of glycerin only needs to conform to the specifications mutually agreed upon by the buyer and seller.


Kosher USP Grade Glycerin - USP Grade Glycerin that has been Certified as Kosher.  When a product or establishment is certified Kosher, it means that the product & company comply with a strict policy of kosher food laws, including cleanliness, purity and quality which is controlled an audited annually.

But kosher means more than responsible product preparation. Kosher refers to a set of intricate biblical laws that detail the types of food that a Jewish person may eat and the ways in which it may be prepared.

To be certified Kosher, all ingredients in every product—and the process of preparing the product—must be certified for kosher-compliance too.  A company must obtain certification from a reliable kosher certifying agency. The role of kosher certification and supervision is to check the source of all ingredients, provide for the kosher status of any equipment used to process the product, and to set up a system by which the integrity of both ingredients and equipment is monitored and maintained. The certification agency will also determine if the product contains dairy ingredients or is produced on equipment used for dairy products, so as to alert the consumer and preclude unintentional mixing of meat and dairy. A quality kosher certifying organization is staffed by rabbinically ordained supervisors who have years of education and experience and are able to deal with questions and problems in the facility as they arise.
