Glycerin

What it is pure or USP Glycerin?

Glycerin is a very important molecule that is used in different fields and areas.

It is also known as glycerol and it is a triol (triol) with a skeleton of 3 carbons, all occupied by a hydroxyl group, hence its name IUPAC: propane-1, 2, 3-triol or 1, 2, 3 propanetriol.

  • CAS Number: 56-81-5
  • EC number: 232-293-8

Origin of Glycerin

liquid glycerineLiquid glycerine is mainly obtained by the hydrolysis of fats and oils using the so-called Fat Splitting method, i.e. a splitting of fats/oils from Colgate-Emery which yields two products: crude glycerine (at a concentration of approximately 12-15%) and the free fatty acid chains.

The traditional method used to obtain the fats and oils from glycerine was through saponification of fats and oils, as if it were a by-product of the production of soap glycerine. The triglyceride reacts with caustic soda to provide soap and glycerine.

Another highly developed and booming method to achieve this is through the transesterification reaction of oils and fats to obtain biodiesel. Oils and fats react with an alcohol (methanol or ethanol) to yield methyl or ethyl esters and glycerin.

However, the last and most modern mechanism to obtain glycerin is related to the progress of the polymer industry derived from propylene, specifically, in the synthesis of epichlorohydrin (precursor of plastic resins, epoxy, exchange, among others).

Properties and applications of pure glycerine

Glycerin is one of the most important substances in the world of oleochemicals as it is an ingredient that is applied to many products. It is an extremely versatile molecule that is used in virtually all fields of industry.

  • Food(food grade): additive E-422 present in many preparations.
  • Animal Food (feed grade): moisturizer, additive, etc.
  • Pharmacy/Medicine: different qualities depending on the established regulations (USP, EUP, GBP…), it can be used in multiple preparations such as suppositories, additives, lubricants, coadjuvants… In this sector, it is frequently used.
  • Other sectors such as: cosmetics, detergents, softeners, tobacco, explosives, esters, polymers, paints

Glycerol or glycerinAs can be seen, this element is widely used in different sectors. And it is that its use is very extended in diverse types of businesses.

Glycerin is a very important medium in the oleochemical industry. Its plasticity and excellent properties allow a wide range of uses in different markets. The safety of plant glycerin, the efficiency and performance of oleochemicals are sometimes superior to those of chemicals.

Oleochemicals are an increasingly attractive alternative for different industries, since they are a fairly ecological and profitable medium that also meets the highest expectations. For this reason, we make a wide range of products available to different markets in order to manufacture all types of industrial goods and articles.

Glycerin is, without a doubt, one of the most relevant and powerful substances in the oleochemical market.
