The glycerin molecule consists of carbon atoms, oxygen, and hydrogen. Glycerin can be called alcohol as a factor in which the position of hydroxy groups in it will create the physical and chemical properties of the molecule. The glycerine structure is shown in the form.
Glycerin is mainly soluble in water, but dissolves in very small amounts in other alcohols. The properties of this substance are based on the production of ester and fat. The general characteristics of glycerin and the physical and chemical properties of this substance are fully described in the table below.

As noted in the previous sections, glycerin is commercially available and commercially available in two edible and industrial grades. The food industry, pharmaceuticals and other products that use glycerin as one of their ingredients should be well aware of the properties and characteristics of this substance and, most importantly, the safety tips of working with glycerin or its MSDS.
Glycerin has a fairly sweet taste, but this does not mean that it can be ingested or if it is swallowed by an individual, no symptoms result. If glycerin is accidentally contacted by skin or eyes, it will cause severe irritation and penetration into the pores of the skin. In case of inhalation of vapors, the respiratory system is also stimulated and has acute effects.
There is still no evidence of the effects of contact with glycerin on the liver or human genetics, but long-term exposure to this chemical can have toxic effects for the kidneys and is harmful to the organs of the body.
In case of glycerin contact with eyes and skin, quickly wash the contact area with water and consult a physician if intensive inflammation occurs. In many cases, washing with cold water is very effective. In case of glycerin vapors, it is necessary to use pure oxygen to reduce its harmful effects, and the person should refer the doctor quickly.
