Buy Glycerine USP


Glycerine USP is a viscous, colorless, and sweet-tasting substance widely used in pharmaceutical and cosmetic industries. It is usually added in soaps, lotions, sunscreens, shaving creams, syrups, sweeteners, and toothpastes. Glycerine is soluble in water, has a high boiling point, and freezes to a paste.

Propane-1,2,3-triol is the compound’s official IUPAC name. Glycerol, glycerin, and glycol alcohol are some of its popular synonyms. Glycerine has HOCH2-CHOHCH2OH for its chemical structure, which consists of three carbon atoms, two of which are attached to two hydrogen atoms and a hydroxyl group. Simultaneously, the central carbon atom is attached to a hydrocarbon and a hydroxyl group. Because of this hydroxyl bond, glycerin is classified as an alcohol (trihydric group).

Karl Wilhelm Scheele discovered glycerin in 1779 after he isolated the compound from a mixture of olive oil and lead oxide (PbO). It was later discovered by Alfred Nobel to be a component of explosives, making it an important commodity during the two world wars. Today, glycerine is produced through biodiesel production or soap making process.

Glycerine has a vapor pressure of 0.0002 mmHg in 25°C and a vapor density of 3.17 (Air=1). Its molecular weight is 92.09, with a melting point of 19°C and a boiling point of 290°C. Saturation value of glycerin is set at 0.0003% at 50°C, while its density is set at 1.261 g/cm3 at 20°C. 577°C is its critical temperature and 74.02 is its critical pressure. Aside from water, glycerine is soluble in acetone and alcohol while insoluble in benzene and ether.

Glycerine should be stored in a tightly closed container, away from other incompatible compounds. Wash hands well before and after using the substance and wear protective clothing (laboratory gown, gloves, chemical safety glasses, or protective eyeglasses). Use product in well-ventilated areas. Clean up spills immediately using inert materials before disposing in chemical waste bins. Glycerine is combustible so remove all sources of ignition. No other special precautions are required.

In case of glycerine ingestion, DO NOT induce vomiting. If victim is unconscious, never give anything by the mouth; if conscious and alert, rinse mouth and let victim drink 2-4 cups of milk or water. In case of inhalation, remove the person from the area of exposure immediately. Supply oxygen if the person experiences breathing difficulties. Wash skin with plenty of water and soap for about 15-20 minutes if skin is exposed by the chemical. Remove contaminated clothing and wash well before reuse. Wash eyes with clean running water for at least 15-20 minutes, or until irritation subsides. Seek immediate medical help.
