Propylene glycol; application, properties and features
Propylene glycol is a chemical of the family of alcohol. This chemical is one of the most widely used industrial materials that covers a wide range of large and small industries.
Propylene glycol is represented by Latin Propylene Glycol and consists of carbon, hydrogen and oxygen atoms. The chemical formula of propylene glycol is represented by the symbol C3H8O2. This chemical is colorless, odorless and in the form of a liquid that has a sweet taste. Propylene glycol toxicity is minor, but when working with it, you should observe individual safety and hygiene considerations.

Safety Notes and Cautions for Working with Propylene Glycol:
Considering that the propylene glycol chemical substance is an integral part of the products of cosmetic, health and medicinal products, it is necessary and necessary to pay attention to the essential points and the risk factors and the risk factors associated with this widely used chemical. In the following, we will discuss some of the most important warning signs and safety tips for propylene glycol. Stay with us.
Generally speaking, propylene glycol is known as an additive and concentrator for a variety of cosmetic and pharmaceutical products. Obviously working with this chemical, especially in high concentrations, will create a series of allergic symptoms that threaten the health of an individual.
Frequent skin contact with propylene glycol causes irritation and itchy skin. If skin contact with this material, skin should be washed quickly with water. If a person accidentally drops propylene glycol through the mouth, it may cause liver and kidney function impairment.
Propylene glycol is a no odorless liquid, but if vapors are inhaled by the nose, it can stimulate the respiratory system and the lungs. The occurrence of acute pulmonary problems and, in some cases, asthma is a consequence of inhalation of propylene glycol vapors.
It is recommended that all personal and industrial safety related chemicals be used in factories and industries where individuals and employees are involved in different areas of laboratory, production, quality control and transportation of propylene glycol barrels. . The requirements and instructions that are required when working with propylene glycol should be given to these people. The health of the employees of the industry is more important than anything else and will increase the efficiency and efficiency of that industry.
