Polyethylene Glycol (PEG): Concepts, Applications, and Side Effects
Polyethylene Glycol (PEG) is a polymer compound produced from ethylene glycol through the combination of ethylene oxide molecules with it. It is one of the most important derivatives of petroleum, with a wide range of applications in various industries, from industrial to medical and even cosmetic and personal care. Due to its non-toxic and non-hazardous properties, it is used as a safe substance in various consumables. This article aims to explore the concepts, applications, and side effects of polyethylene glycol and provide comprehensive and useful information in this field.
Part 1: Introduction to Polyethylene Glycol
1. History and discovery of this compound:
Polyethylene Glycol was first discovered by Charles Edward Ballard in 1844. He prepared this compound from ethylene glycol as the main ingredient in anti-freeze. Since then, polyethylene glycol has been recognized as an essential and versatile substance in various industries.
2. Structure and properties of polyethylene glycol:
Polyethylene Glycol is produced as a polymer molecule with a repetitive number of ethylene oxide groups. It possesses unique physical and chemical properties, making it a versatile and efficient material in various applications. Its properties include melting point, density, color, and odor, all of which are non-hazardous.
3. Behavior in water and solubility:
Polyethylene Glycol is known as a hydrophilic and soluble polymer. This characteristic makes it an effective lubricant and moisture-absorbent in cosmetic and personal care products. Additionally, it is used as a solvent in the formulation of some medicines and food products.
Part 2: Applications of Polyethylene Glycol in Industries
1. Use in formulating oils and organic insecticides:
Polyethylene Glycol is used as an effective lubricant in the formulation of oils. This feature makes it a useful solvent in organic insecticides as well. Furthermore, its high resistance to heat and moisture makes it a suitable choice for formulating products in this category.
