What Is A Polyethylene Glycol Ester

Polyethylene glycol ester refers to the saturated fatty acid prepared by reacting a fatty acid with polyethylene glycol. The glycol comprises the lipophilic part of fatty acid and the hydrophilic portion of the surfactant. It can also be used to produce a range of HLB values by simply varying the molecular weight of the fatty acid and PEG.

The compound can be put into many applications. It can be used as a medicine, put to commercial use, and industrial manufacturing. The compounds’ molecular weight determines the use it can be put to. Here are some of the most common uses.

1. Medical use

Polyethylene glycol ester is commonly used as a laxative. When added to electrolytes, it can be used to prepare the bowel before colonoscopy and surgery. Also, PEG is an important recipient in the manufacturing of pharmaceutical products. It can be attached to the protein medication to help remove protein from the blood. It can also be fused with axons to be used to study the spinal cord injury and peripheral nerve.

2. Chemical uses

Polyethylene glycol ester could be used as a passive microscope glass slide. It has low toxicity and thus can be deployed in many products, including lubricants and coating compounds. One important thing to remember about polyethylene glycol esters is that it is a soluble polymer that could be used in creating high osmotic pressure. This makes it a useful molecule in biomembrane and biochemistry experiments.

Also, polyethylene glycol esters can serve as a stationary phase in electronic testers and gas chromatography.  PEG can be used in preserving objects recovered from underwater. When applied to wooden objects, it replaces water and prevents shrinking and warping. It makes the wood stable and allows it to be put to various applications. 

The compound can also be applied to unearthed artifacts to aid in preserving colors. This is vital in helping conserve unearthed artifacts, and it helps to preserve painted colors.

Elsewhere, the U.S. army has used PEG as fuel in some of its missiles. Thus, it is an essential compound in warfare.

3. Biological uses

PEG is an outstanding crowding agent since it can easily mimic cellular conditions. Besides, it is an essential compound in protein crystallization and DNA isolation.  In some other applications, the compound could be used to fuse cells of a different type when creating hybridomas. Thus the method could be used to produce antibodies

In some other cases, PEG can be used to concentrate viruses in microbiology. Also, it can be used to coat the virus and stop them from being active. Besides, Polyethylene Glycol Ester plays an important role in detecting antibodies and antigens. This is vital in blood banking. In the laboratory setting, PEG can be used to deactivate phenol after suffering from a phenol skin burn.

4. Commercial uses

The compound is used to make skin creams and toothpaste. It binds water and could help to maintain uniformity in the distribution of toothpaste particles.

Polyethylene Glycol Ester is an important compound that finds a lot of applications in the industrial and commercial environment. It is also an essential compound in chemical and medical fields.  Thus it is one of the inventions that have made the world a better place.
