Polymer degradation is a significant process that results in the deterioration of polymer properties and performance over time. The causes of degradation are multifaceted, primarily including exposure to environmental factors such as ultraviolet (UV) radiation from sunlight, oxygen, ozone, and other atmospheric gases. Additionally, thermal degradation due to high temperatures can break down polymers through bond scission. Chemical reactions, involving hydrolysis or oxidation, can also lead to the breakdown of polymers, particularly in the presence of acids, bases, or other reactive substances. Moreover, mechanical stress and biological factors, like the action of microbes, contribute to the degradation process. The detrimental impact of these factors can be mitigated through the use of stabilizers, antioxidants, and UV absorbers, which enhance the durability and lifespan of polymer-based products.
Hydroxyethyl cellulose (HEC) is a non-ionic, water-soluble polymer derived from cellulose, the most abundant organic polymer on Earth. Unlike some other cellulose derivatives, HEC does not naturally carry a net positive or negative charge, hence its classification as non-ionic. This property makes HEC particularly useful in a variety of applications, including as a thickener, emulsifier, and stabilizer in products ranging from cosmetics and pharmaceuticals to construction materials. Its lack of ionic charge means it is less likely to react adversely with other components in a solution, making it versatile and compatible with a wide range of additives. In contrast, anionic or cationic cellulose ethers have been chemically modified to carry a charge and are used in applications where specific interactions with ions are necessary.
