Stearic Acid Disadvantages
The disadvantages of stearic acid
Although stearic acid is common in various chemical applications, it also has many drawbacks.
First, stearic acid has poor stability under certain specific chemical reaction environments. In case of high temperature and aerobic conditions, it is easy to cause oxidation reactions, resulting in changes in its chemical structure, which in turn damages the quality of products made from this raw material. For example, in high-temperature processed plastic products, the oxidation of stearic acid can cause yellowing of the product color, reduce mechanical properties, and shorten the service life of the product.
Second, the solubility of stearic acid is limited. In many organic solvents and water systems, its solubility is difficult to meet the needs of some fine chemical production. In the preparation of water-based coatings, stearic acid is difficult to disperse uniformly, resulting in surface irregularity and uneven gloss after coating formation, which seriously affects the decoration and protective properties of coatings.
Furthermore, stearic acid has poor biodegradability. It takes a long time to decompose in the natural environment. If it is discharged in large quantities, it is easy to cause pollution to the ecological environment such as soil and water. And in organisms, stearic acid is difficult to be effectively metabolized, or it will accumulate in organisms and be transmitted through the food chain, causing potential harm to organisms in the ecosystem.
And because of its physical properties, stearic acid is also inconvenient during storage and transportation. It is mostly solid at room temperature and requires specific conditions to maintain its stable shape, otherwise it is prone to agglomeration due to changes in temperature and humidity, which will affect subsequent access and processing.
