Conversely, in highly acidic environments, it may undergo unwanted side reactions, further compromising its stability and functionality.

Temperature fluctuations also pose a significant threat to carbolic acid stability. Elevated temperatures can accelerate degradation processes, while freezing can cause phase separation in aqueous solutions, potentially leading to concentration inconsistencies and reduced efficacy upon thawing.

The presence of metal ions in aqueous solutions can catalyze the oxidation of carbolic acid, further exacerbating its instability. This is particularly problematic in industrial settings where metal contamination is common, necessitating additional purification steps or the use of chelating agents to mitigate this effect.

Furthermore, the volatility of carbolic acid in aqueous solutions presents challenges in maintaining consistent concentrations over time. Evaporation can lead to gradual increases in concentration, potentially altering the solution's properties and effectiveness.

These limitations collectively restrict the use of carbolic acid in various applications, particularly those requiring long-term stability or exposure to challenging environmental conditions. They also necessitate complex and often costly stabilization techniques, which can be impractical for large-scale industrial use.

The field of enhancing carbolic acid stability in aqueous solutions through nanotechnology is in its early developmental stage, with significant potential for growth.
