Which chemical is known to leave a residual film after use?

Phenolics are known for leaving a residual film after use, which can be a concern in various applications, including healthcare settings. This characteristic is due to the way phenolic compounds adhere to surfaces, creating a protective film that can persist. While this film may offer antimicrobial properties, it can also hinder the thorough cleaning of surfaces if not properly managed after application.

On the other hand, glutaraldehyde, chlorine, and alcohol typically do not leave a significant residual film after their use. Glutaraldehyde is primarily used as a high-level disinfectant and would evaporate or break down without leaving a film. Chlorine is often used in various disinfectant applications and reacts with surfaces, also largely avoiding film formation. Alcohol, used for its quick evaporation properties, is effective in disinfection without leaving a residue that could affect subsequent uses.

In summary, the residual film characteristic of phenolics is significant for sterile processing technicians to consider, as it can impact both cleaning protocols and the overall effectiveness of subsequent sterilization processes.
