What is the correct percentage of sodium hypochlorite to water when mixing an intermediate level solution of sodium hypochlorite for surface disinfection?

The correct percentage of sodium hypochlorite for an intermediate level solution used in surface disinfection is typically around 10%. This concentration is effective in eliminating a range of pathogens, including bacteria, viruses, and fungi, making it suitable for disinfection in healthcare and dental settings.

When preparing this solution, it’s important to ensure that the concentration is high enough to achieve the desired antimicrobial effect but not so concentrated that it poses a risk to surfaces or safety during handling. A 10% solution is commonly recommended as it strikes this balance effectively, ensuring optimal microbial action while being manageable for users in clinical environments.

Using percentages outside of this recommended concentration may not provide adequate disinfection capabilities or might lead to damage to surfaces or increased hazards. Therefore, for the purpose of creating an effective disinfectant that meets infection control standards, the 10% concentration is the appropriate choice.
