The most crucial factor for Ethylene Oxide (EO) penetration into the microbial cell is humidity. Ethylene Oxide is a gas used for sterilization, particularly for heat-sensitive items. Its effectiveness is significantly enhanced in the presence of moisture.

Humidity facilitates the diffusion of EO into microbial cells, as the moisture in the environment helps to enhance the permeability of the cell membrane. In dry conditions, EO molecules have a reduced ability to penetrate the cell wall, leading to less effective sterilization. Therefore, maintaining adequate humidity levels is pivotal in ensuring that EO can fully penetrate and interact with microbial cells, thereby achieving the desired sterilizing effect.

While time, temperature, and aeration are important factors in the overall sterilization process, they are not as directly influential on the penetration of Ethylene Oxide into the cells as humidity. Time affects the duration of exposure necessary for sterilization, temperature influences the reactivity of Ethylene Oxide, and aeration is critical post-sterilization for removing residual gas. However, without sufficient humidity, the primary action of EO in penetrating and effectively sterilizing the target cells is compromised.
