The Hand Sanitizer Effectiveness ranking system is based on a combination of objective scientific and clinical data. For the purpose of this ranking, the body and face area were considered. This system was developed to help doctors in determining the sanitizer that should be used on the infected areas.

The hand sanitizer Effectiveness scores are calculated by taking into consideration the number of germ-free sanitizers used. The formulas are based on factors such as the surface area. If the surface area is large, then it is more likely that there will be more than one germ. Thus, one should use a sanitizer on the entire surface area of the hands and the feet.

There are other factors that are considered for calculating the Hand Sanitizer Effectiveness. These include:

Efficacy scores for a particular sanitizer are derived from the number of germs eliminated by the use of the product. Generally, products with low efficacy are not recommended. The formulas for a sanitizer’s Efficacy score use the number of surfaces being used. In general, products with a low Efficacy score are not recommended. Some formulas for the Hand Sanitizer Effectiveness score using only the number of surfaces in contact with the body to calculate efficacy. However, most formulas rely on the surface area. Products with a low surface area are not recommended.

**Other factors considered in calculating the Hand Sanitizer Effectiveness are:**

The surface area for the products is very important for determining how effective the product is. In fact, the Surface Area percentage is the sole factor for calculating the efficacy. This factor is based on the number of microorganisms that could be present on the surface of the sanitizer. Based on the other factors, the formula is adapted to calculate the Efficacy score. The formulas are based on several factors. First, the surface area is used to estimate the probability of multiple organisms. Secondly, the surface area is used to determine the number of potential organisms per surface. Finally, the formula utilizes the ratio of the surface area to the total surface area to compute the score.

The factors used in the formulas for the Hand Sanitizer Effectiveness are determined based on scientific studies and laboratory tests. In addition, there are other factors that are taken into consideration. These include:

There are some formulas that are based on what a user wants. For example, the user might want a product that is safe to use on his or her hands, on a child’s hands, or even on an adult’s hands. The factors that are applied in the formulas are determined based on factors such as the patient’s preference. There are also factors that are based on the patient’s safety.

The hand sanitizer effectiveness is calculated by taking into consideration the type of surface being used, the amount of surface area and the efficacy of the sanitizer. Additionally, the factors are based on research findings. For example, these findings take into account the percentage of contamination, the number of microorganisms that are present, the potential for cross-contamination, and the efficacy of the sanitizer.
