Utilization of Calamansi (Citrofortunella Microcarpa) into Homemade Foot Powder

2. Chapter 1
Background of the Study Body odor (esp., foot odor), or the unpleasant smell of bacteria growing on your body . The main cause is foot sweat . Sweat itself is odorless , but it creates a beneficial environment for certain bacteria to grow and produce bad - smelling substances . These bacteria are naturally present on our skin. Therefore , more smell is created with factors causing more sweating , such as wearing shoes and socks that lacks air ventilation for many hours . Hair on the feet , especially on the toes , may contribute to the odor's intensity by adding increased surface area in which the bacteria can thrive. Foot powder is a type of powder which absorbs sweat that causes odor to the foot. Calamansi is a tropical fruit usually found at the Philippines. This is commonly made into juice drinks, additive to common native sauces (e.g., toyo) and even as a body odor repellant.. The small circular fruit prevents body odor especially the armpit odor.

3. Statement Of The Problem
Main Problem: Is the product reliable?
Sub Problems:
Can this product absorb enough sweat?
Is this product irritating to skin?
Can this product kill bacteria?
Is the product cheaper?

4. Formulation Of Hypothesis
The said product can not absorb sweat , kill bacteria , nor remove bad odor from foot . The product is less reliable than the commercial foot powder

5. Scopes and Limitations
15 athletes will be randomly selected for them to use the said product. Another 15 athletes will be randomly selected for them to use a commercial footpowder. We will compare the result according to the data gathered. The participants will rank the product they used using the scale below:
5 – Effective
4- Less Effective
3- Could Not Decide
2- Removes Less Odor
1- Could Not Remove Odor All

6. Definition Of Terms
