Investigating the Temperature at Which Soap Powder Will Perform Best At

Introduction

I am going to conduct an experiment in the controlled environment of a

laboratory. The experiment will consist of placing a stained piece of

fabric into water with a fixed concentration of a biological washing

powder (Wizzo) in it. I will try this experiment several times trying

different temperatured water and leaving the it for a fixed period of

time to find the best possible temperature that the Wizzo works at.

Plan: Enzymes

Biological washing powder has bin around for many years to clean

clothes more efficiently. We know washing powder helps in the cleaning

process because it contains enzymes. Previous experiments have found

that the enzymes break down larger dirt molecules into smaller dirt

molecules. Therefore speeding up the process of cleaning clothes

(catalyse) as the water can wash them away quicker.

Another example of enzymes is the digestive system in the human body.

Enzymes called protease are produced by the stomach, the pancreas and

the small intestine. These enzymes catalyse the break down of fatty

acids into amino acids. These enzymes work best at 37 degrees celsius

whcih is body temperature.

Formalahdehyde is the enzyme which is commonly found in biological

washing powder. The enzymes break down the dirt molecules in clothes

into smaller dirt molecules thus making it easier for the water to

clean away. I will determine at what temperature the enzymes in the

Wizzo best perform at, which is the point of my experiment.

...s of stained fabrics I could

use therefore limiting the amount of times I could repeat each

temperature. Also some of the fabrics were not made out of the same

material and therefore may influence the time in which it takes to

clean it making the test void or unreliable.The size of the stains

also varied also making the test unreliabledue to it will also take an

untrue time to remove the stain in the sane concentration of solution.

To obtain more reliable results I would repeat the experiment more

times (about ten times for each temperature) to get a broader range of

results for the average.

To extend the experiment further I would conduct the same experiment

using lower temperatures to be able to copmile the results from this

experiment to get a broader range as it seems the Wizzo will be more

effective again.
