Biological vs. Non-Biological: Which is Better?
Biological Washing Powder
Biological washing powder contains enzymes which are harvested micro-organisms like bacteria adapted to live in hot springs. They clean in the same way as non-biological detergent but with additional effects from the enzymes. For some people, biological detergents irritate their skin and cause them to have skin conditions such as eczema.
Non - Biological Washing Powder
Our Investigation
We wanted to find out whether biological washing powder or non-biological washing powder worked better when we washed a stained piece of cloth and which temperature made the washing powder most effective.
When washed at 60°...
When washed at 90°...
The Method
We started with 6 cloths, 3 that were stained with tea and 3 cloths that were stained with ketchup.
Each piece of cloth was then placed in a separate beaker with 1 heaped spatula of non-biological washing powder.
We then added 75ml of water to each beaker and put the beakers into water baths. Each of the water baths (heated to 40°, 60° and 90°) had one beaker containing a ketchup stained cloth and one beaker containing a tea stained cloth in it.
We timed how long each cloth took to become clean again and recorded out results in a table.
We then hung the cloths to dry and repeated the whole process with new pieces of stained cloth and biological washing powder instead of non-biological powder.
For the experiment, you will need...
6 cloths stained with tomato ketchup
6 cloths stained with tea
6 beakers
a spatula
non-biological washing powder
