The enzymes of the biological washing powder broke the egg yolk into smaller molecules that lift off the spoon and dissolve in the water. This did not happen in the non-biological powder or in the control. Conclusion. Biological washing powders are better than non-biological washing powder at removing organic stains from clothing.
2022-6-1 · One of the primary reasons that enzymes are used in biological washing powders is that the additional stain-removing help from the enzymes means that dirt can be removed without the need for hot water. Biological detergents are effective at much lower temperatures, helping families all across the UK to save money on their household bills, and ...
