Catalysts - Enzymes - Biological Detergents.
Which Enzymes are used in Biological Detergents?
detergents and washing
powders use lipases
and proteases to break down fat and protein
molecules from food stains that have remained on clothing.
The fatty acids, glycerol and amino acids which are produced
are removed in the water during the washing process.
What are the Advantages
of using Enzymes in Biological Detergents?
The use of enzymes in
detergents has the advantage
that effective washing can be carried out in warm water.
Warm water is preferable to hot water because
1) it is more energy efficient
(you don't have to heat the water so much).
2) the dye in coloured clothing is
less likely to wash out of the fabric.
3) clothes are more
likely to stay the
(hot water causes some fabric to shrink).
