are used to enhance efficiency.
THE ADDITIVES IN DETERGENT AND THEIR RESPECTIVE FUNCTIONS
Additive
|
Function
|
Biological
enzyme
(e.g.
amylase, protease, cellulase, lipase) |
To
break down and remove stains such as proteins, fats,
carbohydrates, blood and oils. |
Builder
(e.g.
sodium phosphate, sodium tripolyphosphate) |
To
enhance the surfactant efficiency by lowering the water hardness
because magnesium and calcium ions will combine with phosphate
ions to form metal phosphate precipitates. |
Filler
(Drying agent)
(e.g.
sodium sulphate, sodium silicate) |
To
make the solid detergent dry and enable the liquid detergent to be
poured easily.
|
Fragrance |
To
give detergent and fabric smells better. |
Optical
brightener
(e.g.
fluorescent dye) |
To
convert some ultraviolet radiation to blue light and cause the
fabrics look brighter and whiter rather than yellow.
|
Stabilising
agent
(e.g.
silicones, diethanolamide) |
To
lower the production of foam especially during the usage in a
washing machine. |
Suspension
agent
(e.g.
sodium carboxymethylcellulose)
|
To
increase the negative charge on cellulosic fabrics such as cotton
and rayon. This will prevent the dirt particles removed from
redepositing onto the cleaned fabric. |
Whitening
agent
(e.g.
sodium hypochlorite, sodium
percarbonate, sodium perborate) |
To
bleach the white fabrics but does not bleach the dye on the
coloured fabric. |
