Most of the enzymes for “biological” washing
powders come from bacteria adapted to live in hot
springs .
Washing powder enzymes must also be able to
function at alkaline pH, due to the presence of
phosphate ions in most detergents.

What is the difference
between biological
washing powder and
regular washing
powder?
BIOLOGICAL DETERGENTS

The first patent for a
protein-digesting
enzyme was issued
back in 1913, and this
enzyme was extracted
from animal
pancreases.
BIOLOGICAL DETERGENTS

In the 1960s, a much
more useful enzyme
was obtained from a
bacterium
called Bacillus
subtilis.
BIOLOGICAL DETERGENTS

It is known that many
stains are difficult to
remove with ordinary
detergents such as
blood, gravy…
BIOLOGICAL DETERGENTS

Proteases break
down proteins, so are
good for blood, egg,
gravy, and other
protein
stains. Amylases bre
ak down starches,
and lipases break
down fats and grease.
BIOLOGICAL DETERGENTS
 The
most
important enzymes
used in biological
washing powders
is protease.
