What is the difference between
COMMERCIAL
SOAPS
(Hot Processed)
and
HANDMADE SOAPS
(Cold Processed)?
Commercial soap (i.e. Irish Spring, Dove,
Palmolive, Safe Guard, Body Shop soap)
is manufactured by using a
Hot Process Method.
During the
hot process, oils and alkali are boiled
together for a period of time to create saponification.
During the boiling, the
SOAP BY-PRODUCT and GLYCERIN
separate.
Usually the GLYCERIN is
SEPARATED and
SOLD.
The remaining
SOAP MIXTURE is then
formed into bars.
Since the soap
mixture is boiled for such a long time,
the oils in the hot soap process
tend to go
RANCID. So to counter the rancidity,
CHEMICALS are
ADDED to keep
it FRESHER for
LONGER SHELF LIFE.
The
Cold
Process
Method
of production where oils are
mixed just to the melting temperature
and mixed with an alkali to create
saponification. It is then poured into
molds, cooled down, and then cut and
cured for approximately one week.
Because cold process soaps
retain their
naturally-occuring glycerin, and natural
herbal extract oils are not boiled, they
do not need
TO BE added WITH chemical preservatives.
