A quantity of caustic soda is precisely calculated against the
saponification values of the
fats being used and measured by weight. It is then
carefully mixed with the correct amount of
triple-purified springwater. As a result the water heats to
nearly boiling. After the solution
is cooled, it is added to the blend of oils and fats.
"Grandma's soap" had it's rough
reputation because there was no accurate way to calculate
or measure the correct
amount. Because the caustic solution is totally taken up in the
(soapmaking) process, our soaps are gentle and mild.
