 This is a common
formula:
1. Olive or
cottonseed oil.................................. 60 parts
Caustic potash, U.S.P........................................ 15 parts
Alcohol and water,
sufficient of each.
Dissolve the potash
in 1 ounce of water, heat the oil on a water bath, add the solution of
potash
previously warmed, and stir briskly. Continue the heat until saponfication is complete. If oil globules
separate out and refuse to saponify, the potash is not of proper strength, and more must be added-1 or
2 parts dissolved
in water. If desired transparent add a little alcohol, and
continue the heat without stirring until a drop placed in cold water
first
solidifies and then dissolves.
Commercial potash
may be used, but the strength must he ascertained and adjusted by
experiment. The soap
thus made will be like jelly; it is dissolved in
alcohol, 4 to 6 ounces of soap to 2 of alcohol, and after standing a day
or
two is filtered and perfumed as desired. A rancid oil would be easier to saponify, but the soap would likely be
rancid or not as good.
2. Ammonium
sulphoichthyolate, 10 parts; distilled water, 15 parts; hebras soap spirit
(a solution of potash soap,
120 parts, in 90 percent spirit, 60 parts; and
spirit of lavender, 5 parts), 75 parts.
