Make Modern Soap With Herbs, Beeswax
And Vegetable Oils
By Elaine White
These instructions are very condensed
and cannot possibly contain the details included in my 'Soap
Recipes' book. Nonetheless, I believe you will have a good overview
after you read these instructions.
The equipment list:
one 4-to-6 cup mixing container
made of lye-resistant material (I use a stainless steel mixing
bowl)
one heatproof container that holds at least 2 cups (I use a Pyrex
measuring cup)
stainess steel, plastic, wooden spoon or a rubber spatula
two thermometers made of glass or stainless steel (candy and
meat thermometers work well)
|
eye protection (wear sunglasses
if you have to!)
rubber gloves (optional)
accurate scale to weight the fats and lye
soap molds (any flexible plastic container works well)
a clock with a second hand or other type timer
wire whisk (optional)
pot holders or oven mitts
measuring spoons
The Ten-step Procedure
1) Heat the fat. Put the fats in a lye-resistant
container and place a glass or stainless steel thermometer into
the fats. Be sure the thermometer doesn't touch the bottom of
the container and give a false reading. Heat the fats and optional
ingredients to the temperature specified in the recipe.
2) Put on eye protection and rubber gloves. |

3) Use a heat-proof container to measure the amount
of cold water (70 to 75 degrees F) specified in the recipe. Cold
water is important. If you add lye to hot or boiling water, the
water could "boil-up" out of the container.
If you add lye to *really* cold
water, the lye/water might not reach the high temperatures required
to make some recipes.
Stir the water and slowly add
the lye. The water will get hot and turn cloudy. Continue to
stir until the lye dissolves. Don't breathe or intentionally
smell the fumes coming from the cup because they are quite "chokey."
If you wait too long to stir the water, the lye could harden
in the bottom of the container. This is not a problem. You can
still sitr it, but it will be more difficult. Add a glass or
stainless steel thermometer to the lye/water and wait until it
reaches the temperature specified in the recipe.
4) When both the fat and the lye/water reach the
temperature specified in the recipe, add the lye/water to the
fat. It's sometimes a balancing act to get the fat mixture and
the lye/water mxiture to specific temperatures at the same time.
Never place lye/water in a microwave (the cup could break).
It takes lye/water longer to
cool than it takes fat to heat. Most soapmakers wait for the
lye/water to cool to about five degrees above the desired temperature,
then heat the fat. When both the lye/water and the fat are within
five degrees of the temperatures specified in the recipe. Use
a pot holder and move the bowl to a sink (to contain splatters).
Slowly pour the lye/water into the fats while stirring.
Temperatures for small one-pound
batches of soap poured into individual molds aren't critical.
As long as the lye/water and fats are between 120 and 140 degrees
F you will have good success. Larger batches or batches poured
into a single mold, require lower temperatures.
5) Stir the soap until it "traces."
When lye, water and fat first combine, the mixture is thin and
watery. Gradually, as the lye and fat react chemically to form
soap, the mixture thickens and turns opaque.
"Tracing" is a term
to describe the consistency (thickness) of soap when it's ready
to pour into molds.
To test for tracing:
a. Drip some soap onto the surface
of the soap in the stirring bowl. It should leave a "trace"
or small mound.
b. Draw a line in the soap with
a spoon or rubber spatula. If a "trace" of the line
remains for a few seconds, the soap has traced.
Tracing is easy to recognize,
yet it causes new soapmakers a lot of worry. Relax and know that
the soap will trace eventually. Just stir the soap constantly
for the first 15 minutes or so, then stir the soap every fifteen
minutes until it thickens and traces, no matter how long it takes.
6) After the soap traces, add up to one tablespoon
essential oil (if desired) and stir a few minutes longer to incorporate
the oil. About the only soap that remains totally scent-free
is the Pure Soap Recipe that follows. Other fats result in soap
that has a "fatty lye" smell. Essentials oils are necessary
for a pleasant-smelling product.
7) Pour the soap into molds and wait for it to harden.
The recipes states this length of time as 'time in mold.'
8) Unmold the soap.
Soap is still harsh when it's time to remove it from the molds.
Put on rubber gloves and press the back of each mold compartment
to release the soap. It's a lot like removing ice cubes from
a tray. Sometimes the soap doesn't release easily from the mold.
To overcome this problem, leave the soap in a freezer for a few
hours. Freezing soap causes it to contract slightly, become hard
and release from the plastic mold.
9) Wait the time specified in a recipe for the soap
to"age" (usually 3 weeks). During the aging time the
pH of the soap decreased (the soap becomes mild) and the bars
harden. It's a good idea to write the following information on
a piece of paper and place it with the soap: the date you made
the soap, the date the aging time is over, and recipe.
10) Step 10 is *enjoy your
soap!*
As soap ages, a fine, white powder
may appear on the surface. This is soda ash (sodium carbonate)
formed by a reaction of lye with carbon dioxide in air. This
white powder is mostly on the surface exposed to air while the
soap was in the molds. Soap that contains wax develops little
or no soda ash.
There are three ways to deal
with soda ash:
Try to prevent it.
Immediately after pouring soap into molds, cover the soap with
plastic wrap or waxed paper. Press the wrap or paper onto the
surface of the soap to prevent air contact.
Cut it away.
Overfill the molds slightly. Later, when the soap hardens, take
a knife and cut the soap level with the mold. This also cuts
away the soda ash.
Wash it away.
Wait until the soap ages and hardens. Wash the powder away by
rubbing the soap with your hands under running water or by rubbing
the soap over a wet dishcloth. Set the soap aside to dry then
enjoy your soap! |
