Note - Before you begin you will need to decide
on a soap recipe.(Check our soapmaking link below for free recipes.) I
would suggest using one that includes Palm or Coconut oil.
These two oils make for a hard bar of soap and have a fairly quick trace
time. Also, it is recommended that you run whatever recipe you choose
through a lye calculator like Soap-Calc or one of the free online ones.
This way you can adjust the lye content to leave the desired amount of
excess fat in your soap. A bar with a lot of excess fat (over 5%)
will moisturize your skin better than one with less than 5% however the
one with less than 5% will leave you feeling cleaner. A lot of this
depends on your skin type.
Making Soap in a Blender
Although using a blender does
not allow for big batches of soap, it has four major advantages:
1) Blending your soap mix makes
for a much shorter time to the thin trace stage. Instead of 15 - 40 minutes,
it might require only minutes or even seconds.
2) Since liquid fat and oils
can be used at room temperature, no thermometers are required. For solid
fats simply heat them until they are melted.
3) The blender effectively whips
the lye water into the fats producing a much smoother mixture so the chances
of your mix separating are greatly reduced.
4. Your soap bars will be creamier
in consistancy and should float due to the air that is whipped into the
(Use small one-pound batches
Step One - Dissolve the lye
in cold water and wait until it cools and the mixture turns clear. Make sure you are wearing goggles and gloves when handling lye. Never pour water into lye. Only pour lye INTO water.
Step Two - Carefully pour the oil
and then the lye/water solution into the blender. Be careful not
to splash or spill the lye on yourself or others. Make sure you are wearing goggles and gloves.
Step Three - Lock the blender in
position, secure the cover, place a towel over the top of the blender for
safety, and process at the lowest possible speed. Make sure you are
wearing your goggles when you process the soap mixture and make sure the
towel is in place to avoid any accidental splashing of the lye/oil mixture.
Stop the blender and check the soap
often to watch for what is called a thin-trace stage. This is when
the soap mixture just begins to thicken. Each time you stop the blender,
wait a few seconds before removing the cover. Sometimes the soap "burps"
when it stops as trapped air comes to the top. At the thin trace stage,
stop the blender and stir the soap to check for tracing and to allow bubbles
to escape. Step Four - At this point you
can add any essential oils,colorants or fragrances as well as any other
ingredients such as oatmeal or herbs. Blend these in for a few seconds
and then stop the blender.
Step Five - Pour the soap into individual
molds. Cover it with a blanket for insulation. Let the soap set for a day
or two and then after popping it out of the molds cut it and let it age
for at least three weeks.
