How is soap made? It all starts at home.
First you must find fatty acids, these can be found in animal fats
(which i never use in my products), or oils or butters extracted from
plants. When a fatty acid is mixed with a strong alkali, magic happens.
Most people prefer to use sodium hydroxide or potassium hydroxide (for
liquid soaps), but the ancient way would be to use water strained
though white ash from wood, preferably apple. I do not use ash, for it
is dirty and its strength changes with every use. You will also need to
gather any botanicals, scents, or colors you wish to add to your soap.
Now that we have everything, mix your alkali with a liquid that’s water
soluble, like water, milk, tea, etc. Remember: always mix you alkali
with your water, and not your water with you alkali, or serious injury
may result. The alkali solution will now heat up, due to the chemical
reaction taking place, while this is happening start melting your fatty
acids in a separate container made of stainless steel, glass, or
plastic. Do not use any aluminum when making soap. After the fatty
acids are liquefied, bring the temperature down to about 120 degrees.
Keep and eye on your alkali solution, when it also reaches 120 degrees
and they are both the same temperature, mix the alkali solution into
your fatty acids. Mix, and mix well. You will notice that the two
liquids which were clear before have now become cloudy. You have just
mixed water with oil, as everyone knows, water and oil separate, so you
will need to continue to mix until it "traces". Tracing is when you
notice that the solution is becoming more of a solid then a liquid and
can hold its own weight upon itself, simply take your mixing device and
pour some of the solution upon itself, and see it if sits on top,
creating an uneven surface. While you mix your water and oil, you it
will slowly turn into soap, molecule by molecule. It will speed up this
process if u add some already made soap, because soap helps make soap,
I never do this in my soap. Now that its tracing you need to add your
botanicals, like flower pedals, oatmeal, or pumice. Any dried and
crushed plant matter will make a great botanical. Also, add any scent
you wish to use, you can use essential oils or fragrance oils.
Fragrance oils are artificially created scents like cucumber melon for
example, i never use fragrance oils in my soap. Essential oils are
naturally extracted from plants, usually by distillation. Essential
oils are used in aromatheraphy and contain natural healing properties,
each one unique and special. All of my soaps contain essential oils.
Also you need to add any liquid coloring at this point, if your
coloring was a solid, perhaps incased in wax, you should of added it to
your melting fatty acids, since it is of such a small quantity it will
not hurt the production of soap, but usually u should add everything at
trace. Mix in your botanicals, scent, and color well. Pour into your
previously prepared mold which can be just about anything, a shoebox
works good for beginners. Line your shoebox with plastic, perhaps a
plastic garbage liner. I use a large wooden mold with no liner myself,
because liners will create unevenly shaped soap, especially the corner
pieces. Plastic or stainless steel would make the best molds. Cover
your mold after its had the soap poured into it with a blanket to keep
the heat in. You can use molds shaped like animals or even the empire
state building, they are more fun for the children. Now you must wait,
the question is however, how long. As you wait the solution turns
completely into soap, and solidifies. The rate at which this occurs
will vary depending on many things, mostly on what oils you used. The
more solid the oils u used the faster this process will go. Solid oils
include coconut oil, palm kernel oil, etc. Soft oils are those such as
olive oil or palm oil or any oil that is a liquid at room temperature.
The best animal fat to use is beef fat, also known as tallow after its
been processed. The soaps i make range from 7 hours (evergreen
mountain) of waiting for it to solidify, to 7 days (aromatic aloe).
Check on your soap by feeling the top for firmness. Be careful not to
open the mold to early when its still a liquid, and be careful not to
wait to long either, or it will become to hard to cut. Know that the
surface of the soap loaf will solidify faster then the center as the
water evaporates. If u were using a single soap mold, like those shaped
like hippo, lions, or penguins, you may just pop the soap out with your
thumb by pushing on the indented portion of the mold. If you were
making a "loaf" of soap its time to cut it now that its hard. Plop your
soap onto a cutting board and get a very long knife. cut into any shape
desired, have fun with it. Now place your soap bars and soap hippos
onto a drying rack, this can be anything that allows air to get to all
6 sides of your soap. I use stainless steel shelving racks, where the
shelves are made from wire, not plate. Allow your soap to "cure" for
about 1 month, during which your soap will lose all of its excess
water, shrinking it some and making it more stable. You may even stamp
a symbol or verbiage on the side of your soap. Your soap is beautiful,
good job, now why don’t u go wash up.
