A lesson in Soap making

Here is a little article I wrote up for a local newsletter.


 Let's explore all of the possibilities of making soap We know we need lye, water or other liquid, and fat of some kind.  But did you know that ANY naturally occurring oil from vegetable matter and ANY fat from animals, can end up as soap. One thing we don't use is any petroleum oil products.  They just don't saponify (turn into soap when combined with lye water). The most common oils used are olive oil, sunflower oil, corn oil, soy oil, coconut oil and rice bran oil. The other most important oil to use is castor oil, as it brings lovely creamy suds. Use at no more than 5 % of batch. The most common fats are lard, tallow and poultry fats. Lanolin from
sheep and many vegetable butters, such as shea , Brazil nut or mango are used regularly.
Additions to the soap can be fragrance oils, essential oils, botanicals, clays, and colorants.  The possibilities for creating are endless.  The ancients experimented with many different additions
during the Renaissance, using floral scents like rose, lavender, iris and marigold. Olive oils and animal fats were used most often.
  So, that being said, what do you want to make?  A great conditioning bar for your hands this winter, because we know that our hands are drier in the winter months? Or, a hard working
scrub bar for those dirty projects we all get into?  From a woman's point of view, what about a moisturizing beauty bar?     
  All right, we now have three possibilities for our soap making journey. But, knowing what you want to make is only the beginning. You must also consider the fats/oils that you want,
the kind of liquid to use, (water being the one used the most, but teas and milk are also used), what fragrance to use if any, and, the shape and size of your bar. There is an enormous choice of molds and other containers to choose from.  In my personal stash, I have cat face molds, dragon molds, Celtic scroll molds, guest soap molds, a log mold made from an old treadle sewing machine drawer, a flat wood mold, old freezer containers, yogurt cups, others.  Almost anything can be used, if, you can easily remove the soap from it after the proper cure time.
  One other important step to consider before beginning this journey, is whether or not you have the necessary solitary time needed to accomplish this task. Children under the age of 12
should never be around soap making.  Lye or Sodium Hydroxide is a very potent chemical that produces heat and breath-taking fumes when combined with an aqueous solution.  This is why
you must have latex gloves and protective eye-ware available. Combining the two must be accomplished under a strong exhaust hood or outside away from animals. And, remember: Never,
Never use aluminum to hold the mixture.  Having a safe and secure spot to allow it to set undisturbed until it cools down to the temperature necessary is also important.       
   For the beginner soap maker, (who is not averse to using animal fats), lard and beef tallow makes some of the whitest and hardest bars. A nice essential oil to use would be lavender or rose, as the animal fat scents will come through the soap making process and these help to mask the fragrance. There are so many available essential oils one can purchace, but a more cost effective alternative are fragrance oils, where you are then able to find certain florals that would be too expensive to get in pure essential oils, such as Lilac and Hyacinth.


    So, let's make soap.  Here are three easy recipes:

Lanolin Soap --very moisturizing


Ingredients:
  6 oz wt Hydrogenated Soybean Oil     Essential oil or fragrance
  5 oz wt Olive Oil                                    Oil of choice 
                                                                          .7 oz/# of oils
  4 oz wt Coconut Oil
  1 oz wt Lanolin
  2 oz wt sodium hydroxide
  6 fl oz water
      Instructions:
 Weigh all ingredients first. Stir sodium hydroxide into cool water. Stir until completely mixed. Set aside to cool.
 Combine all oils and heat gently to melt. When completely melted remove from heat.
      Since Lanolin is temperature sensitive, cool lye solution and oils to between 100°F and 110°F. Combine lye solution and oils. Stir until trace. Pour into shallow molds, cover lightly. When soap is firm, remove from mold, cut into bars and allow to cure in a warm area with good air circulation.
      Lightly Sandalwood is a good scent blend for this soap. Wrap in 4x6 Flat Bags and tie with jute. Makes about 20 to 22 oz of soap.


Salty Spa Bar # 2 --very good for cleaning your hands after working


40% Coconut  - 12.8 ounces            4.1 ounces of Lye
30% Castor     -   9.6 **                      9 ounces of liquid *see note
30% Crisco     -   9.6            approximately 14-16 ounces of med. Salt


 "Again half distilled water, half aloe for the liquid."  Scent of your choice.  Add your salts as desired. I like using a heavy hand with medium sea salt and a light hand with the coarse. You can add oats or not. Separately weigh lye and liquid. Add  lye to the water while under an exhaust hood and stir until liquid is clear. Set aside and allow to cool.  Weigh oils. Combine and heat to about 110 degrees F. When lye water reaches 110 degrees F, add to oils and stir to a trace. Add salts. Add scent.  Pour into molds. Let set for two days........   It's too simple, but it's a goodie! You have to let them cure. At least for two months.. They truly get better with age.                   **  This is one recipe where the amount of castor oil is increased due to the action of the salt.


Vinyard Raids III  -  creamy bar


Corn oil  - 16 ounces               6 ounces of Lye                      
Coconut oil - 12                    15 ounces distilled water                      
Rice bran oil  - 10.4              Essential oil or fragrance oil of choice
Castor oil      - 1.6                  7oz/# of oils                                  Weigh lye and water separately.  Add lye to water carefully under an exhaust hood, stirring constantly until liquid clears. Allow to cool to 55 to 65 degrees F.  Mix all oils together after weighing. Bring to 80-85 degrees F. When at correct temperatures, add lye water to oils and stir until mixture thickens to a trace.  Add scent and stir.  Pour into appropriate molds.  Allow to cure for at least 18 - 24 hours before removing from molds.  Please allow four weeks for curing time, before use. Enjoy.
