Soap Making

Why We Make Soap

Our family has used handcrafted soaps over 10 years. In 2003 my first purchase was a slab of Lavender Soap from San Gimignano, Italy lovingly brought back home and shared with family and friends. Fast forward to winter of 2013 spent researching everything I could read on how to make handcrafted bar soap. The first batch was an Essentials Soap and I was hooked. Treehouse Soaps have a rustic, natural look to them and are made in small batches of 30 in my studio overlooking the lake in Haliburton. There are now over 40 varieties including unscented, baby, beer (from local micro breweries), vegan and even soap for our furry friends. I continue to enjoy the research, the making and ultimately the unwrap of each new batch.

Biolefin Wrap

Treehouse Soap now has a new wrap and label.

Virtues of the new wrap and label:

  • Clean look
  • Smell through and allows soap to breathe
  • Stays intact, no more belly band adjustment or band sliding off
  • Interesting soap features can be seen on back and sides
  • No soap bits on the customers nose or hands while they sniff and shop for soap.


Biolefin film is an oxo-biodegradable plastic.  This means that in the presence of oxygen and sunlight or heat, the plastic breaks down and changes into products that are then able to be decomposed by natural soil microorganisms like bacteria, fungi and algae. Because of these characteristics, this plastic will break down even in a landfill (where enough heat builds up) or if accidentally introduced into the environment as litter (due to the action of sunlight with oxygen). It can also go into community recycle bins.

Labels are from Forest Stewardship Council (FSC) Certified Papers & Recyclable Adhesive and are the first certified in the industry from GoGreen labels.

Soap History

How soap became soap. In 1000 B.C. Rome tells a story of women rinsing clothes in the river at the base of Sapo Hill, uphill animal sacrifice had taken place. The women noticed the clothes coming clean as they came in contact with the soapy clay oozing down the hill into the water. This cleansing substance was formed when the rendered animal fat (fats) soaked down through wood ashes (lye) and into the clay soil.


The Process

Soap making is a simple as dissolving sodium hydroxide in water, melting fats together, adding the sodium hydroxide (lye) to the melted fats and stirring. The fun begins when you use different fats, botanicals, and essential and/or fragrance oils. Lye Calculation should always be used to keep everything balanced.  In soap making, a carefully measured water/lye mixture is blended with natural oils in a process called saponification. Lye is simply an agent used to create soap from oils and water.

How Soap Cleans

How soap cleans is: Soap removes dirt and grease in two stages. First, it attaches itself to the dirt, then it suspends the dirt in lather until a rinse carries them both away. To clean skin or fabric, something must make the surface wet and attract the dirt away. Soap does both.
