"in the beginning, I researched the chemical qualities of different oils, the active properties of botanicals, the result of saponification and the physical properties of lather and bubbles.  The result of all my research is now known as Spencer's Farm Goat Milk Soap".

(-- Sydne Spencer --)



Sydne did her science research before making soap. She goes on to say, "I was hooked on making soap when I could use all the stuff I learned in college biochemistry to improve the quality of my soap."

SOAP SCIENCE FACTS and SCIENCE LESSONS

--  Handmade soaps are formulated using a combination of emollient oils and butters with lathering oils.  Olive and Avocado are popular emollient oils.  Cocoa and Shea butters are wonderful!  Coconut and Palm Kernel oils are super for lathering.  All of these oils are mixed with liquid saturated lye.

--  The chemical reaction between oil and lye is known as saponification.  Once saponification is complete there is no lye left in the mixture.  Each type of oil requires a different amount of lye to produce the complete reaction.  Today's savonnier has tools to calculate exact ratios of specific oils to lye, but the result is always soap and glycerin in approx. 3:1 ratio.

--  A simplified explanation of soap making chemistry is, one molecule of fat added to one molecule of lye yields three molecules of soap and one molecule of glycerin.

--  Use soap science definitions as a reference guide.




Great grandma had to make her own lye.  Today we have standardized lye available commercially.  Grandma rendered animal fats to get oils, so she was limited to tallow or lard.  Today we have all kinds of terrific oils to choose from!  Lard with olive and coconut oils makes wonderful, basic, castile soap.

Discover the history of soap making as far back as 2800 B.C.!

Before great grandma, history tells of soap-like materials tracing back to 2800 B.C. found in clay cylinders of ancient Babylon.  Soap formulas were inscribed on the clay.  Inscriptions mentioned fats were boiled with ashes, (a way of making soap), but there was no reference to the purpose.  Learn about the history of soap making!
