Unsaponifiable
Any plant oil or fat is mostly made up of esters of glycerol and saturated fatty acids. Another smaller component is a group of substances called unsaponifiables. Unsaponifiable means that the substance can't be decomposed into an acid, alcohol or salt, which makes it very beneficial to the skin. Unsaponifiables contain most of the healing properties.
What sets Shea Butter apart from other seed oils is its exceptionally percentage of unsapoifiables. In other seed oils, the unsaponifiable percentage, or healing fraction, is very small, often in the range of 1% or less. While these seed oils may have a good to excellent moisturizing fraction, they contain little or no healing capabilities, as the EFA's, important nuturients, Vitamins, and/or phytonutrients are saponified, or decomposed by the body.
Shea Butter has a higher amount of unsaponifiables than any other oil, between 7% and12%. The next highest is
Avocado oil, a well known skin conditioner, which has between 2% and 6% unsaponifiables.
These fatty acids are indispensable for moisturizing and retaining the elasticity of the skin. By making up for lipid deficiencies in the epidermal cells, Shea Butter provides the skin with all the essential elements it needs for its good balance and can treat many skin problems, including blemishes, wrinkles, itching, sunburns, small skin wounds, eczema, skin allergies, insect bites, frost bite, and other skin conditions. Unsaponifiables are also responsible for Shea Butter's excellent spreadability and almost instant absorption into the skin.
